Reproductive outcomes in single euploid embryo transfer cycles 18 independent of whether the embryo originated from a fresh or cryopreserved oocyte.

It is common practice in ART treatment to transfer frozen embryos derived from fresh oocytes. Yet, there is a growing subset of patients who are now returning to treatment and using cryopreserved oocytes to create embryos for transfer. Whether pregnancy rates are affected by the use of embryos developed from cryopreserved oocytes has not been fully assessed in ART literature. The goal of this study is to compare pregnancy outcomes from patients undergoing frozen, single euploid embryo transfers (SEETs) who used embryos developed from fresh oocytes compared to embryos created with cryopreserved oocytes.
