Abstract: Assisted reproductive technology (ART) is one of the most important therapeutic measures for infertile couples, and embryonic implantation is one of the pivotal taches for the successful pregnancy of ART. Embryonic implantation is defined as the procedure of embryonic adhering and intruding into endometrium, so the uterine cavity and endometrium are very important for successful embryonic implantation and pregnancy. Abnormalities of uterus, including those congenital abnormalities and posteriority pathological states, could result in the failing embryonic implantation and pregnancy. In this review, those uterine factors related to the outcomes of ART were summarized, including thin endometrium, endometrial polyps, intrauterine adhesion, uterine fibroids, adenomyosis, endometrial peristalsis wave, uterine malformations and endometrial blood flow perfusion, so as to investigate the embryonic implantation and to improve the clinical outcomes of ART.
