Fine Particulate Matter Exposure During Pregnancy Linked to Increased Risk for Spontaneous Preterm Birth
TOPLINE:
Exposure to fine particulate matter (PM2.5) during pregnancy is associated with an increased risk for spontaneous preterm birth, with peak vulnerability in the second trimester. Lower socioeconomic status, limited green space exposure, and extreme heat amplify this risk, whereas living around more trees provides protective effects.
METHODOLOGY:
- The researchers conducted a population-based retrospective cohort study to examine the associations of exposures to total PM2.5 and five constituents (black carbon, nitrate, organic matter, and sulfate) during pregnancy with spontaneous preterm birth.
- They included 409,037 singleton live births from the Kaiser Permanente Southern California health care system between 2008 and 2018, with mothers having a mean age of 30.3 years at delivery (51% Hispanic).
- Daily total PM2.5 concentrations and monthly data on the constituents in California were obtained; mean exposures during the entire pregnancy and in each trimester were calculated.
- Spontaneous preterm births were identified through the evaluation of preterm labor visits and were defined as a delivery occurring before 37 weeks following the onset of spontaneous labor, without pregnancy complications, and within 7 days of the last preterm labor visit.
- The analysis also examined the effect of factors such as race and ethnicity, education, median household income, exposure to green spaces, wildfire smoke, and temperature.
TAKEAWAY:
- Each 2.76 µg/m3 increase in total PM2.5 exposure during pregnancy raised the risk for spontaneous preterm birth by 15% (P < .001), with black carbon showing the highest risk (adjusted odds ratio [aOR], 1.15; 95% CI, 1.12-1.18; P < .001).
- Exposure to PM2.5 during the second trimester showed the highest association with spontaneous preterm birth (aOR, 1.10; P < .001), followed by that during the third (aOR, 1.09; P < .001) and first (aOR, 1.07; P < .001) trimesters.
- Individuals with lower education levels showed a higher risk for spontaneous preterm birth than those with more than 4 years of college education (P = .003).
- Exposure to extreme heat (P < .001) and lower exposure to total green space (P = .003) increased the risk for spontaneous preterm abortion.
IN PRACTICE:
“Targeted and preventive public health interventions among these subpopulations with high risk may be critical for minimizing the burden of spontaneous preterm birth,” the authors wrote.
SOURCE:
The study was led by Anqi Jiao of the program in public health at the Department of Environmental and Occupational Health at the University of California, Irvine. It was published online in JAMA Network Open.
LIMITATIONS:
According to the authors, exposure misclassification was inevitable as individual exposure to PM2.5 was estimated according to census tract-level data without considering personal activity patterns. Only five major PM2.5 constituents were measured due to data availability. Additionally, street-view green space data were considered spatial snapshots, which cannot capture temporal variations, possibly leading to exposure misclassification and biased associations in either direction.
DISCLOSURES:
The study was supported by the National Institute of Environmental Health Sciences and the California Air Resources Board. One author reported receiving research funding from pharmaceutical and biopharmaceutical companies, which was paid to the institute. Another author reported receiving grants from a medical technology company outside the submitted work.

PCOS Linked to Reduced Fertility and Later Childbirth
TOPLINE:
Women with polycystic ovary syndrome (PCOS) have 26% higher nulliparity rates and give birth at more advanced ages despite similar family aspirations and higher rates of fertility treatment. Later PCOS diagnosis is associated with double the rate of advanced maternal age at childbirth.
METHODOLOGY:
- A prospective cohort study followed 14,247 Australian women from 1996 (age, 18-23 years) to 2021 (age, 43-48 years), comparing 981 women with self-reported PCOS against 13,266 without PCOS.
- Participants completed surveys approximately every 3 years, with data collection including childbirth events, fertility issues, and treatment history from 20 weeks of gestational age, including stillbirths.
- Analysis focused on comparing parity, maternal age at deliveries, and factors associated with advanced maternal age between groups, with adjustments made for education level, area of residence, marital status, body mass index group, hypertension, and type 2 diabetes.
TAKEAWAY:
- Compared with women without PCOS, those with PCOS had fewer births (1.9 ± 1.2 vs 1.7 ± 1.3; P < .001) and higher nulliparity rates (18% vs 23%; P = .003).
- PCOS was associated with increased odds of advanced maternal age at first childbirth (adjusted odds ratio [aOR], 1.34; 95% CI, 1.04-1.75) and higher rates of gestational diabetes (aOR, 3.90; 95% CI, 2.99-5.10).
- Late PCOS diagnosis was linked to increased odds of advanced maternal age at first childbirth (aOR, 1.98; 95% CI, 1.22-3.22), emphasizing the importance of early diagnosis.
- Compared with women without PCOS, those with PCOS were older at first childbirth (28.8 ± 5.5 vs 29.5 ± 5.5 years) and second childbirth (31.1 ± 5.0 vs 32.1 ± 5.2 years) (P < .001 for both).
IN PRACTICE:
“Women with PCOS have increased infertility and have higher rates of seeking and using ovulation induction and IVF than those without PCOS. Moreover, women with PCOS are older at both first and second childbirth, have longer interconception periods, are of advanced maternal age, and have higher nulliparity and lower fecundity compared with women without PCOS,” the authors of the study wrote.
SOURCE:
This study was led by Maria Forslund, MD, PhD, Department of Obstetrics and Gynecology, Institute of Clinical Sciences, Sahlgrenska Academy, University of Gothenburg in Sweden. It was published online in American Journal of Obstetrics & Gynecology.
LIMITATIONS:
This study relied on self-reported PCOS diagnosis, though these data were previously validated in the cohort. While dropouts from the study were common, a previous modeling study showed no serious bias in estimates of associations between risk factors and health outcomes in the longitudinal models.
DISCLOSURES:
Forslund received support from the Swedish Medical Society (SLS-984944; SLS986952). The study was funded by the Australian Government’s Department of Health and Aged Care. Additional disclosures are noted in the original article.

New UTI Guideline Offers Treatment Clarity, Reveals Gaps in Knowledge
New recommendations from the WikiGuidelines Group offer strategies for the prevention, diagnosis, and management of urinary tract infections (UTIs) in children and adults.
While the guideline covers a range of clinical topics, including prophylaxis and antimicrobial stewardship, many key clinical questions remain unanswered because of a lack of high-quality evidence, according to lead author Zachary Nelson, PharmD, MPH, of HealthPartners and Park Nicollet Health Services, St. Louis Park, Minnesota, and colleagues.
“This guideline fills a critical gap by providing pragmatic, broadly applicable recommendations tailored for generalist care and systems-based practice,” Nelson and colleagues wrote in JAMA Network Open. “Our guidance is rooted in the best available evidence and is designed for clinicians from various backgrounds and healthcare environments. It emphasizes a patient-centered approach to the diagnosis, prevention, and treatment of UTIs and related genitourinary infections.”
The guideline panelists, including 54 experts from 12 countries, developed the document in accordance with Standards for Quality Improvement Reporting Excellence and the WikiGuidelines charter. The latter requires that “clear recommendations” are based on data from at least two concordant randomized clinical trials (RCTs), or one RCT plus one concordant prospective observational study.
This approach allowed the panel to provide clear recommendations for 6 out of 37 unique questions, while 3 other questions were partially answered. In other words, 75% of the questions lacked sufficient evidence for answers.
“These guidelines are important because they illuminate the clinical data and lack of data we have for approaching diagnosis and treatment of this common infection that leads to a wide array of morbidity and sometimes mortality, as well as significant cost burden to the healthcare system,” said coauthor Sarah Kurz, MD, clinical assistant professor of internal medicine at Michigan Medicine, Ann Arbor, in a written comment.
Jessica Hammett, MD, a urologist at Emory Healthcare, Atlanta, Georgia, who was not an author of the study, suggested that the guideline is additionally impactful because of the panel’s geographic diversity.
“It is an international collaboration that takes into account regional and international practice patterns and differences,” Hammett said in a written comment.
The key guideline recommendations are briefly summarized below.
Preventive Strategies for UTI
The guideline endorses cranberry products as preventive for UTI-prone women, children, and post-intervention patients, though data are insufficient to recommend them for older adults, those with bladder issues, or pregnant women.
Topical estrogen is recommended for postmenopausal women with recurrent UTIs, as it helps restore the vaginal microbiome with minimal systemic absorption. It may also benefit patients with breast cancer when nonhormonal alternatives fail.
For those with intact bladder anatomy, methenamine hippurate is suggested as a noninferior alternative to low-dose antibiotics for preventing recurrent UTIs.
“These findings confirm the best practice of starting postmenopausal women on vaginal estrogen to prevent UTIs, which is a treatment option that should be implemented more commonly,” Hammett said. “Interestingly as compared to the AUA guidelines, this paper recommends the use of cranberry supplementation and methenamine as antibiotic alternatives for preventing UTIs.”
Empirical Treatment Recommendations
According to the guideline, empirical treatment for UTIs should focus on antimicrobials with high urinary tract concentration and local pathogen efficacy.
Nitrofurantoin is recommended for uncomplicated cystitis, while trimethoprim/sulfamethoxazole (TMP/SMX) and first-generation cephalosporins are advised for pyelonephritis.
For intravenous therapy, ceftriaxone is preferred unless there are risk factors for multidrug resistance.
Recommended treatment durations include 5 days for nitrofurantoin, 3 days for TMP/SMX and fluoroquinolones, and a single dose for fosfomycin in acute cystitis cases. For acute pyelonephritis, fluoroquinolones are advised for 5-7 days, with dose-optimized beta-lactams for 7 days. Gram-negative bacteremia from urinary sources warrants a 7-day course.
Stewardship and Clinical Management
The guideline emphasizes antimicrobial stewardship, with support for antibiotic de-escalation and oral regimens where feasible, to reduce adverse effects and hospital stays. Although evidence is limited, the authors suggest thorough allergy assessment and selective reporting of susceptibility results to enhance antibiotic selection.
While data were insufficient to make clear recommendations about the treatment of asymptomatic bacteriuria, Nelson and colleagues suggested that this practice “risks side effects without benefit” while threatening antimicrobial sustainability.
Hammett agreed, noting that “[this] serves as an important reminder not to treat asymptomatic bacteriuria, as it increases side effects and bacterial resistance without any improvement as compared to placebo.”
Special Considerations for Urologic Procedures
Finally, patients undergoing urologic procedures, routine cystoscopy, and urodynamic studies generally do not require prophylactic antibiotics, according to the guideline. Single-dose antibiotic prophylaxis is recommended for low-risk nephrolithotomy patients, though high-risk individuals, such as those who are pregnant or post kidney transplant, may require extended prophylaxis.
Kurz suggested that the guideline consolidates and supports the foundation of evidence driving common practices.
“I don’t think these guidelines offer any strikingly new strategies, which is unsurprising, as they were created after a deep dive into existing literature,” Kurz said. “But more importantly, what I think they do is to highlight where and what the evidence is for many of the clinical strategies that are commonly employed. For example, in terms of prevention, it is common for primary care physicians, urologists, and infectious diseases doctors to recommend cranberry and hydration and to use methenamine. These guidelines highlight that there is sufficient quality and quantity of evidence to support these interventions.”
She also noted how the guidelines emphasize the need for symptoms to make a UTI diagnosis and advise against routine testing of asymptomatic individuals.
“Despite this not being new information, typical clinical practice is often out of step here, and this [guideline] reemphasizes the important factors when considering UTI diagnosis,” Kurz said.
Finally, she expressed frustration for the numerous knowledge gaps remaining in this area, which may be traced back to barriers ranging from the semantic to the more systemic.
“Some of the difficulty is lack of clear definitions and precise terminology regarding UTIs,” Kurz said, noting the unclear distinction between complicated and uncomplicated UTIs. “I would also argue that UTIs are a disease that predominantly affects women, and like many other diseases where this is the case, [they] tend to be less studied. Hopefully, this guideline’s spotlight on all that we do not know can inspire high-quality research to address these gaps, leading to optimal patient care along with decreased burden on the system as a whole in terms of cost and antimicrobial resistance.”
The study was funded by Merck. The WikiGuidelines Group that established this guideline is entirely voluntary and unpaid; the group intends to establish a nonprofit organization to support the development of other guidelines using this novel methodology and eventually intends to trademark the name WikiGuidelines. The authors disclosed relationships with Pfizer, Eumedica, GSK, and others.

The guideline panelists, including 54 experts from 12 countries, developed the document in accordance with Standards for Quality Improvement Reporting Excellence and the WikiGuidelines charter. The latter requires that “clear recommendations” are based on data from at least two concordant randomized clinical trials (RCTs), or one RCT plus one concordant prospective observational study.
This approach allowed the panel to provide clear recommendations for 6 out of 37 unique questions, while 3 other questions were partially answered. In other words, 75% of the questions lacked sufficient evidence for answers.
“These guidelines are important because they illuminate the clinical data and lack of data we have for approaching diagnosis and treatment of this common infection that leads to a wide array of morbidity and sometimes mortality, as well as significant cost burden to the healthcare system,” said coauthor Sarah Kurz, MD, clinical assistant professor of internal medicine at Michigan Medicine, Ann Arbor, in a written comment.
Jessica Hammett, MD, a urologist at Emory Healthcare, Atlanta, Georgia, who was not an author of the study, suggested that the guideline is additionally impactful because of the panel’s geographic diversity.
“It is an international collaboration that takes into account regional and international practice patterns and differences,” Hammett said in a written comment.
The key guideline recommendations are briefly summarized below.
Preventive Strategies for UTI
The guideline endorses cranberry products as preventive for UTI-prone women, children, and post-intervention patients, though data are insufficient to recommend them for older adults, those with bladder issues, or pregnant women.
Topical estrogen is recommended for postmenopausal women with recurrent UTIs, as it helps restore the vaginal microbiome with minimal systemic absorption. It may also benefit patients with breast cancer when nonhormonal alternatives fail.
For those with intact bladder anatomy, methenamine hippurate is suggested as a noninferior alternative to low-dose antibiotics for preventing recurrent UTIs.
“These findings confirm the best practice of starting postmenopausal women on vaginal estrogen to prevent UTIs, which is a treatment option that should be implemented more commonly,” Hammett said. “Interestingly as compared to the AUA guidelines, this paper recommends the use of cranberry supplementation and methenamine as antibiotic alternatives for preventing UTIs.”
Empirical Treatment Recommendations
According to the guideline, empirical treatment for UTIs should focus on antimicrobials with high urinary tract concentration and local pathogen efficacy.
Nitrofurantoin is recommended for uncomplicated cystitis, while trimethoprim/sulfamethoxazole (TMP/SMX) and first-generation cephalosporins are advised for pyelonephritis.
For intravenous therapy, ceftriaxone is preferred unless there are risk factors for multidrug resistance.
Recommended treatment durations include 5 days for nitrofurantoin, 3 days for TMP/SMX and fluoroquinolones, and a single dose for fosfomycin in acute cystitis cases. For acute pyelonephritis, fluoroquinolones are advised for 5-7 days, with dose-optimized beta-lactams for 7 days. Gram-negative bacteremia from urinary sources warrants a 7-day course.
Stewardship and Clinical Management
The guideline emphasizes antimicrobial stewardship, with support for antibiotic de-escalation and oral regimens where feasible, to reduce adverse effects and hospital stays. Although evidence is limited, the authors suggest thorough allergy assessment and selective reporting of susceptibility results to enhance antibiotic selection.
While data were insufficient to make clear recommendations about the treatment of asymptomatic bacteriuria, Nelson and colleagues suggested that this practice “risks side effects without benefit” while threatening antimicrobial sustainability.
Hammett agreed, noting that “[this] serves as an important reminder not to treat asymptomatic bacteriuria, as it increases side effects and bacterial resistance without any improvement as compared to placebo.”
Special Considerations for Urologic Procedures
Finally, patients undergoing urologic procedures, routine cystoscopy, and urodynamic studies generally do not require prophylactic antibiotics, according to the guideline. Single-dose antibiotic prophylaxis is recommended for low-risk nephrolithotomy patients, though high-risk individuals, such as those who are pregnant or post kidney transplant, may require extended prophylaxis.
Kurz suggested that the guideline consolidates and supports the foundation of evidence driving common practices.
“I don’t think these guidelines offer any strikingly new strategies, which is unsurprising, as they were created after a deep dive into existing literature,” Kurz said. “But more importantly, what I think they do is to highlight where and what the evidence is for many of the clinical strategies that are commonly employed. For example, in terms of prevention, it is common for primary care physicians, urologists, and infectious diseases doctors to recommend cranberry and hydration and to use methenamine. These guidelines highlight that there is sufficient quality and quantity of evidence to support these interventions.”
She also noted how the guidelines emphasize the need for symptoms to make a UTI diagnosis and advise against routine testing of asymptomatic individuals.
“Despite this not being new information, typical clinical practice is often out of step here, and this [guideline] reemphasizes the important factors when considering UTI diagnosis,” Kurz said.
Finally, she expressed frustration for the numerous knowledge gaps remaining in this area, which may be traced back to barriers ranging from the semantic to the more systemic.
“Some of the difficulty is lack of clear definitions and precise terminology regarding UTIs,” Kurz said, noting the unclear distinction between complicated and uncomplicated UTIs. “I would also argue that UTIs are a disease that predominantly affects women, and like many other diseases where this is the case, [they] tend to be less studied. Hopefully, this guideline’s spotlight on all that we do not know can inspire high-quality research to address these gaps, leading to optimal patient care along with decreased burden on the system as a whole in terms of cost and antimicrobial resistance.”
The study was funded by Merck. The WikiGuidelines Group that established this guideline is entirely voluntary and unpaid; the group intends to establish a nonprofit organization to support the development of other guidelines using this novel methodology and eventually intends to trademark the name WikiGuidelines. The authors disclosed relationships with Pfizer, Eumedica, GSK, and others.

Endometriosis Raises Rates of Postpartum Depression, Other Disorders
Women with endometriosis have a much higher risk of being diagnosed with several psychiatric disorders during the postpartum period according to an oral abstract presented at the American Society for Reproductive Medicine’s 2024 Scientific Congress and Expo in Denver, Colorado.
Researchers compared rates of postpartum depression, anxiety, mood disturbance (temporary low or anxious mood requiring no treatment), and obsessive-compulsive disorder (OCD) diagnoses among over 200 million adult women from 67 healthcare organizations who had a child between 2005 and 2023.
Within a year after giving birth, women with prepregnancy endometriosis were 25% more likely to be diagnosed with postpartum depression, 85% more likely to be diagnosed with postpartum mood disturbance, 44% more likely to be diagnosed with anxiety, and 1.26 times more likely to be diagnosed with OCD.
About 75% of women studied had no preexisting depression. This population had a 17% higher risk of receiving a postpartum depression diagnosis, a 95% higher risk of receiving an OCD diagnosis, a 72% higher risk of receiving a postpartum mood disturbance diagnosis, and a 38% risk of receiving an anxiety diagnosis.
Among women without preexisting depression, the risk increased by 64% for OCD, 42% for postpartum mood disturbance, and 25% for anxiety, while the risk for postpartum depression was negligible, indicating that women already experiencing depression likely have a higher baseline risk for worsening symptoms postpartum, said the study’s lead author Tina Yi-Jin Hsieh, MD, MPH, biomedical researcher at Harvard Medical School in Boston, Massachusetts.
“We think that because preexisting depression is the more dominant risk factor, it doesn’t really matter if you have another additional risk factor like endometriosis to really change the risk of postpartum depression,” said Hsieh.
Endometriosis is a debilitating condition in which tissue similar to uterine lining grows on the outside of the uterus, causing chronic pain and infertility. It affects between 6% and 10% of women worldwide and takes an average of between 4 and 11 years to be diagnosed. It has been linked to depression and anxiety disorders, yet the study authors say there’s little research examining its impact on women in the year after giving birth.
“Endometriosis is a complex condition that can affect both physical and mental health over much of a person’s life,” said Anna Modest, PhD, assistant professor of Obstetrics, Gynecology, and Reproductive Biology at Harvard Medical School and a study author. “Perinatal and maternal mental health can have a huge impact on children and their family — we need to better understand who is at risk for challenges in the postpartum period.”
“Most chronic medical illnesses, particularly those causing pain, have been shown to increase the risk of mood disorders,” said Ripal Shah, MD, MPH, clinical associate professor of Psychiatry and Behavioral Sciences at Stanford Medicine in California. Shah specializes in reproductive psychiatry and was not associated with the study.
“What’s interesting about endometriosis though is that genome-wide association studies have shown that there may be a genetic predisposition for some women to develop both endometriosis and a mood disorder,” said Shah.
A 2023 study suggested that endometriosis, anxiety, and depression may be connected through a shared genetic basis.
But the experience patients with endometriosis go through also lends itself to the development of mood disorders, said Daniel Ginn, DO, assistant clinical professor of Obstetrics and Gynecology at the David Geffen School of Medicine at the University of California, Los Angeles. Ginn specializes in the treatment of endometriosis and was not a part of the study.
Beyond postpartum depression, Ginn wasn’t surprised by the association of endometriosis with anxiety or OCD because what he hears from patients “on a daily basis is the telling of a history that has been hallmarked by not being listened to, not being believed, and not having symptoms managed well.”
As a result, he said many patients focus heavily on learning about their condition, coming into office visits with binders full of test results and information in an effort to understand and manage it themselves. This “does lead to a certain sense of a need to grasp for control because no one else is helping them [treat their condition effectively].”
He added: “I find it hard to believe that anxiety and OCD were preexisting of the conditions rather than the consequence of a long-term suboptimally managed disease.”
The authors reported no disclosures or sources of funding.

Fibroids: Medical Therapy Not Hysterectomy Should Be First Treatment Choice Interventional Options Case Study
Although hysterectomy remains the most common procedure for treating fibroids and fibroids are the leading indication for hysterectomy, its long-term sequelae make less invasive alternatives the better choice for managing most of these myometrial masses, an invited clinical practice paper in the New England Journal of Medicine (NEJM) asserts.
The practice summary also calls for earlier identification and treatment of fibroid disease and may raise awareness among general gynecologists and primary care physicians less familiar with newer treatments.
Based on a review of evidence and existing formal guidelines, the paper urges wider use of uterus-sparing approaches such as hormone therapy, uterine-artery embolization, focused ultrasound ablation, and radiofrequency ablation. Authored by ob.gyns. Elizabeth A. Stewart, MD, and Shannon K. Laughlin-Tommaso, MD, MPH, of the Mayo Clinic in Rochester, Minnesota, the document also features textbook-style diagrams illustrating procedures.
“To clarify, this is not a new guidance but an invited clinical practice paper,” Laughlin-Tommaso told this news organization. “I believe NEJM recognized the gap in knowledge among all providers, for early diagnosis of uterine fibroids, especially in young patients and those presenting with anemia.”
The less invasive treatments highlighted in the paper can help women recover faster and resume their normal activities more quickly, said Laughlin-Tommaso. “Additionally, many studies have now shown that there are health benefits to keeping the uterus and the ovaries.”
Despite multiple uterine-sparing options, however, a recent study in a commercially insured population found nearly 60% of fibroid patients undergoing hysterectomy had never received a prior conservative treatment.
Why hysterectomy for a benign condition? Hysterectomy, which is universally available in ob.gyn. practices, makes decision-making easier for medical providers and patients, Laughlin-Tommaso explained. “It’s the only treatment that is definitive in that patients will not have bleeding or fibroids in the future and providers don’t have to determine which fibroids to treat or remove.”
More common in Black women, fibroids affect up to 80% of persons with a uterus during their lifetime and up to 50% have symptoms such as heavy and prolonged menstrual bleeding, anemia-associated fatigue, pelvic pressure, and menstrual and nonmenstrual pain, the authors noted. These lesions can also compress nearby structures causing painful intercourse, constipation, and urinary frequency, urgency, or retention.
In 2021 the American College of Obstetricians and Gynecologists issued a practice bulletin on the management of symptomatic uterine leiomyomas, similarly endorsing individualized care that accounts for the desire to preserve fertility or the uterus, increase quality of life, and reduce symptoms. It, too, recommended medical management as first-line treatment for symptomatic fibroids.
“This paper will be helpful for clinicians by covering some of the newer options such as gonadotropin-releasing hormone antagonists introduced in the past 5 years and tailoring treatment to patients depending on whether they still want to conceive,” Sandra M. Hurtado, MD, an ob.gyn. and an assistant professor at UTHealth Houston Medical Center and McGovern Medical School in Houston, Texas, said in an interview. “And the illustrations will be useful to doctors who are not gynecologists and will help to explain the interventional options to patients,” added Hurtado, who was not involved in the paper.
Offering another outside perspective on the paper, Charles J. Ascher-Walsh, MD, senior system vice chair for gynecology and division director of urogynecology in the Raquel and Jaime Gilinski Department of Obstetrics, Gynecology and Reproductive Science at Mount Sinai in New York City, called it a useful though not new summary. Reaching the wider audience of NEJM may raise awareness of newer fibroid therapies among general, nonspecialist ob.gyns., whose practices may concentrate largely on obstetrics, he added, “and the excellent illustrations clarify the treatment options.” In his view, broader awareness may increase much-needed funding for this neglected area of research.
Among the paper’s recommendations:
Diagnosis
Pelvic ultrasonography is the most cost-effective imaging method, providing information on size, location, and number of fibroids and ruling out adnexal masses. It is limited, however, by less-accurate resolution if the uterine volume is greater than 375 mL or if fibroids number more than four.
Medical Alternatives to Hysterectomy
Early diagnosis and first-line medical therapies are recommended.
Contraceptive hormones to control heavy menstrual bleeding are the first step in most algorithms for treating fibroid-related bleeding, despite low-quality evidence.
Nonsteroidal anti-inflammatory agents and tranexamic acid during menstruation also limit heavy menses but have more evidence of efficacy for idiopathic heavy menses.
Gonadotropin-releasing hormone (GnRH) agonists in depot form are approved for short-term preoperative therapy. While they cause amenorrhea in nearly 90% of patients and reduce uterine volume by 30%-60%, they have a high incidence of hypogonadal symptoms, including bone loss and hot flushes. They also cause a “steroidal flare” when the stored gonadotropins are released and cause subsequent heavy menstrual bleeding with the rapid decrease in estrogen levels.
Oral GnRH antagonist combinations are a major therapeutic advance, pairing a GnRH antagonist (such as elagolix or relugolix, which rapidly inhibit ovarian steroidogenesis) with estradiol and progestin at doses equivalent to systemic levels in the early follicular phase of the menstrual cycle.
In clinical trials these combinations decreased heavy menstrual bleeding by 50%-75%, pain by 40%-50%, and bulk-related symptoms through a 10% decrease in uterine volume. Side effects are few, with hot flushes, headaches, and nausea occurring in fewer than 20% of participants.
Smaller fibroids in the submucosal to intramural spaces can be treated transcervically, while larger lesions of any type or smaller subserosa fibroids are treated abdominally.
Uterine-artery embolization uses minimally invasive radiologically guided catheterization to release embolic particles directly into both uterine arteries. This process causes ischemic infarction of the fibroids and decreases bleeding, pain, and bulk-related symptoms.
Other procedures shrink individual fibroids with energy that creates coagulative necrosis. These include focused ultrasound ablation (with MRI or ultrasound guidance) and radiofrequency ablation (with laparoscopic or transcervical ultrasound guidance).
Unlike uterine-artery embolization, which treats all fibroids concurrently, these therapies require individual targeting of fibroids.
Radiofrequency ablation can be done concurrently with other surgical therapies, such as laparoscopic excision of endometriosis or hysteroscopic myomectomy.
Myomectomy, or the surgical removal of fibroids, is most often used in persons actively seeking pregnancy or having very large fibroids in whom shrinkage would be inadequate. Most guidelines recommend surgical excision rather than shrinking procedures to optimize fertility. However, myomectomy often commits patients to future cesarean section, which increases pregnancy-related morbidity.
Although myomectomy is seen as superior to uterine-artery embolization for improving quality of life, both approaches provide substantial symptom relief.
Recurrence
Incidence of recurring fibroids is high, with, for example, new fibroids developing in approximately 50% of persons within 5 years of myomectomy.
Earlier this year, a large cohort study reported that myomectomy was best for avoiding reintervention after surgical leiomyoma management.
Reintervention rates vary according to procedure, patient age, disease extent, and symptoms and can be as high as 33% up to 5 years after treatment, with lower percentages seen among persons older than 45 years of age.
Hysterectomy
Minimally invasive hysterectomy is recommended. Drawbacks to hysterectomy include perioperative risk and concomitant oophorectomy, which was common until the early 2000s when large cohort studies showed elevated risks of death, cardiovascular disease, dementia, and other illnesses compared with hysterectomy plus ovarian conservation. Oophorectomy but not hysterectomy rates have since decreased.
Still needing study, according to Laughlin-Tommaso are the underlying reasons for health disparities in fibroids, especially among Black and Latina individuals. “Some studies have found associations with vitamin D deficiency and with stress and racism,” she said.
Looking ahead, the authors stressed the need for a fibroid risk-prediction model, a staging system, and large randomized trials of treatment effectiveness. Also needed are methods for primary and secondary prevention. “Earlier screening and medical treatment in primary care settings could potentially minimize morbidity and the incidence of unnecessary hysterectomies, and primary care–based screening trials are warranted,” they wrote.
In addition to procedural illustrations the practice document includes a vignette of a 33-year-old never-pregnant Black woman (but desiring motherhood) with heavy menstrual bleeding, abdominal bloating, and non–iron deficiency anemia. Evaluation for thalassemia and sickle cell anemia is negative, but ultrasonography reveals an enlarged uterus with multiple fibroids and normal ovaries.
In line with the clinical review, the authors prescribe oral GnRH agonist combination therapy, plus iron and multivitamin supplementation, and recommend annual reassessment — earlier if pregnancy is desired or if symptoms escalate. Since the patient prioritizes fertility, hysterectomy would be appropriate only if she had biopsy-proven cancer.
The authors received no external funding for this practice paper, but both have funding from the National Institutes of Health for fibroid research. Laughlin-Tommaso reported royalties from UpToDate. Stewart reported research support from the Agency for Healthcare Research and Quality, and speaking, data-monitoring, and consulting fees for various private companies, including AbbVie, Anylam Pharmaceuticals, ASKA Pharma, and Myovant Sciences. She holds a patent on treatment for abnormal uterine bleeding and has been involved in CME for various medical educational agencies. Hurtado and Ascher-Walsh had no relevant conflicts of interest to declare.

Reintervention rates vary according to procedure, patient age, disease extent, and symptoms and can be as high as 33% up to 5 years after treatment, with lower percentages seen among persons older than 45 years of age.
Hysterectomy
Minimally invasive hysterectomy is recommended. Drawbacks to hysterectomy include perioperative risk and concomitant oophorectomy, which was common until the early 2000s when large cohort studies showed elevated risks of death, cardiovascular disease, dementia, and other illnesses compared with hysterectomy plus ovarian conservation. Oophorectomy but not hysterectomy rates have since decreased.
Still needing study, according to Laughlin-Tommaso are the underlying reasons for health disparities in fibroids, especially among Black and Latina individuals. “Some studies have found associations with vitamin D deficiency and with stress and racism,” she said.
Looking ahead, the authors stressed the need for a fibroid risk-prediction model, a staging system, and large randomized trials of treatment effectiveness. Also needed are methods for primary and secondary prevention. “Earlier screening and medical treatment in primary care settings could potentially minimize morbidity and the incidence of unnecessary hysterectomies, and primary care–based screening trials are warranted,” they wrote.
In addition to procedural illustrations the practice document includes a vignette of a 33-year-old never-pregnant Black woman (but desiring motherhood) with heavy menstrual bleeding, abdominal bloating, and non–iron deficiency anemia. Evaluation for thalassemia and sickle cell anemia is negative, but ultrasonography reveals an enlarged uterus with multiple fibroids and normal ovaries.
In line with the clinical review, the authors prescribe oral GnRH agonist combination therapy, plus iron and multivitamin supplementation, and recommend annual reassessment — earlier if pregnancy is desired or if symptoms escalate. Since the patient prioritizes fertility, hysterectomy would be appropriate only if she had biopsy-proven cancer.
The authors received no external funding for this practice paper, but both have funding from the National Institutes of Health for fibroid research. Laughlin-Tommaso reported royalties from UpToDate. Stewart reported research support from the Agency for Healthcare Research and Quality, and speaking, data-monitoring, and consulting fees for various private companies, including AbbVie, Anylam Pharmaceuticals, ASKA Pharma, and Myovant Sciences. She holds a patent on treatment for abnormal uterine bleeding and has been involved in CME for various medical educational agencies. Hurtado and Ascher-Walsh had no relevant conflicts of interest to declare.

Although hysterectomy remains the most common procedure for treating fibroids and fibroids are the leading indication for hysterectomy, its long-term sequelae make less invasive alternatives the better choice for managing most of these myometrial masses, an invited clinical practice paper in the New England Journal of Medicine (NEJM) asserts.
The practice summary also calls for earlier identification and treatment of fibroid disease and may raise awareness among general gynecologists and primary care physicians less familiar with newer treatments.
Based on a review of evidence and existing formal guidelines, the paper urges wider use of uterus-sparing approaches such as hormone therapy, uterine-artery embolization, focused ultrasound ablation, and radiofrequency ablation. Authored by ob.gyns. Elizabeth A. Stewart, MD, and Shannon K. Laughlin-Tommaso, MD, MPH, of the Mayo Clinic in Rochester, Minnesota, the document also features textbook-style diagrams illustrating procedures.
“To clarify, this is not a new guidance but an invited clinical practice paper,” Laughlin-Tommaso told this news organization. “I believe NEJM recognized the gap in knowledge among all providers, for early diagnosis of uterine fibroids, especially in young patients and those presenting with anemia.”
The less invasive treatments highlighted in the paper can help women recover faster and resume their normal activities more quickly, said Laughlin-Tommaso. “Additionally, many studies have now shown that there are health benefits to keeping the uterus and the ovaries.”
Despite multiple uterine-sparing options, however, a recent study in a commercially insured population found nearly 60% of fibroid patients undergoing hysterectomy had never received a prior conservative treatment.
Why hysterectomy for a benign condition? Hysterectomy, which is universally available in ob.gyn. practices, makes decision-making easier for medical providers and patients, Laughlin-Tommaso explained. “It’s the only treatment that is definitive in that patients will not have bleeding or fibroids in the future and providers don’t have to determine which fibroids to treat or remove.”
More common in Black women, fibroids affect up to 80% of persons with a uterus during their lifetime and up to 50% have symptoms such as heavy and prolonged menstrual bleeding, anemia-associated fatigue, pelvic pressure, and menstrual and nonmenstrual pain, the authors noted. These lesions can also compress nearby structures causing painful intercourse, constipation, and urinary frequency, urgency, or retention.
In 2021 the American College of Obstetricians and Gynecologists issued a practice bulletin on the management of symptomatic uterine leiomyomas, similarly endorsing individualized care that accounts for the desire to preserve fertility or the uterus, increase quality of life, and reduce symptoms. It, too, recommended medical management as first-line treatment for symptomatic fibroids.
“This paper will be helpful for clinicians by covering some of the newer options such as gonadotropin-releasing hormone antagonists introduced in the past 5 years and tailoring treatment to patients depending on whether they still want to conceive,” Sandra M. Hurtado, MD, an ob.gyn. and an assistant professor at UTHealth Houston Medical Center and McGovern Medical School in Houston, Texas, said in an interview. “And the illustrations will be useful to doctors who are not gynecologists and will help to explain the interventional options to patients,” added Hurtado, who was not involved in the paper.
Offering another outside perspective on the paper, Charles J. Ascher-Walsh, MD, senior system vice chair for gynecology and division director of urogynecology in the Raquel and Jaime Gilinski Department of Obstetrics, Gynecology and Reproductive Science at Mount Sinai in New York City, called it a useful though not new summary. Reaching the wider audience of NEJM may raise awareness of newer fibroid therapies among general, nonspecialist ob.gyns., whose practices may concentrate largely on obstetrics, he added, “and the excellent illustrations clarify the treatment options.” In his view, broader awareness may increase much-needed funding for this neglected area of research.
Among the paper’s recommendations:
Diagnosis
Pelvic ultrasonography is the most cost-effective imaging method, providing information on size, location, and number of fibroids and ruling out adnexal masses. It is limited, however, by less-accurate resolution if the uterine volume is greater than 375 mL or if fibroids number more than four.
Medical Alternatives to Hysterectomy
Early diagnosis and first-line medical therapies are recommended.
Contraceptive hormones to control heavy menstrual bleeding are the first step in most algorithms for treating fibroid-related bleeding, despite low-quality evidence.
Nonsteroidal anti-inflammatory agents and tranexamic acid during menstruation also limit heavy menses but have more evidence of efficacy for idiopathic heavy menses.
Gonadotropin-releasing hormone (GnRH) agonists in depot form are approved for short-term preoperative therapy. While they cause amenorrhea in nearly 90% of patients and reduce uterine volume by 30%-60%, they have a high incidence of hypogonadal symptoms, including bone loss and hot flushes. They also cause a “steroidal flare” when the stored gonadotropins are released and cause subsequent heavy menstrual bleeding with the rapid decrease in estrogen levels.
Oral GnRH antagonist combinations are a major therapeutic advance, pairing a GnRH antagonist (such as elagolix or relugolix, which rapidly inhibit ovarian steroidogenesis) with estradiol and progestin at doses equivalent to systemic levels in the early follicular phase of the menstrual cycle.
In clinical trials these combinations decreased heavy menstrual bleeding by 50%-75%, pain by 40%-50%, and bulk-related symptoms through a 10% decrease in uterine volume. Side effects are few, with hot flushes, headaches, and nausea occurring in fewer than 20% of participants.
Smaller fibroids in the submucosal to intramural spaces can be treated transcervically, while larger lesions of any type or smaller subserosa fibroids are treated abdominally.
Uterine-artery embolization uses minimally invasive radiologically guided catheterization to release embolic particles directly into both uterine arteries. This process causes ischemic infarction of the fibroids and decreases bleeding, pain, and bulk-related symptoms.
Other procedures shrink individual fibroids with energy that creates coagulative necrosis. These include focused ultrasound ablation (with MRI or ultrasound guidance) and radiofrequency ablation (with laparoscopic or transcervical ultrasound guidance).
Unlike uterine-artery embolization, which treats all fibroids concurrently, these therapies require individual targeting of fibroids.
Radiofrequency ablation can be done concurrently with other surgical therapies, such as laparoscopic excision of endometriosis or hysteroscopic myomectomy.
Myomectomy, or the surgical removal of fibroids, is most often used in persons actively seeking pregnancy or having very large fibroids in whom shrinkage would be inadequate. Most guidelines recommend surgical excision rather than shrinking procedures to optimize fertility. However, myomectomy often commits patients to future cesarean section, which increases pregnancy-related morbidity.
Although myomectomy is seen as superior to uterine-artery embolization for improving quality of life, both approaches provide substantial symptom relief.
Recurrence
Incidence of recurring fibroids is high, with, for example, new fibroids developing in approximately 50% of persons within 5 years of myomectomy.
Earlier this year, a large cohort study reported that myomectomy was best for avoiding reintervention after surgical leiomyoma management.
Reintervention rates vary according to procedure, patient age, disease extent, and symptoms and can be as high as 33% up to 5 years after treatment, with lower percentages seen among persons older than 45 years of age.

Minimally invasive hysterectomy is recommended. Drawbacks to hysterectomy include perioperative risk and concomitant oophorectomy, which was common until the early 2000s when large cohort studies showed elevated risks of death, cardiovascular disease, dementia, and other illnesses compared with hysterectomy plus ovarian conservation.

Update Coming for Thyroid Disease in Pregnancy Guidelines
CHICAGO — A preview of much-anticipated updates to guidelines on managing thyroid disease in pregnancy shows key changes to recommendations in the evolving field, ranging from consideration of the chance of spontaneous normalization of thyroid levels during pregnancy to a heightened emphasis on shared decision-making and the nuances can factor into personalized treatment.
The guidelines, expected to be published in early 2025, have not been updated since 2017, and with substantial advances and evidence from countless studies since then, the new guidelines were developed with a goal to start afresh, said ATA Thyroid and Pregnancy Guidelines Task Force cochair Tim IM Korevaar, MD, PhD, in presenting the final draft guidelines at the American Thyroid Association (ATA) 2024 Meeting.
“Obviously, we’re not going to ignore the 2017 guidelines, which have been a very good resource for us so far, but we really wanted to start from scratch and follow a ‘blank canvas’ approach in optimizing the evidence,” said Korevaar, an endocrinologist and obstetric internist with the Division of Pharmacology and Vascular Medicine & Academic Center for Thyroid Diseases, Department of Internal Medicine, Erasmus University Medical Center, Rotterdam, The Netherlands.
The guidelines, developed through a collaborative effort involving a wide variety of related medical societies, involved 14 systematic literature reviews. While the pregnancy issues covered by the guidelines is extensive, key highlights include:
Management in Preconception
Beginning with preconception, a key change in the guidelines will be that patients with euthyroid thyroid peroxidase (TPO) antibodies, which can be indicative of thyroid dysfunction, routine treatment with levothyroxine is not recommended, based on new evidence from randomized trials of high-risk patients showing no clear benefit from the treatment.
“In these trials, and across analyses, there was absolutely no beneficial effect of levothyroxine in these patients [with euthyroid TPO antibody positivity],” he said.
With evidence showing, however, that TPO antibody positivity can lead to subclinical or overt hypothyroidism within 1 or 2 years, the guidelines will recommend that TPO antibody–positive patients do have thyroid stimulating hormone (TSH) levels tested every 3-6 months until pregnancy, and existing recommendations to test during pregnancy among those patients remain in place, Korevaar reported.
In terms of preconception subclinical hypothyroidism, the guidelines will emphasize the existing recommendation “to always strive to reassess” thyroid levels, and if subclinical hypothyroidism does persist, to treat with low-dose levothyroxine.
During Pregnancy
During pregnancy, the new proposed recommendations will reflect the important change that three key risk factors, including age over 30 years, having at least two prior pregnancies, and morbid obesity (body mass index [BMI] at least 40 kg/m2), previously considered a risk for thyroid dysfunction in pregnancy, should not, on their own, suggest the need for thyroid testing, based on low evidence of an increased risk in pregnancy.
Research on the issue includes a recent study from Korevaar’s team showing these factors to in fact have low predictability of thyroid dysfunction.
“We deemed that these risk differences weren’t really clinically meaningful (in predicting risk), and so we have removed to maternal age, BMI, and parity as risk factors for thyroid testing indications in pregnancy,” Korevaar said.
Factors considered a risk, resulting in recommended testing at presentation include a history of subclinical or clinical hypo- or hyperthyroidism, postpartum thyroiditis, known thyroid antibody positivity, symptoms of thyroid dysfunction or goiter, and other factors.
Treatment for Subclinical Hypothyroidism in Pregnancy
Whereas current guidelines recommend TPO antibody status in determining when to consider treatment for subclinical hypothyroidism, the new proposed guideline will instead recommend treatment based on the timing of the diagnosis of the subclinical hypothyroidism, with consideration of treatment during the first trimester, but not in the second or third trimester, based on newer evidence of the absolute risk for pregnancy complications and randomized trial data.
“The recommendations are now to no longer based on TPO antibody status, but instead according to the timing of the diagnosis of subclinical hypothyroidism,” Korevaar said.
Based on the collective data, “due to the low risk, we do not recommend for routine levothyroxine treatment in the second or third trimester groups with TSH levels under 10 mU/L now.”
“However, for subclinical hypothyroidism diagnosed in the first trimester, the recommendation would be that you can consider levothyroxine treatment,” he said.
While a clear indication for treatment in any trimester is the presence of overt hypothyroidism, or TSH levels over 10 mU/L, Korevaar underscored the importance of considering nuances of the recommendations that may warrant flexibility, for instance among patients with borderline TSH levels.
Spontaneous Normalization of Thyroid Levels in Pregnancy
Another new recommendation addresses the issue of spontaneous normalization of abnormal thyroid function during pregnancy, with several large studies showing a large proportion of subclinical hypothyroidism cases spontaneously revert to euthyroidism by the third trimester — despite no treatment having been provided.
Under the important proposed recommendation, retesting of subclinical hypothyroidism is suggested within 3 weeks.
“The data shows that a large proportion of patients spontaneously revert to euthyroidism,” Korevaar said.
“Upon identifying subclinical hypothyroidism in the first trimester, there will be essentially two options that clinicians can discuss with their patient — one would be to consider confirmatory tests in 3 weeks or to discuss the starting the lower dose levothyroxine in the first trimester,” he said.
In terms of overt hypothyroidism, likewise, if patients have a TSH levels below 6 mU/L in pregnancy, “you can either consider doing confirmatory testing within 3 weeks, or discussing with the patient starting levothyroxine treatment,” Korevaar added.
Overt Hyperthyroidism
For overt hyperthyroidism, no significant changes from current guidelines are being proposed, with the key exception of a heightened emphasis on the need for shared decision-making with patients, Korevaar said.
“We want to emphasize shared decision-making especially for women who have Graves’ disease prior to pregnancy, because the antithyroid treatment modalities, primarily methimazole (MMI) and propylthiouracil (PTU), have different advantages and disadvantages for an upcoming pregnancy,” he said.
“If you help a patient become involved in the decision-making process, that can also be very helpful in managing the disease and following-up on the pregnancy.”
Under the recommendations, PTU remains the preferred drug in overt hyperthyroidism, due to a more favorable profile in terms of potential birth defects vs MMI, with research showing a higher absolute risk of 3% vs 5%.
The guidelines further suggest the option of stopping the antithyroid medications upon a positive pregnancy test, with the exception of high-risk patients.
Korevaar noted that, if the treatment is stopped early in pregnancy, relapse is not likely to occur until after approximately 3 months, or 12 weeks, at which time, the high-risk teratogenic period, which is between week 5 and week 15, will have passed.
Current guidelines regarding whether to stop treatment in higher-risk hyperthyroid patients are recommended to remain unchanged.
Thyroid Nodules and Cancer
Recommendations regarding thyroid nodules and cancer during pregnancy are also expected to remain largely similar to those in the 2017 guidelines, with the exception of an emphasis on simply considering how the patient would normally be managed outside of pregnancy.
For instance, regarding the question of whether treatment can be withheld for 9 months during pregnancy. “A lot of times, the answer is yes,” Korevaar said.
Other topics that will be largely unchanged include issues of universal screening, definitions of normal and abnormal TSH and free T4 reference ranges and isolated hypothyroxinemia.
Steps Forward in Improving Updates, Readability
In addition to recommendation updates, the new guidelines are being revised to better reflect more recent evidence-based developments and user-friendliness.
“We have now made the step to a more systematic and replicable methodology to ensure for easier updates with a shorter interval,” Korevaar told this news organization.
“Furthermore, since 2006, the ATA guideline documents have followed a question-and-answer format, lacked recommendation tables and had none or only a few graphic illustrations,” he added.
“We are now further developing the typical outline of the guidelines to improve the readability and dissemination of the guideline document.”
Korevaar’s disclosures include lectureship fees from IBSA, Merck, and Berlin Chemie.

In addition to recommendation updates, the new guidelines are being revised to better reflect more recent evidence-based developments and user-friendliness.
“We have now made the step to a more systematic and replicable methodology to ensure for easier updates with a shorter interval,” Korevaar told this news organization.
“Furthermore, since 2006, the ATA guideline documents have followed a question-and-answer format, lacked recommendation tables and had none or only a few graphic illustrations,” he added.
“We are now further developing the typical outline of the guidelines to improve the readability and dissemination of the guideline document.”
Korevaar’s disclosures include lectureship fees from IBSA, Merck, and Berlin Chemie.

Postpartum Exercise Reduces Depression and Anxiety Symptoms
TOPLINE:
Postpartum exercise reduces the severity of depressive and anxiety symptoms. Initiating exercise within 12 weeks post partum is linked to greater reductions in depressive symptoms.
METHODOLOGY:
- Researchers conducted a systematic review and meta-analysis including 35 studies with a total of 4072 participants.
- The review included randomized controlled trials and nonrandomized interventions examining the impact of postpartum exercise on depression and anxiety.
- Participants were postpartum individuals within the first year after childbirth, with interventions including various types of exercise.
- Data sources included online databases with data up to January 2024, reference lists, and hand searches.
- The Grading of Recommendations, Assessment, Development, and Evaluation framework was used to assess the certainty of evidence.
TAKEAWAY:
- Postpartum exercise-only interventions resulted in a moderate reduction in the severity of depressive symptoms (standardized mean difference [SMD], –0.52; 95% CI, –0.80 to –0.24).
- Exercise-only interventions were associated with a small reduction in the severity of anxiety symptoms (SMD, –0.25; 95% CI, –0.43 to –0.08).
- Initiating exercise within 12 weeks post partum was associated with a greater reduction in depressive symptoms, compared with starting later.
- Postpartum exercise was associated with a 45% reduction in the odds of developing depression (odds ratio, 0.55; 95% CI, 0.32-0.95).
IN PRACTICE:
“Further investigation should aim to investigate the effects of postpartum exercise in individuals who experienced perinatal complications and in those who had limitations to exercise during pregnancy. Additionally, more investigation is required to address the possible lasting effects of postpartum exercise on maternal mental health as there were very limited studies reporting on this outcome,” the authors of the study wrote.
SOURCE:
This study was led by Margie H. Davenport, University of Alberta in Edmonton, Canada. It was published online in British Journal of Sports Medicine.
LIMITATIONS:
This study’s limitations included high heterogeneity among included studies, small sample sizes in some studies, and the combination of exercise with other interventions in some cases. These factors may have affected the generalizability and precision of the findings.
DISCLOSURES:
This study was funded by the Christenson Professorship in Active Healthy Living. Davenport is funded by a Christenson Professorship in Active Healthy Living.

Are GLP-1s the Newest Fertility Treatment?
First, there were “Ozempic babies.” Now, there is also Ozempic-before-baby.
Unplanned pregnancies are still regularly being reported among people using glucagon-like peptide 1 receptor agonist (GLP-1 RA) drugs, and now fertility specialists are increasingly incorporating the medicines into preconception care plans.
The specialists say their colleagues in other areas of medicine may have an opportunity, too, to talk about weight loss using these new drugs in terms of reproductive health. Motivation and compliance can transform when the goal isn’t simply weight loss but having children.
“We have this really special moment to help patients be healthier, in order to be healthier for their kids,” said Christina Boots, MD, MSci, an associate professor of reproductive endocrinology and infertility at Northwestern University’s Feinberg School of Medicine, Chicago. “And I think that’s also a very motivating moment. It may be hard to get up and go for a run to make my jeans fit better, but when I think about it in terms of, ‘this might someday help my future daughter,’ that is a whole different level of motivation.”
Here’s why, what to know about the current lengthy list of unknowns and risks, and some options for approaching the topic with patients.
What Fertility Docs Are Doing
While overweight and obesity are consistently linked to fertility and pregnancy outcomes, Boots predicts the biggest impact of GLP-1 weight loss for fertility among women will be a specific subset: Those who are not cycling regularly, such as those with polycystic ovary syndrome (PCOS).
“The women who are cycling regularly who have very unexplained infertility and no other comorbidities like high blood pressure or something else going on, I don’t think it’s going to help their fertility very much at all,” she said “It might, but I think there’s probably something else going on in her tubes or with her eggs or his sperm, but it has nothing to do with her metabolic health.
Women who aren’t cycling regularly will benefit, but those with truly unexplained fertility probably won’t, she said.
In their recent narrative review on treating obesity and fertility with GLP-1 RAs that appeared in Fertility and Sterility, Boots and co-author Alyse S. Goldberg, MD, an endocrinologist with the University of Toronto, Ontario, Canada, advocate for the use of GLP-1s as a go-to treatment for obesity as part of preconception care by reproductive endocrinologists, calling the drugs “the most effective, least invasive means of weight loss.”
The paper is timely and necessary because use of GLP-1s is only going to increase, Patricia Jimenez, MD, an associate professor of obstetrics and gynecology at Washington University School of Medicine in St. Louis, Missouri, said in an email to this news organization.
“GLP-1 RAs are becoming a larger part of my practice. More patients are either using them already or interested in using them,” said Jimenez, who is board certified in reproductive endocrinology, obstetrics and gynecology, and obesity medicine. “I specifically see patients to discuss this and do prescribe antiobesity medications, not only GLP-1 RAs. Often this is with people with PCOS who are not planning to conceive soon or patients willing to delay fertility treatment [by] 3-6 months.”
Treating obesity is also important for women who are seeking in vitro fertilization, Boots said, because many IVF clinics have a body mass index cutoff of 40 kg/m2.
Like Jimenez’s approach, Boots and Goldberg call for comprehensive obesity care beyond the use of medication, including nutritional counseling and mental health support. Those supports are important during the transition off of GLP-1 medications, which poses a risk for rapid weight regain. That’s even with the potential support of taking metformin, which Boots often prescribes as a bridge.
Semaglutide should be stopped at least 2 months prior to conception, and tirzepatide should be stopped 1 month prior to conception, according to the manufacturers. (Boots and Goldberg listed the Canadian label recommendation for stopping tirzepatide, noting there is no suggested timeline for stopping prior to conception on the US label.)
Numerous studies have shown rapid weight regain is common when stopping GLP-1s, which presents a unique set of risks for pregnant women including early pregnancy loss, gestational diabetes, preeclampsia, and nonelective cesarean delivery.
Weighing Risks, Benefits, and Unknowns
Early looks at small human data sets, mostly involving semaglutide and earlier short-acting GLP-1s, and their impact on the risk for birth defects are “reassuring,” Boots said.
“But birth defects are just one small aspect. There’s also metabolic health and things like that long-term. Understanding what it does to the growing baby and the proximity of that medication to that growing baby is really important to see, and can’t be answered with animal studies, not perfectly anyway,” Boots said.
There are no published reports, from clinical trials nor case collections, examining the use of tirzepatide among pregnant people.
“One of the most important questions we need to answer is the preconception safety of these medications, and that includes safety for men,” Joshua Halpern, MD, MS, an adjunct assistant professor of urology at Northwestern University’s Feinberg School of Medicine, and chief scientific officer for Posterity Health, said in an email to this news organization.
“For example, a recent study found that men who were taking metformin, another popular medication for diabetes, were more likely to have children with birth defects, compared with those who were not taking the medication,” Halpern said. “Further studies are needed to determine whether a similar effect might hold true for the GLP-1 agonists.”
Small early studies on sperm are encouraging, Halpern said, suggesting that GLP-1 use may be beneficial, but a better understanding of direct effects is needed.
Among women, there may be cases where continuing use of a GLP-1 during pregnancy may offer benefits that outweigh risks, Boots suggested. Manufacturers have also created pregnancy exposure registries to measure the safety of their therapies during pregnancy.
“I have a group of patients whose sugars are so well controlled on these medications, but as soon as they come off, they get weight regain and their glucose is just so poorly controlled,” she said. “There may be a group of women where the benefits of glucose control outweigh the risks of being on the medication the whole pregnancy.”
The list of important unknowns also includes a need to examine how rapid weight loss may impact ovulation rates and spontaneous conception, as well as miscarriage rates, birth weight, and metabolic health of the child.
More detailed rebound weight gain data is coming next year, with additional analysis expected as well on birth weight and pregnancy outcomes, said Jacqueline Maya, MD, first author of the research abstract presented at this year’s American Diabetes Association conference that examined gestational weight gain among people with preexisting type 2 diabetes who were exposed to GLP-1s during pregnancy. The study included 47 exposed pregnancies (based on prescription records and electronic chart information) and compared gestational weight gain to 141 unexposed matched pregnancies. Among the exposed group, 62% exceeded recommended weight gain, compared with 41% in the unexposed group. On average, gestational weight gain in exposed pregnancies exceeded that among matched unexposed pregnancies by about 6 pounds.
The team is now working with an additional data set to examine exposed pregnancies among people with obesity, said Maya, an instructor of pediatrics at Mass General Hospital and Harvard School of Medicine. She is particularly interested in examining weight trajectories during pregnancy to see how they may affect fetal outcomes. Her team’s current project also will likely include analysis to examine other variables like postpartum weight gain and adiposity characteristics of the baby.
Maya said the team hopes to have more to report at the American Diabetes Association conference in June next year.
Offer the Conversation
Using a GLP-1 for weight loss takes time, usually around 1 year to reach a plateau. Boots encouraged nonfertility providers to ask patients of reproductive age about their family plans as an opening.
“I hope for all primary care doctors and gynecologists, that with any patient of reproductive age, you should be bringing this up, asking, ‘Have you thought about having kids? Are you thinking about it soon?’ And if they say they are sometime in the near future, then you can say, ‘Is it OK if I bring up your weight?’ And you should ask permission.”
If the patient declines, it’s OK to bring it up again at a future visit.
“People with obesity have often experienced negative weight bias that impacts their care,” Jimenez said. “Treat obesity as a disease, not a personal failing. Ask permission to discuss weight with the patient beforehand. If they say no, respect that answer. This goes a long way in developing a positive relationship, so they return for care and may be willing to discuss later.”
When patients are open to the conversation, Boots suggests not focusing on the potential for poor outcomes, and instead perhaps saying, “If you’re thinking about having a baby in 5 years, optimizing your health now will not only make your pregnancy healthier, but your child healthier long-term.”
Discussing contraception plans remains important. People starting semaglutide or tirzepatide should use contraception other than oral birth control for 4 weeks while starting the medicine and for 4 weeks after each dose increase.
Boots said that the contraception conversation is particularly important because many people have come to deeply believe that they are infertile and, thus, may perhaps think contraception advice doesn’t apply to them. Maya hypothesized that behavioral changes following weight loss may also be a pathway toward pregnancy.
“Pregnancy while on GLP-1 RAs does happen. I always have a discussion about this possibility and contraception. This can sometimes be challenging for people with infertility to consider,” Jimenez said. “Explaining the risks, benefits, and unknowns can help. As the [Fertility and Sterility] paper describes, the limited data available has not shown increased fetal or maternal complications. We need more high quality data to better understand the impact of exposure or use around the time of conception and during pregnancy.”
It’s also important to introduce the idea to patients that they may someday need to come off the medications, such as when they are ready to have children, and how important lifestyle and behavioral changes will be at that time, Maya said.
“We do know what the alternative is, and we do know what the risks of obesity are,” she said. “So, it’s a tug and pull. We’re not starting off with healthy. We’re starting off with a disease that is physically and emotionally very difficult for the patient, especially when it starts in childhood.”

“I have a group of patients whose sugars are so well controlled on these medications, but as soon as they come off, they get weight regain and their glucose is just so poorly controlled,” she said. “There may be a group of women where the benefits of glucose control outweigh the risks of being on the medication the whole pregnancy.”
The list of important unknowns also includes a need to examine how rapid weight loss may impact ovulation rates and spontaneous conception, as well as miscarriage rates, birth weight, and metabolic health of the child.
More detailed rebound weight gain data is coming next year, with additional analysis expected as well on birth weight and pregnancy outcomes, said Jacqueline Maya, MD, first author of the research abstract presented at this year’s American Diabetes Association conference that examined gestational weight gain among people with preexisting type 2 diabetes who were exposed to GLP-1s during pregnancy. The study included 47 exposed pregnancies (based on prescription records and electronic chart information) and compared gestational weight gain to 141 unexposed matched pregnancies. Among the exposed group, 62% exceeded recommended weight gain, compared with 41% in the unexposed group. On average, gestational weight gain in exposed pregnancies exceeded that among matched unexposed pregnancies by about 6 pounds.
The team is now working with an additional data set to examine exposed pregnancies among people with obesity, said Maya, an instructor of pediatrics at Mass General Hospital and Harvard School of Medicine. She is particularly interested in examining weight trajectories during pregnancy to see how they may affect fetal outcomes. Her team’s current project also will likely include analysis to examine other variables like postpartum weight gain and adiposity characteristics of the baby.
Maya said the team hopes to have more to report at the American Diabetes Association conference in June next year.
Offer the Conversation
Using a GLP-1 for weight loss takes time, usually around 1 year to reach a plateau. Boots encouraged nonfertility providers to ask patients of reproductive age about their family plans as an opening.
“I hope for all primary care doctors and gynecologists, that with any patient of reproductive age, you should be bringing this up, asking, ‘Have you thought about having kids? Are you thinking about it soon?’ And if they say they are sometime in the near future, then you can say, ‘Is it OK if I bring up your weight?’ And you should ask permission.”
If the patient declines, it’s OK to bring it up again at a future visit.
“People with obesity have often experienced negative weight bias that impacts their care,” Jimenez said. “Treat obesity as a disease, not a personal failing. Ask permission to discuss weight with the patient beforehand. If they say no, respect that answer. This goes a long way in developing a positive relationship, so they return for care and may be willing to discuss later.”
When patients are open to the conversation, Boots suggests not focusing on the potential for poor outcomes, and instead perhaps saying, “If you’re thinking about having a baby in 5 years, optimizing your health now will not only make your pregnancy healthier, but your child healthier long-term.”
Discussing contraception plans remains important. People starting semaglutide or tirzepatide should use contraception other than oral birth control for 4 weeks while starting the medicine and for 4 weeks after each dose increase.
Boots said that the contraception conversation is particularly important because many people have come to deeply believe that they are infertile and, thus, may perhaps think contraception advice doesn’t apply to them. Maya hypothesized that behavioral changes following weight loss may also be a pathway toward pregnancy.
“Pregnancy while on GLP-1 RAs does happen. I always have a discussion about this possibility and contraception. This can sometimes be challenging for people with infertility to consider,” Jimenez said. “Explaining the risks, benefits, and unknowns can help. As the [Fertility and Sterility] paper describes, the limited data available has not shown increased fetal or maternal complications. We need more high quality data to better understand the impact of exposure or use around the time of conception and during pregnancy.”
It’s also important to introduce the idea to patients that they may someday need to come off the medications, such as when they are ready to have children, and how important lifestyle and behavioral changes will be at that time, Maya said.
“We do know what the alternative is, and we do know what the risks of obesity are,” she said. “So, it’s a tug and pull. We’re not starting off with healthy. We’re starting off with a disease that is physically and emotionally very difficult for the patient, especially when it starts in childhood.”

Postpartum Depression Common After Cesarean Delivery
TOPLINE:
About one in six women experience symptoms of postpartum depression (PPD) 2 months after cesarean delivery, with certain obstetric factors such as emergency cesarean delivery before labor, cesarean delivery after labor induction, lack of social support in the operating room, and severe postoperative pain influencing the risk.
METHODOLOGY:
- Researchers conducted a prospective ancillary cohort study of the Tranexamic Acid for Preventing Postpartum Hemorrhage after Cesarean Delivery (TRAAP2) trial to examine the prevalence of PPD 2 months after cesarean delivery and associated risk factors.
- A total of 2793 women (median age, 33.5 years) were included who had a cesarean delivery at 34 or more weeks of gestation; they completed the Edinburgh Postnatal Depression Scale (EPDS), a self-administered questionnaire, at 2 months after delivery.
- Information about the cesarean delivery, postpartum blood loss, immediate postpartum period, psychiatric history, and memories of delivery and postoperative pain were prospectively collected.
- Medical records were used to obtain details about characteristics of patients; 5.0% had a psychiatric history (2.4% composed of depression).
- The main endpoint was a positive screening for symptoms consistent with this depression — defined as a PPD diagnosis — 2 months after caesarian delivery, with an EPDS score of 13 or higher.
TAKEAWAY:
- The prevalence of a provisional PPD diagnosis at 2 months after cesarean delivery was 16.4% (95% CI, 14.9-18.0) with an EPDS score of 13 or higher and was 23.1% (95% CI, 21.4-24.9%) with a cutoff value of 11 or higher.
- Women who had an emergency cesarean delivery before labor had a higher risk for PPD than those who had a normal cesarean delivery before labor started (adjusted odds ratio [aOR], 1.70; 95% CI, 1.15-2.50); women who had started labor after induction but then had a cesarean delivery also had a higher risk for PPD than those who had a cesarean delivery before going into labor (aOR, 1.36; 95% CI, 1.03-1.84).
- Severe pain during the postpartum stay (aOR, 1.73; 95% CI, 1.32-2.26) and bad memories of delivery (aOR, 1.67; 95% CI, 1.14-2.45) were also risk factors for PPD.
- However, women who had social support in the operating room showed a 27% lower risk for PPD (P = .02).
IN PRACTICE:
“Identifying subgroups of women at risk for PPD based on aspects of their obstetric experience could help to screen for women who might benefit from early screening and interventions,” the authors wrote.
SOURCE:
This study was led by Alizée Froeliger, MD, MPH, of the Department of Obstetrics and Gynecology at Bordeaux University Hospital in France, and was published online in American Journal of Obstetrics & Gynecology.
LIMITATIONS:
The study population was derived from a randomized controlled trial, which may have underestimated the prevalence of PPD. The use of a self-administered questionnaire for PPD screening may not have provided a definitive diagnosis. Moreover, this study did not assess the prevalence of depressive symptoms during pregnancy.
DISCLOSURES:
The TRAAP2 trial was supported by a grant from the French Ministry of Health under its Clinical Research Hospital Program. One author reported carrying out consultancy work and lecturing for Ferring Laboratories, GlaxoSmithKline, and other pharmaceutical companies.

Treating Obesity May Reduce Pelvic Organ Prolapse Risk
TOPLINE:
People with central obesity (CO), characterized by excess fat around the abdomen, are at a greater risk for pelvic organ prolapse (POP), particularly those who are younger than 60 years or without a history of hysterectomy. Also, women who have overweight but do not have CO are at greater risk.
METHODOLOGY:
- Researchers conducted a prospective cohort study to estimate the association between CO and general obesity and the risk for POP in individuals using the UK Biobank.
- A total of 251,143 participants (median age, 57 years) without preexisting POP were included, of whom 60.9% were postmenopausal and 17.2% had undergone hysterectomy before enrollment.
- Participants were followed for a median duration of 13.8 years, and POP cases were identified using International Classification of Diseases, 10th Revision (ICD-10) codes.
- Waist circumference, height, and body weight were measured at enrollment for the calculation of waist/height ratio and body mass index (BMI); CO was defined as a waist/height ratio ≥ 0.5.
- The relative risk of POP for the various combinations of waist/height ratio and BMI was evaluated against the reference group (waist/height ratio < 0.5; BMI < 25) using Cox proportional hazards models.
TAKEAWAY:
- During the follow-up period, 9781 cases of POP were identified, of which 71.2% occurred in a single pelvic compartment.
- Around 21.7% of all POP cases were attributable to CO; 2% were attributable to being overweight without CO.
- The risk for POP was 48% higher in individuals with CO regardless of BMI (hazard ratio [HR], 1.48; 95% CI, 1.41-1.56) and 23% higher in those who had overweight without CO (HR, 1.23; 95% CI, 1.14-1.34).
- The association between POP and CO was further strengthened in individuals who were younger than 60 years and those without a history of hysterectomy.
IN PRACTICE:
“We found that waist/height ratio combined with BMI could help differentiate individuals with varying risks of prolapse more accurately. Among individuals within the same BMI category, waist/height ratio can vary, with those having a higher ratio generally facing a greater risk of POP, compared with those with a normal ratio. Therefore, they should not be grouped together based solely on a single measure of obesity. In addition, this combination can help identify more individuals at high risk for POP, compared with using either alone,” the study authors wrote.
SOURCE:
This study was led by Keyi Si, PhD, of Tongji University in Shanghai, China, and was published online in Obstetrics & Gynecology.
LIMITATIONS:
Differences in healthcare-seeking behavior could have biased the association between obesity and risk for POP, as individuals with obesity may have been less likely to notice or report symptoms of POP. The diagnosis of POP was according to ICD-10 codes rather than physical examination, which may have affected accuracy. Other limitations included missing data on delivery mode and history of constipation.
DISCLOSURES:
This study was supported by grants from the National Natural Science Foundation of China, the Science and Technology Commission of Shanghai Municipality, the Shanghai Hospital Development Center, and the Shanghai First Maternity and Infant Hospital. The authors reported no conflicts of interest.
