RESUMEN

BACKGROUND: Women with obesity and infertility are counseled to lose weight prior to conception and infertility treatment to improve pregnancy rates and birth outcomes, although confirmatory evidence from randomized trials is lacking. We assessed whether a preconception intensive lifestyle intervention with acute weight loss is superior to a weight neutral intervention at achieving a healthy live birth. METHODS AND FINDINGS: In this open-label, randomized controlled study (FIT-PLESE), 379 women with obesity (BMI ≥ 30 kg/m2) and unexplained infertility were randomly assigned in a 1:1 ratio to 2 preconception lifestyle modification groups lasting 16 weeks, between July 2015 and July 2018 (final follow-up September 2019) followed by infertility therapy. The primary outcome was the healthy live birth (term infant of normal weight without major anomalies) incidence. This was conducted at 9 academic health centers across the United States. The intensive group underwent increased physical activity and weight loss (target 7%) through meal replacements and medication (Orlistat) compared to a standard group with increased physical activity alone without weight loss. This was followed by standardized empiric infertility treatment consisting of 3 cycles of ovarian stimulation/intrauterine insemination. Outcomes of any resulting pregnancy were tracked. Among 191 women randomized to standard lifestyle group, 40 dropped out of the study before conception; among 188 women randomized to intensive lifestyle group, 31 dropped out of the study before conception. All the randomized women were included in the intent-to-treat analysis for primary outcome of a healthy live birth. There were no significant differences in the incidence of healthy live births [standard 29/191(15.2%), intensive 23/188(12.2%), rate ratio 0.81 (0.48 to 1.34), P = 0.40]. Intensive had significant weight loss compared to standard (-6.6 ± 5.4% versus -0.3 ± 3.2%, P < 0.001). There were improvements in metabolic health, including a marked decrease in incidence of the metabolic syndrome (baseline to 16 weeks: standard: 53.6% to 49.4%, intensive 52.8% to 32.2%, P = 0.003). Gastrointestinal side effects were significantly more common in intensive. There was a higher, but nonsignificant, first trimester pregnancy loss in the intensive group (33.3% versus 23.7% in standard, 95% rate ratio 1.40, 95% confidence interval [CI]: 0.79 to 2.50). The main limitations of the study are the limited power of the study to detect rare complications and the design difficulty in finding an adequate time matched control intervention, as the standard exercise intervention may have potentially been helpful or harmful. CONCLUSIONS: A preconception intensive lifestyle intervention for weight loss did not improve fertility or birth outcomes compared to an exercise intervention without targeted weight loss. Improvement in metabolic health may not translate into improved female fecundity. TRIAL REGISTRATION: ClinicalTrials.gov NCT02432209.

RESUMEN

Importance: Women with an early nonviable pregnancy of unknown location are at high risk of ectopic pregnancy and its inherent morbidity and mortality. Successful and timely resolution of the gestation, while minimizing unscheduled interventions, are important priorities. Objective: To determine if active management is more effective in achieving pregnancy resolution than expectant management and whether the use of empirical methotrexate is noninferior to uterine evacuation followed by methotrexate if needed. Design, Setting, and Participants: This multicenter randomized clinical trial recruited 255 hemodynamically stable women with a diagnosed persisting pregnancy of unknown location between July 25, 2014, and June 4, 2019, in 12 medical centers in the United States (final follow up, August 19, 2019). Interventions: Eligible patients were randomized in a 1:1:1 ratio to expectant management (n = 86), active management with uterine evacuation followed by methotrexate if needed (n = 87), or active management with empirical methotrexate using a 2-dose protocol (n = 82). Main Outcomes and Measures: The primary outcome was successful resolution of the pregnancy without change from initial strategy. The primary hypothesis tested for superiority of the active groups combined vs expectant management, and a secondary hypothesis tested for noninferiority of empirical methotrexate compared with uterine evacuation with methotrexate as needed using a noninferiority margin of -12%. Results: Among 255 patients who were randomized (median age, 31 years; interquartile range, 27-36 years), 253 (99.2%) completed the trial. Ninety-nine patients (39%) declined their randomized allocation (26.7% declined expectant management, 48.3% declined uterine evacuation, and 41.5% declined empirical methotrexate) and crossed over to a different group. Compared with patients randomized to receive expectant management (n = 86), women randomized to receive active management (n = 169) were significantly more likely to experience successful pregnancy resolution without change in their initial management strategy (51.5% vs 36.0%; difference, 15.4% [95% CI, 2.8% to 28.1%]; rate ratio, 1.43 [95% CI, 1.04 to 1.96]). Among active management strategies, empirical methotrexate was noninferior to uterine evacuation followed by methotrexate if needed with regard to successful pregnancy resolution without change in management strategy (54.9% vs 48.3%; difference, 6.6% [1-sided 97.5% CI, -8.4% to ∞]). The most common adverse event was vaginal bleeding for all of the 3 management groups (44.2%-52.9%). Conclusions and Relevance: Among patients with a persisting pregnancy of unknown location, patients randomized to receive active management, compared with those randomized to receive expectant management, more frequently achieved successful pregnancy resolution without change from the initial management strategy. The substantial crossover between groups should be considered when interpreting the results. Trial Registration: ClinicalTrials.gov Identifier: NCT02152696.

RESUMEN

CONTEXT: Sleep plays important roles in metabolic and reproductive function, and polycystic ovary syndrome (PCOS) is associated with sleep disturbances, including increased prevalence of obstructive sleep apnea. OBJECTIVE: We sought to evaluate sleep parameters in infertile women with PCOS compared with women with unexplained infertility (UI) and identify risk factors for disturbed sleep. METHODS: At private and academic ambulatory gynecology and infertility practices, we evaluated a prospective cohort of women diagnosed with PCOS or UI from 2 randomized clinical trials. We included 1603 infertile women enrolled in 2 concurrent randomized clinical trials. The main outcome measures were self-reported sleep measures. RESULTS: Sleep duration <6 hours (6.1% vs 2.7%; P < .001), habitual snoring (37.8% vs 19.0%; P < .001), and clinical sleepiness (12.0% vs 8.6%; P < .026) were more common in women with PCOS than those with UI. After adjusting for covariates, PCOS and elevated fasting insulin were associated (P = .010) with clinical symptoms of obstructive sleep apnea (OSA) diagnosis, whereas PCOS, elevated insulin (P = .003), WC >88 cm (P = .003), and current smoking (P = .012) were associated with habitual snoring. Clinical depression score (P < .001) and PCOS diagnosis (P = .002) were associated with perceived daytime sleepiness. Short sleep duration and clinical symptoms of OSA were not associated with conception and live birth rates. CONCLUSION: Infertile women with PCOS more commonly report sleep disturbances than those with UI. Markers of insulin resistance are associated with previous diagnosis of OSA, habitual snoring, and short sleep duration. The presence of clinical symptoms of OSA or short sleep duration does not affect fertility treatment response.

RESUMEN

Maternal mortality and severe maternal morbidity are urgent issues in the United States. It is important to establish priority areas to address these public health crises. On April 8, 2019, and May 2 to 3, 2019, the Eunice Kennedy Shriver National Institute of Child Health and Human Development organized and invited experts with varied perspectives to 2 meetings, a community engagement forum and a scientific workshop, to discuss underlying themes involved in the rising incidence of maternal mortality in the United States. Experts from diverse disciplines reviewed current data, ongoing activities, and identified research gaps focused on data measurement and reporting, obstetrical and health system factors, social determinants and disparities, and the community perspective and engagement. Key scientific opportunities to reduce maternal mortality and severe maternal morbidity include improved data quality and measurement, understanding the populations affected as well as the numerous etiologies, clinical research to confirm preventive and interventional strategies, and engagement of community participation in research that will lead to the reduction of maternal mortality in the United States. This article provides a summary of the workshop presentations and discussions.

RESUMEN

OBJECTIVE: To study the development of children conceived from non-IVF infertility treatments consisting of gonadotropins, clomiphene, or letrozole. DESIGN: Prospective cohort study. SETTING: U.S. academic health centers. PATIENT(S): Children of women with polycystic ovary syndrome who conceived with letrozole (LTZ) or clomiphene (CC) in the PPCOS II study or women with unexplained infertility (AMIGOS study) who conceived with LTZ, CC, or gonadotropin (GN). INTERVENTION(S): Longitudinal annual follow-up from birth to age 3. MAIN OUTCOME MEASURE(S): Scores from Ages and Stages Developmental Questionnaire (ASQ), MacArthur-Bates Communicative Development Inventory (MCDI), and annual growth. RESULT(S): One hundred eighty-five children from 160 families participated in at least one follow-up evaluation from the two infertility trials. Most multiple gestations in the follow-up study resulted from GN treatment (n = 14) followed by CC (n = 6) and LTZ (n = 3). There were no significant differences among the three groups at any time point with respect to abnormal scores on the ASQ. On the MCDI Words and Gestures, the LTZ group scored significantly higher than the GN group for most items (phrases, early gestures, later gestures, and total gestures). Children in the CC group scored significantly higher than the GN group for the later gestures and total gestures items. CONCLUSION(S): Differences in growth and cognitive developmental rates among children conceived with first-line infertility therapies, including LTZ, are relatively minor and likely due to differences in multiple pregnancy rates.

RESUMEN

OBJECTIVE: To determine whether antioxidants improve male fertility, as measured by semen parameters and DNA fragmentation at 3 months and pregnancy resulting in live birth after up to 6 months of treatment, among couples with male factor infertility. DESIGN: Multicenter, double-blind, randomized, placebo-controlled trial with an internal pilot study. SETTING: Nine fertility centers in the United States from December 2015 to December 2018. PATIENT(S): Men (N = 174) with sperm concentration ≤15 million/mL, motility ≤40%, normal morphology ≤4%, or DNA fragmentation >25%, and female partners who were ovulatory, ≤40 years old, and had documented tubal patency. INTERVENTION(S): Males randomly assigned to receive an antioxidant formulation (n = 85) containing 500 mg of vitamin C, 400 mg of vitamin E, 0.20 mg of selenium, 1,000 mg of l-carnitine, 20 mg of zinc, 1,000 µg of folic acid, 10 mg of lycopene daily, or placebo (n = 86). Treatment lasted for a minimum of 3 months and maximum of 6 months, and couples attempted to conceive naturally during the first 3 months and with clomiphene citrate with intrauterine insemination of the female partner in months 4 through 6. MAIN OUTCOME MEASURE(S): Primary outcome was live birth; secondary outcomes included pregnancy within 6 months of treatment. For the internal pilot, the primary outcomes were semen parameters and sperm DNA fragmentation index after 3 months of treatment. RESULT(S): In the Males, Antioxidants, and Infertility (MOXI) study, after 3 months of treatment, the change in sperm concentration differed between the antioxidant group (median -4.0 [interquartile range-12.0, 5.7] million/mL) and placebo group (+2.4 [-9.0, 15.5] million/mL). However, there were no statistically significant differences between the two groups for changes in sperm morphology, motility, or DNA fragmentation. Among the 66 oligospermic men at randomization, sperm concentration did not differ at 3 months between the antioxidant and control groups: 8.5 (4.8, 15.0) million/mL versus 15.0 (6.0, 24.0) million/mL. Of the 75 asthenospermic men, motility did not differ at 3 months: 34% ± 16.3% versus 36.4% ± 15.8%. Among the 44 men with high DNA fragmentation, DNA fragmentation did not differ at 3 months: 29.5% (21.6%, 36.5%) versus 28.0% (20.6%, 36.4%). In the entire cohort, cumulative live birth did not differ at 6 months between the antioxidant and placebo groups: 15% versus 24%. CONCLUSION(S): Antioxidants do not improve semen parameters or DNA integrity among men with male factor infertility. Although limited by sample size, this study suggests that antioxidant treatment of the male partner does not improve in vivo pregnancy or live-birth rates. CLINICAL TRIAL REGISTRATION NUMBER: NCT02421887.

RESUMEN

OBJECTIVE: To study whether there is a difference in the prevalence of non-cavity-distorting uterine fibroids between infertile patients with polycystic ovary syndrome (PCOS) and those with unexplained infertility (UI). DESIGN: A secondary analysis of data from three randomized clinical trials. SETTING: Academic health centers. PATIENT(S): A total of 2,249 patients with normal uterine cavities. INTERVENTIONS(S): None. MAIN OUTCOME MEASURE(S): The presence or absence of non-cavity-distorting fibroids. RESULT(S): Compared with women with UI, those with PCOS were younger, had a higher body mass index, and were more likely to be Hispanic or African American, with a lower percentage of previous conception and live birth, a higher percentage of current smokers, a lower percentage of current alcohol users, and higher total testosterone, fasting insulin, and homeostasis-model-assessment insulin resistance. The prevalence of women with non-cavity-distorting uterine fibroids was lower in women with PCOS than in those with UI (6.7% vs. 12.4%); this result held after patients were divided into Black and non-Black or into three different body mass index groups. After adjustment for all the other variables in the final model, patients with PCOS had a significantly lower prevalence of fibroids than those with UI (odds ratio 0.54). No differences in the prevalence of non-cavity-distorting fibroids with any dimensions ≥4 cm or the volume of the largest fibroid was found between the two groups. CONCLUSION(S): A lower prevalence of non-cavity-distorting uterine fibroids was found in infertile women with PCOS than in those with UI.

RESUMEN

BACKGROUND/AIMS: Timely review of research protocols by institutional review boards leads to more rapid initiation of clinical trials, which is critical to expeditious translation from bench to bedside. This observational study examined the impact of a single institutional review board on time and efforts required to initiate clinical trials by the National Institute of Child Health and Human Development Cooperative Reproductive Medicine Network. METHODS: Collection of data from the same six main clinical sites for three current clinical trials and two past clinical trials, including time from institutional review board submission to approval, pages submitted, consent form length, number of required attachments, other regulatory requirements, order of review at central or local sites, and language in documents at individual participating sites. Results from two past clinical trials were also included. RESULTS: While time required for actual institutional review board submission's review and initial approval was reduced with use of a single institutional review board for multicenter trials (from a mean of 66.7-24.0 days), total time was increased (to a mean of 111.2 or 123.3 days). In addition to single institutional review board approval, all institutions required local approval of some components (commonly consent language and use of local language), which varied considerably. The single institutional review board relied on local institutions for adding or removing personnel, conflict of interest review, and auditing of activities. CONCLUSION: A single institutional review board reduced time for initial review and approval of protocols and informed consents, although time for the entire process was increased, as individual institutions retained oversight of components of required regulatory review. In order to best achieve the National Institute of Health's goals for improved efficiency in initiation and conduct of multisite clinical research, greater coordination with local institutional review boards is key to streamlining and accelerating initiation of multisite clinical research.

RESUMEN

OBJECTIVE: Pregnancy of unknown location (PUL) is not a diagnosis but a transient state used to classify a woman when she has a positive pregnancy test without definitive evidence of an intra-uterine or extra-uterine pregnancy on transvaginal ultrasonography. Management of a persisting PUL varies substantially, including expectant or active management. Active management can include uterine cavity evacuation or systemic administration of methotrexate. To date, no consensus has been reached on whether either management strategy is superior or non-inferior to the other. DESIGN: Randomized controlled trial. SETTING: Academic medical centers. PATIENTS: We plan to randomize 276 persisting PUL-diagnosed women who are 18 years or older from Reproductive Medicine Network clinics and additional interested sites, all patients will be followed for 2 years for fertility and patient satisfaction outcomes. INTERVENTIONS: Randomization will be 1:1:1 ratio between expectant management, uterine evacuation and empiric use of methotrexate. After randomization to initial management plan, all patients will be followed by their clinicians until resolution of the PUL. The clinician will determine whether there is a change in management, based on clinical symptoms, and/or serial human chorionic gonadotropin (hCG) concentrations and/or additional ultrasonography. MAIN OUTCOME: The primary outcome measure in each of the 3 treatment arms is the uneventful clinical resolution of a persistent PUL without change from the initial management strategy. Secondary outcome measures include: number of ruptured ectopic pregnancies, number and type of re-interventions (additional methotrexate injections or surgical procedures), treatment complications, adverse events, number of visits, time to resolution, patient satisfaction, and future fertility. CONCLUSION: This multicenter randomized controlled trial will provide guidance for evidence-based management for women who have persisting pregnancy of unknown location.

RESUMEN

PURPOSE: To compare saline infusion sonohysterography (SIS) versus hysterosalpingogram (HSG) for confirmation of tubal patency. METHODS: Secondary analysis of a randomized controlled trial, Pregnancy in Polycystic Ovary Syndrome II (PPCOS II). Seven hundred fifty infertile women (18-40 years old) with polycystic ovary syndrome (PCOS) were randomized to up to 5 cycles of letrozole or clomiphene citrate. Prior to enrollment, tubal patency was determined by HSG, the presence of free fluid in the pelvis on SIS, laparoscopy, or recent intrauterine pregnancy. Logistic regression was conducted in patients who ovulated with clinical pregnancy as the outcome and HSG or SIS as the key independent variable. RESULTS: Among women who ovulated, 414 (66.9%) had tubal patency confirmed by SIS and 187 (30.2%) had at least one tube patent on HSG. Multivariable analysis indicated that choice of HSG versus SIS did not have a significant relationship on likelihood of clinical pregnancy, after adjustment for treatment arm, BMI, duration of infertility, smoking, and education (OR 1.14, 95% CI 0.77, 1.67, P = 0.52). Ectopic pregnancy occurred more often in women who had tubal patency confirmed by HSG compared to SIS (2.8% versus 0.6%, P = 0.02). CONCLUSIONS: In this large cohort of women with PCOS, there was no significant difference in clinical pregnancy rate between women who had tubal patency confirmed by HSG versus SIS. SIS is an acceptable imaging modality for assessment of tubal patency in this population.

RESUMEN

STUDY QUESTION: Among infertile women undergoing ovarian stimulation, is allostatic load (AL), a measure of chronic physiological stress, associated with subsequent fertility and pregnancy outcomes? SUMMARY ANSWER: AL at baseline was not associated with conception, spontaneous abortion or live birth, however, it was significantly associated with increased odds of pre-eclampsia and preterm birth among women who had a live birth in the study. WHAT IS KNOWN ALREADY: Several studies have linked AL during pregnancy to adverse outcomes including preterm birth and pre-eclampsia, hypothesizing that it may contribute to well-documented disparities in pregnancy and birth outcomes. However, AL biomarkers change over the course of pregnancy, raising questions as to whether gestational AL assessment is a valid measure of cumulative physiologic stress starting long before pregnancy. To better understand how AL may impact reproductive outcomes, AL measurement in the non-pregnant state (i.e. prior to conception) is needed. STUDY DESIGN, SIZE, DURATION: A secondary data analysis based on data from 836 women who participated in Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS), a multi-center, randomized clinical trial of ovarian stimulation conducted from 2011 to 2014. PARTICIPANTS/MATERIALS, SETTING, METHODS: Ovulatory women with unexplained infertility (ages 18-40) were enrolled and at baseline, biological and anthropometric measures were collected. AL scores were calculated as a composite of the following baseline variables determined a priori: BMI, waist-to-hip ratio, systolic blood pressure, diastolic blood pressure, dehydroepiandrosterone sulfate, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, C-reactive protein and HOMA score. Participants received ovarian stimulation for up to four cycles and if they conceived, were followed throughout pregnancy. We fit multi-variable logistic regression models examining AL (one-tailed and two-tailed) in relation to the following reproductive outcomes: conception, spontaneous abortion, live birth, pre-eclampsia, preterm birth and low birthweight. MAIN RESULTS AND THE ROLE OF CHANCE: Adjusting for covariates, a unit increase in two-tailed AL score was associated with 62% increased odds of pre-eclampsia (OR: 1.62, 95% CI: 1.14, 2.38) 44% increased odds of preterm birth (OR: 1.44, 95% CI: 1.02, 2.08), and 39% increased odds of low birthweight (OR: 1.39, 95% CI: 0.99, 1.97). The relationship between AL and preterm birth was mediated by pre-eclampsia (P = 0.0003). In one-tailed AL analyses, associations were similar, but slightly attenuated. AL was not associated with fertility outcomes (conception, spontaneous abortion, live birth). LIMITATIONS, REASONS FOR CAUTION: Results may not be generalizable to fertile women who conceive naturally or women with other types of infertility. Comparisons to previous, related work are difficult because variables included in AL composite measures vary across studies. AL may be indicative of overall poor health, rather than being specific to chronic physiological stress. WIDER IMPLICATIONS OF THE FINDINGS: Our results suggest that chronic physiological stress may not impact success of ovarian stimulation, however, they confirm and extend previous work suggesting that AL is associated with adverse pregnancy outcomes. Physiological dysregulation due to chronic stress has been proposed as a possible mechanism underlying disparities in birth outcomes, which are currently poorly understood. Assessing biomarkers of physiological dysregulation pre-conception or in early pregnancy, may help to identify women at risk of adverse pregnancy outcomes, particularly pre-eclampsia.

RESUMEN

Context: Women with polycystic ovary syndrome (PCOS) have increased risk for pregnancy complications, possibly related to pre-existing obesity and excessive gestational weight gain (GWG). Objectives: To assess the contributions of diagnosis and preconception weight on GWG and perinatal outcomes. Research Design and Methods: Prospective cohort study of singleton pregnancies in PCOS (n = 164) and ovulatory controls (n = 176) from infertility treatment. Main Outcome Measures: GWG, birthweight, pregnancy complications. Results: From preconception baseline, normal-weight women with PCOS gained 2.3 pounds more during the first trimester (95% CI, 0.3 to 4.3; P = 0.02), and by the end of the second trimester, 4.2 pounds more than controls (95% CI, 0.7 to 7.7; P = 0.02). Women who were overweight with PCOS gained significantly more weight than did controls by the end of the second trimester (5.2 pounds; 95% CI, 0.2 to 10.2; P = 0.04), whereas women with obesity and PCOS and control women had similar weight gain throughout pregnancy. Within normal-weight, overweight, and obese groups, prevalence of pre-eclampsia and gestational diabetes did not differ between the PCOS and control groups, nor was there a difference in birthweight. Preconception body mass index (BMI) was significantly associated with GWG; for every 1-kg/m2 increase in preconception BMI, GWG decreased by 0.62 pounds (95% CI, -0.85 to -0.40; P < 0.001). Conclusions: Women with PCOS who are of normal weight or are overweight before conception experience more GWG than do ovulatory controls. Within normal-weight, overweight, and obese groups, rates of perinatal complications do not significantly differ between women with PCOS and controls. Preconception BMI is the strongest predictor of GWG.

RESUMEN

OBJECTIVE: To test the hypothesis that insulin resistance is associated with depression risk in polycystic ovary syndrome (PCOS). DESIGN: Secondary analysis of data from a multicenter randomized trial. SETTING: Multicenter university-based clinical practices. PATIENT(S): Seven hundred thirty-eight women with PCOS by modified Rotterdam criteria seeking pregnancy enrolled in a randomized clinical trial comparing clomiphene citrate versus letrozole. INTERVENTION(S): The Primary Care Evaluation of Mental Disorders Patient Health Questionnaire was self-administered to identify depression using a validated algorithm at enrollment. Demographic and anthropometric data were collected, and serum assays were performed. Insulin resistance was estimated using the homeostatic model of insulin resistance (HOMA-IR), with a cutoff of >2.2 considered abnormal. MAIN OUTCOME MEASURE(S): Demographic, endocrine, and metabolic parameters associated with depression. RESULT(S): In a univariate logistic regression analysis, elevated HOMA-IR was associated with 2.3-fold increased odds of depression (odds ratio [OR] = 2.32; 95% confidence interval [CI], 1.28-4.21). This association remained significant after controlling for age and body mass index (adjusted OR [aOR] = 2.23; 95% CI, 1.11-4.46) and in a model including additional potential confounders (aOR = 2.03; 95% CI, 1.00-4.16). CONCLUSION(S): Insulin resistance has a strong and independent association with depression in PCOS and may serve as a physiologic mediator. Our findings corroborate a growing body of evidence linking insulin resistance to depressed mood. The association between insulin resistance and depressed mood warrants further investigation to elucidate mechanisms and identify potential therapeutic targets.

RESUMEN

Context: Adequate luteal phase progesterone exposure is necessary to induce endometrial changes required for a successful pregnancy outcome. The relationship between low midluteal progesterone concentration and the outcome of live birth in ovarian stimulation with intrauterine insemination (OS-IUI) treatments is not defined. Objective: To determine the level of midluteal progesterone portending a low chance of live birth after OS-IUI in couples with unexplained infertility. Design and Setting: Secondary analyses of data from a prospective, randomized, multicenter clinical trial that determined pregnancy outcomes following OS-IUI with clomiphene citrate, letrozole, or gonadotropins for couples with unexplained infertility. Participants: Couples (n = 900) underwent 2376 OS-IUI cycles during the Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation clinical trial. Main Outcome Measures: Live birth as it relates to midluteal progesterone level and thresholds below which no live births occur by treatment group. Results: Thresholds for non-live birth cycles were similar for clomiphene (14.4 ng/mL) and letrozole (13.1 ng/mL) yet were lower for gonadotropin (4.3 ng/mL) treatments. A midluteal progesterone level >10th percentile specific for each treatment group independently was associated with greater odds for a live birth in all OS-IUI cycles (adjusted OR: 2.17; 95% CI: 1.05, 4.48). Conclusions: During OS-IUI, a low midluteal progesterone level was associated with a low probability of live birth. Thresholds differed by medication, with the lowest threshold for gonadotropin. Several pathophysiologic mechanisms may account for low progesterone levels. Refinement of the predictive range associated with particular ovarian stimulation medications during treatment of unexplained infertility may improve accuracy.

RESUMEN

OBJECTIVE: To determine if maternal major depression (MD), antidepressant use, or paternal MD are associated with pregnancy outcomes after non-IVF fertility treatments. DESIGN: Cohort study. SETTING: Clinics. PATIENT(S): Participants in two randomized trials: PPCOS II (clomiphene citrate versus letrozole for polycystic ovary syndrome), and AMIGOS (gonadotropins versus clomiphene citrate versus letrozole for unexplained infertility). INTERVENTION(S): Female and male partners completed the Patient Health Questionnaire (PHQ-9). Female medication use was collected. PHQ-9 score ≥10 was used to define currently active MD. MAIN OUTCOME MEASURE(S): Primary outcome: live birth. SECONDARY OUTCOMES: pregnancy, first-trimester miscarriage. Poisson regression models were used to determine relative risks after adjusting for age, race, income, months trying to conceive, smoking, and study (PPCOS II versus AMIGOS). RESULT(S): Data for 1,650 women and 1,608 men were included. Among women not using an antidepressant, the presence of currently active MD was not associated with poorer fertility outcomes (live birth, miscarriage), but rather was associated with a slightly increased likelihood of pregnancy. Maternal antidepressant use (n = 90) was associated with increased risk of miscarriage, and male partners with currently active MD were less likely to achieve conception. CONCLUSION(S): Currently active MD in the female partner does not negatively affect non-IVF treatment outcomes; however, currently active MD in the male partner may lower the likelihood of pregnancy. Maternal antidepressant use is associated with first-trimester pregnancy loss, which may depend upon the type of antidepressant. CLINICAL TRIAL REGISTRATION NUMBERS: NCT00719186 and NCT01044862.

RESUMEN

OBJECTIVE: Endometriosis is a chronic, estrogen dependent condition that affects 5-10% of reproductive aged women and is associated with pelvic pain and infertility. As the approach to therapy shifts from surgical ablation to pharmacological control, a non-surgical mode of diagnosis would be desirable. The ENDOmarker study was designed by the NICHD Reproductive Medicine Network (RMN) to obtain well characterized and phenotyped bio specimens in a standardized fashion from women with and without endometriosis. DESIGN: Development of a diagnostic test. SETTING: Academic medical centers. PATIENTS: This study will enroll up to 500 participants, and follow them for up to 5 months. Included subjects are aged 18-44, scheduled to undergo gynecologic surgery (laparoscopy/laparotomy) for clinical reasons. INTERVENTIONS: Presence and stage of endometriosis (or its absence) is characterized by visual examination at the time of surgery. Subjects will undergo extensive clinical evaluation pre-operatively and at visits one and four months postoperatively. Endometrial biopsy, blood, urine and disease specific questionnaires will be collected at each visit. MAIN OUTCOME: Samples will be placed in a bio-repository to be used to validate and optimize the clinical use of genomic classifiers of the endometrium alone or in combination with serum cytokines as a non-surgical composite marker of endometriosis. CONCLUSION: This protocol can serve as a reference for objective collection of high quality bio specimens for discovery or validation of potential nonsurgical diagnosis of presence or severity of disease.
