Advantages of Serum Anti-Müllerian Hormone as a Marker for Polycystic Ovarian Syndrome.

OBJECTIVE: To evaluate the advantages of using anti-Müllerian hormone (AMH) in the diagnosis of polycystic ovary syndrome (PCOS).

METHODS: We compared data from 56 Han Chinese patients with PCOS and 52 female control Han Chinese individuals in terms of biochemical markers and the antral follicle count (AFC). Then, the correlation between serum AMH levels and various endocrine and metabolic factors was analyzed. We generated receiver operating characteristic (ROC) curves to assess the usefulness of AMH, AFC, the luteinizing hormone/follicle-stimulating hormone (LH/FSH) ratio, and testosterone (T), to discriminate between the PCOS and control groups.

RESULTS: The LH/FSH ratio, homeostatis model assessment of insulin resistance (HOMA-IR), testosterone (T), blood glucose (Glu), triglyceride (TG), body mass index (BMI), AFC and, in particular, serum AMH level were significantly higher in the PCOS group than in the control group (P <.05; P <.001). The serum AMH level had a significant positive effect on the likelihood of AFC changes in patients with PCOS and control-group women. The areas under the ROC curve (AUC) of AMH, AFC, LH/FSH ratio, and T were 0.952, 0.778, 0.760, and 0.665, respectively. The best cutoff point for AMH was 6.09 ng per mL, with sensitivity of 88% and specificity of 88%.
