Abstract Endometrial receptivity (ER)is one of the main reasons affecting the success rate of assisted reproductive technology. According to statistics, embryonic factors account for one third of implantation failures of embryo, and ER account for the other two thirds. Endometrium in non-receptive period will affect the implantation of fertilized eggs, which will lead to infertility and reduce the success rate of assisted reproductive technology. In recent years, with the continuous development of assisted reproductive technology, great breakthroughs have developed in the improvement of embryo detection methods. However, there is no uniform standard for evaluating ER. This article reviews the values of the endometrial morphology, ultrasonic, and ER array for evaluating ER.
