Hysteroscopic Endometrial Fundal Incision versus Hysteroscopy Only in Oocyte Recipients: A Randomized Controlled Trial Assessing The Reproductive Outcomes.

EFI during hysteroscopy seems to improve pregnancy rates in oocyte recipients without intrauterine pathology, while live birth rates are not affected by the EFI. These results should be interpreted with caution before the implementation of EFI in the routine in vitro fertilization (IVF) practice (registration number: NCT04580056).
