Relationship between serum anti-Mullerian hormone and clinical parameters in polycystic ovary syndrome

[摘要] Polycystic ovary syndrome (PCOS) is an ovulatory disorder that affects 6-10% of women of reproductive age.Serum AMH level may be an additional factor, or surrogate of PCOM, in the diagnostic criteria of PCOS.We evaluated the correlations between the serum AMH level and various endocrine and metabolic features in PCOS using the latest fully automated assay.Serum AMH level was compared between 114 PCOS patient (PCOS group) and 95 normal menstrual cycle women (Control group).Correlations between serum AMH level and various endocrine and metabolic factors were analysed in PCOS group.The serum AMH level was significantly higher in the PCOS group (8.35±8.19 ng/mL) than in the Control group (4.99±3.23 ng/mL).The serum AMH level was independently affected by age and the presence of PCOS on multiple regression analysis.Ovarian volume per ovary (OPVO) showed the strongest positive correlation (r=0.62) with the serum AMH level among related factors.On receiver operating characteristic (ROC) curve analysis, the cut-off value of AMH for the diagnosis of PCOS was 7.33 ng/mL, but this value did not have high efficacy (sensitivity 44.7%, specificity 76.8%).A cut-off value of 10 ng/mL had a high specificity of 92.6%, although the sensitivity was low (24.6%).The serum AMH level was elevated and reflected ovarian size in PCOS patients.The serum AMH level could be a surrogate for ultrasound findings of the ovaries in PCOS and might be useful for estimating ovarian findings without transvaginal ultrasound in the diagnosis of PCOS.
