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 in patients with repeated implantation failure.
Methods: This was a retrospective cohort study which was conducted in a
University affiliated private hospital. The study included 135 patients with
repeated implantation failure who underwent single, autologous euploid ERA
adjusted and non-adjusted FET. Patients were stratified into three groups,
patients with receptive endometrium based on the ERA test, patients with
non-receptive endometrium based on the ERA test and patients who did not receive
the ERA test (control group). The three groups were compared in terms of FET
outcomes. Results: Of 135 patients, 73 had the ERA test results
available and 62 did not have the ERA test. Of 73 patients, 28 had non-receptive
endometrium and 45 had receptive endometrium. The three groups are all the same
in terms of age, body mass index, type of infertility, duration of infertility,
number of previously embryo transfers and infertility causes (p
