Only women under 42years were included, without uterine malformations, submucosal myomas oruntreated hydrosalpinx (Hou etal., 2020; Lanet al., 2021; Wuet al., 2022; Geet al., 2023), although the study by Hou et al. (2020) had morerestrictive criteria and only considered women under 38 and with good ovarianreserve (basal FSH<10 mU/mL, and AFC above 10). This evidence concerns the gene BRD2 and Abnormality of the uterus.
