Endometrial volume measured on the day of embryo transfer is not associated with live birth rates in IVF: A prospective study and review of the literature.

Objective: To evaluate the effect of endometrial volume (EV) on the live birth rates (LBR)s in fresh or frozen embryo transfer (ET) cycles.

Material And Methods: This is a prospective study including all women who underwent a fresh or frozen single blastocyst transfer between January 2017 and September 2018 in a university affiliated private hospital. Patients with advanced age (>42years), congenital uterine anomalies, endometrial or myometrial abnormalities, those with a difficult ET, those with only poor-quality blastocysts available for transfer, those in whom an optimal 3D TVUS image could not be obtained and those who were lost to follow-up were excluded.
