AMH and polycystic ovary syndrome: Fallat et al. (1997) demonstrated that immatureoocytes rate was higher in PCOS patients and Arabzadeh et al. (2010) found that, although the serumand FF AMH levels were higher in PCOS compared to normo-ovulatory controls, thepositive correlation between AMH concentrations and mature oocytes was fund only inthe control group. A prospective study by Ebneret al. (2006) divided patients according to theirAMH serum levels and found that serum AMH <1.66ng/mL and >4.52ng/mL wereassociated with oocytes of lower quality.
