Do basal inhibin A and inhibin B levels have value in the diagnosis of polycystic ovary syndrome?
In the present study we aimed to investigate whether basal inhibin A and B levels in women with polycystic ovary syndrome (PCOS) would be used in diagnosis of the condition. Forty women with PCOS and 40 women with normal cycles (control group) were evaluated. There was no statistically significant difference in mean age and mean body mass index between the two groups (p > 0.05). Serum levels of inhibin A and B, follicle-stimulating hormone (FSH), luteinizing hormone and total testosterone, and total ovarian volume, were determined in the PCOS group and the control group on day 3. In the PCOS group, total follicle number was obtained by counting follicles of diameter > or =2 mm in both ovaries. Results were evaluated using Student's t test, Pearson correlation and regression tests. There was no significant difference in mean basal inhibin A or inhibin B levels between the two groups. Basal inhibin B levels showed a statistically significant negative correlation with basal FSH levels and a positive correlation with total follicle number in the PCOS group (p < 0.05 and p < 0.01, respectively). We conclude that basal inhibin A or B levels cannot be used in the diagnosis of PCOS.
