AMH and polycystic ovary syndrome: The number of available embryos and top-quality embryos were also higher, but not significantly, in Group B. This could be explained: first, the incidence of PCOS was higher in patients with AMH > 4.7 ng/ml, and the oocyte quality in those patients might be influenced by endocrine and intra-ovarian paracrine changes in follicular fluid (40); second, compared to patients with AMH levels between 1.1 and 4.7 ng/ml, there might be a higher proportion of immature oocytes obtained in patients with AMH > 4.7 ng/ml (41).
