Efficacy of the endometrial receptivity array for repeated implantation failure in Japan: A retrospective, two‐centers study

Abstract

For patients with unexplained RIF, there is a significance in searching for their personal window of implantation (WOI) using the ERA, considering the percentage of those who were NR and the pregnancy rates that resulted from the pET. By transferring euploid embryos in a personal WOI, much better pregnancy rates are expected.
