Diagnostic value of prostate-specific antigen in women with polycystic ovary syndrome*

BACKGROUND Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women. Its presentation is that of irregular menstruation associated with ovulation defects. Because of adverse outcomes such as metabolic and cardiovascular disorders, its diagnosis and treatment is very important. Therefore, the diagnostic value of prostatespecific antigen (PSA) in women with polycystic ovary syndrome was evaluated. METHODS A total of 32 women with PCOS and 32 aged matched healthy females were recruited in this case-control study. The subjects were compared by means of metabolic measures and serum PSA level. The correlations between these markers were evaluated. Sensitivity and specificity values and cut off levels of PSA were established for diagnosis of PCOS. RESULTS Mean PSA, Ferriman Gallwey score (FGS), luteinizing hormone/follicle stimulating hormone ratio (LH/FSH), testosterone, dehydroepiandrosterone sulfate (DHEAS), 17(α) hydroxyprogesterone (17(α) HP) levels were significantly higher in PCOS (P<0.001, respectively). PSA levels greater than 0.07 ng/ml yielded a sensitivity of 91% and specificity of 82%, and was helpful as a diagnostic tool for women with PCOS. Circulating androgens and hirsutism were associated with higher levels of PSA in PCOS women. CONCLUSIONS Our results showed direct correlation between PSA, hirsutism and hyperandrogemsm state. Therefore, it seems logical to use PSA level for detection of hyperandrogemsm state in women.
