Sexual function in infertile women with polycystic ovary syndrome and unexplained infertility.

BACKGROUND: While female sexual dysfunction is a frequent occurrence, characteristics in infertile women are not well delineated. Furthermore, the impact of infertility etiology on the characteristics in women with differing androgen levels observed in women with polycystic ovary syndrome and unexplained infertility has not been assessed. OBJECTIVE: The objective of the study was to determine the characteristics of sexual dysfunction in women with polycystic ovary syndrome and unexplained infertility. STUDY DESIGN: A secondary data analysis was performed on 2 of Eunice Kennedy Shriver National Institute of Child Health and Human Development Cooperative Reproductive Medicine Networks clinical trials: Pregnancy in Polycystic Ovary Syndrome Study II and Assessment of Multiple Intrauterine Gestations From Ovarian Stimulation. Both protocols assessed female sexual function using the Female Sexual Function Inventory and the Female Sexual Distress Scale. RESULTS: Women with polycystic ovary syndrome had higher weight and body mass index than women with unexplained infertility (each P < .001), greater phenotypic (Ferriman-Gallwey hirsutism score, sebum score, and acne score; each P < .001), and hormonal (testosterone, free testosterone, and dehydroepiandrosterone; each P < .001) evidence of androgen excess. Sexual function scores, as assessed by the Female Sexual Function Inventory, were nearly identical. The Female Sexual Distress Scale total score was higher in women with polycystic ovary syndrome. The mean Female Sexual Function Inventory total score increased slightly as the free androgen index increased, mainly as a result of the desire subscore. This association was more pronounced in the women with unexplained infertility. CONCLUSION: Reproductive-age women with infertility associated with polycystic ovary syndrome and unexplained infertility, despite phenotypic and biochemical differences in androgenic manifestations, do not manifest clinically significant differences in sexual function.

Benefit of Delayed Fertility Therapy With Preconception Weight Loss Over Immediate Therapy in Obese Women With PCOS.

CONTEXT: In overweight/obese women with polycystic ovary syndrome (PCOS), the relative benefit of delaying infertility treatment to lose weight vs seeking immediate treatment is unknown. OBJECTIVE: We compared the results of two, multicenter, concurrent clinical trials treating infertility in women with PCOS. DESIGN, SETTING, AND PARTICIPANTS: This was a secondary analysis of two randomized trials conducted at academic health centers studying women 18-40 years of age who were overweight/obese and infertile with PCOS. INTERVENTION: We compared immediate treatment with clomiphene from the Pregnancy in Polycystic Ovary Syndrome II (PPCOS II) trial (N = 187) to delayed treatment with clomiphene after preconception treatment with continuous oral contraceptives, lifestyle modification (Lifestyle: including caloric restriction, antiobesity medication, behavioral modification, and exercise) or the combination of both (combined) from the Treatment of Hyperandrogenism Versus Insulin Resistance in Infertile Polycystic Ovary Syndrome (OWL PCOS) trial (N = 142). MAIN OUTCOME MEASURES: Live birth, pregnancy loss, and ovulation were measured. RESULTS: In PPCOS II, after four cycles of clomiphene, the cumulative per-cycle ovulation rate was 44.7% (277/619) and the cumulative live birth rate was 10.2% (19/187), nearly identical to that after oral contraceptive pretreatment in the OWL PCOS trial (ovulation 45% [67/149] and live birth: 8.5% [4/47]). In comparison, deferred clomiphene treatment preceded by lifestyle and combined treatment in OWL PCOS offered a significantly better cumulative ovulation rate compared to immediate treatment with clomiphene. (Lifestyle: 62.0% [80/129]; risk ratio compared to PPCOS II = 1.4; 95% confidence interval [CI], 1.1-1.7; P = .003; combined: 64.3% [83/129]; risk ratio compared to PPCOS II = 1.4; 95% CI, 1.2-1.8; P < .001 and a significantly better live birth rate lifestyle: 25.0% [12/48]; risk ratio compared to PPCOS II = 2.5; 95% CI, 1.3-4.7; P = .01 and combined: 25.5% [12/47]; risk ratio compared to PPCOS II = 2.5; 95% CI, 1.3-4.8; P = .01). CONCLUSIONS: These data show the benefit of improved ovulation and live birth with delayed infertility treatment with clomiphene citrate when preceded by lifestyle modification with weight loss compared with immediate treatment. Pretreatment with oral contraceptives likely has little effect on the ovulation and live birth rate compared with immediate treatment.

Identification and replication of prediction models for ovulation, pregnancy and live birth in infertile women with polycystic ovary syndrome.

STUDY QUESTION: Can we build and validate predictive models for ovulation and pregnancy outcomes in infertile women with polycystic ovary syndrome (PCOS)? SUMMARY ANSWER: We were able to develop and validate a predictive model for pregnancy outcomes in women with PCOS using simple clinical and biochemical criteria particularly duration of attempting conception, which was the most consistent predictor among all considered factors for pregnancy outcomes. WHAT IS KNOWN ALREADY: Predictive models for ovulation and pregnancy outcomes in infertile women with polycystic ovary syndrome have been reported, but such models require validation. STUDY DESIGN, SIZE, AND DURATION: This is a secondary analysis of the data from the Pregnancy in Polycystic Ovary Syndrome I and II (PPCOS-I and -II) trials. Both trials were double-blind, randomized clinical trials that included 626 and 750 infertile women with PCOS, respectively. PPCOS-I participants were randomized to either clomiphene citrate (CC), metformin, or their combination, and PPCOS-II participants to either letrozole or CC for up to five treatment cycles. PARTICIPANTS/MATERIALS, SETTING, AND METHODS: Linear logistic regression models were fitted using treatment, BMI, and other published variables as predictors of ovulation, conception, clinical pregnancy, and live birth as the outcome one at a time. We first evaluated previously reported significant predictors, and then constructed new prediction models. Receiver operating characteristic (ROC) curves were constructed and the area under the curves (AUCs) was calculated to compare performance using different models and data. Chi-square tests were used to examine the goodness-of-fit and prediction power of logistic regression model. MAIN RESULTS AND THE ROLE OF CHANCE: Predictive factors were similar between PPCOS-I and II, but the two participant samples differed statistically significantly but the differences were clinically minor on key baseline characteristics and hormone levels. Women in PPCOS-II had an overall more severe PCOS phenotype than women in PPCOS-I. The clinically minor but statistically significant differences may be due to the large sample sizes. Younger age, lower baseline free androgen index and insulin, shorter duration of attempting conception, and higher baseline sex hormone-binding globulin significantly predicted at least one pregnancy outcome. The ROC curves (with AUCs of 0.66-0.76) and calibration plots and chi-square tests indicated stable predictive power of the identified variables (P-values ≥0.07 for all goodness-of-fit and validation tests). LIMITATIONS, REASONS FOR CAUTION: This is a secondary analysis. Although our primary objective was to confirm previously reported results and identify new predictors of ovulation and pregnancy outcomes among PPCOS-II participants, our approach is exploratory and warrants further replication. WIDER IMPLICATIONS OF THE FINDINGS: We have largely confirmed the predictors that were identified in the PPCOS-I trial. However, we have also revealed new predictors, particularly the role of smoking. While a history of ever smoking was not a significant predictor for live birth, a closer look at current, quit, and never smoking revealed that current smoking was a significant risk factor.

Ovulation induction.

Before initiating ovulation induction, it is important to evaluate the underlying cause of a patient's anovulation and to make lifestyle modifications or treat underlying medical conditions, as appropriate. Here, ovulation induction agents are discussed with attention to their pharmacology, indications for use, therapy regimens, and efficacy. Adjuvant therapies and appropriate monitoring are also reviewed.

Potential causes of subfertility in patients with intramural fibroids.

BACKGROUND: Intramural leiomyomas have been long debated as a potential cause of infertility and pregnancy loss. FINDINGS: Previous research has linked intramural fibroids to defective implantation, as well as to abnormal peristaltic events of the uterine smooth muscle. Previous reports describe the effects of intramural fibroids on normal human fertility and early pregnancy loss, specifically in regards to implantation failure. CONCLUSION: A thorough understanding of prior research may direct new research focus, leading to better understanding of leiomyoma-associated infertility.

Letrozole versus clomiphene for infertility in the polycystic ovary syndrome.

BACKGROUND: Clomiphene is the current first-line infertility treatment in women with the polycystic ovary syndrome, but aromatase inhibitors, including letrozole, might result in better pregnancy outcomes. METHODS: In this double-blind, multicenter trial, we randomly assigned 750 women, in a 1:1 ratio, to receive letrozole or clomiphene for up to five treatment cycles, with visits to determine ovulation and pregnancy, followed by tracking of pregnancies. The polycystic ovary syndrome was defined according to modified Rotterdam criteria (anovulation with either hyperandrogenism or polycystic ovaries). Participants were 18 to 40 years of age, had at least one patent fallopian tube and a normal uterine cavity, and had a male partner with a sperm concentration of at least 14 million per milliliter; the women and their partners agreed to have regular intercourse with the intent of conception during the study. The primary outcome was live birth during the treatment period. RESULTS: Women who received letrozole had more cumulative live births than those who received clomiphene (103 of 374 [27.5%] vs. 72 of 376 [19.1%], P=0.007; rate ratio for live birth, 1.44; 95% confidence interval, 1.10 to 1.87) without significant differences in overall congenital anomalies, though there were four major congenital anomalies in the letrozole group versus one in the clomiphene group (P=0.65). The cumulative ovulation rate was higher with letrozole than with clomiphene (834 of 1352 treatment cycles [61.7%] vs. 688 of 1425 treatment cycles [48.3%], P<0.001). There were no significant between-group differences in pregnancy loss (49 of 154 pregnancies in the letrozole group [31.8%] and 30 of 103 pregnancies in the clomiphene group [29.1%]) or twin pregnancy (3.4% and 7.4%, respectively). Clomiphene was associated with a higher incidence of hot flushes, and letrozole was associated with higher incidences of fatigue and dizziness. Rates of other adverse events were similar in the two treatment groups. CONCLUSIONS: As compared with clomiphene, letrozole was associated with higher live-birth and ovulation rates among infertile women with the polycystic ovary syndrome.

State-mandated insurance coverage is associated with the approach to hydrosalpinges before IVF.

The aim of this study was to determine whether practice in states with infertility insurance mandates is associated with physician-reported practice patterns regarding hydrosalpinx management in assisted reproduction clinics. A cross-sectional, internet-based survey of 442 members of Society for Reproductive Endocrinology and Infertility or Society of Reproductive Surgeons was performed. Physicians practising in states without infertility insurance mandates were more likely to report performing diagnostic surgery after an inconclusive hysterosalpingogram than physicians practising in states with mandates (RR 1.2, 95% CI 1.1-1.3, P < 0.01). Additionally, respondents in states without mandates were more likely to report that, due to lack of infertility insurance coverage, they did not perform salpingectomy (SPX) or proximal tubal occlusion (PTO) before assisted reproduction treatment (RR 1.4, 95% CI 1.1-1.8, P = 0.01). Finally, respondents in states without mandates were less likely to report that the presence of assisted reproduction treatment coverage determined the urgency with which they pursued SPX or PTO before treatment (RR 0.7, 95% CI 0.5-1.0, NS). These results persisted after controlling for physician years in practice, age and clinic volume. In conclusion, self-reported physician practice interventions for hydrosalpinges before assisted reproduction treatment may be associated with state-mandated infertility insurance. Fallopian tube dysfunction is a known cause of infertility and severe dysfunction is manifested by dilation and occlusion, known as hydrosalpinx. Outcomes with assisted reproductive techniques (ART) are lower when hydrosalpinges are present and while there are several theories for this, reproductive specialist recommend "neutralizing" the tube either by occlusion or removal in order to enhance pregnancy rates. In the United States, coverage for infertility services is not uniform with only 15 states having some legislation requiring infertility benefits. Some states where ART is covered liberally, physicians might have different practice patterns related to the neutralization of hydrosalpinges compared to those who are in non -mandated states. We utilized a survey of over 400 providers in the United States to examine their practice patterns as it relates to hydrosalpinges based on which state they practice in and whether or not that state has mandated coverage of not.

The Pregnancy in Polycystic Ovary Syndrome II study: baseline characteristics and effects of obesity from a multicenter randomized clinical trial.

OBJECTIVE: To summarize baseline characteristics from a large multicenter infertility clinical trial. DESIGN: Cross-sectional baseline data from a double-blind randomized trial of two treatment regimens (letrozole vs. clomiphene). SETTING: Academic Health Centers throughout the United States. PATIENT(S): Seven hundred fifty women with polycystic ovary syndrome (PCOS) and their male partners took part in the study. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Historic, biometric, biochemical, and questionnaire parameters. RESULT(S): Females averaged 30 years and were obese (body mass index [BMI] 35) with ∼20% from a racial/ethnic minority. Most (87%) were hirsute and nulligravid (63%). Most of the women had an elevated antral follicle count and enlarged ovarian volume on ultrasound. Women had elevated mean circulating androgens, LH-to-FSH ratio (∼2), and antimüllerian hormone levels (8.0 ng/mL). In addition, women had evidence for metabolic dysfunction with elevated mean fasting insulin and dyslipidemia. Increasing obesity was associated with decreased LH-to-FSH levels, antimüllerian hormone levels, and antral follicle counts but increasing cardiovascular risk factors, including prevalence of the metabolic syndrome. Men were obese (BMI 30) and had normal mean semen parameters. CONCLUSION(S): The treatment groups were well matched at baseline. Obesity exacerbates select female reproductive and most metabolic parameters. We have also established a database and sample repository that will eventually be accessible to investigators. CLINICAL TRIAL REGISTRATION NUMBER: NCT00719186.

Favourable metabolic effects of a eucaloric lower-carbohydrate diet in women with PCOS.

OBJECTIVE: Diet-induced reduction in circulating insulin may be an attractive nonpharmacological treatment for women with polycystic ovary syndrome (PCOS) among whom elevated insulin may exacerbate symptoms by stimulating testosterone synthesis. This study was designed to determine whether a modest reduction in dietary carbohydrate (CHO) content affects ß-cell responsiveness, serum testosterone concentration and insulin sensitivity in women with PCOS. DESIGN: In a crossover design, two diets ('Standard,' STD, 55:18:27% energy from carbohydrate/protein/fat; lower-carbohydrate, 41:19:40) were provided for 8 weeks in random order with a 4-week washout between. PATIENTS: Thirty women with PCOS. MEASUREMENTS: ß-cell responsiveness assessed as the C-peptide response to glucose during a liquid meal test; insulin sensitivity from insulin and glucose values throughout the test; insulin resistance (HOMA-IR); and total testosterone by immunoassay. RESULTS: Paired t-test indicated that the lower-CHO diet induced significant decreases in basal ß-cell response (PhiB), fasting insulin, fasting glucose, HOMA-IR, total testosterone and all cholesterol measures, and significant increases in insulin sensitivity and dynamic ('first-phase') ß-cell response. The STD diet induced a decrease in HDL-C and an increase in the total cholesterol-to-HDL-C ratio. Across all data combined, the change in testosterone was positively associated with the changes in fasting insulin, PhiB and insulin AUC (P < 0·05). CONCLUSIONS: In women with PCOS, modest reduction in dietary CHO in the context of a weight-maintaining diet has numerous beneficial effects on the metabolic profile that may lead to a decrease in circulating testosterone.

Physiology of the female reproductive axis.

The female reproductive system contains two principal components: the uterus, which supports the developing fetus, and the ovaries, which produce the female gametes. This manuscript will review how the hypothalamus, pituitary, ovary and uterus are integrated into the female reproductive system. The endocrinology of pregnancy, as well as a cursory overview of reproductive pathology, will be presented in each section. In addition, the most common endocrinopathy in women, polycystic ovarian syndrome, as well as the early loss of reproductive function, premature ovarian failure, will receive special mention.

Polycystic ovarian syndrome management options.

Polycystic ovarian syndrome (PCOS) is a disorder of androgen excess and ovarian dysfunction. Hirsutism and elevated free testosterone levels are the most consistent signs of the androgen excess. Irregular, infrequent, or absent menses and infertility are symptoms of ovulatory dysfunction. Obesity is also a feature of this syndrome and contributes to associated metabolic abnormalities. Lifestyle modification should be the first treatment and is effective in reducing the signs and symptoms. The ovulatory infertility associated with PCOS can be overcome in most cases with oral (clomiphene citrate or letrozole) or injectable (gonadotropins) agents. Surgical intervention is reserved for cases resistant to medical management.

Evaluation and treatment of anovulatory and unexplained infertility.

Anovulatory disorders are a primary cause of female infertility. Polycystic ovarian syndrome is the major cause of anovulation and is generally associated with obesity. Lifestyle changes to encourage weight loss are the initial therapy for overweight and obese patients, followed by clomiphene citrate for ovulation induction. For those patients who fail to ovulate on clomiphene citrate, alternatives, such as letrozole; gonadotropins; and complimentary agents to enhance clomiphene citrate, such as metformin and glucocorticoids, are reviewed. Women with unexplained infertility (no identifiable cause of infertility on a routine evaluation) may benefit from ovulation induction with clomiphene citrate, letrozole, or gonadotropins.

Fertility preservation in women of reproductive age with cancer.

Advances in cancer care have improved survival, driving the need to mitigate the side effects of cancer therapy to improve the quality of life of cancer survivors. Use of fertility preservation has grown given the potential gonadotoxicity of chemotherapy and radiation, the increasing rate of treatment success, and the strong desire for childbearing in cancer survivors. Current options include embryo and oocyte cryopreservation, ovarian tissue cryopreservation, gonadal suppression, and ovarian transposition. Consultation with a reproductive endocrinology and infertility specialist trained in fertility preservation provides cancer patients an individualized risk assessment for future gonadal failure and discussion of potential fertility preservation options.

Atypical presentation and management dilemma of mixed gonadal dysgenesis.

OBJECTIVE: To describe a case of 45,X/46,XY mixed gonadal dysgenesis complicated by malignancy with possible metastasis. DESIGN: Case report. SETTING: University hospital. PATIENT(S): A 15-year-old female with primary amenorrhea, short stature, and a vaginal septum. INTERVENTION(S): Resection of transverse vaginal septum and laparoscopic bilateral gonadectomy. RESULT(S): The patient had dysgerminoma arising from gonadoblastoma in the left gonad and gonadoblastoma in the right gonad. No normal gonadal tissue could be identified. Postoperative computed tomography scan results were suspicious for lung metastases, but the patient opted for conservative management without chemotherapy. CONCLUSION(S): Mixed gonadal dysgenesis involves inherent malignancy risk and complex psychosocial issues, which necessitate a multidisciplinary approach to diagnosis and treatment.

Self-assessed knowledge of treatment and fertility preservation in young women with breast cancer.

Young women with breast cancer do not identify themselves as knowledgeable about the effect of cancer treatment on fertility or fertility preservation treatments and resources. These women need access to high-quality health information to support their participation in medical decision making about fertility preservation.

Postcesarean delivery adhesions associated with delayed delivery of infant.

OBJECTIVE: The purpose of this study was to estimate the incidence of adhesions after cesarean deliveries and to determine their impact on delivery and infant well-being. STUDY DESIGN: This was a retrospective cohort analysis with chart review. The charts of 542 women who had undergone primary (265 women) or repeat cesarean (277 women) deliveries were reviewed. The incidence, severity, and locations of adhesions; delivery time; cord blood pH, and Apgar scores were noted. RESULTS: After the first cesarean delivery, 100 of 217 women (46%) had pelvic adhesive disease; 48 of 64 women (75%) who underwent a third cesarean delivery and 5 of 6 women (83%) who underwent a fourth cesarean delivery had formed pelvic adhesive disease. Compared with primary cesarean section, delivery of the infant was delayed 5.6 minutes (52%) with 1 previous cesarean birth, 8.5 minutes (79%) after 2 cesarean birth, and 18.1 (169%) during the fourth cesarean birth (P < 0.001 for all comparisons). CONCLUSION: A high percentage of cesarean deliveries result in adhesive disease, which delays repeat cesarean delivery of the fetus. The potential for adhesive disease should be included in counseling regarding primary elective cesarean births.
