Is Endometrial Receptivity Assay (ERA) Useful in Patients with Repeated Implantation Failure Undergoing Single, Autologous Euploid Embryo Transfer?

Background: Our aim in this study was to evaluate whether endometrial receptivity assay (ERA) test improves single, autologous euploid frozen-thawed embryo transfer (FET) outcomes patients with repeated implantation failure. Methods: This a retrospective cohort which conducted University affiliated private hospital. The included 135 failure who underwent ERA adjusted and non-adjusted FET. Patients were stratified into three groups, receptive endometrium based on the test, non-receptive did not receive (control group). groups compared terms of FET outcomes. Results: Of patients, 73 had results available 62 have test. 28 45 endometrium. are all same age, body mass index, type infertility, duration number previously transfers infertility causes (p > 0.05). Live birth rates 46%, 50% 51% for receptive, control respectively Implantation clinical pregnancy similar between as well. Conclusions: Adjusting day according seems improve
