AMH levels rise in women with PCOS and may play a role in the pathophysiology of this syndrome [35], as AMH inhibits the recruitment of primordial follicles, decreases the follicular sensitivity to FSH, and inhibits granulosa cell aromatase, leading to an increase in intrafollicular androgen levels [14, 36]. This evidence concerns the gene CYP19A1 and polycystic ovary syndrome.
