RESUMO

CONTEXT: DNA damage/repair gene variants are associated with both primary ovarian insufficiency (POI) and cancer risk. OBJECTIVE: We hypothesized that a subset of women with POI and family members would have increased risk for cancer. DESIGN: Case-control population-based study using records from 1995-2022. SETTING: Two major Utah academic healthcare systems serving 85% of the state. SUBJECTS: Women with POI (n=613) were identified using ICD codes and reviewed for accuracy. Relatives were linked using the Utah Population Database. INTERVENTION: Cancer diagnoses were identified using the Utah Cancer Registry. MAIN OUTCOME MEASURES: The relative risk of cancer in women with POI and relatives was estimated by comparison to population rates. Whole genome sequencing was performed on a subset of women. RESULTS: Breast cancer was increased in women with POI (OR [95%CI] 2.20 [1.30, 3.47]; p=0.0023) and there was a nominally significant increase in ovarian cancer. Probands with POI were 36.5±4.3 years and 59.5±12.7 years when diagnosed with POI and cancer, respectively. Causal and candidate gene variants for cancer and POI were identified.Among second-degree relatives of these women, there was an increased risk of breast (1.28 [1.08, 1.52]; p=0.0078) and colon cancer (1.50 [1.14, 1.94]; p=0.0036). Prostate cancer was increased in first- (1.64 [1.18, 2.23]; p=0.0026), second- (1.54 [1.32, 1.79]; p<0.001), and third-degree relatives (1.33 [1.20, 1.48]; p<0.001). CONCLUSIONS: Data suggest common genetic risk for POI and reproductive cancers. Tools are needed to predict cancer risk in women with POI and potentially to counsel about risks of hormone replacement therapy.

RESUMO

Objective: To investigate the impact of chemotherapy on the uterus. Design: Cross-sectional pilot study. Setting: Single university fertility clinic. Patients: Twelve patients with a history of alkylating agent chemotherapy exposure after Hodgkin lymphoma (cancer) vs. 12 normally menstruating women (controls). Interventions: The inclusion criteria were age of 18-45 years and consent for endometrial biopsy. The exclusion criteria were the absence of the uterus, completed pelvic radiation, uterine or cervical cancer, and metastatic cancer. Each participant underwent endometrial biopsy and pelvic ultrasound. All study visits were conducted in the late proliferative phase of the menstrual cycle. Main Outcome Measures: Uterine volume, blood flow, endometrial thickness, histology, deoxyribonucleic acid methylation pattern, and relative ribonucleic acid (RNA) expression level during the same phase of the menstrual cycle. Results: In the study group, visits were conducted at a median of 31.5 (13.5-42.5) months after chemotherapy. The median uterine volume among cancer survivors was 36 (11.3-67) cm3, and that of the general population controls was 39 (13-54) cm3. On histologic examination, there were no cytologic or architectural atypia. The RNA-sequencing analysis revealed poor clustering of both control and treatment samples. However, we identified 3 differentially expressed genes on RNA-sequencing, but there was no concordance found among the differentially expressed genes and deoxyribonucleic acid methylation changes suggesting most likely false-positive results. Conclusions: Approximately 2.5 years after chemotherapy, a time at which several survivors of Hodgkin lymphoma may resume family-building, endometrial thickness and endometrial histology were not significantly affected by a history of alkylating agent chemotherapy exposure.

RESUMO

PURPOSE: The field of oncofertility has maintained an important focus on improving access, yet standardized practices are lacking. To assess how female cancer patients are provided oncofertility care, we sought to determine provider-level differences and whether there are physician or practice characteristics that predict these variations. METHODS: A cross-sectional survey was sent to SREI members. The survey included fifteen questions about physician practice characteristics and oncofertility cryopreservation protocols. Topics included ovarian stimulation protocols, fertilization techniques, stage of embryo cryopreservation, routine use of pre-implantation genetic testing for aneuploidy (PGT-A), and ovarian tissue cryopreservation (OTC). Statistical analyses assessed whether practice setting, geographic region, time in practice, and mandatory state insurance coverage had effects on cryopreservation protocols. RESULTS: A total of 141 (17%) from diverse REI practice backgrounds completed the survey. The median number of new female oncofertility consults per year was 30 (range 1 to 300). Providers in academic settings treated more patients (median 40 vs. 15, p < 0.001). Providers in academic settings more often use gonadotropin-releasing hormone agonists (85% vs. 52%, p < 0.001) and perform OTC (41% vs. 4%, p < 0.001). Providers in academic practices were less likely to perform intracytoplasmic sperm injection in every cycle (37% vs. 55%, p = 0.032) and less likely to usually advise PGT-A (21% vs. 36%, p = 0.001). Mandated state insurance coverage had no effect on oncofertility practices. CONCLUSION: Oncofertility practices vary among providers. Factors such as practice setting and region may affect the services provided. We do not yet know the best practices in oncofertility patients, and future research is needed.

RESUMO

OBJECTIVE: To define the live birth rates in a large, population-based study of the most common reproductive-age cancers in women. DESIGN: Retrospective cohort study. SETTING: Population-based study. PATIENTS: Female cancer patients diagnosed with cancer at age 18 years old or older between 1952-2014 (n = 17,952) were compared to fertility of non-cancer controls (n = 89,436). INTERVENTIONS: Live births in cancer survivors were compared with those in healthy, age-matched controls. Cases and controls were matched in the ratio of 5:1 for birth year, birthplace (Utah, yes/no), and follow-up time in Utah. MAIN OUTCOME MEASURE: Rate of at least one live birth, reported as an incidence rate ratio (IRR). RESULTS: Of all cancer survivors, 3,127 (17.4%) had at least 1 live birth after treatment in comparison to 19,405 healthy, age-matched controls (21.7%) with the same amount of time exposure for attempting pregnancy. Breast cancer was the most common cancer type (23.1% of patients in cohort). Compared with age-matched, healthy controls, IRR of live birth was 0.69 (95% confidence interval [CI], 0.67-0.70) for all cancer types, 0.25 (95% CI, 0.20-0.33) for leukemia, 0.40 (95% CI, 0.28-0.59) for gastrointestinal cancers, 0.44 (95% CI, 0.41-0.48) for breast cancer, 0.53 (95% CI, 0.47-0.59) for central nervous system cancers, and 0.57 (95% CI, 0.44-0.73) for soft tissue cancers. With all cancer types stratified by age at diagnosis, IRR for live births in cancer survivors aged >41 years at diagnosis was 0.48 (95% CI, 0.44-0.52); IRR was 0.64 (95% CI, 0.61-0.67) in the group aged 31-40 years and 0.71 (95% CI, 0.69-0.74) in the group aged 18-30 years after their cancer treatment. CONCLUSIONS: Cancer and its treatment were associated with lower live birth rates when comparing women with cancer vs. age-matched, healthy controls.

RESUMO

The 5 principal reasons a patient may consider fertility preservation are: treatment for cancer that may affect fertility, treatment for nonmalignant medical conditions that may affect fertility, planned indications, planned gender-affirming hormone therapy or surgery, or in the setting of genetic conditions that may increase the risks of premature ovarian insufficiency or early menopause. This paper will focus on describing who may consider preserving their fertility, how to provide the best clinical evaluation of those seeking fertility preservation, and current and future fertility preservation techniques. Last, we will highlight a need to continue to expand access to fertility preservation technologies.

RESUMO

Diet, lifestyle, and psychosocial factors might influence fertility for men and women, although evidence is mixed, and couple-based approaches are needed for assessing associations with reproductive outcomes. The Impact of Diet, Exercise, and Lifestyle (IDEAL) on Fertility Study is a prospective cohort with contemporaneous detailed follow-up of female partners of men enrolled in the Folic Acid and Zinc Supplementation Trial studying couples seeking infertility treatment (2016-2019). Follow-up of men continued for 6 months, while female partners were followed for 9 months while attempting pregnancy and throughout any resulting pregnancy (up to 18 months). Longitudinal data on diet, physical activity (including measurement via wearable device), sleep, and stress were captured at multiple study visits during this follow-up. A subset of women (IDEALplus) also completed daily journals and a body fat assessment via dual-energy x-ray absorptiometry. IDEAL enrolled 920 women, and IDEALPlus enrolled 218. We demonstrated the ability to enroll women in a prospective cohort study contemporaneous to a partner-enrolled randomized trial. In combination with data collected on male partners, IDEAL data facilitates a couple-based approach to understanding associations between lifestyle factors and infertility treatment outcomes. We describe in detail the study design, recruitment, data collection, lessons learned, and baseline characteristics.

RESUMO

OBJECTIVE: To report a rare case of somatic mosaicism with a germline component of campomelic dysplasia in a woman undergoing in vitro fertilization with preimplantation genetic diagnosis (IVF-PGD). DESIGN: Case report. SETTING: Clinic. PATIENT(S): A 28-year old G2P0110 and her 34-year old husband had two previous pregnancies complicated by fetal campomelic dysplasia with suspected germline mosaic mutation. The couple, both phenotypically normal, underwent IVF-PGD to reduce their chances of transmission. None of the embryos could initially be determined to be disease free, because all embryos shared either a maternal or a paternal short tandem repeat haplotype with the products of conception from her last pregnancy. INTERVENTION(S): Peripheral-blood cytogenomic single-nucleotide polymorphism (SNP) microarray to identify the carrier of the mutation, and IVF-PGD to identify the disease-free embryo. MAIN OUTCOME MEASURE(S): Disease-free embryo. RESULT(S): Only one of the five euploid embryos was identified as disease free. CONCLUSION(S): A woman with suspected germline mosaicism for campomelic dysplasia was found to be a somatic mosaic with a germline component via a peripheral blood SNP microarray test. This identified her solitary disease-free embryo, which was transferred to her uterus but did not result in a viable pregnancy.

RESUMO

BACKGROUND: There is little known about the transgenerational effect of chemotherapy. For example, chemotherapy is known to decrease fecundity in women. But if women are able to have offspring after chemotherapy exposure, do these children also have decreased fecundity? METHODS: This study is a retrospective cohort study utilizing the Utah Population Database (UPDB), a comprehensive resource that links birth, medical, death and cancer records for individuals in the state of Utah. The male and female children (F1 generation) of chemotherapy-exposed women (F0 generation) were identified. The number of live births (F2 generation) to this F1 generation was compared to two sets of chemotherapy-unexposed, matched controls using conditional Poisson regression models (regression coefficient, 95% confidence interval, P-value). The first unexposed was established using the general population and the second unexposed was established using first cousins to the F1 generation. RESULTS: The exposed F1 individuals had 77.2% fewer children (-1.48; -2.51 to -0.70; p = 0.001) relative to the unexposed general population. F1 males had 86.9% fewer children (-2.03; -4.91 to -0.51; p = 0.005) and F1 females had 70.5% fewer children (-1.22; -2.40 to -0.36; p = 0.016). When comparing to their unexposed cousins, the F1 generation (both sexes combined) had 74.3% (-1.36; -2.82 to -0.29; p = 0.029) fewer children. CONCLUSION: The sons and daughters (F1 generation) of chemotherapy-exposed women have fewer live births when compared to both matched, unexposed general population and cousin controls. Chemotherapy may have a transgenerational effect in exposed women which needs further investigation.

RESUMO

PURPOSE: Poor semen quality is associated with reduced somatic health and increased cancer risk. Infertility and cancer are increasingly being linked by epidemiologists and basic scientists. We sought to identify semen parameters associated with an increased childhood cancer risk in the family members of subfertile men. MATERIALS AND METHODS: We performed a retrospective cohort study in men from the SHARE (Subfertility Heath and Assisted Reproduction) study who underwent semen analysis between 1994 and 2011. We used fertile population controls from the Utah Population Data Base. Our primary outcome was the risk of any childhood (18 years or younger) cancer in the siblings and cousins of men who underwent semen analysis compared to fertile, age matched controls. Cox proportional hazard regression models were used to test the association between semen quality and childhood cancer incidence. RESULTS: We selected 10,511 men with complete semen analysis and an equal number of fertile controls. These men had a total of 63,891 siblings and 327,753 cousins. A total of 170 and 958 childhood cancers were identified in siblings and cousins, respectively. The 3 most common cancers diagnosed in siblings were acute lymphoblastic leukemia in 37, brain cancer in 35 and Hodgkin lymphoma in 15. Oligozoospermia was associated with a twofold increased risk of any childhood cancer and a threefold increased risk of acute lymphoblastic leukemia in the siblings of subfertile men compared to fertile controls (HR 2.09, 95% CI 1.18-3.69 vs HR 3.07, 95% CI 1.11-8.46). CONCLUSIONS: Siblings of men with oligozoospermia are at increased risk for any-site cancer and acute lymphoblastic leukemia. This suggests a shared genetic/epigenetic insult or an environmental exposure that merits further investigation.

RESUMO

PURPOSE: The purpose of the study is to evaluate existing literature for possible associations between female infertility, infertility-associated diagnoses, and the following areas of disease: psychiatric disorders, breast cancer, ovarian cancer, endometrial cancer, cardiovascular disease, and metabolic dysfunction. METHODS: The design of the study is a literature review. The patients were women included in 26 selected studies due to a diagnosis of infertility or a reproductive disorder associated with infertility. This study has no interventions, and the main outcome measure is the association between female infertility or a related diagnosis and psychiatric disorders, breast cancer, ovarian cancer, endometrial cancer, cardiovascular disease, and metabolic dysfunction. RESULTS: Female infertility and related reproductive disorders may have ramifications for women beyond reproductive health. An analysis of publications shows that women with infertility had higher rates of psychiatric disorders and endometrial cancer than the general population [1-10]. Data is conflicting about whether infertile women are at increased risk for breast cancer and ovarian cancer [7, 8, 10-20]. A generalized diagnosis of infertility was not clearly associated with an increased risk of cardiovascular disease or metabolic dysfunction, but women with infertility related to polycystic ovarian syndrome (PCOS) do appear more likely to develop cardiovascular disease and metabolic disorders such as diabetes than the general population [16, 21-26]. CONCLUSIONS: Female infertility and associated diagnoses have overall health implications. Beyond treatment of patients' immediate reproductive needs, healthcare professionals must be aware of the broader health impact of specific causes of infertility in order to provide accurate counseling regarding long-term risk.

RESUMO

OBJECTIVE: To further characterize the association of male infertility with health risks by evaluating semen quality and cancer risk in family members. DESIGN: Retrospective, cohort study. SETTING: Not applicable. PATIENT(S): A total of 12,889 men undergoing SA and 12,889 fertile control subjects that had first-degree relative (FDR) data (n = 130,689) and 8,032 men with SA and 8,032 fertile control subjects with complete second-degree relative (SDR) data (n = 247,204) were identified through the UPDB. An equal number of fertile population control subjects were matched. INTERVENTIONS: None. MAIN OUTCOME MEASURE(S): Adult all-site, testicular, thyroid, breast, prostate, melanoma, bladder, ovarian, and kidney cancer diagnoses in FDRs and SDRs. RESULT(S): The FDRs of men with SA had a 52% increased risk of testicular cancer compared with the FDRs of fertile population control subjects. There was no significant difference in testicular cancer risk for the SDRs based on any of the semen parameters. The FDRs and SDRs of azoospermic men had a significantly increased risk of thyroid cancer compared with fertile population control subjects. CONCLUSION(S): These data suggest a link between male infertility and selected cancer risk in relatives. This highlights the possibilities of shared biologic mechanisms between the two diseases, exposure to environmental factors, and an increased level of genetic and/or epigenetic burden in subfertile men and their relatives that may be associated with risk of cancer.

RESUMO

STUDY QUESTION: Is sexual and/or physical abuse history associated with incident endometriosis diagnosis or other gynecologic disorders among premenopausal women undergoing diagnostic and/or therapeutic laparoscopy or laparotomy regardless of clinical indication? SUMMARY ANSWER: No association was observed between either a history of sexual or physical abuse and risk of endometriosis, ovarian cysts or fibroids; however, a history of physical abuse was associated with a higher likelihood of adhesions after taking into account important confounding and mediating factors. WHAT IS KNOWN ALREADY: Sexual and physical abuse may alter neuroendocrine-immune processes leading to a higher risk for endometriosis and other noninfectious gynecologic disorders, but few studies have assessed abuse history prior to diagnosis. STUDY DESIGN, SIZE, DURATION: The study population for these analyses includes the ENDO Study (2007-2009) operative cohort: 473 women, ages 18-44 years, who underwent a diagnostic and/or therapeutic laparoscopy or laparotomy at 1 of the 14 surgical centers located in Salt Lake City, UT, USA or San Francisco, CA, USA. Women with a history of surgically confirmed endometriosis were excluded. PARTICIPANTS/MATERIALS, SETTING AND METHODS: Prior to surgery, women completed standardized abuse questionnaires. Relative risk (RR) of incident endometriosis, uterine fibroids, adhesions or ovarian cysts by abuse history were estimated, adjusting for age, race/ethnicity, education, marital status, smoking, gravidity and recruitment site. We assessed whether a history of chronic pelvic pain, depression, or STIs explained any relationships via mediation analyses. MAIN RESULTS AND ROLE OF CHANCE: 43 and 39% of women reported experiencing sexual and physical abuse. No association was observed between either a history of sexual or physical abuse, versus no history, and risk of endometriosis (aRR: 1.00 [95% confidence interval (CI): 0.80-1.25]); aRR: 0.83 [95% CI: 0.65-1.06]), ovarian cysts (aRR: 0.67 [95% CI: 0.39-1.15]); aRR: 0.60 [95% CI: 0.34-1.09]) or fibroids (aRR: 1.25 [95% CI: 0.85-1.83]); aRR: 1.36 [95% CI: 0.92-2.01]). Conversely, a history of physical abuse, versus no history, was associated with higher risk of adhesions (aRR: 2.39 [95% CI: 1.18-4.85]). We found no indication that the effect of abuse on women's adhesion risk could be explained by a history of chronic pelvic pain, depression or STIs. LIMITATIONS, REASONS FOR CAUTION: Limitations to our study include inquiries on childhood physical but not sexual abuse. Additionally, we did not inquire about childhood or adulthood emotional support systems, found to buffer the negative impact of stress on gynecologic health. WIDER IMPLICATIONS OF THE FINDINGS: Abuse may be associated with some but not all gynecologic disorders with neuroendocrine-inflammatory origin. High prevalence of abuse reporting supports the need for care providers to screen for abuse and initiate appropriate follow-up. STUDY FUNDING/COMPETING INTERESTS: Supported by the Intramural Research Program, Eunice Kennedy Shriver National Institute of Child Health and Human Development (contracts NO1-DK-6-3428, NO1-DK-6-3427, and 10001406-02). The authors have no potential competing interests.

RESUMO

Multiple trace elements have estrogen receptor activity, but the association of these elements with uterine leiomyoma has not been defined. A cohort of 473 women aged 18-44 undergoing surgery for benign gynecologic indications provided whole blood and urine specimens for trace element analysis, which was performed by inductively coupled plasma mass spectrometry. Twenty elements were analyzed in blood and 3 in urine. The surgeon documented whether fibroids were present. Geometric mean concentrations were compared between women with and without fibroids, and logistic regression models were generated to assess the impact of the concentration of each trace element on the odds of fibroids. In multivariate regressions, odds of a fibroid diagnosis were higher with increased whole blood cadmium (AOR 1.44, 95% CI 1.02, 2.04) and lead (AOR 1.31 95% CI 1.02, 1.69), and urine cobalt (AOR 1.31, 95% CI 1.02, 1.70). Urinary cadmium and lead were not related to fibroid diagnosis. Increased exposure to trace elements may contribute to fibroid growth, and fibroids may serve as a reservoir for these elements. Differences between urinary and whole blood findings merit further investigation, as urinary cadmium has been considered a superior marker of exposure.

RESUMO

OBJECTIVE: We sought to identify risk factors for endometriosis and their consistency across study populations in the Endometriosis: Natural History, Diagnosis, and Outcomes (ENDO) Study. STUDY DESIGN: In this prospective matched, exposure cohort design, 495 women aged 18-44 years undergoing pelvic surgery (exposed to surgery, operative cohort) were compared to an age- and residence-matched population cohort of 131 women (unexposed to surgery, population cohort). Endometriosis was diagnosed visually at laparoscopy/laparotomy or by pelvic magnetic resonance imaging in the operative and population cohorts, respectively. Logistic regression estimated the adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for each cohort. RESULTS: The incidence of visualized endometriosis was 40% in the operative cohort (11.8% stage 3-4 by revised criteria from the American Society for Reproductive Medicine), and 11% stage 3-4 in the population cohort by magnetic resonance imaging. An infertility history increased the odds of an endometriosis diagnosis in both the operative (AOR, 2.43; 95% CI, 1.57-3.76) and population (AOR, 7.91; 95% CI, 1.69-37.2) cohorts. In the operative cohort only, dysmenorrhea (AOR, 2.46; 95% CI, 1.28-4.72) and pelvic pain (AOR, 3.67; 95% CI, 2.44-5.50) increased the odds of diagnosis, while gravidity (AOR, 0.49; 95% CI, 0.32-0.75), parity (AOR, 0.42; 95% CI, 0.28-0.64), and body mass index (AOR, 0.95; 95% CI, 0.93-0.98) decreased the odds of diagnosis. In all sensitivity analyses for different diagnostic subgroups, infertility history remained a strong risk factor. CONCLUSION: An infertility history was a consistent risk factor for endometriosis in both the operative and population cohorts of the ENDO Study. Additionally, identified risk factors for endometriosis vary based upon cohort selection and diagnostic accuracy. Finally, endometriosis in the population may be more common than recognized.

RESUMO

Bisphenol A (BPA) and diethylstilbestrol (DES) are endocrine-disrupting chemicals that interact with the human pregnane X receptor (PXR). CYP3A4 enzyme is essential in the hydroxylation of steroid hormones and is regulated by PXR. In the present study, human and rat hepatoma cell lines were exposed to BPA and DES. Both BPA and DES (10-50µM) caused a significant activation of the CYP3A4 promoter via the PXR in the DPX2 human hepatoma cell line. No activation of rat PXR was seen. BPA and DES treated DPX2 cells demonstrated increased expression of CYP3A4 mRNA, and increased enzyme activity. In summary, BPA, in concentrations relevant to current safety levels of human exposure, activates the human PXR and demonstrates an increase in CYP3A4 mRNA expression and enzyme activity. BPA actions in this model system occur to a greater extent than DES. This study raises concerns regarding our current toxicity testing paradigms and species utilization.

RESUMO

The objective of this study was to explore age-related differences in the reproductive and metabolic manifestations of polycystic ovarian syndrome (PCOS). Using a prospective cross-sectional design, we compared metabolic and reproductive findings in women attending a multidisciplinary clinic for PCOS, stratified across the following age groups: 18-25 (n = 71), 26-35 (n = 129), and 36-45 (n = 29). The study included primarily overweight and obese women, with a mean BMI of 31.1 in the entire study group. Older women had a decreased prevalence of biochemical hyperandrogenemia (p-trend: 0.0005). Of women meeting diagnostic criteria for PCOS, older women (n = 15) had larger median waist circumference and higher median diastolic blood pressure, total cholesterol, LDL cholesterol and fasting glucose compared to younger women (p-trend: 0.03, 0.01, 0.01, 0.01 and 0.06, respectively). The odds of metabolic syndrome for women ages 36-45 are increased four-fold relative to the younger groups (OR: 4.01; 95% CI: 1.04-15.4; p = 0.04). We conclude that there are significant age-related differences in both the clinical presentation and metabolic manifestations of PCOS.

RESUMO

OBJECTIVE: To identify markers of ovarian age that best match the pattern of oocyte loss seen in histology specimens. DESIGN: Cross-sectional study. SETTING: University. PATIENT(S): Caucasian women (n = 252) aged 25-45 years. INTERVENTION(S): none. MAIN OUTCOME MEASURE(S): The relationship between antral follicle count (AFC), antimüllerian hormone (AMH), inhibin B, FSH, and E(2) with age was estimated using the power model, which previously has been shown to most accurately describe oocyte loss in histologic specimens. The power model was fit to each marker and used to compare the rates of change at ages 30 and 40 with the histologic pattern. Among those markers following the pattern, R(2) was used to compare the degree of relationship with age. RESULT(S): Both AMH levels and AFC exhibited significant progressive declines with age. The average rates of loss per year for AFC and AMH were, respectively, -0.57 and -1.09 at age 30, and -1.33 and -3.06 at age 40. FSH, inhibin B, and E(2) did not exhibit progressive rates of change. The R(2) for AFC was 27.3% and for AMH was 22.7%. CONCLUSION(S): Only AFC and AMH follow the pattern of oocyte loss observed histologically. Although AMH may be more cost-effective, AFC is a slightly more accurate noninvasive measure for ovarian aging.

RESUMO

OBJECTIVE: To determine whether infertile women have lower antral follicle counts (AFC) than age-matched normal women. DESIGN: Case-control. SETTING: Academic center. PATIENT(S): A total of 881 infertile women and 771 women from the community. INTERVENTION(S): Antral follicle count and basal hormone measurements. MAIN OUTCOME MEASURE(S): Median AFCs and FSH levels were compared between the two groups within 5-year age strata by using the median test. A subanalysis was performed by identifying women in the control group with a history of attempting conception without success (subfertile group) and with a spontaneous conception in fewer than 12 months resulting in a live birth (fertile group). Age-specific AFC percentiles were calculated and compared within strata determined by age at the time of attempted conception. RESULT(S): AFCs were significantly lower in infertile women than in control women across age groups up to 40 years of age. Average FSH levels were significantly higher in the younger-age infertile group versus the community. AFC percentiles differ significantly between fertile and subfertile women within the community up to 40 years of age. CONCLUSION(S): Decreased AFC in infertile women suggests that factors affecting the size of the remaining follicle pool in younger women also affect oocyte quality and the likelihood of conception.

RESUMO

OBJECTIVE: The purpose of this study was to describe the prevalence and predictors of physical activity in women with polycystic ovary syndrome (PCOS) and to explore the potential health benefits that are associated with physical activity in this population. STUDY DESIGN: This was a cross-sectional assessment of 150 women with PCOS. Active women (those who met Department of Health and Human Services [DHHS] guidelines for exercise) were compared with inactive women with regards to demographic and psychosocial variables and health characteristics. RESULTS: Fifty-nine percent (88/150 women) met the DHHS guidelines for physical activity. Active women were more likely than inactive women to be nulliparous (64.1% vs 40.0%; P = .04) and white (71.6% vs 42.6%; P = .0004). Inactive women were more likely to have mild depression (adjusted odds ratio, 2.2; 95% confidence interval, 1.01-4.79; P = .048). CONCLUSION: Women with PCOS who met the DHHS guidelines for physical activity were more likely to enjoy a variety of health benefits. Our findings identify several groups that are at risk for inadequate physical activity.

RESUMO

INTRODUCTION: The age-specific prevalence of polycystic ovaries (PCO), as defined by the Rotterdam criteria, among normal ovulatory women, has not yet been reported. It is also uncertain whether these women differ from their peers in the hormonal or metabolic profile. METHODS: A total of 262 ovulatory Caucasian women aged 25-45 yr, enrolled in a community-based ovarian aging study (OVA), underwent transvaginal ultrasound assessment of ovarian volume and antral follicle count (AFC) in the early follicular phase and were categorized as to whether they met the Rotterdam definition of PCO by AFC (≥12 in one ovary) and/or by volume (>10 cm(3) for one ovary). The effect of age on prevalence of PCO was assessed. Serum hormones and metabolic measures were compared between women meeting each element of the Rotterdam criterion and those without PCO using age-adjusted linear regressions. RESULTS: The prevalence of PCO by AFC was 32% and decreased with age. Those with PCO by AFC had lower FSH; higher anti-Müllerian hormone, estrone, dehydroepiandrostenedione sulfate, and free androgen index; and slightly higher total testosterone than those without PCO. However, slightly higher body mass index and waist circumference were the only metabolic differences. Women with PCO by volume had higher anti-Müllerian hormone and free androgen index but did not differ in any other hormonal or metabolic parameter. DISCUSSION: PCO is a common, age-dependent finding among ovulatory women. These women lack the metabolic abnormalities seen in PCO syndrome. Isolated PCO in an ovulatory woman is not an indication for metabolic evaluation.
