In our cohort of women with PCOS undergoing assisted reproduction, LBR was significantly higher in the low serum AMH group (< 3.32 ng/ml, 65.2%) than those with average (3.32–8.27 ng/ml, 46.7%) or high serum AMH levels (> 8.27 ng/ml, 43.5%). This evidence concerns the gene AMH and polycystic ovary syndrome.
