INTRODUCTION Polycystic ovary syndrome (PCOS) is one of the most common causes of anovulation, infertility and hyperandrogenism, and the prevalence of this condition in women of reproductive is 5-10%. The growth of early ovarian antral follicles is arrested and dominant follicle selection is disturbed in this syndrome. OBJECTIVE The aim of this study is to investigate whether inhibin B serum concentrations represent the extent of ovarian abnormalities in patients with PCOS. METHOD Inhibin B serum concentrations on the third day of spontaneous menstrual cycle and other endocrine characteristics were compared between 20 patients with PCOS and 19 healthy women in the control group. RESULTS Inhibin B concentrations were not significantly different between women with PCOS and women in the control group. In patients with PCOS there was statistically significant correlation between serum inhibin B and LH (r=0.514; p=0.021). There were no positive correlations between inhibin B and others endocrine parameters in patients with PCOS (FSH, E2, T, androstenedione). CONCLUSION Inhibin B serum concentrations on the third day of spontaneous menstrual cycle in women with PCOS are not different from the concentrations in healthy women. Serum Inhibin B levels in patients with PCOS are only slightly correlated with the endocrine markers of the disease so it could not represent the magnitude of ovarian dysfunction in this syndrome.

The Relationship

OBJECTIVE: Polycystic ovary syndrome (PCOS) is characterized by ovarian dysfunction. Although the role of leptin in the control of reproduction is unclear, it may be involved in the control of ovulation. The aim of this cross-sectional study was to determine the relationship between circulating leptin concentrations, and anthropometric, metabolic and endocrine variables as well as to examine a possible role of leptin in ovarian dysfunction associated with PCOS. DESIGN: Prospective observational study. METHODS: Seventy-one subjects with PCOS and 23 body mass index (BMI)-matched control subjects were recruited from infertility clinics. The association between serum leptin concentrations and the above variables was measured outwith the luteal phase. A subgroup of 24 PCOS subjects underwent more frequent blood sampling to monitor follicular growth and ovulation. The association between variables was measured by univariate, multivariate and partial correlation analyses. RESULTS: Serum leptin concentrations were not different in subjects with PCOS and controls, and were strongly associated with BMI in both groups. Twelve patients ovulated during the study period. There was no significant difference in serum leptin concentrations between ovulatory and anovulatory subjects. The relationship between BMI and leptin was similar in both groups. CONCLUSION: The results indicated that circulating leptin concentrations relate principally to total body fat in subjects with PCOS and controls, and that this is not associated with the facility for follicular development and ovulation in these patients.
