Eight predictors were significant: 1) maternal physiology (maternal age at oocyte retrieval and serum AMH level), 2) uterine factor (adenomyosis), and 3) embryo assessment (number of fertilized embryos, blastocyst morphology, blastulation day, blastocyst re-expansion speed, and presence of an embryo string). The gene discussed is AMH; the disease is adenomyosis.
