CASE: Transgender man consults gynecologist for fertility options

A 36-year-old transgender man considering the possibility of having his own biological children presents to the gynecology office to discuss hysterectomy as gender dysphoria treatment as well as his fertility preservation options. He has never had a gynecologic examination. Since age 24, he has been on testosterone therapy. Although his menses initially ceased, each month over the past 2 years he has had breakthrough spotting lasting 2 to 4 days, sometimes accompanied by pelvic pain and cramping. These symptoms have caused him distress and anxiety, which have led to his missing work 1 to 3 days each month. On presentation, he appears anxious and makes little eye contact. His girlfriend of 6 years has come in with him and is very supportive.

Over the past decade, transgender health care has moved to the forefront of the medical conversation. At many prominent medical centers across the United States, clinicians are forming multidisciplinary teams to help improve the health care of this patient population. Outcomes are being studied, and the literature is becoming more robust.

People tend to think of transgender women—male-assigned persons who self-identify as female—as the typical prototype for transgender people, but this focus is skewed in both society and the medical community. Transgender men—female-assigned persons who self-identify as male—remain underrepresented, mostly because they want to stay “under the radar,” especially with respect to medical care and, more specifically, routine gynecologic care.

Although the transgender woman has unique health needs and may present to a gynecologist for care after gender-affirmationsurgery, the transgender man’s many health care needs and their subtleties can be addressed only by a gynecologist. In this article, I review these intricacies of care to help increase clinician comfort in treating these patients.

Why transgender patients may delay seeking health care

Transgender patients remain underserved because of the health care barriers they encounter. Factors contributing to poor access include lack of health insurance, inability to pay for services, clinician insensitivity and hostility, and fear of exposure of transgender status during health care encounters.¹ In a recent large survey study, 30% of transgender respondents indicated that they delayed or did not seek medical care as a result of discrimination, and those who had needed to teach their clinicians about transgenderism were 4 times more likely to postpone or not seek care.²

In a 2015 survey of ObGyns’ current knowledge and practice regarding LGBT (lesbian, gay, bisexual, transgender) care, only one-third of respondents indicated they were comfortable caring for transgender patients.³ In addition, only one-third indicated being knowledgeable about the steps transgender patients must take to transition to their self-identified gender, and less than half were familiar with the recommendations for the routine health maintenance and screening of these patients.

Much of this discomfort derives from the lack of incorporation of LGBT-specific topics in medical curricula. In 2011, Obedin-Maliver and colleagues found that, at 176 US and Canadian allopathic and osteopathic medical schools, the median time dedicated to LGBT health care needs and related topics was unsatisfactory.⁴ This deficiency is slowly being reduced with changes in the curricula of many health care specialties. In ObGyn residency programs, for example, transgender-specific questions have been added to annual in-service examinations. The hope is that, as education initiatives improve, clinicians will become more comfortable caring for gender-minority patients, who with improved access to care will no longer need to seek subspecialists in transgender services.

Considerations for the gynecologic visit and examination

Transgender men visit the gynecology office for many reasons, including routine gynecologic care and health maintenance, care for acute and chronic gynecologic conditions (abnormal bleeding, pelvic pain, vaginitis), evaluation and management of pelvic floor disorders, consultation on hysterectomy for gender transition, and fertility counseling.

However, transgender men who reach their third, fourth, or fifth decade without having had a pelvic examination cite many reasons for avoiding the gynecology office. Most commonly, gynecologic visits and genital examination can severely exacerbate these patients’ gender dysphoria. In addition, many patients who do not engage in penetrative vaginal sex think their health risks are so low that they can forgo or delay pelvic exams. Patients who have stopped menstruating while on testosterone therapy may think there is no need for routine gynecologic care. Other reasons for avoiding pelvic exams are pain and traumatic sexual memories.⁵

Four pillars of a successful practice: 4. Motivate your staff

Transgender men need to receive the regular guideline-recommended pelvic exams and screenings used for cisgender women. (Cisgender refers to a person whose sense of gender identity corresponds with their birth sex.) We need to educate patients in this regard and to discuss several issues before performing an examination. First, take a thorough history and avoid making assumptions about sexual orientation and sex practices. Some patients have penetrative vaginal intercourse with either men or women. For some patients, the exam may cause dysphoria symptoms, and we need to validate patients’ fears. Discussing these issues ahead of time helps patients get used to the idea of undergoing an exam and assures them that the clinician is experienced in performing these exams for transgender men. In my practice, we explain the exam’s purpose (screening or diagnosis) and importance. We also counsel patients that they may experience some normal, and temporary, spotting after the exam. For those who experience severe dysphoria with vaginal bleeding of any kind, we acknowledge that postexam spotting may cause some anxiety. Patients with severe anxiety before the exam may be premedicated with an anxiolytic agent as long as someone can transport them to and from the office.

The bimanual exam should be performed with care and efficiency and with the patient given as much control as possible. In most cases, we ask patients to undress only from the waist down, and their genitals stay covered. Patients uncomfortable in stirrups are asked to show us the position that suits them best, and we try to accommodate them. Although speed is a goal, remember that many patients are nulliparous, have had limited or no vaginal penetration, or are on testosterone and have significant vaginal dryness. Use the smallest speculum possible, a pediatric or long and narrow adult speculum, and apply lubricant copiously. Pre-exam application of topical lidocaine jelly to the introitus can help reduce pain. To help a patient relax the pelvic floor muscles and habituate to the presence of a foreign object in the vagina, start the exam by inserting a single digit. In addition, ask the patient about speculum placement inside the vagina: Does he want to place the speculum himself or guide the clinician’s hand? Open the speculum only as much as needed to adequately visualize the cervix and then remove it with care.

Managing benign gynecologic disorders

The same algorithms are used to evaluate abnormal bleeding in all patients, but the differential diagnosis expands for those on testosterone therapy. Testosterone may no longer be suppressing their cycles, and abnormal bleeding could simply be the return of menses, which would present as regular cyclic bleeding. Increasing the testosterone dosing or changing the testosterone formulation may help, and the gynecologist should discuss these options with the patient’s prescribing clinician. In addition, progesterone in any form (for example, medroxyprogesterone acetate 5 to 30 mg daily) can be added to testosterone regimens to help suppress menses. The levonorgestrel-releasing intrauterine device (LNG-IUD) can be very effective, but placement can induce anxiety, and some patients decline this treatment option.

In patients with intermenstrual spotting, assess the vagina for atrophy. Both over-the-counter vaginal moisturizers and DHEA (dehydroepiandrosterone) suppositories (1% compounded) can help treat atrophy, but not all patients are comfortable using them. Most patients decline vaginal estrogen products for symptomatic vaginal atrophy even though the systemic effects are minimal.

The historic literature suggests that female-to-male patients’ long-term exposure to androgens leads to atrophic changes in the endometrium and myometrium, and clinical studies of menopausal women who take exogenous androgens have confirmed this effect.⁶ However, new data point to a different histologic scenario. A recent study found a possible association between long-term testosterone use in transgender men of reproductive age and a low proliferative active endometrium, as well as hypertrophic changes in the myometrium.⁷ The causes may be peripheral aromatization of androgens and expression and up-regulation of androgen receptors within the endometrial stroma and myometrial cells.⁸ Given these emerging data and anecdotal cases reported by clinicians who perform hysterectomies for transgender men, imaging and tissue sampling should be used to evaluate abnormal uterine bleeding, particularly in patients previously amenorrheic on testosterone. Be aware that transvaginal ultrasound or endometrial biopsy are challenging procedures for these patients. Counsel patients to ensure that they adhere to follow-up.

The ongoing need for cervical cancer screening

The concept of “original gender surveillance” was presented in a 2-case series of transgender men with uterine and cervical cancer that might have been detected earlier with better screening and routine care.⁹ There is no evidence, however, that long-term high-dose androgen therapy causes endometrial or cervical cancer,¹⁰ and the data on endometrial cancer in patients on cross-sex hormone therapy are limited such that a causal relationship between testosterone and these malignancies cannot be established.^9,11–14

The rate of unsatisfactory Pap smears is higher in transgender men than in cisgender women. The difference was anecdotally noted by clinicians who routinely cared for transgender patients over time and was confirmed with a retrospective chart review.¹⁵

Peitzmeier and colleagues reviewed the records of 233 transgender men and 3,625 cisgender women with Pap tests performed at an urban community health center over 6 years.¹⁵ The transgender cohort, with its prevalence rate of 10%, was 10 times more likely to have an unsatisfactory or inadequate Pap smear. Moreover, the transgender patients were more likely to have longer latency to follow-up for a repeat Pap test. In addition, testosterone therapy was more likely associated with inadequate Pap smears, and time on testosterone therapy was associated with higher odds of Pap smear inadequacy. Besides the exogenous hormone therapy, clinician comfort level and experience may have contributed to the high prevalence of inadequate Pap smears.

As mentioned earlier, it is important to become comfortable performing pelvic exams for transgender men and to prepare patients for the possibility that a Pap smear might be inadequate, making a follow-up visit and repeat Pap test necessary.¹⁶

Read about hysterectomy, oophorectomy, and vaginectomy choices

Consultation for hysterectomy: Perioperative considerations

Transgender men may undergo hysterectomy, oophorectomy, and/or vaginectomy. The TABLE summarizes the indications and perioperative considerations for each procedure.

Some transgender men undergo hysterectomy for benign gynecologic disease. Counseling and perioperative planning are the same for these patients as for cisgender women, although some of the considerations discussed here remain important.

Other patients undergo hysterectomy as part of transitioning to their self-affirmed gender. The World Professional Association for Transgender Health (WPATH) Standards of Care should be used to guide counseling and treatment.¹⁷ These guidelines were designed as a framework for performing hysterectomy and other gender-affirming procedures. According to the WPATH standards, the criteria for hysterectomy and oophorectomy are:

• 2 referral letters from qualified mental health professionals
• well-documented persistent gender dysphoria
• capacity to make fully informed decisions and to consent to treatment
• age of majority in given country
• good control of any concurrent medical or mental health concerns, and
• hormone therapy for 12 continuous months, as appropriate to gender goals, unless the patient has a medical contraindication or is otherwise unable or unwilling to take hormones.

As the guidelines emphasize, these criteria do not apply to patients undergoing either procedure for medical indications other than gender dysphoria.

Hysterectomy approach. Most surgeons perform gender-affirming hysterectomies laparoscopically. Many clinicians hesitate to perform these hysterectomies vaginally, as the patients are often nulliparous. In general, the best operative route is the one the surgeon feels most comfortable performing safely and efficiently. For a nulliparous patient with minimal pelvic organ descensus and a narrow pelvis, the laparoscopic approach is reasonable. A recent study in a small cohort of transgender men found that vaginal hysterectomy was successful in only 1 in 4 patients.¹⁸ Nevertheless, the American College of Obstetricians and Gynecologists (ACOG) recommends vaginal hysterectomy, when appropriate, for limiting complications and morbidity while maximizing cost-effectiveness.¹⁹ Although data are limited, vaginal hysterectomy seems feasible and should be considered in a subset of patients who pre‑sent for gender-affirming hysterectomy.

The oophorectomy debate

Oophorectomy concurrent with hysterectomy remains a topic of debate among gynecologists who perform hysterectomy for gender transition. Some clinicians think gonadectomy poses a significant risk for bone health compromise at an early age. The long-term effects of testosterone on bone have not been well studied. Although bone metabolism is thought to increase over the short term, there are no major changes in bone density over the long term. In fact, in the setting of long-term testosterone therapy, cortical bone was found to be larger in transgender men than in cisgender women.²⁰ The issue is for patients who stop taking exogenous testosterone after oophorectomy. This subset of patients has not been well studied but clearly needs bone health surveillance and supplementation.

Another concern about oophorectomy is its effect on fertility. Because it is important to discuss fertility-preserving options, during consultation for a hysterectomy I spend a large portion of time addressing fertility goals. Patients who want to become a parent but do not want to carry a child (they want a current or future partner or surrogate to carry) are candidates for hysterectomy; those who do not want a genetic child are candidates for oophorectomy; and those who do not want to preserve their fertility (or have already ended it) and who meet the WPATH criteria for surgery are candidates for oophorectomy concurrent with hysterectomy. The discussion can be particularly challenging with young transgender men, since their ability to project their family planning goals may be compromised by their gender dysphoria. Clinicians can counsel patients about another option: isolated hysterectomy with subsequent staged oophorectomy.

Similar to cisgender women with polycystic ovary syndrome, transgender men on exogenous testosterone therapy are at risk for ovarian cysts,⁷ which can cause pain and should be evaluated and managed. As mentioned, these patients may find it difficult to visit a gynecologist and tolerate a vaginal examination, and many fear presenting to an emergency room, as they will need to disclose their transgender status and risk being discriminated against or, worse, not being triaged or cared for properly. Patients should be thoroughly counseled about the risks and benefits of having oophorectomy performed concurrently with hysterectomy.

The question of vaginectomy

Patients and clinicians often ask about concurrent vaginectomy procedures. In some cases, patients with severe gender dysphoria and absence of penetrative vaginal activity request excision or obliteration of the vagina. There is no standard of care, however. Vaginectomy can be done transvaginally or abdominally: open, laparoscopically, or robotically. It therefore should be performed by surgeons experienced in the procedure. Patients should be advised that a portion of the vaginal epithelium is sometimes used for certain phalloplasty procedures and that, if they are considering genital reconstruction in the future, it may be beneficial to preserve the vagina until that time.

There are no guidelines on stopping or continuing testosterone therapy perioperatively. Some clinicians are concerned about possible venous thromboembolic events related to perioperative use of testosterone, but there are no data supporting increased risk. The risk of postoperative vaginal cuff bleeding in patients on and off testosterone has not been well studied. Since patients who stop taking testosterone may develop severe mood swings and malaise, they should be counseled on recognizing and managing such changes. There are also no data on the risk of vaginal cuff dehiscence in this patient population. Testosterone usually causes the vagina to become very atrophic, so proper closure should be ensured to avoid cuff evisceration. In my practice, the vaginal cuff is closed in 2 layers using at least 1 layer of delayed absorbable suture.

Addressing fertility, contraception, and obstetric care

Most transgender men are able to conceive a child.²¹ Data in this area, however, are sparse. Most of the literature on reproductive health in this patient population is focused on human immunodeficiency virus (HIV) and other sexually transmitted infections.²² Nevertheless, patient-physician dialogue on fertility and reproductive health has increased since more patients started seeking surgical transition services (likely a result of improved coverage for these surgeries). In addition, we are learning more about patients’ ability and desire to conceive after long-term use of cross-sex hormone therapy. The importance of this dialogue is becoming apparent. One survey study found that more than half of the transgender men who had undergone affirmation surgery wanted to become parents.²³

Before initiating cross-sex hormone therapy or before undergoing hysterectomy and/or oophorectomy, patients must be counseled about their fertility options. Testosterone may affect fertility and fecundity, but there are case reports of successful pregnancy after discontinuation of testosterone.²¹ Reproductive endocrinology and fertility specialists have begun to recognize the importance of fertility preservation in this patient population and to apply the principles of oncofertility care beyond patients with cancer. In a 2015 opinion paper on access to fertility services by transgender persons, the Ethics Committee of the American Society for Reproductive Medicine focused on this population’s unique fertility needs.²⁴ Currently, oocyte and embryo cryopreservation are options for transgender men planning to start cross-sex hormones or undergo surgery.²⁵ Other methods being investigated may become options in the future.²⁵

There are even fewer data on transgender men’s contraceptive needs. Many clinicians mistakenly think these patients are at low risk for pregnancy. Some patients have male partners and engage in penetrative penile-vaginal intercourse; others are not on testosterone therapy; and still others, despite taking testosterone, are not always amenorrheic and may be ovulating. In a small cross-sectional study, Light and colleagues found that 12% of transgender men who were surveyed after conceiving had been amenorrheic on testosterone therapy, and 24% of these pregnancies were not planned.²¹

In a study by Cipres and colleagues, half of the 26 transgender men were considered at risk for pregnancy: These patients still had a uterus, not all were on testosterone, not all on testosterone were amenorrheic, they were having vaginal intercourse with cisgender men, and none were using condoms or other contraception.²⁶ The authors noted several potential underlying reasons for poor counseling on contraceptive needs: patients feel stigmatized, clinicians assume these patients are not candidates for “female” hormone therapy, patients fear these modalities may feminize them and compromise their affirmed identities, patients poorly understand how testosterone works and have mistaken ideas about its contraceptive properties, and clinician discomfort with broaching fertility and reproductive health discussions.

Data are also limited on pregnancy in transgender men. We do know that clinicians are not well equipped to help patients during the peripartum period and better resources are needed.²¹ Gender dysphoria can worsen during and immediately after pregnancy, and patients may be at significant risk for postpartum depression. More research is needed.

In my practice, the vaginal cuff is closed in 2 layers using at least 1 layer of delayed absorbable suture.

Addressing fertility, contraception, and obstetric care

Most transgender men are able to conceive a child.²¹ Data in this area, however, are sparse. Most of the literature on reproductive health in this patient population is focused on human immunodeficiency virus (HIV) and other sexually transmitted infections.²² Nevertheless, patient-physician dialogue on fertility and reproductive health has increased since more patients started seeking surgical transition services (likely a result of improved coverage for these surgeries). In addition, we are learning more about patients’ ability and desire to conceive after long-term use of cross-sex hormone therapy. The importance of this dialogue is becoming apparent. One survey study found that more than half of the transgender men who had undergone affirmation surgery wanted to become parents.²³

Before initiating cross-sex hormone therapy or before undergoing hysterectomy and/or oophorectomy, patients must be counseled about their fertility options. Testosterone may affect fertility and fecundity, but there are case reports of successful pregnancy after discontinuation of testosterone.²¹ Reproductive endocrinology and fertility specialists have begun to recognize the importance of fertility preservation in this patient population and to apply the principles of oncofertility care beyond patients with cancer. In a 2015 opinion paper on access to fertility services by transgender persons, the Ethics Committee of the American Society for Reproductive Medicine focused on this population’s unique fertility needs.²⁴ Currently, oocyte and embryo cryopreservation are options for transgender men planning to start cross-sex hormones or undergo surgery.²⁵ Other methods being investigated may become options in the future.²⁵

There are even fewer data on transgender men’s contraceptive needs. Many clinicians mistakenly think these patients are at low risk for pregnancy. Some patients have male partners and engage in penetrative penile-vaginal intercourse; others are not on testosterone therapy; and still others, despite taking testosterone, are not always amenorrheic and may be ovulating. In a small cross-sectional study, Light and colleagues found that 12% of transgender men who were surveyed after conceiving had been amenorrheic on testosterone therapy, and 24% of these pregnancies were not planned.²¹

In a study by Cipres and colleagues, half of the 26 transgender men were considered at risk for pregnancy: These patients still had a uterus, not all were on testosterone, not all on testosterone were amenorrheic, they were having vaginal intercourse with cisgender men, and none were using condoms or other contraception.²⁶ The authors noted several potential underlying reasons for poor counseling on contraceptive needs: patients feel stigmatized, clinicians assume these patients are not candidates for “female” hormone therapy, patients fear these modalities may feminize them and compromise their affirmed identities, patients poorly understand how testosterone works and have mistaken ideas about its contraceptive properties, and clinician discomfort with broaching fertility and reproductive health discussions.

Data are also limited on pregnancy in transgender men. We do know that clinicians are not well equipped to help patients during the peripartum period and better resources are needed.²¹ Gender dysphoria can worsen during and immediately after pregnancy, and patients may be at significant risk for postpartum depression. More research is needed.

CASE: Transgender man consults gynecologist for fertility options

A 36-year-old transgender man considering the possibility of having his own biological children presents to the gynecology office to discuss hysterectomy as gender dysphoria treatment as well as his fertility preservation options. He has never had a gynecologic examination. Since age 24, he has been on testosterone therapy. Although his menses initially ceased, each month over the past 2 years he has had breakthrough spotting lasting 2 to 4 days, sometimes accompanied by pelvic pain and cramping. These symptoms have caused him distress and anxiety, which have led to his missing work 1 to 3 days each month. On presentation, he appears anxious and makes little eye contact. His girlfriend of 6 years has come in with him and is very supportive.

Over the past decade, transgender health care has moved to the forefront of the medical conversation. At many prominent medical centers across the United States, clinicians are forming multidisciplinary teams to help improve the health care of this patient population. Outcomes are being studied, and the literature is becoming more robust.

People tend to think of transgender women—male-assigned persons who self-identify as female—as the typical prototype for transgender people, but this focus is skewed in both society and the medical community. Transgender men—female-assigned persons who self-identify as male—remain underrepresented, mostly because they want to stay “under the radar,” especially with respect to medical care and, more specifically, routine gynecologic care.

Although the transgender woman has unique health needs and may present to a gynecologist for care after gender-affirmationsurgery, the transgender man’s many health care needs and their subtleties can be addressed only by a gynecologist. In this article, I review these intricacies of care to help increase clinician comfort in treating these patients.

Why transgender patients may delay seeking health care

Transgender patients remain underserved because of the health care barriers they encounter. Factors contributing to poor access include lack of health insurance, inability to pay for services, clinician insensitivity and hostility, and fear of exposure of transgender status during health care encounters.¹ In a recent large survey study, 30% of transgender respondents indicated that they delayed or did not seek medical care as a result of discrimination, and those who had needed to teach their clinicians about transgenderism were 4 times more likely to postpone or not seek care.²

In a 2015 survey of ObGyns’ current knowledge and practice regarding LGBT (lesbian, gay, bisexual, transgender) care, only one-third of respondents indicated they were comfortable caring for transgender patients.³ In addition, only one-third indicated being knowledgeable about the steps transgender patients must take to transition to their self-identified gender, and less than half were familiar with the recommendations for the routine health maintenance and screening of these patients.

Much of this discomfort derives from the lack of incorporation of LGBT-specific topics in medical curricula. In 2011, Obedin-Maliver and colleagues found that, at 176 US and Canadian allopathic and osteopathic medical schools, the median time dedicated to LGBT health care needs and related topics was unsatisfactory.⁴ This deficiency is slowly being reduced with changes in the curricula of many health care specialties. In ObGyn residency programs, for example, transgender-specific questions have been added to annual in-service examinations. The hope is that, as education initiatives improve, clinicians will become more comfortable caring for gender-minority patients, who with improved access to care will no longer need to seek subspecialists in transgender services.

Considerations for the gynecologic visit and examination

Transgender men visit the gynecology office for many reasons, including routine gynecologic care and health maintenance, care for acute and chronic gynecologic conditions (abnormal bleeding, pelvic pain, vaginitis), evaluation and management of pelvic floor disorders, consultation on hysterectomy for gender transition, and fertility counseling.

However, transgender men who reach their third, fourth, or fifth decade without having had a pelvic examination cite many reasons for avoiding the gynecology office. Most commonly, gynecologic visits and genital examination can severely exacerbate these patients’ gender dysphoria. In addition, many patients who do not engage in penetrative vaginal sex think their health risks are so low that they can forgo or delay pelvic exams. Patients who have stopped menstruating while on testosterone therapy may think there is no need for routine gynecologic care. Other reasons for avoiding pelvic exams are pain and traumatic sexual memories.⁵

Four pillars of a successful practice: 4. Motivate your staff

Transgender men need to receive the regular guideline-recommended pelvic exams and screenings used for cisgender women. (Cisgender refers to a person whose sense of gender identity corresponds with their birth sex.) We need to educate patients in this regard and to discuss several issues before performing an examination. First, take a thorough history and avoid making assumptions about sexual orientation and sex practices. Some patients have penetrative vaginal intercourse with either men or women. For some patients, the exam may cause dysphoria symptoms, and we need to validate patients’ fears. Discussing these issues ahead of time helps patients get used to the idea of undergoing an exam and assures them that the clinician is experienced in performing these exams for transgender men. In my practice, we explain the exam’s purpose (screening or diagnosis) and importance. We also counsel patients that they may experience some normal, and temporary, spotting after the exam. For those who experience severe dysphoria with vaginal bleeding of any kind, we acknowledge that postexam spotting may cause some anxiety. Patients with severe anxiety before the exam may be premedicated with an anxiolytic agent as long as someone can transport them to and from the office.

The bimanual exam should be performed with care and efficiency and with the patient given as much control as possible. In most cases, we ask patients to undress only from the waist down, and their genitals stay covered. Patients uncomfortable in stirrups are asked to show us the position that suits them best, and we try to accommodate them. Although speed is a goal, remember that many patients are nulliparous, have had limited or no vaginal penetration, or are on testosterone and have significant vaginal dryness. Use the smallest speculum possible, a pediatric or long and narrow adult speculum, and apply lubricant copiously. Pre-exam application of topical lidocaine jelly to the introitus can help reduce pain. To help a patient relax the pelvic floor muscles and habituate to the presence of a foreign object in the vagina, start the exam by inserting a single digit. In addition, ask the patient about speculum placement inside the vagina: Does he want to place the speculum himself or guide the clinician’s hand? Open the speculum only as much as needed to adequately visualize the cervix and then remove it with care.

Managing benign gynecologic disorders

The same algorithms are used to evaluate abnormal bleeding in all patients, but the differential diagnosis expands for those on testosterone therapy. Testosterone may no longer be suppressing their cycles, and abnormal bleeding could simply be the return of menses, which would present as regular cyclic bleeding. Increasing the testosterone dosing or changing the testosterone formulation may help, and the gynecologist should discuss these options with the patient’s prescribing clinician. In addition, progesterone in any form (for example, medroxyprogesterone acetate 5 to 30 mg daily) can be added to testosterone regimens to help suppress menses. The levonorgestrel-releasing intrauterine device (LNG-IUD) can be very effective, but placement can induce anxiety, and some patients decline this treatment option.

In patients with intermenstrual spotting, assess the vagina for atrophy. Both over-the-counter vaginal moisturizers and DHEA (dehydroepiandrosterone) suppositories (1% compounded) can help treat atrophy, but not all patients are comfortable using them. Most patients decline vaginal estrogen products for symptomatic vaginal atrophy even though the systemic effects are minimal.

The historic literature suggests that female-to-male patients’ long-term exposure to androgens leads to atrophic changes in the endometrium and myometrium, and clinical studies of menopausal women who take exogenous androgens have confirmed this effect.⁶ However, new data point to a different histologic scenario. A recent study found a possible association between long-term testosterone use in transgender men of reproductive age and a low proliferative active endometrium, as well as hypertrophic changes in the myometrium.⁷ The causes may be peripheral aromatization of androgens and expression and up-regulation of androgen receptors within the endometrial stroma and myometrial cells.⁸ Given these emerging data and anecdotal cases reported by clinicians who perform hysterectomies for transgender men, imaging and tissue sampling should be used to evaluate abnormal uterine bleeding, particularly in patients previously amenorrheic on testosterone. Be aware that transvaginal ultrasound or endometrial biopsy are challenging procedures for these patients. Counsel patients to ensure that they adhere to follow-up.

2017 Update on cervical disease

The ongoing need for cervical cancer screening

The concept of “original gender surveillance” was presented in a 2-case series of transgender men with uterine and cervical cancer that might have been detected earlier with better screening and routine care.⁹ There is no evidence, however, that long-term high-dose androgen therapy causes endometrial or cervical cancer,¹⁰ and the data on endometrial cancer in patients on cross-sex hormone therapy are limited such that a causal relationship between testosterone and these malignancies cannot be established.^9,11–14

The rate of unsatisfactory Pap smears is higher in transgender men than in cisgender women. The difference was anecdotally noted by clinicians who routinely cared for transgender patients over time and was confirmed with a retrospective chart review.¹⁵

Peitzmeier and colleagues reviewed the records of 233 transgender men and 3,625 cisgender women with Pap tests performed at an urban community health center over 6 years.¹⁵ The transgender cohort, with its prevalence rate of 10%, was 10 times more likely to have an unsatisfactory or inadequate Pap smear. Moreover, the transgender patients were more likely to have longer latency to follow-up for a repeat Pap test. In addition, testosterone therapy was more likely associated with inadequate Pap smears, and time on testosterone therapy was associated with higher odds of Pap smear inadequacy. Besides the exogenous hormone therapy, clinician comfort level and experience may have contributed to the high prevalence of inadequate Pap smears.

As mentioned earlier, it is important to become comfortable performing pelvic exams for transgender men and to prepare patients for the possibility that a Pap smear might be inadequate, making a follow-up visit and repeat Pap test necessary.¹⁶

Read about hysterectomy, oophorectomy, and vaginectomy choices

Consultation for hysterectomy: Perioperative considerations

Transgender men may undergo hysterectomy, oophorectomy, and/or vaginectomy. The TABLE summarizes the indications and perioperative considerations for each procedure.

Some transgender men undergo hysterectomy for benign gynecologic disease. Counseling and perioperative planning are the same for these patients as for cisgender women, although some of the considerations discussed here remain important.

Other patients undergo hysterectomy as part of transitioning to their self-affirmed gender. The World Professional Association for Transgender Health (WPATH) Standards of Care should be used to guide counseling and treatment.¹⁷ These guidelines were designed as a framework for performing hysterectomy and other gender-affirming procedures. According to the WPATH standards, the criteria for hysterectomy and oophorectomy are:

• 2 referral letters from qualified mental health professionals
• well-documented persistent gender dysphoria
• capacity to make fully informed decisions and to consent to treatment
• age of majority in given country
• good control of any concurrent medical or mental health concerns, and
• hormone therapy for 12 continuous months, as appropriate to gender goals, unless the patient has a medical contraindication or is otherwise unable or unwilling to take hormones.

As the guidelines emphasize, these criteria do not apply to patients undergoing either procedure for medical indications other than gender dysphoria.

Hysterectomy approach. Most surgeons perform gender-affirming hysterectomies laparoscopically. Many clinicians hesitate to perform these hysterectomies vaginally, as the patients are often nulliparous. In general, the best operative route is the one the surgeon feels most comfortable performing safely and efficiently. For a nulliparous patient with minimal pelvic organ descensus and a narrow pelvis, the laparoscopic approach is reasonable. A recent study in a small cohort of transgender men found that vaginal hysterectomy was successful in only 1 in 4 patients.¹⁸ Nevertheless, the American College of Obstetricians and Gynecologists (ACOG) recommends vaginal hysterectomy, when appropriate, for limiting complications and morbidity while maximizing cost-effectiveness.¹⁹ Although data are limited, vaginal hysterectomy seems feasible and should be considered in a subset of patients who pre‑sent for gender-affirming hysterectomy.

Related Article:
Total laparoscopic versus laparoscopic supracervical hysterectomy

The oophorectomy debate

Oophorectomy concurrent with hysterectomy remains a topic of debate among gynecologists who perform hysterectomy for gender transition. Some clinicians think gonadectomy poses a significant risk for bone health compromise at an early age. The long-term effects of testosterone on bone have not been well studied. Although bone metabolism is thought to increase over the short term, there are no major changes in bone density over the long term. In fact, in the setting of long-term testosterone therapy, cortical bone was found to be larger in transgender men than in cisgender women.²⁰ The issue is for patients who stop taking exogenous testosterone after oophorectomy. This subset of patients has not been well studied but clearly needs bone health surveillance and supplementation.

Another concern about oophorectomy is its effect on fertility. Because it is important to discuss fertility-preserving options, during consultation for a hysterectomy I spend a large portion of time addressing fertility goals. Patients who want to become a parent but do not want to carry a child (they want a current or future partner or surrogate to carry) are candidates for hysterectomy; those who do not want a genetic child are candidates for oophorectomy; and those who do not want to preserve their fertility (or have already ended it) and who meet the WPATH criteria for surgery are candidates for oophorectomy concurrent with hysterectomy. The discussion can be particularly challenging with young transgender men, since their ability to project their family planning goals may be compromised by their gender dysphoria. Clinicians can counsel patients about another option: isolated hysterectomy with subsequent staged oophorectomy.

Similar to cisgender women with polycystic ovary syndrome, transgender men on exogenous testosterone therapy are at risk for ovarian cysts,⁷ which can cause pain and should be evaluated and managed. As mentioned, these patients may find it difficult to visit a gynecologist and tolerate a vaginal examination, and many fear presenting to an emergency room, as they will need to disclose their transgender status and risk being discriminated against or, worse, not being triaged or cared for properly. Patients should be thoroughly counseled about the risks and benefits of having oophorectomy performed concurrently with hysterectomy.

Vaginal hysterectomy with basic instrumentation

The question of vaginectomy

Patients and clinicians often ask about concurrent vaginectomy procedures. In some cases, patients with severe gender dysphoria and absence of penetrative vaginal activity request excision or obliteration of the vagina. There is no standard of care, however. Vaginectomy can be done transvaginally or abdominally: open, laparoscopically, or robotically. It therefore should be performed by surgeons experienced in the procedure. Patients should be advised that a portion of the vaginal epithelium is sometimes used for certain phalloplasty procedures and that, if they are considering genital reconstruction in the future, it may be beneficial to preserve the vagina until that time.

There are no guidelines on stopping or continuing testosterone therapy perioperatively. Some clinicians are concerned about possible venous thromboembolic events related to perioperative use of testosterone, but there are no data supporting increased risk. The risk of postoperative vaginal cuff bleeding in patients on and off testosterone has not been well studied. Since patients who stop taking testosterone may develop severe mood swings and malaise, they should be counseled on recognizing and managing such changes. There are also no data on the risk of vaginal cuff dehiscence in this patient population. Testosterone usually causes the vagina to become very atrophic, so proper closure should be ensured to avoid cuff evisceration. In my practice, the vaginal cuff is closed in 2 layers using at least 1 layer of delayed absorbable suture.

CASE: Gynecologist accused of placing an IUD without performing a pregnancy test

A 34-year-old woman (G4 P3013) presents to her gynecologist for planned placement of the Mirena Intrauterine System (Bayer HealthCare). She was divorced 2 months ago and is interested in birth control. She smokes 1.5 packs per day, and her history includes irregular menses, an earlier Pap smear result of atypical squamous cells of undetermined significance (ASCUS) with negative colposcopy results, polycystic ovary syndrome, obesity, migraine headaches with aura, bilateral carpel tunnel surgery, and a herniated L4.5 disc treated conservatively. She has no history of any psychiatric problems.

One week before intrauterine device (IUD) placement, she discussed the options with her gynecologist and received a Mirena patient brochure. At the office visit for IUD placement, the patient stated she had a negative home pregnancy test 1 week earlier. She did not tell the gynecologist that she had taken Plan B One-Step (levonorgestrel, 1.5 mg) emergency contraception 2 weeks prior to presenting to her gynecologist after receiving it from a Planned Parenthood office following condom breakage during coitus. IUD placement was uncomplicated.

After noting spotting several weeks later, she contacted her gynecologist’s office. Results of an office urine pregnancy test were positive; the serum human chorionic gonadotropin (hCG) level was reported at 65,000 mIU/mL.The results of a pelvic sonogram showed a 12 5/7-week intrauterine gestation. The gynecologist unsuccessfully tried to remove the IUD. Options for termination or continuation of the pregnancy were discussed. The patient felt the gynecologist strongly encouraged, “almost insisting on,” termination. Termination could not be performed locally as her state laws did not allow second trimester abortion; the gynecologist provided out-of-state clinic options.

The patient aborted the pregnancy in a neighboring state. She was opposed to the termination but decided it was not a good time for her to have a baby. She felt the staff at the facility were “cold” and had a “we got to get this done attitude.” As she left the clinic, she saw people picketing outside and found the whole process “psychologically traumatic.” When bleeding persisted, she sought care from another gynecologist. Pelvic sonography results showed retained products of conception (POC). The new gynecologist performed operative hysteroscopy to remove the POC. The patient became depressed and felt as if she was a victim of pain and suffering.

The patient’s attorney filed a medical malpractice claim against the gynecologist who inserted the IUD, accusing her of negligence for not performing a pregnancy test immediately before IUD insertion.

In a deposition, the patient stated she bought the home pregnancy test in a “dollar store” and was worried about its accuracy, but never told the gynecologist. Conception probably occurred 2 weeks prior to IUD insertion, correlating with the broken condom and taking of Plan B. She did not think the gynecologist needed to know this as it “would not have made any difference in her care.”

The gynecologist confirmed that the patient’s record included “Patient stated ‘pregnancy test negative within 1 week of IUD placement.’” The gynecologist did not feel that obtaining the date of the patient’s last menstrual period (LMP) was required since she asked if the patient had protected coitus since her LMP and the patient answered yes. The gynecologist thought that if a pregnancy were in utero, Mirena placement would prevent implantation. She believed that she had obtained proper informed consent and that the patient acknowledged receiving and reading the Mirena patient information prior to placement. The gynecologist stated she also provided other birth control options.

The patient’s expert witness testified that the gynecologist fell below the standard of care by not obtaining a pregnancy test prior to IUD insertion.

The gynecologist’s expert witness argued that the patient told the gynecologist that she did not have unprotected coitus. The patient herself withheld information from the gynecologist that she had taken Plan B due to condom breakage. The physician’s attorney also noted that the pelvic exam at time of IUD placement was normal.

What’s the verdict?

The patient has a fairly good case. The gynecologist may not have been sufficiently careful, given all of the facts in this case, to ensure that the patient was not pregnant. An expert is testifying that this fell below the acceptable level of care in the profession. At the same time, the failure of the patient to reveal some information may result in reduced damages through “comparative negligence.” Because there will be several questions of fact for a jury to decide, as well as some emotional elements in this case, the outcome of a trial is uncertain. This suggests that a negotiated settlement before trial should be considered.

Read about medical considerations of a pregnancy with an IUD.

Medical considerations

First, some background information on Mirena.

Indications for Mirena

Here are indications for Mirena¹:

• intrauterine contraception for up to 5 years
• treatment of heavy menstrual bleeding for women who choose to use intrauterine contraception as their method of contraception.

Prior to insertion, the following are recommended²:

• a complete medical and social history should be obtained to determine conditions that might influence the selection of a levonorgestrel-releasing intrauterine system (LNG IUS) for contraception
• if indicated, perform a physical examination, and appropriate tests for any forms of genital or other sexually transmitted infections
• there is no requirement for prepregnancy test.

Contraindications for Mirena

Contraindications for Mirena include²:

• pregnancy or suspicion of pregnancy; cannot be used for postcoital contraception
• congenital or acquired uterine anomaly including fibroids if they distort the uterine cavity
• acute pelvic inflammatory disease or a history of pelvic inflammatory disease unless there has been a subsequent intrauterine pregnancy
• postpartum endometritis or infected abortion in the past 3 months
• known or suspected uterine or cervical neoplasia
• known or suspected breast cancer or other progestin-sensitive cancer, now or in the past
• uterine bleeding of unknown etiology
• untreated acute cervicitis or vaginitis, including bacterial vaginosis or other lower genital tract infections until infection is controlled
• acute liver disease or liver tumor (benign or malignant)
• conditions associated with increased susceptibility to pelvic infections
• a previously inserted IUD that has not been removed
• hypersensitivity to any component of this product.

Is Mirena a postcoital contraceptive?

The American College of Obstetricians and Gynecologists (ACOG) bulletin on long-acting reversible contraception states “the levonorgestrel intrauterine system has not been studied for emergency contraception.”³ Ongoing studies are comparing the levonor‑gestrel IUD to the copper IUD for emergency contraception.⁴

Accuracy of home pregnancy tests

Although the first home pregnancy test was introduced in 1976,⁵ there are now several home pregnancy tests available over the counter, most designed to detect urinary levels of hCG at ≥25 mIU/mL. The tests identify hCG, hyperglycosylated hCG, and free Betasubunit hCG in urine. When Cole and colleagues evaluated the validity of urinary tests including assessment of 18 brands, results noted that sensitivity of 12.4 mIU/mL of hCG detected 95% of pregnancies at time of missed menses.⁶ Some brands required 100 mIU/mL levels of hCG for positive results. The authors concluded “the utility of home pregnancy tests is questioned.”⁶ For urinary levels of hCG, see TABLE.

Pregnancy with an IUD

The gynecologist’s concern about pregnancy when an IUD is inserted was valid.

With regard to pregnancy with Mirena in place, the full prescribing information states²:

Intrauterine Pregnancy: If pregnancy occurs while using Mirena, remove Mirena because leaving it in place may increase the risk of spontaneous abortion and preterm labor. Removal of Mirena or probing of the uterus may also result in spontaneous abortion. In the event of an intrauterine pregnancy with Mirena, consider the following:
Septic abortion
In patients becoming pregnant with an IUD in place, septic abortion - with septicemia, septic shock, and death may occur.
Continuation of pregnancy
If a woman becomes pregnant with Mirena in place and if Mirena cannot be removed or the woman chooses not to have it removed, warn her that failure to remove Mirena increases the risk of miscarriage, sepsis, premature labor and premature delivery. Follow her pregnancy closely and advise her to report immediately any symptom that suggests complications of the pregnancy.

Concern for microbial invasion of the amniotic cavity must be considered. Kim and colleagues addressed pregnancy prognosis with an IUD in situ in a retrospective study of 12,297 pregnancies; 196 had an IUD with singleton gestation.⁷ The study revealed a higher incidence of histologic chorioamnionitis and/or funisitis when compared with those without an IUD (54.2% vs 14.7%, respectively; P<.001). The authors concluded that pregnant women with an IUD in utero are at very high risk for adverse pregnancy outcomes. Brahmi and colleagues⁸ reported similar risks with higher incidence of spontaneous abortion, preterm delivery, and septic abortion.

Efficacy and safety concerns with emergency contraception

The efficacy and safety of emergency contraception using levonorgestrel oral tablets (Plan B One-Step; Duramed Pharmaceuticals) is another concern. Plan B One-Step should be taken orally as soon as possible within 72 hours after unprotected intercourse or a known or suspected contraceptive failure. Efficacy is better if Plan B is taken as soon as possible after unprotected intercourse. There are 2 dosages: 1 tablet of levonorgestrel 1.5 mg or 2 tablets of levonorgestrel 0.75 mg. The second 0.75-mg tablet should be taken 12 hours after the first dose.⁹

Plan B can be used at any time during the menstrual cycle. In a series of 2,445 women aged 15 to 48 years who took levonorgestrel tablets for emergency contraception (Phase IV clinical trial), 5 pregnancies occurred (0.2%).¹⁰

ACOG advises that emergency contraception using a pill or the copper IUD should be initiated as soon as possible (up to 5 days) after unprotected coitus or inadequately protected coitus.⁹

Retained products of contraception

ACOG Practice Bulletin No. 135 on complications associated with second trimesterabortion discusses retained POC.¹¹ The approach to second trimester abortion includes dilation and evacuation (D&E) as well as medical therapy with mifepristone and misoprostol. D&E, a safe and effective approach with advantages over medical abortion, is associated with fewer complications (up to 4%) versus medical abortion (29%); the primary complication is retained POC (placenta).¹¹

Read about the legal considerations of this case.

Legal considerations

The malpractice lawsuit filed in this case claims that the gynecologist failed to exercise the level of care of a reasonably prudent practitioner under the circumstances and was therefore negligent or in breach of a duty to the patient.

First, a lawyer would look for a medical error that was related to some harm. Keep in mind that not all medical errors are negligent or subject to liability. Many medical errors occur even though the physician has exercised all reasonable care and engaged in sound practice, given today’s medical knowledge and facilities. When harm is caused through medical error that was careless or otherwise does not meet the standard of care, financial recovery is possible for the patient through a malpractice claim.¹²

In this case, the expert witnesses’ statements focus on the issue of conducting a pregnancy test prior to IUD insertion. The patient’s expert testified that failure to perform a pregnancy test was below an acceptable standard of care. That opinion may have been based on the typical practice of gynecologists, widely accepted medical text books, and formal practice standards of professional organizations.¹³

Cost-benefit analysis. Additional support for the claim that not performing the pregnancy test is negligent comes from applying a cost-benefit analysis. In this analysis, the risks and costs of performing a pregnancy test are compared with the benefits of doing the test.

In this case, the cost of conducting the pregnancy test is very low: essentially risk-freeand relatively inexpensive. On the other hand, the harm that could be avoided would be significant. Kim and colleagues suggest that pregnant women with an IUD in utero are at very high risk for adverse pregnancy outcomes.⁷ Given that women receiving IUDs are candidates for pregnancy (and perhaps do not know they are pregnant), a simple, risk-free pregnancy test would seem to be an efficient way to avoid a nontrivial harm.¹⁴

Did she have unprotected sex? The gynecologist’s expert notes that the patient told the gynecologist that she did not have unprotected coitus. Furthermore, the patient withheld from the gynecologist the information that she had taken Plan B because of a broken condom. Is this a defense against the malpractice claim? The answer is “possibly no,” or “possibly somewhat.”

As for unprotected coitus, the patient could easily have misunderstood the question. Technically, the answer “no” was correct. She had not had unprotected sex—it is just that the protection (condom) failed. It does not appear from the facts that she disclosed or was asked about Plan B or other information related to possible failed contraception. As to whether the patient’s failure to provide that information could be a defense for the physician, the best answer is “possibly” and “somewhat.” (See below.)¹⁵

Withholding information. Patients, of course, have a responsibility to inform their physicians of information they know is relevant. Many patients, however, will not know what is relevant (or why), or will not be fully disclosing.

Professionals cannot ignore the fact that their patients and clients are often confused, do not understand what is important and relevant, and cannot always be relied upon. For that very reason, professionals generally are obliged to start with the proposition that they may not have all of the relevant information. In this case, this lack of information makes the cost-calculation of performing a pregnancy test that much more important. The risk of not knowing whether a patient is pregnant includes the fact that many patients just will not know or cannot say with assurance.¹⁶

A “somewhat” defense and comparative negligence

Earlier we referred to a “somewhat” defense. Almost all states now have some form of “comparative negligence,” meaning that the patient’s recovery is reduced by the proportion of the blame (negligence) that is attributed to the patient. The most common form of comparative negligence works this way: If there are damages of $100,000, and the jury finds that the fault is 20% the patient’s and 80% the physician’s, the patient would receive $80,000 recovery. (In the past, the concept of “contributory negligence” could result in the plaintiff being precluded from any recovery if the plaintiff was partially negligent—those days are mostly gone.)

Informed consent: The more you know, the more you and your patient are protected

Statement of risks, informed consent, and liability

The gynecologist must provide an adequate description of the IUD risks. The case facts indicate that appropriate risks were discussed and literature provided, so it appears there was probably appropriate informed consent in this case. If not true, this would provide another basis for recovery.

Two other aspects of this case could be the basis for liability. We can assume that the attempted removal of the IUD was performed competently.¹⁶ In addition, if the IUD was defective in terms of design, manufacture, or warnings, the manufacturer of the device could be subject to liability.¹⁷

Read about the final verdict.

Final verdict: Out of court settlement

Why would the gynecologist and the insurance company settle this case? After all, they have some arguments on their side, and physicians win the majority of malpractice cases that go to trial.¹⁸ On the other hand, the patient’s expert witness’ testimony and the cost-benefit analysis of the pregnancy test are strong, contrary claims.

Cases are settled for a variety of reasons. Litigation is inherently risky. In this case, we assume that the court denied a motion to dismiss the case before trial because there is a legitimate question of fact concerning what a reasonably prudent gynecologist would have done under the circumstances. That means a jury would probably decide the issue of medical judgment, which is generally disconcerting. Furthermore, the comparative negligence defense that the patient did not tell the gynecologist about the failed condom/Plan B would most likely reduce the amount of damages, but not eliminate liability. The questions regarding the pressure to terminate a second trimester pregnancy might well complicate a jury’s view.

Other considerations include the high costs in time, money, uncertainty, and disruption associated with litigation. The settlement amount was not stated, but the process of negotiating a settlement would allow factoring in the comparative negligence aspect of the case. It would be reasonable for this case to settle before trial.

Should the physician have apologized before trial? The gynecologist could have sent a statement of regret or apology to the patient before a lawsuit was filed. Most states now have statutes that preclude such statements of regret or apology from being used against the physician. Many experts now favor apology statements as a way to reduce the risk of malpractice suits being filed.¹⁹

Defensive medicine. There has been much discussion of “defensive medicine” in recent years.²⁰ It is appropriately criticized when additional testing is solely used to protect the physician from liability. However, much of defensive medicine is not only to protect the physician but also to protect the patient from potential physical and mental harm. In this case, it would have been “careful medicine” in addition to “defensive medicine.”

CASE: Gynecologist accused of placing an IUD without performing a pregnancy test

A 34-year-old woman (G4 P3013) presents to her gynecologist for planned placement of the Mirena Intrauterine System (Bayer HealthCare). She was divorced 2 months ago and is interested in birth control. She smokes 1.5 packs per day, and her history includes irregular menses, an earlier Pap smear result of atypical squamous cells of undetermined significance (ASCUS) with negative colposcopy results, polycystic ovary syndrome, obesity, migraine headaches with aura, bilateral carpel tunnel surgery, and a herniated L4.5 disc treated conservatively. She has no history of any psychiatric problems.

One week before intrauterine device (IUD) placement, she discussed the options with her gynecologist and received a Mirena patient brochure. At the office visit for IUD placement, the patient stated she had a negative home pregnancy test 1 week earlier. She did not tell the gynecologist that she had taken Plan B One-Step (levonorgestrel, 1.5 mg) emergency contraception 2 weeks prior to presenting to her gynecologist after receiving it from a Planned Parenthood office following condom breakage during coitus. IUD placement was uncomplicated.

After noting spotting several weeks later, she contacted her gynecologist’s office. Results of an office urine pregnancy test were positive; the serum human chorionic gonadotropin (hCG) level was reported at 65,000 mIU/mL.The results of a pelvic sonogram showed a 12 5/7-week intrauterine gestation. The gynecologist unsuccessfully tried to remove the IUD. Options for termination or continuation of the pregnancy were discussed. The patient felt the gynecologist strongly encouraged, “almost insisting on,” termination. Termination could not be performed locally as her state laws did not allow second trimester abortion; the gynecologist provided out-of-state clinic options.

The patient aborted the pregnancy in a neighboring state. She was opposed to the termination but decided it was not a good time for her to have a baby. She felt the staff at the facility were “cold” and had a “we got to get this done attitude.” As she left the clinic, she saw people picketing outside and found the whole process “psychologically traumatic.” When bleeding persisted, she sought care from another gynecologist. Pelvic sonography results showed retained products of conception (POC). The new gynecologist performed operative hysteroscopy to remove the POC. The patient became depressed and felt as if she was a victim of pain and suffering.

The patient’s attorney filed a medical malpractice claim against the gynecologist who inserted the IUD, accusing her of negligence for not performing a pregnancy test immediately before IUD insertion.

In a deposition, the patient stated she bought the home pregnancy test in a “dollar store” and was worried about its accuracy, but never told the gynecologist. Conception probably occurred 2 weeks prior to IUD insertion, correlating with the broken condom and taking of Plan B. She did not think the gynecologist needed to know this as it “would not have made any difference in her care.”

The gynecologist confirmed that the patient’s record included “Patient stated ‘pregnancy test negative within 1 week of IUD placement.’” The gynecologist did not feel that obtaining the date of the patient’s last menstrual period (LMP) was required since she asked if the patient had protected coitus since her LMP and the patient answered yes. The gynecologist thought that if a pregnancy were in utero, Mirena placement would prevent implantation. She believed that she had obtained proper informed consent and that the patient acknowledged receiving and reading the Mirena patient information prior to placement. The gynecologist stated she also provided other birth control options.

The patient’s expert witness testified that the gynecologist fell below the standard of care by not obtaining a pregnancy test prior to IUD insertion.

The gynecologist’s expert witness argued that the patient told the gynecologist that she did not have unprotected coitus. The patient herself withheld information from the gynecologist that she had taken Plan B due to condom breakage. The physician’s attorney also noted that the pelvic exam at time of IUD placement was normal.

What’s the verdict?

The patient has a fairly good case. The gynecologist may not have been sufficiently careful, given all of the facts in this case, to ensure that the patient was not pregnant. An expert is testifying that this fell below the acceptable level of care in the profession. At the same time, the failure of the patient to reveal some information may result in reduced damages through “comparative negligence.” Because there will be several questions of fact for a jury to decide, as well as some emotional elements in this case, the outcome of a trial is uncertain. This suggests that a negotiated settlement before trial should be considered.

Read about medical considerations of a pregnancy with an IUD.

Medical considerations

First, some background information on Mirena.

Indications for Mirena

Here are indications for Mirena¹:

• intrauterine contraception for up to 5 years
• treatment of heavy menstrual bleeding for women who choose to use intrauterine contraception as their method of contraception.

Prior to insertion, the following are recommended²:

• a complete medical and social history should be obtained to determine conditions that might influence the selection of a levonorgestrel-releasing intrauterine system (LNG IUS) for contraception
• if indicated, perform a physical examination, and appropriate tests for any forms of genital or other sexually transmitted infections
• there is no requirement for prepregnancy test.

Contraindications for Mirena

Contraindications for Mirena include²:

• pregnancy or suspicion of pregnancy; cannot be used for postcoital contraception
• congenital or acquired uterine anomaly including fibroids if they distort the uterine cavity
• acute pelvic inflammatory disease or a history of pelvic inflammatory disease unless there has been a subsequent intrauterine pregnancy
• postpartum endometritis or infected abortion in the past 3 months
• known or suspected uterine or cervical neoplasia
• known or suspected breast cancer or other progestin-sensitive cancer, now or in the past
• uterine bleeding of unknown etiology
• untreated acute cervicitis or vaginitis, including bacterial vaginosis or other lower genital tract infections until infection is controlled
• acute liver disease or liver tumor (benign or malignant)
• conditions associated with increased susceptibility to pelvic infections
• a previously inserted IUD that has not been removed
• hypersensitivity to any component of this product.

Is Mirena a postcoital contraceptive?

The American College of Obstetricians and Gynecologists (ACOG) bulletin on long-acting reversible contraception states “the levonorgestrel intrauterine system has not been studied for emergency contraception.”³ Ongoing studies are comparing the levonor‑gestrel IUD to the copper IUD for emergency contraception.⁴

Accuracy of home pregnancy tests

Although the first home pregnancy test was introduced in 1976,⁵ there are now several home pregnancy tests available over the counter, most designed to detect urinary levels of hCG at ≥25 mIU/mL. The tests identify hCG, hyperglycosylated hCG, and free Betasubunit hCG in urine. When Cole and colleagues evaluated the validity of urinary tests including assessment of 18 brands, results noted that sensitivity of 12.4 mIU/mL of hCG detected 95% of pregnancies at time of missed menses.⁶ Some brands required 100 mIU/mL levels of hCG for positive results. The authors concluded “the utility of home pregnancy tests is questioned.”⁶ For urinary levels of hCG, see TABLE.

Pregnancy with an IUD

The gynecologist’s concern about pregnancy when an IUD is inserted was valid.

With regard to pregnancy with Mirena in place, the full prescribing information states²:

Intrauterine Pregnancy: If pregnancy occurs while using Mirena, remove Mirena because leaving it in place may increase the risk of spontaneous abortion and preterm labor. Removal of Mirena or probing of the uterus may also result in spontaneous abortion. In the event of an intrauterine pregnancy with Mirena, consider the following:
Septic abortion
In patients becoming pregnant with an IUD in place, septic abortion - with septicemia, septic shock, and death may occur.
Continuation of pregnancy
If a woman becomes pregnant with Mirena in place and if Mirena cannot be removed or the woman chooses not to have it removed, warn her that failure to remove Mirena increases the risk of miscarriage, sepsis, premature labor and premature delivery. Follow her pregnancy closely and advise her to report immediately any symptom that suggests complications of the pregnancy.

Concern for microbial invasion of the amniotic cavity must be considered. Kim and colleagues addressed pregnancy prognosis with an IUD in situ in a retrospective study of 12,297 pregnancies; 196 had an IUD with singleton gestation.⁷ The study revealed a higher incidence of histologic chorioamnionitis and/or funisitis when compared with those without an IUD (54.2% vs 14.7%, respectively; P<.001). The authors concluded that pregnant women with an IUD in utero are at very high risk for adverse pregnancy outcomes. Brahmi and colleagues⁸ reported similar risks with higher incidence of spontaneous abortion, preterm delivery, and septic abortion.

Efficacy and safety concerns with emergency contraception

The efficacy and safety of emergency contraception using levonorgestrel oral tablets (Plan B One-Step; Duramed Pharmaceuticals) is another concern. Plan B One-Step should be taken orally as soon as possible within 72 hours after unprotected intercourse or a known or suspected contraceptive failure. Efficacy is better if Plan B is taken as soon as possible after unprotected intercourse. There are 2 dosages: 1 tablet of levonorgestrel 1.5 mg or 2 tablets of levonorgestrel 0.75 mg. The second 0.75-mg tablet should be taken 12 hours after the first dose.⁹

Plan B can be used at any time during the menstrual cycle. In a series of 2,445 women aged 15 to 48 years who took levonorgestrel tablets for emergency contraception (Phase IV clinical trial), 5 pregnancies occurred (0.2%).¹⁰

ACOG advises that emergency contraception using a pill or the copper IUD should be initiated as soon as possible (up to 5 days) after unprotected coitus or inadequately protected coitus.⁹

Retained products of contraception

ACOG Practice Bulletin No. 135 on complications associated with second trimesterabortion discusses retained POC.¹¹ The approach to second trimester abortion includes dilation and evacuation (D&E) as well as medical therapy with mifepristone and misoprostol. D&E, a safe and effective approach with advantages over medical abortion, is associated with fewer complications (up to 4%) versus medical abortion (29%); the primary complication is retained POC (placenta).¹¹

Read about the legal considerations of this case.

Legal considerations

The malpractice lawsuit filed in this case claims that the gynecologist failed to exercise the level of care of a reasonably prudent practitioner under the circumstances and was therefore negligent or in breach of a duty to the patient.

First, a lawyer would look for a medical error that was related to some harm. Keep in mind that not all medical errors are negligent or subject to liability. Many medical errors occur even though the physician has exercised all reasonable care and engaged in sound practice, given today’s medical knowledge and facilities. When harm is caused through medical error that was careless or otherwise does not meet the standard of care, financial recovery is possible for the patient through a malpractice claim.¹²

In this case, the expert witnesses’ statements focus on the issue of conducting a pregnancy test prior to IUD insertion. The patient’s expert testified that failure to perform a pregnancy test was below an acceptable standard of care. That opinion may have been based on the typical practice of gynecologists, widely accepted medical text books, and formal practice standards of professional organizations.¹³

That opinion may have been based on the typical practice of gynecologists, widely accepted medical text books, and formal practice standards of professional organizations.¹³

Cost-benefit analysis. Additional support for the claim that not performing the pregnancy test is negligent comes from applying a cost-benefit analysis. In this analysis, the risks and costs of performing a pregnancy test are compared with the benefits of doing the test.

In this case, the cost of conducting the pregnancy test is very low: essentially risk-freeand relatively inexpensive. On the other hand, the harm that could be avoided would be significant. Kim and colleagues suggest that pregnant women with an IUD in utero are at very high risk for adverse pregnancy outcomes.⁷ Given that women receiving IUDs are candidates for pregnancy (and perhaps do not know they are pregnant), a simple, risk-free pregnancy test would seem to be an efficient way to avoid a nontrivial harm.¹⁴

Did she have unprotected sex? The gynecologist’s expert notes that the patient told the gynecologist that she did not have unprotected coitus. Furthermore, the patient withheld from the gynecologist the information that she had taken Plan B because of a broken condom. Is this a defense against the malpractice claim? The answer is “possibly no,” or “possibly somewhat.”

As for unprotected coitus, the patient could easily have misunderstood the question. Technically, the answer “no” was correct. She had not had unprotected sex—it is just that the protection (condom) failed. It does not appear from the facts that she disclosed or was asked about Plan B or other information related to possible failed contraception. As to whether the patient’s failure to provide that information could be a defense for the physician, the best answer is “possibly” and “somewhat.” (See below.)¹⁵

Withholding information. Patients, of course, have a responsibility to inform their physicians of information they know is relevant. Many patients, however, will not know what is relevant (or why), or will not be fully disclosing.

Professionals cannot ignore the fact that their patients and clients are often confused, do not understand what is important and relevant, and cannot always be relied upon. For that very reason, professionals generally are obliged to start with the proposition that they may not have all of the relevant information. In this case, this lack of information makes the cost-calculation of performing a pregnancy test that much more important. The risk of not knowing whether a patient is pregnant includes the fact that many patients just will not know or cannot say with assurance.¹⁶

A “somewhat” defense and comparative negligence

Earlier we referred to a “somewhat” defense. Almost all states now have some form of “comparative negligence,” meaning that the patient’s recovery is reduced by the proportion of the blame (negligence) that is attributed to the patient. The most common form of comparative negligence works this way: If there are damages of $100,000, and the jury finds that the fault is 20% the patient’s and 80% the physician’s, the patient would receive $80,000 recovery. (In the past, the concept of “contributory negligence” could result in the plaintiff being precluded from any recovery if the plaintiff was partially negligent—those days are mostly gone.)

Informed consent: The more you know, the more you and your patient are protected

Statement of risks, informed consent, and liability

The gynecologist must provide an adequate description of the IUD risks. The case facts indicate that appropriate risks were discussed and literature provided, so it appears there was probably appropriate informed consent in this case. If not true, this would provide another basis for recovery.

Two other aspects of this case could be the basis for liability. We can assume that the attempted removal of the IUD was performed competently.¹⁶ In addition, if the IUD was defective in terms of design, manufacture, or warnings, the manufacturer of the device could be subject to liability.¹⁷

Read about the final verdict.

Final verdict: Out of court settlement

Why would the gynecologist and the insurance company settle this case? After all, they have some arguments on their side, and physicians win the majority of malpractice cases that go to trial.¹⁸ On the other hand, the patient’s expert witness’ testimony and the cost-benefit analysis of the pregnancy test are strong, contrary claims.

Cases are settled for a variety of reasons. Litigation is inherently risky. In this case, we assume that the court denied a motion to dismiss the case before trial because there is a legitimate question of fact concerning what a reasonably prudent gynecologist would have done under the circumstances. That means a jury would probably decide the issue of medical judgment, which is generally disconcerting. Furthermore, the comparative negligence defense that the patient did not tell the gynecologist about the failed condom/Plan B would most likely reduce the amount of damages, but not eliminate liability. The questions regarding the pressure to terminate a second trimester pregnancy might well complicate a jury’s view.

Other considerations include the high costs in time, money, uncertainty, and disruption associated with litigation. The settlement amount was not stated, but the process of negotiating a settlement would allow factoring in the comparative negligence aspect of the case. It would be reasonable for this case to settle before trial.

Should the physician have apologized before trial? The gynecologist could have sent a statement of regret or apology to the patient before a lawsuit was filed. Most states now have statutes that preclude such statements of regret or apology from being used against the physician. Many experts now favor apology statements as a way to reduce the risk of malpractice suits being filed.¹⁹

Medical errors: Meeting ethical obligations and reducing liability with proper communication

Defensive medicine. There has been much discussion of “defensive medicine” in recent years.²⁰ It is appropriately criticized when additional testing is solely used to protect the physician from liability. However, much of defensive medicine is not only to protect the physician but also to protect the patient from potential physical and mental harm. In this case, it would have been “careful medicine” in addition to “defensive medicine.”

“TREATING POLYCYSTIC OVARY SYNDROME: START USING DUAL MEDICAL THERAPY”

ROBERT L. BARBIERI, MD (EDITORIAL; APRIL 2017)

Weight loss and dietary management for PCOS

I enjoyed Dr. Barbieri’s editorial on polycystic ovary syndrome (PCOS), but I feel that first-line management for PCOS should be weight loss and diet modifications that include instructions on decreasing carbohydrates and insulin spikes. A 5% to 10% weight loss should produce a return of cycles. Of course, metformin and spironolactone have a place for added treatment/prevention of acne and diabetes.

Metformin and progesterone for PCOS-related infertility

I have been using Beyaz and Yaz for several years in my PCOS patients for the lower androgenic activity of the drospirenone based on the same assumption and its similarity to spironolactone. I have gotten great results with metformin 1,500 mg daily and, for those who desire fertility, cycling once a month for 10 days with progesterone. My own daughter was able to conceive in just 3 months of therapy. PCOS is extremely common in our region, probably due to the high obesity rate. I saw many more cases here than I ever thought I would when I was training.

Check insulin levels in PCOS patients before giving metformin?

Thank you for the very nice article regarding PCOS treatment. Does Dr. Barbieri routinely check insulin levels on patients before treating with metformin and does he require abnormal insulin levels to be present before initiating treatment? The article suggested that using the listed risk factors is sufficient. Additionally, does he perform glucose-insulin testing? If so, what is the protocol used? I have used fasting levels and 2-hour post 75-g glucose-drink testing as well. What is the best approach?

Contraception and spironolactone

As usual, Dr. Barbieri has provided a thorough, concise, and practical overview on the medical management of PCOS. I would add just one small point. Another reason for using an oral estrogen-progestin pill concomitantly with spironolactone is due to the potential teratogenicity of this medication.

Low-carb diet helps mitigate metformin side effects

Thank you for the article on PCOS. I have been treating PCOS this way for about 15 years and have been following lipids and seen dramatic improvements with that as well. I wish we as a medical community would focus on the low carbohydrate diet to help avert metformin side effects as well as treat the metabolic issues. You can get many people back on metformin by just adjusting their diet. I hope you can spread this word.

Dr. Barbieri responds

I thank Dr. Linan, Dr. Foley, and Ms. Gowan for sharing their important insights with our readers. I agree with Dr. Linan that I should have highlighted the important guidance that women with PCOS and a body mass index (BMI) above the normal range should be encouraged to reduce their weight by 5% to 10% with diet and exercise. Dr. Foley offers a clinical pearl that a low carbohydrate diet will reduce the gastrointestinal symptoms that may occur with metformin therapy. Ms. Gowan notes that the combination of metformin plus cyclic progesterone may help to initiate more frequent ovulatory cycles in women with PCOS, thereby improving fertility. Dr. Hecht reminds us that spironolactone is a teratogen and using effective contraception can help reduce the risk of exposing a pregnancy to the medication.

Dr. Beckman raises the important clinical issue of whether it is helpful to measure insulin concentration. Measuring insulin and glucose is especially helpful in understanding the causes of hypoglycemia. An elevated insulin level at the time of an abnormally low glucose level is very worrisome. However, for women with PCOS, in whom insulin resistance is common, measuring insulin is of minimal clinical value. A normal or elevated insulin level is consistent with the diagnosis of PCOS. Assessing BMI, waist circumference, HDL-cholesterol, fasting triglyceride level, and blood pressure— components of the metabolic syndrome—are much more useful clinically. The dermatologic skin lesion acanthosis nigricans is also a sign consistent with insulin resistance. I do not measure insulin levels in my patients with PCOS. Metformin is a useful agent in the treatment of PCOS whether or not insulin resistance is present. Metformin may have direct actions on the ovary to reduce androgen production, in addition to its beneficial effects in the liver.

Transvaginal ultrasound (TVU) cervical length (CL) screening for prediction and prevention of spontaneous preterm birth (SPTB) is among the most transformative clinical changes in obstetrics in the last decades. TVU CL screening should now be offered to all pregnant women: hence the appellative ‘universal CL screening.’

TVU CL screening is an excellent screening test for several reasons. It screens for SPTB, which is a clinically important, well-defined disease whose prevalence and natural history is known, and has an early recognizable asymptomatic phase in CL shortening detected by TVU. TVU CL screening is a well-described technique, safe and acceptable, with a reasonable cutoff (25 mm) now identified for all populations, and results are reproducible and accurate. There are hundreds of studies proving these facts. In the last 10 years, TVU measurement of CL as a screening test has been accepted^1,2: it identifies women at risk for SPTB, and an early intervention (progesterone or cerclage depending on the clinical situation) is effective in preventing SPTB. Screening and treatment of short cervix is cost-effective and readily available as an early intervention (progesterone or cerclage depending on the clinical situation), is effective in preventing the outcome (SPTB), treating abnormal results is cost-effective, and facilities for screening are available and treatments are readily available.^3–5 It is also important to emphasize that CL screening for prevention of SPTB should be done by TVU, and not by transabdominal ultrasound.⁶It is best to review TVU CL screening by populations: singletons without prior SPTB, singletons with prior SPTB, and twins (Table).

Related Article:
Can transabdominal ultrasound exclude short cervix?

Singletons without prior SPTB

Women with no previous SPTB who are carrying a singleton pregnancy is the population in which TVU CL could have the greatest impact on decreasing SPTB, for several reasons:

1. Up to 60% to 90% of SPTB occur in this population.
2. More than 90% of these women have risk factors for SPTB.^7,8
3. Vaginal progesterone has been associated with a significant 39% decrease in PTB at <33 weeks of gestation and a significant 38% decrease in perinatal morbidity and mortality in a meta-analysis of randomized controlled trials (RCTs) including 606 women without prior PTB.^9,10
4. Cost-effectiveness studies have shown that TVU CL screening in this specific population prevents thousands of preterm births, saves or improves from death or major morbidity 350 babies’ lives annually, and saves approximately $320,000 per year in the US alone.³ These numbers may be even higher now as the TVU CL cutoff for offering vaginal progesterone has moved in many centers from ≤20 mm to ≤25 mm, including more women (from about 0.8% to about 2% to 3%, respectively¹¹) who benefit from screening.
5. Real-world implementation studies have indeed shown significant decreases in SPTB when a policy of universal TVU CL screening in this specific population is implemented.^12,13

Universal TVU CL screening recently called into question

In a recent article published in the Journal of the American Medical Association,¹⁴ TVU CL screening in this population, in particular for nulliparous women, has come under interrogation. The authors found only an 8% sensitivity of TVU CL screening for SPTB using a cutoff of ≤25 mm at 16 0/7 to 22 6/7 weeks of gestation in 9,410 nulliparous women. This result is different compared with other previous cohort studies in this area, however, and is likely related to a number of issues in the methodology.

First, TVU CL screening was done in many women at too early a gestational age. The earlier the CL screening, the lower the sensitivity of the procedure. Data at 16 and 17 weeks of gestation should have been excluded, as almost all RCTs and other studies on universal TVU CL screening in this population recommended doing screening at about 18 0/7 to 23 6/7 weeks.

Second, women with TVU CL <15 mm received vaginal progesterone. This would decrease the incidence of PTB and, therefore, sensitivity.

Third, outcomes data were not available for 469 women and, compared with women analyzed, these women were at higher risk for SPTB as they were more likely to be aged 21 years or younger, black, with less than a high school education, and single, all significant risk factors for SPTB. (Not all risk factors for SPTB were reported in this study.)

Fourth, pregnancy losses before 20 weeks were excluded, and these could have been early SPTB; therefore, the sensitivity could have been decreased if women with this outcome were excluded.

Fifth, prior studies have shown that TVU CL screening in singletons without prior SPTB has a sensitivity of about 30% to 40%.^15,16 In nulliparas, the sensitivity of TVU CL ≤20 mm had been reported previously to be 20%.¹⁶ Additional data from 2012–2014 at our institution demonstrate that the incidence of CL ≤25 mm is about 2.8% in nulliparous women, with a sensitivity of 19.5% for SPTB <37 weeks. These numbers show again that 8% sensitivity was low in the JAMA study¹⁴ due the shortcomings we just highlighted. Furthermore, the reported sensitivity of TVU CL ≤25 mm for PTB <32 weeks was 24% in Esplin and colleagues’ study,¹⁴ while 60% in our data. Given that early preterm births are the most significant source of neonatal morbidity and mortality, women with a singleton gestation and no prior SPTB but with a short TVU CL are perhaps the most important subgroup to identify.

Sixth, a low sensitivity in and of itself is not reflective of a poor screening test. We have known for a long time that SPTB has many etiologies. No one screening test, and no one intervention, would independently prevent all SPTBs. In a population that accounts for more than half of PTBs and for whom no other screening test has been found to be effective, much less cost effective, it is important not to cast aside the dramatic potential clinical benefit to TVU CL screening.

A stepwise approach to cervical cerclage

Singletons with a prior SPTB

This is the first population in which TVU CL screening was first proven beneficial for prevention of SPTB. These women all should receive progesterone starting at 16 weeks because of the prior SPTB. In these women, TVU CL screening should be initiated at 16 weeks, and repeated every 2 weeks (weekly if TVU CL is found to be 25 mm to 29 mm) until 23 6/7 weeks. If the TVU CL is identified to be <25 mm before 24 weeks, cerclage should be recommended.^1,2,17

Twins

Twins are the most recent population in which an intervention based on TVU CL screening has been shown to be beneficial. Vaginal progesterone has been associated with a significant decrease in SPTB as well as in some neonatal outcomes in twin gestations found to have a TVU CL <25 mm in the midtrimester in a meta-analysis of RCTs.¹⁸ Based on these results, we at our institution recently have started offering TVU CL screening at the time of the anatomy scan (about 20 weeks) to twin gestations.

Bottom line

In summary, universal second trimester TVU CL screening of both singletons and twin gestations should be considered seriously by obstetric practitioners to successfully decrease the grave burden of SPTB.

Singletons with a prior SPTB

This is the first population in which TVU CL screening was first proven beneficial for prevention of SPTB. These women all should receive progesterone starting at 16 weeks because of the prior SPTB. In these women, TVU CL screening should be initiated at 16 weeks, and repeated every 2 weeks (weekly if TVU CL is found to be 25 mm to 29 mm) until 23 6/7 weeks. If the TVU CL is identified to be <25 mm before 24 weeks, cerclage should be recommended.^1,2,17

Twins

Twins are the most recent population in which an intervention based on TVU CL screening has been shown to be beneficial. Vaginal progesterone has been associated with a significant decrease in SPTB as well as in some neonatal outcomes in twin gestations found to have a TVU CL <25 mm in the midtrimester in a meta-analysis of RCTs.¹⁸ Based on these results, we at our institution recently have started offering TVU CL screening at the time of the anatomy scan (about 20 weeks) to twin gestations.

Transvaginal ultrasound (TVU) cervical length (CL) screening for prediction and prevention of spontaneous preterm birth (SPTB) is among the most transformative clinical changes in obstetrics in the last decades. TVU CL screening should now be offered to all pregnant women: hence the appellative ‘universal CL screening.’

TVU CL screening is an excellent screening test for several reasons. It screens for SPTB, which is a clinically important, well-defined disease whose prevalence and natural history is known, and has an early recognizable asymptomatic phase in CL shortening detected by TVU. TVU CL screening is a well-described technique, safe and acceptable, with a reasonable cutoff (25 mm) now identified for all populations, and results are reproducible and accurate. There are hundreds of studies proving these facts. In the last 10 years, TVU measurement of CL as a screening test has been accepted^1,2: it identifies women at risk for SPTB, and an early intervention (progesterone or cerclage depending on the clinical situation) is effective in preventing SPTB. Screening and treatment of short cervix is cost-effective and readily available as an early intervention (progesterone or cerclage depending on the clinical situation), is effective in preventing the outcome (SPTB), treating abnormal results is cost-effective, and facilities for screening are available and treatments are readily available.^3–5 It is also important to emphasize that CL screening for prevention of SPTB should be done by TVU, and not by transabdominal ultrasound.⁶It is best to review TVU CL screening by populations: singletons without prior SPTB, singletons with prior SPTB, and twins (Table).

Singletons without prior SPTB

Women with no previous SPTB who are carrying a singleton pregnancy is the population in which TVU CL could have the greatest impact on decreasing SPTB, for several reasons:

1. Up to 60% to 90% of SPTB occur in this population.
2. More than 90% of these women have risk factors for SPTB.^7,8
3. Vaginal progesterone has been associated with a significant 39% decrease in PTB at <33 weeks of gestation and a significant 38% decrease in perinatal morbidity and mortality in a meta-analysis of randomized controlled trials (RCTs) including 606 women without prior PTB.^9,10
4. Cost-effectiveness studies have shown that TVU CL screening in this specific population prevents thousands of preterm births, saves or improves from death or major morbidity 350 babies’ lives annually, and saves approximately $320,000 per year in the US alone.³ These numbers may be even higher now as the TVU CL cutoff for offering vaginal progesterone has moved in many centers from ≤20 mm to ≤25 mm, including more women (from about 0.8% to about 2% to 3%, respectively¹¹) who benefit from screening.
5. Real-world implementation studies have indeed shown significant decreases in SPTB when a policy of universal TVU CL screening in this specific population is implemented.^12,13

Universal TVU CL screening recently called into question

In a recent article published in the Journal of the American Medical Association,¹⁴ TVU CL screening in this population, in particular for nulliparous women, has come under interrogation. The authors found only an 8% sensitivity of TVU CL screening for SPTB using a cutoff of ≤25 mm at 16 0/7 to 22 6/7 weeks of gestation in 9,410 nulliparous women. This result is different compared with other previous cohort studies in this area, however, and is likely related to a number of issues in the methodology.

First, TVU CL screening was done in many women at too early a gestational age. The earlier the CL screening, the lower the sensitivity of the procedure. Data at 16 and 17 weeks of gestation should have been excluded, as almost all RCTs and other studies on universal TVU CL screening in this population recommended doing screening at about 18 0/7 to 23 6/7 weeks.

Second, women with TVU CL <15 mm received vaginal progesterone. This would decrease the incidence of PTB and, therefore, sensitivity.

Third, outcomes data were not available for 469 women and, compared with women analyzed, these women were at higher risk for SPTB as they were more likely to be aged 21 years or younger, black, with less than a high school education, and single, all significant risk factors for SPTB. (Not all risk factors for SPTB were reported in this study.)

Fourth, pregnancy losses before 20 weeks were excluded, and these could have been early SPTB; therefore, the sensitivity could have been decreased if women with this outcome were excluded.

Fifth, prior studies have shown that TVU CL screening in singletons without prior SPTB has a sensitivity of about 30% to 40%.^15,16 In nulliparas, the sensitivity of TVU CL ≤20 mm had been reported previously to be 20%.¹⁶ Additional data from 2012–2014 at our institution demonstrate that the incidence of CL ≤25 mm is about 2.8% in nulliparous women, with a sensitivity of 19.5% for SPTB <37 weeks. These numbers show again that 8% sensitivity was low in the JAMA study¹⁴ due the shortcomings we just highlighted. Furthermore, the reported sensitivity of TVU CL ≤25 mm for PTB <32 weeks was 24% in Esplin and colleagues’ study,¹⁴ while 60% in our data. Given that early preterm births are the most significant source of neonatal morbidity and mortality, women with a singleton gestation and no prior SPTB but with a short TVU CL are perhaps the most important subgroup to identify.

Sixth, a low sensitivity in and of itself is not reflective of a poor screening test. We have known for a long time that SPTB has many etiologies. No one screening test, and no one intervention, would independently prevent all SPTBs. In a population that accounts for more than half of PTBs and for whom no other screening test has been found to be effective, much less cost effective, it is important not to cast aside the dramatic potential clinical benefit to TVU CL screening.

A) Retained products of conception (RPOC) INCORRECT
RPOC is a common complication arising from the presence of retained placental or fetal tissue after delivery, spontaneous, or elective abortion and is diagnosed by the presence of chorionic villi suggesting trophoblastic or placental tissue.^1,2 Interpreting imaging findings is often a challenge secondary to the nonspecific findings of RPOC and often overlapping imaging features with blood products and enhanced myometrial vascularity (EMV) also known as arteriovenous malformation (AVM). Management usually is based on clinical findings in collaboration with supportive imaging features. On ultrasound, RPOC is suspected when there is a thickened endometrial echo complex (>8 mm to 13 mm) and/or the presence of an endometrial mass. Additionally, increased vascularity on color Doppler significantly increases the likelihood of RPOC; the absence of vascularity can be seen with both blood products and avascular RPOC.¹ Vascularity in RPOC can be differentiated from EMV by its extension into the endometrium.

B) Complete hydatidiform mole INCORRECT
Complete hydatidiform mole (CHM) usually presents early in gestation with markedly elevated β-hCG. On ultrasound, it appears classically as an echogenic mass with innumerable small cystic spaces creating a “snowstorm or cluster of grape appearance” from hydropic chorionic villi along with larger irregular fluid collections and the absence of fetal parts.³ Ovarian hyperstimulation from elevated β-hCG can result in large bilateral ovarian cysts called theca lutein cysts.³

C) Enhanced myometrial vascularity (EMV) also known as arteriovenous malformation (AVM). CORRECT
EMV is an extremely rare cause of postpregnancy hemorrhage most often seen secondary to iatrogenic causes but can also be congenital or acquired from excessive hormone stimulation.² On ultrasound, EMV appears as a hypoechoic vascular lesion or serpiginous network of vessels located in the myometrium with increased velocity and low resistance waveform on spectral Doppler.⁴ Subinvolution of placental site implantation where there is failure of the vessels to involute can sometimes be indistinguishable from acquired EMV and occasionally difficult to differentiate from RPOC.¹ In stable patients with equivocal ultrasound findings, magnetic resonance imaging (MRI) with its superior contrast resolution can help delineate the endometrium from myometrium and clearly identify EMV as serpiginous signal voids in the myometrium with avid enhancement following contrast.⁵ Computed tomography (CT) angiogram is also of value in both the diagnosis and pretreatment planning of EMV prior to transcatheter uterine artery embolization.

D) Endometritis INCORRECT
Endometritis is a common cause of fever and sepsis in the postpartum state, but it can also occur after procedures such as uterine fibroid embolization (UFE). On ultrasound, the endometrium usually is distended with avascular echogenic fluid. The presence of shadowing gas in the appropriate clinical setting is concerning for endometritis. CT scan can confirm the presence of gas and evaluate for septic thrombophlebitis, an uncommon, life-threatening complication of endometritis.

"IT IS TIME FOR HPV VACCINATION TO BE CONSIDERED PART OF ROUTINE PREVENTIVE HEALTH CARE"

BARBARA S. LEVY, MD (MARCH 2017)

Nurse practitioner urges advocacy for HPV vaccination

I could not agree more with Dr. Levy's view on human papillomavirus (HPV) vaccination. I am a Doctor of Nursing Practice student and improving HPV vaccination rates in adolescents is the focus of my research project for the next year. Based on the current literature, the most significant factors for increasing vaccination rates are patient education and provider recommendation. As the article mentions, "special" attention should not be given to the HPV vaccine, because this raises questions with families presenting to the office for routine well-child care. There have been many missed opportunities for vaccination of our young people over the past 10 years. As a result, we will continue to see increases in HPV-related cancers. We have a vaccine that has the potential to significantly decrease these cases, but it is underutilized. The recent recommendation of a 2-dose series (before the age of 15) should make completing the series easier. I urge all providers to be better advocates for their patients and make appropriate changes to their current practice in order to reduce the significant burden this disease carries.

"SHOULD YOU ADOPT THE PRACTICE OF VAGINAL CLEANSING WITH POVIDONE-IODINE PRIOR TO CESAREAN DELIVERY?"

ROBERT L. BARBIERI, MD (EDITORIAL; JANUARY 2016)

"PREVENTING INFECTION AFTER CESAREAN DELIVERY: 5 MORE EVIDENCE-BASED MEASURES TO CONSIDER"

KATHRYN E. PATRICK, MD; SARA L. DEATSMAN, MD; AND PATRICK DUFF, MD (DECEMBER 2016)

Prepping the vagina before cesarean delivery

I enjoyed your review of the topic. I am interested in using vaginal preparation prior to cesarean in the settings of active-phase and second-stage arrest. This should be most valuable since we anticipate possible prolonged attempt at head delivery. There may be a need for head elevation as well. Of course, we have become enthusiastic about using reverse breech extraction in difficult cases since your article a few years ago. I have yet to do a Patwardhan maneuver. That seems to rely on rotating the spine anteriorly to get the second arm out. With the head impaction, there is limited range for neck rotation. With vaginal preparation, is there any concern about fetal exposure to iodine?  

Kimberly Harney, MD
Stanford, California
 

Dr. Barbieri responds

Dr. Harney raises the important issue of the potential adverse effects of povidone-iodine surgical preparation when used on a pregnant woman with ruptured membranes. There is very little direct evidence of a toxic effect of povidone-iodine on the fetus, but studies on women report that there is a transient increase in circulating iodine and iodine excretion following a vaginal povidone-iodine preparation.¹ The American College of Obstetricians and Gynecologists has suggested that chlorhexidine might be a superior vaginal disinfectant than povidone-iodine,² but chlorhexidine is not approved by the US Food and Drug Administration for use in the vagina, and many surgical nursing directors favor the use of povidone-iodine in the vagina.³

Another way to prevent post-cesarean delivery infections  

After 40 years in ObGyn practice (I am now retired), I find it interesting that experts have ignored a major potential source of infection--the operation team. Back in the day of Phisohex (hexachlorophene) use, we scrubbed our hands, arms, and fingers for a finite time--10 minutes--systematically and religiously. Our infection rates increased only when house staff rather than surgical assistants "helped" us. When scrubbing, I was always amazed that the house staff appeared at the sink long after I did and left before I had completed my presurgical ritual. (This was not true of non-MD assistants.) And my private practice postoperative infection rate reflected the difference. So perhaps the evidence is skewed away from this source of infection, which I submit may well be the major one!
