BRD2 and Infertility: The no euploid blastocysts group were more likely to have (1) less number of pregnancy loss, (2) a longer duration of infertility, (3) more nonfirst cycles, (4) higher basal serum FSH, (5) less classical long protocol of controlled ovarian hyperstimulation, and (6) less number of oocytes retrieved, less number of mature (MII) oocytes retrieved, less number of embryos per oocyte retrieval, less number of high-quality embryos per oocyte retrieval and less number of blastocysts than at least 1 euploid blastocysts group (P < 0.05).
