Objective: The aim of this study was to evaluate differences in anti-müllerian hormone (AMH) and insulin-like 3 (INSL3) levels and their association with gonadotropin and ovarian steroid hormones, as expression of ovarian function, between healthy normal-weight ovulatory and anovulatory eumenorrheic late adolescent females.Study Design: This study analyzed AMH and INSL3 levels in forty healthy eumenorrheic late adolescent females (aged 16-19 ys), selected from a cross-sectional epidemiological study performed on the prevalence of hyperandrogenic states. The subjects were divided into ovulatory (n: 28) and anovulatory (n: 12) groups in accordance to a previous cluster analysis based on progesterone (P) distribution measured once in the latter part of the cycle. Both groups were compared for anthropometric, biochemical and hormonal parameters.Results: INSL3 and AMH were detectable in all samples. Testosterone (P=0.01), the free-androgen index (FAI) (P=0.051), gonadotropins (LH: P=0.02; FSH: P=0.004) and AMH (P=0.02) levels were significantly higher in the anovulatory group with respect to their ovulatory counterpart. A trend toward significantly higher INSL3 concentrations (P=0.08) was also shown in the anovulatory group. A positive correlation between INSL3 levels and androgens such as androstenedione (r=0.38; P=0.02), testosterone (r=0.44; P=0.004) and FAI (r=0.42; P=0.006) and a negative borderline significant correlation (r=-0.30; P=0.055) between AMH and P were shown in all subjects.Conclusion: Healthy eumenorrheic late adolescent females with sporadic anovulation display higher AMH and INSL-3 blood concentrations in association with higher androgen levels compared with age- and BMI-matched subjects with ovulatory cycle, suggesting evidence of an earlier ovarian dysfunction.
