Previous studies demonstrated that miR-223-3p played a role in endometrial receptivity by regulating leukemia inhibitory factor (LIF), miR-199b-5p was present in the follicular fluid of women with PCOS and correlated with AMH levels, miR-1244 was upregulated in the follicular fluid of infertile women leading to downstream events that affect fertilization, and miR-183-5p was involved in the regulation of uterine receptivity, enhancement of embryo implantation, and invasion and migration of trophoblast cells [52,53,54,55,56,57,58,59]. The gene discussed is AMH; the disease is polycystic ovary syndrome.
