The value of anti-Mullerian hormone in the management of polycystic ovary syndrome in adolescents

Abstract

A prospective study was carried out in 110 adolescents (13–19 years), 90 patients with polycystic ovary syndrome (PCOS) (study group) and 20 healthy adolescents (control group). The study group was divided into two: Group I – patients without insulin resistance (n = 30) and Group II – patients with insulin resistance (n = 60). Group I was treated with oral contraceptives (OCs), while Group II was divided into treatment subgroups of 20 patients each: Subgroup A received OCs; Subgroup B − myo-inositol; subgroup C – OCs + myo-inositol. Data were analyzed at baseline, 3 and 6 months of treatment. Results showed average anti-Mullerian hormone (AMH) levels were significantly higher in PCOS patients (11.8 ± 5.3 ng/ml) than in controls (2.98 ± 4.5 ng/ml). After treatment, in Group I and Group II Subgroup A: AMH, luteinizing hormone (LH), free testosterone (FT), total testosterone (T), Ov/v, antral follicle count (AFC), and Ferriman–Gallwey modified scale (mFG) significantly decreased, homeostatic model assessment-insulin resistance (HOMA-IR), body mass index (BMI) did not change significantly. In Group II Subgroup B only HOMA-IR and BMI significantly decreased; in Subgroup C all the parameters decreased significantly. The correlation between AMH and hormonal, morphological characteristics of ovaries were established. The results indicate that AMH could possibly be a valuable marker for the diagnosis of PCOS in adolescents, and for the assessment of treatment efficacy as well.
