IMPLANTATION TIMING AFTER EMBRYO TRANSFER IS DIFFERENT FROM EMBRYO CHARACTERISTICS

Abstract

In recent years, the optimal timing of embryo transfer can be obtained by the endometrial receptivity analysis (ERA). Although the clinical use of ERA has improved implantation rate after embryo transfer (ET) in many cases, several cases still have resulted in failure. Therefore, we have built the hypothesis that the implantation timing after embryo transfer may differ from the embryo characteristic. The aim of this study is to evaluate the implantation timing after ET based on embryo characteristics.
