Anti-Mullerian hormone (AMH) as a useful marker in diagnosis of polycystic ovary syndrome

Acta Endo (Buc) 2007, 3 (1): 1-12

The mechanism underlying anovulation in the polycystic ovary syndrome (PCOS) remains unclear, although an excessive number of small antral follicles at ultrasound scans and discrepancies with selected follicles sustain the hypothesis of altered follicular development. Anti-M?llerian (AMH) hormone is a member of TGF-b super family of growth factors produced by granulosa cells of pre- and small-antral follicle. The 2 to 3 fold increase in the number of growing follicles in the ovary from PCOS women is reflected by an increase in serum concentration of AMH and thus, this hormone may be a good marker of PCOS.\r\nAim. This study was intended to implement ultra-sensitive ELISA measurement of serum AMH from PCOS women and search for a potential correlation with clinical and laboratory parameters.\r\nSubjects and methods. Sera from patients with PCOS (n = 42) and control women (n = 22) were used for ELISA measurement of AMH (AMH-EIA, Beckman Coulter) with sensitivity of 0.7 pmol/L.\r\nResults. We found a serum concentration of AMH almost 3 folds higher in patients with PCOS compared to controls (73.7 ? 7.5 vs. 25.7 ? 3.9 pmol/L, P < 0.0001). Differences were even higher in lean subjects. A positive correlation was found between total testosterone and LH levels, but not with serum FSH or insulin. Moreover, AMH concentration was correlated to more hyperandrogenic PCOS and with amenorrhea, and thus to the severity of the syndrome.\r\nConclusion. Measurement of serum AMH may be used as a valuable marker for PCOS to confirm diagnosis and evaluate the extent of follicular dysfunction in relation with hyperandrogenism and menstrual disturbances.
