Smoking in infertile women with polycystic ovary syndrome: baseline validation of self-report and effects on phenotype.

STUDY QUESTION: Do women with polycystic ovary syndrome (PCOS) seeking fertility treatment report smoking accurately and does participation in infertility treatment alter smoking? SUMMARY ANSWER: Self-report of smoking in infertile women with PCOS is accurate (based on serum cotinine levels) and smoking is unlikely to change over time with infertility treatment. WHAT IS KNOWN ALREADY: Women with PCOS have high rates of smoking and it is associated with worse insulin resistance and metabolic dysfunction. STUDY DESIGN, SIZE, DURATION: Secondary study of smoking history from a large randomized controlled trial of infertility treatments in women with PCOS (N = 626) including a nested case-control study (N = 148) of serum cotinine levels within this cohort to validate self-report of smoking. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women with PCOS, age 18-40, seeking fertility who participated in a multi-center clinical trial testing first-line ovulation induction agents conducted at academic health centers in the USA. MAIN RESULTS AND THE ROLE OF CHANCE: Overall, self-report of smoking in the nested case-control study agreed well with smoking status as determined by measure of serum cotinine levels, at 90% or better for each of the groups at baseline (98% of never smokers had cotinine levels <15 ng/ml compared with 90% of past smokers and 6% of current smokers). There were minor changes in smoking status as determined by serum cotinine levels over time, with the greatest change found in the smoking groups (past or current smokers). In the larger cohort, hirsutism scores at baseline were lower in the never smokers compared with past smokers. Total testosterone levels at baseline were also lower in the never smokers compared with current smokers. At end of study follow-up insulin levels and homeostatic index of insulin resistance increased in the current smokers (P < 0.01 for both) compared with baseline and with non-smokers. The chance for ovulation was not associated with smoking status, but live birth rates were increased (non-significantly) in never or past smokers. LIMITATIONS, REASONS FOR CAUTION: The limitations include the selection bias involved in our nested case-control study, the possibility of misclassifying exposure to second hand smoke as smoking and our failure to capture self-reported changes in smoking status after enrollment in the trial. WIDER IMPLICATIONS OF THE FINDINGS: Because self-report of smoking is accurate, further testing of smoking status is not necessary in women with PCOS. Because smoking status is unlikely to change during infertility treatment, extra attention should be focused on smoking cessation in current or recent smokers who seek or who are receiving infertility treatment.

Clomiphene, metformin, or both for infertility in the polycystic ovary syndrome.

BACKGROUND: The polycystic ovary syndrome is a common cause of infertility. Clomiphene and insulin sensitizers are used alone and in combination to induce ovulation, but it is unknown whether one approach is superior. METHODS: We randomly assigned 626 infertile women with the polycystic ovary syndrome to receive clomiphene citrate plus placebo, extended-release metformin plus placebo, or a combination of metformin and clomiphene for up to 6 months. Medication was discontinued when pregnancy was confirmed, and subjects were followed until delivery. RESULTS: The live-birth rate was 22.5% (47 of 209 subjects) in the clomiphene group, 7.2% (15 of 208) in the metformin group, and 26.8% (56 of 209) in the combination-therapy group (P<0.001 for metformin vs. both clomiphene and combination therapy; P=0.31 for clomiphene vs. combination therapy). Among pregnancies, the rate of multiple pregnancy was 6.0% in the clomiphene group, 0% in the metformin group, and 3.1% in the combination-therapy group. The rates of first-trimester pregnancy loss did not differ significantly among the groups. However, the conception rate among subjects who ovulated was significantly lower in the metformin group (21.7%) than in either the clomiphene group (39.5%, P=0.002) or the combination-therapy group (46.0%, P<0.001). With the exception of pregnancy complications, adverse-event rates were similar in all groups, though gastrointestinal side effects were more frequent, and vasomotor and ovulatory symptoms less frequent, in the metformin group than in the clomiphene group. CONCLUSIONS: Clomiphene is superior to metformin in achieving live birth in infertile women with the polycystic ovary syndrome, although multiple birth is a complication.

Assessing Human Immunodeficiency Virus (HIV) Prevention Through Knowledge and Condom Use Among Female Sex Workers at the Border of Haiti and Dominican Republic.

Geographic border studies are relatively scare, but have the potential to inform bilateral health policies that affect the well-being of female sex workers (FSWs) who work at these borders as well as those individuals who solicit their services, both groups being at high risk for human immunodeficiency virus (HIV). We applied bivariate and multivariate techniques to examine FSWs' HIV knowledge and condom use across three partner types, at the Haiti Dominican Republic border, using data from the Study on Sex Workers (n = 241, 2014). Condom use was significantly lower among FSWs on the Haitian side of the border compared to the Dominican side, yet levels of HIV knowledge were similar; specifically, 81% of respondents on the Dominican side reported using condoms every time they had sex with a client, compared to 38% of peers in Haiti (p < 0.001). After introducing controls, FSWs in Haiti continued to have lower odds of using condoms with clients (p < 0.001), noncommercial partners (p < 0.001), and regular partners (p < 0.05) compared to peers in the Dominican Republic. This unique border study highlights disparities in FSWs' condom use regardless of HIV knowledge. The lack of consistent condom use by FSWs in Haiti has the potential to exacerbate the HIV epidemic at the border and impact both nations' HIV incidence rates.

Extended-release metformin does not reduce the clomiphene citrate dose required to induce ovulation in polycystic ovary syndrome.

CONTEXT: When used for ovulation induction, higher doses of clomiphene may lead to antiestrogenic side effects that reduce fecundity. It has been suggested that metformin in combination with clomiphene can restore ovulation to some clomiphene-resistant anovulators with polycystic ovary syndrome (PCOS). OBJECTIVE: Our objective was to determine if cotreatment with extended-release metformin (metformin XR) can lower the threshold dose of clomiphene needed to induce ovulation in women with PCOS. DESIGN: A secondary analysis of data from the National Institute of Child Health and Human Development Cooperative Multicenter Reproductive Medicine Network prospective, double-blind, placebo-controlled multicenter clinical trial, Pregnancy in Polycystic Ovary Syndrome, was performed. SETTING: Study volunteers at multiple academic medical centers were included. PARTICIPANTS: Women with PCOS and elevated serum testosterone who were randomized to clomiphene alone or with metformin (n = 209 in each group) were included in the study. INTERVENTIONS: Clomiphene citrate, 50 mg daily for 5 d, was increased to 100 and 150 mg in subsequent cycles if ovulation was not achieved; half also received metformin XR, 1000 mg twice daily. Treatment was for up to 30 wk or six cycles, or until first pregnancy. MAIN OUTCOME MEASURES: Ovulation was confirmed by a serum progesterone more than or equal to 5 ng/ml, drawn prospectively every 1-2 wk. RESULTS: The overall prevalence of at least one ovulation after clomiphene was 75 and 83% (P = 0.04) for the clomiphene-only and clomiphene plus metformin groups, respectively. Using available data from 314 ovulators, the frequency distribution of the lowest clomiphene dose (50, 100, or 150 mg daily) resulting in ovulation was indistinguishable between the two treatment groups. CONCLUSION: Metformin XR does not reduce the lowest dose of clomiphene that induces ovulation in women with PCOS.

Ovulatory response to treatment of polycystic ovary syndrome is associated with a polymorphism in the STK11 gene.

CONTEXT: Clomiphene and insulin sensitizers such as metformin are used to induce ovulation in polycystic ovary syndrome (PCOS), but the ovulatory response is variable, and the causes of this variation are poorly understood. OBJECTIVE: Our objective was to identify predictive genetic polymorphisms and other determinants of ovulatory response. DESIGN: This was a substudy of a multicenter randomized clinical trial. SETTING: This study was performed at academic medical centers and their affiliates. PARTICIPANTS: A total of 312 women with PCOS were included in the study. MAIN OUTCOME MEASURES: Historical, biometric, biochemical, and genetic parameters were performed. RESULTS: We found that the C allele of a single nucleotide polymorphism in the STK11 gene (expressed in liver; also known as LKB1) was associated with a significantly decreased chance of ovulation in PCOS women treated with metformin. In an analysis of ovulation per cycle, the adjusted odds ratio (OR) comparing the C/C genotype to the G/G genotype was 0.30 [95% confidence interval (CI) 0.14, 0.66], and the OR for the C/G genotype vs. the G/G genotype was also 0.30 (95% CI 0.14, 0.66). In an analysis of metformin-treated subjects, we found that the percentage of women who ovulated increased with the number of G alleles present: 48% (10 of 21) of C/C women, 67% (32 of 48) of C/G women, and 79% (15 of 19) of G/G women ovulated. We also found that increased frequency of ovulation was associated with lower body mass index (BMI) [adjusted OR of 2.36 (95% CI 1.65, 3.36) and 2.05 (95% CI 1.46, 2.88), respectively, for comparisons of BMI less than 30 vs. BMI equal to or more than 35, BMI 30-34 vs. BMI equal to or more than 35, in the analysis of ovulation per cycle], a lower free androgen index (FAI) [adjusted OR of 1.59 (95% CI 1.17, 2.18) for FAI<10 vs. FAI>or=10], and a shorter duration of attempting conception [adjusted OR of 1.63 (95% CI 1.20, 2.21) for<1.5 vs.>or=1.5 yr]. CONCLUSIONS: We have demonstrated that a polymorphism in STK11, a kinase gene expressed in liver and implicated in metformin action, is associated with ovulatory response to treatment with metformin alone in a prospective randomized trial. The interaction with the effects of changes in modifiable factors (e.g. BMI or FAI) requires further study.

Examining the Use of Magnesium Sulfate to Treat Pregnant Women with Preeclampsia and Eclampsia: Results of a Program Assessment of Emergency Obstetric Care (EmOC) Training in India.

BACKGROUND: The aim of this study is to examine rates of magnesium sulfate utilization by emergency obstetric care trainees to treat preeclampsia-eclampsia in India. Secondarily, structural barriers are identified which limit the use of magnesium sulfate, highlighting limitations of emergency obstetric care training, which is a commonly implemented intervention in resource-poor settings. METHODS: Trainees' curriculum specified magnesium sulfate treatment for eclampsia and severe preeclampsia. Case records were analyzed for preeclampsia-eclampsia diagnosis, magnesium sulfate utilization, delivery route, and maternal and neonatal outcomes from 13,238 reported deliveries between 2006 and 2012 across 75 district hospitals in 12 Indian states. RESULTS: Of 1320 cases of preeclampsia-eclampsia, 322 (24.4%) had eclampsia. Magnesium sulfate was given to 12.9% of preeclamptic and 54.3% of eclamptic women, with lower usage rates in rural communities. Among the 1308 women with preeclampsia-eclampsia, only 24 deaths occurred (1.8%). In contrast, among the 17,179 women without preeclampsia-eclampsia, there were 95 reported deaths (0.6%). Both maternal mortality ratios were found to be much higher than the Millennium Development Goal target of 0.15%. Magnesium sulfate administration was associated with a higher death rate in preeclamptic but not eclamptic women, representing possible confounding by severity. CONCLUSION: To optimize resources spent on emergency obstetric care training, the consistent availability of magnesium sulfate should be improved in India. Increasing drug availability, implementing clinical guidelines around its administration, and training health-care providers on the identification and treatment of preeclampsia-eclampsia could lead to notable improvements in maternal and infant mortality.

Vitamin D Status Relates to Reproductive Outcome in Women With Polycystic Ovary Syndrome: Secondary Analysis of a Multicenter Randomized Controlled Trial.

CONTEXT: Experimental evidence supports a relevance of vitamin D (VitD) for reproduction; however, data in humans are sparse and inconsistent. OBJECTIVE: To assess the relationship of VitD status with ovulation induction (OI) outcomes in women with polycystic ovary syndrome (PCOS). DESIGN: A retrospective cohort. SETTING: Secondary analysis of randomized controlled trial data. PARTICIPANTS: Participants in the Pregnancy in PCOS I (PPCOS I) randomized controlled trial (n = 540) met the National Institutes of Health diagnostic criteria for PCOS. INTERVENTIONS: Serum 25OHD levels were measured in stored sera. MAIN OUTCOME MEASURES: Primary, live birth (LB); secondary, ovulation and pregnancy loss after OI. RESULTS: Likelihood for LB was reduced by 44% for women if the 25OHD level was < 30 ng/mL (<75 nmol/L; odds ratio [OR], 0.58 [0.35-0.92]). Progressive improvement in the odds for LB was noted at thresholds of ≥38 ng/mL (≥95 nmol/L; OR, 1.42 [1.08-1.8]), ≥40 ng/mL (≥100 nmol/L; OR, 1.51 [1.05-2.17]), and ≥45 ng/mL (≥112.5 nmol/L; OR, 4.46 [1.27-15.72]). On adjusted analyses, VitD status was an independent predictor of LB and ovulation after OI. CONCLUSIONS: In women with PCOS, serum 25OHD was an independent predictor of measures of reproductive success after OI. Our data identify reproductive thresholds for serum 25OHD that are higher than recommended for the nonpregnant population.

Gestational hypothyroidism: development of mild hypothyroidism in early pregnancy in previously euthyroid women.

OBJECTIVE: To determine the proportion of euthyroid women attending a fertility practice who develop hypothyroidism in very early pregnancy (gestational hypothyroidism [GHT]), and to examine the association of GHT with exogenous gonadotropin treatment. DESIGN: Retrospective cohort study. SETTING: A private reproductive medicine practice. PATIENT(S): All healthy women (N = 94) with infertility or recurrent pregnancy loss, TSH level <2.5 mIU/L, negative thyroid peroxidase antibodies at initial evaluation, and not taking thyroid medication, who conceived during an 18-month period. INTERVENTION(S): Usual fertility care; 30 women who had received exogenous gonadotropins. MAIN OUTCOME MEASURE(S): Serum TSH level at the time of pregnancy detection. RESULT(S): Gestational hypothyroidism (TSH ≥ 2.5 mIU/L) developed in 23 of 94 women (24%). The mean increase in serum TSH level from initial evaluation to early pregnancy was 0.45 ± 0.08 [SE] mIU/L. There was a trend toward the association of GHT with use of exogenous gonadotropins. Gestational hypothyroidism was positively associated with initial prepregnancy TSH level. CONCLUSION(S): Euthyroid women may develop mild hypothyroidism in early pregnancy, especially after exogenous gonadotropin treatment. Appropriate vigilance will allow for timely levothyroxine treatment.

Endometrial shedding effect on conception and live birth in women with polycystic ovary syndrome.

OBJECTIVE: To estimate whether progestin-induced endometrial shedding, before ovulation induction with clomiphene citrate, metformin, or a combination of both, affects ovulation, conception, and live birth rates in women with polycystic ovary syndrome (PCOS). METHODS: A secondary analysis of the data from 626 women with PCOS from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Cooperative Reproductive Medicine Network trial was performed. Women had been randomized to up to six cycles of clomiphene citrate alone, metformin alone, or clomiphene citrate plus metformin. Women were assessed for occurrence of ovulation, conception, and live birth in relation to prior bleeding episodes (after either ovulation or exogenous progestin-induced withdrawal bleed). RESULTS: Although ovulation rates were higher in cycles preceded by spontaneous endometrial shedding than after anovulatory cycles (with or without prior progestin withdrawal), both conception and live birth rates were significantly higher after anovulatory cycles without progestin-induced withdrawal bleeding (live births per cycle: spontaneous menses 2.2%; anovulatory with progestin withdrawal 1.6%; anovulatory without progestin withdrawal 5.3%; P<.001). The difference was more marked when rate was calculated per ovulation (live births per ovulation: spontaneous menses 3.0%; anovulatory with progestin withdrawal 5.4%; anovulatory without progestin withdrawal 19.7%; P<.001). CONCLUSION: Conception and live birth rates are lower in women with PCOS after a spontaneous menses or progestin-induced withdrawal bleeding as compared with anovulatory cycles without progestin withdrawal. The common clinical practice of inducing endometrial shedding with progestin before ovarian stimulation may have an adverse effect on rates of conception and live birth in anovulatory women with PCOS. LEVEL OF EVIDENCE: II.

Altering hirsutism through ovulation induction in women with polycystic ovary syndrome.

OBJECTIVE: Many women with polycystic ovary syndrome (PCOS) experience infertility and hirsutism and often seek treatment for both concurrently. We investigated whether women who ovulate in response to treatment with clomiphene citrate, metformin, or both would have greater improvement in hirsutism compared with those who did not ovulate. METHODS: This is a secondary analysis evaluating the change in Ferriman-Gallwey score for the hirsute women (n=505 [80.7%]) from the Pregnancy in Polycystic Ovary Syndrome I study. This was a prospective, randomized, doubled-blind trial of 626 women with PCOS and infertility recruited from 12 university sites. They were treated with clomiphene citrate, metformin, or both (combination) for up to six cycles, and hirsutism evaluators were blinded to group assignment. RESULTS: There was a significant decrease in the Ferriman-Gallwey score between baseline and completion of the study in each of the three individual groups (clomiphene citrate, P=.024; metformin, P=.005; combination, P<.001). There was no significant difference in the degree to which the hirsutism score changed when comparing the three groups (P=.44). The change in hirsutism was not associated with the duration of treatment or with the presence or absence of ovulation. CONCLUSION: In infertile hirsute women with PCOS, treatment with clomiphene citrate, metformin, or both for up to six cycles does not alter hirsutism.

Metformin and/or clomiphene do not adversely affect liver or renal function in women with polycystic ovary syndrome.

CONTEXT: Nonalcoholic fatty liver disease is common to insulin-resistant states such as polycystic ovary syndrome (PCOS). Metformin (MET) is often used to treat PCOS but information is limited as to its effects on liver function. OBJECTIVE: We sought to determine the effects of MET on serum hepatic parameters in PCOS patients. DESIGN: This was a secondary analysis of a randomized, doubled-blind trial from 2002-2004. SETTING: This multi-center clinical trial was conducted in academic centers. PATIENTS: Six hundred twenty-six infertile women with PCOS with serum liver function parameters less than twice the upper limit of normal were included. INTERVENTIONS: Clomiphene citrate (n = 209), MET (n = 208), or combined (n = 209) were given for up to 6 months. MAIN OUTCOME MEASURE: The percent change from baseline in renal and liver function between- and within-treatment arms was assessed. RESULTS: Renal function improved in all treatment arms with significant decreases in serum blood urea nitrogen levels (range, -14.7 to -21.3%) as well as creatinine (-4.2 to -6.9%). There were similar decreases in liver transaminase levels in the clomiphene citrate and combined arms (-10% in bilirubin, -9 to -11% in transaminases) without significant changes in the MET arm. When categorizing baseline bilirubin, aspartate aminotransferase, and alanine aminotransferase into tertiles, there were significant within-treatment arm differences between the tertiles with the highest tertile having the largest decrease from baseline regardless of treatment arm. CONCLUSION: Women with PCOS can safely use metformin and clomiphene even in the setting of mildly abnormal liver function parameters, and both result in improved renal function.

Intercourse compliance, ovulation, and treatment success in the National Institute of Child Health and Human Development-Reproductive Medicine Network's Pregnancy in Polycystic Ovary Syndrome (PPCOS) Trial.

OBJECTIVE: To investigate the relationship among intercourse compliance, ovulation, and the occurrence of pregnancy in the Reproductive Medicine Network's Pregnancy in Polycystic Ovary Syndrome (RMNPPCOS) Trial. DESIGN: Post hoc data analysis of subjects in the Reproductive Medicine Network PPCOS Trial. SETTING: Academic medical centers. INTERVENTION(S): None. PATIENT(S): Six hundred twenty-six infertile women with polycystic ovary syndrome with a mean age of 28.1+/-4 years and mean body mass index of 35.2+/-8.7 kg/m2. MAIN OUTCOME MEASURE(S): Intercourse compliance, ovulation, and pregnancy. RESULT(S): Data on 2925 cycles were included in the analysis, of which 1340 were ovulatory cycles and 1585 were nonovulatory cycles. The rates of intercourse compliance in the PPCOS trial were similar across all treatment groups at all cycles except cycle 4. Among cycles with known ovulation status, 81.2% of patients were compliant with intercourse instructions. Patients were more intercourse compliant in those cycles during which ovulation occurred (83.2% vs. 79.4%). With regard to ovulatory cycles, there was no difference in the occurrence of pregnancy when comparing intercourse compliant versus intercourse noncompliant cycles. CONCLUSION(S): Intercourse compliance was not associated with the occurrence of pregnancy in ovulatory cycles in the PPCOS Trial. The occurrence of ovulation still remains a critical predictor for the occurrence of pregnancy.

Body mass index and intercourse compliance.

OBJECTIVE: To investigate the relationship between body mass index and intercourse compliance in the Reproductive Medicine Network's Pregnancy in Polycystic Ovary Syndrome (RMN PPCOS) Trial. DESIGN: Post hoc data analysis of subjects in the RMN PPCOS Trial. SETTING: Academic medical centers. INTERVENTION(S): None. PATIENT(S): Six hundred twenty-six infertile women with polycystic ovary syndrome (PCOS) with a mean age of 28.1+/-4 years and mean body mass index (BMI) of 35.2+/-8.7 kg/m2. MAIN OUTCOME MEASURE(S): Intercourse compliance and BMI. RESULT(S): Overall, body mass index was not associated with increased intercourse compliance. However, although patients with BMI>or=35 were less likely to ovulate than patients with BMI<35, they tend to be more compliant with intercourse frequency in ovulatory cycles than patients with BMI<35. CONCLUSION(S): BMI was not associated with intercourse compliance or noncompliance. An elevated BMI in infertile women with PCOS is not associated with poor intercourse compliance.

Total testosterone assays in women with polycystic ovary syndrome: precision and correlation with hirsutism.

CONTEXT: There is no standardized assay of testosterone in women. Liquid chromatography mass spectrometry (LC/MS) has been proposed as the preferable assay by an Endocrine Society Position Statement. OBJECTIVE: The aim was to compare assay results from a direct RIA with two LC/MS. DESIGN AND SETTING: We conducted a blinded laboratory study including masked duplicate samples at three laboratories--two academic (University of Virginia, RIA; and Mayo Clinic, LC/MS) and one commercial (Quest, LC/MS). PARTICIPANTS AND INTERVENTIONS: Baseline testosterone levels from 596 women with PCOS who participated in a large, multicenter, randomized controlled infertility trial performed at academic health centers in the United States were run by varying assays, and results were compared. MAIN OUTCOME MEASURE: We measured assay precision and correlation and baseline Ferriman-Gallwey hirsutism scores. RESULTS: Median testosterone levels were highest with RIA. The correlations between the blinded samples that were run in duplicate were comparable. The correlation coefficient (CC) between LC/MS at Quest and Mayo was 0.83 [95% confidence interval (CI), 0.80-0.85], between RIA and LC/MS at Mayo was 0.79 (95% CI, 0.76-0.82), and between RIA and LC/MS at Quest was 0.67 (95% CI, 0.63-0.72). Interassay variation was highest at the lower levels of total testosterone (≤50 ng/dl). The CC for Quest LC/MS was significantly different from those derived from the other assays. We found similar correlations between total testosterone levels and hirsutism score with the RIA (CC=0.24), LC/MS at Mayo (CC=0.15), or Quest (CC=0.17). CONCLUSIONS: A testosterone RIA is comparable to LC/MS assays. There is significant variability between LC/MS assays and poor precision with all assays at low testosterone levels.

Predictors of pregnancy in women with polycystic ovary syndrome.

CONTEXT: Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. The selection of first-line therapies for ovulation induction is empiric. OBJECTIVE: The aim of the study was to develop a clinically useful predictive model of live birth with varying ovulation induction methods. DESIGN, SETTING, AND PARTICIPANTS: We built four prognostic models from a large multicenter randomized controlled infertility trial of 626 women with PCOS performed at academic health centers in the United States to predict success of ovulation, conception, pregnancy, and live birth, evaluating the influence of patients' baseline characteristics. INTERVENTIONS: Ovulation was induced with clomiphene, metformin, or the combination of both for up to six cycles or conception. MAIN OUTCOME MEASURE: The primary outcome of the trial was the rate of live births. RESULTS: Baseline free androgen index, baseline proinsulin level, interaction of treatment arm with body mass index, and duration of attempting conception were significant predictors in all four models. History of a prior loss predicted ovulation and conception, but not pregnancy or live birth. A modified Ferriman Gallwey hirsutism score of less than 8 was predictive of conception, pregnancy, and live birth (although it did not predict ovulation success). Age was a divergent predictor based on outcome; age greater than 34 predicted ovulation, whereas age less than 35 was a predictive factor for a successful pregnancy and live birth. Smoking history had no predictive value. CONCLUSIONS: A live birth prediction chart developed from basic clinical parameters (body mass index, age, hirsutism score, and duration of attempting conception) may help physicians counsel and select infertility treatments for women with PCOS.

Medication adherence and treatment success in the National Institute of Child Health and Human Development-Reproductive Medicine Network's Pregnancy in Polycystic Ovary Syndrome Trial.

We investigated whether poor adherence with metformin tablets may have contributed to the poor success rates seen in the metformin-containing arms of the Pregnancy in Polycystic Ovary Syndrome (PPCOS) Trial. Median adherence for both metformin and clomiphene citrate tablets was within acceptable limits and unrelated to ovulation: thus, failure to comply with physician recommendations for metformin dosing was not the reason for low ovulation and pregnancy rates in the PPCOS Trial.

Metabolic and ovarian effects of rosiglitazone treatment for 12 weeks in insulin-resistant women with polycystic ovary syndrome.

BACKGROUND: Insulin sensitizers have favourable metabolic and ovarian effects in polycystic ovary syndrome (PCOS). This study examined rosiglitazone, a thiazolidinedione, in PCOS. METHODS: In a prospective, open-label study, the effects of rosiglitazone on metabolism and ovarian function were examined in 42 non-diabetic women with PCOS classified according to the National Institute of Child Health and Human Development criteria and insulin resistance (IR) by steady-state plasma glucose (SSPG) > or =10 mmol/l on octreotide-modified insulin suppression testing. Participants were randomized to rosiglitazone 2, 4 or 8 mg daily for 12 weeks. Endpoints included ovulation and menstrual pattern; serum testosterone, sex hormone-binding globulin (SHBG), and LH; and changes in IR and glucose-insulin responses on 8 h mixed-meal profile. RESULTS: After rosiglitazone 8 mg daily for 12 weeks, SSPG declined and insulinaemia fell by 46%; lower doses gave lesser effects. Serum LH, total and free testosterone were unchanged; SHBG increased. With rosiglitazone, ovulation occurred in 23/42 women (55%), without significant dose dependence. Both before and during treatment, ovulators on rosiglitazone had lower circulating insulin and free testosterone and higher SHBG than non-ovulators. Testosterone declined only in a subgroup of ovulators with early vaginal bleeding after starting rosiglitazone. CONCLUSIONS: Rosiglitazone in insulin-resistant PCOS promoted ovulation and dose-dependently decreased IR and insulinaemia; ovulators had lower circulating insulin and testosterone.

The Pregnancy in Polycystic Ovary Syndrome study: baseline characteristics of the randomized cohort including racial effects.

OBJECTIVE: To report the baseline characteristics and racial differences in the polycystic ovary syndrome (PCOS) phenotype from a large multicenter clinical trial (PPCOS). DESIGN: Double-blind, randomized trial of three treatment regimens (with extended release metformin or clomiphene citrate). SETTING: Academic medical centers. PATIENT(S): Six hundred twenty-six infertile women with PCOS, aged 18-39 years, with elevated T levels and oligomenorrhea (exclusion of secondary causes), seeking pregnancy, with > or = 1 patent fallopian tube, normal uterine cavity, and a partner with sperm concentration > or = 20 x 10(6)/mL in > or = 1 ejaculate. INTERVENTION(S): Baseline characterization. MAIN OUTCOME MEASURE(S): Historical, biometric, and biochemical measures of PCOS. RESULT(S): There were no significant differences in baseline variables between treatment groups. The overall mean (+/-SD) age of the subjects was 28.1 +/- 4.0 years, and the mean body mass index was 35.2 kg/m2 (+/-8.7). Polycystic ovaries (PCOs) were present in 90.3% of the subjects, and the mean volume of each ovary was 10 cm3 or more. Of the subjects, 7% had ovaries that were discordant for PCO morphology. At baseline, 18.3% of the subjects had an abnormal fasting glucose level (> 100 mg/dL). Asians tended to have a milder phenotype, and whites and African Americans were similar in these measures. CONCLUSION(S): The treatment groups were well matched for baseline parameters, and we have added further information to the PCOS phenotype.
