Melado Vidales et al. (2017a)demonstrated serum AMH levels on hCG trigger day were correlated with the number oftop-quality embryos obtained in all the patients studied. The same authors, however,found no significant between-group differences for AMH levels in FF nor for FR,number of TQE or implantation rates when comparing PCOS patients to patients withlow/normal ovarian reserve (Melado Vidaleset al., 2017b). This evidence concerns the gene AMH and polycystic ovary syndrome.
