O-261: Implementation of elective single blastocyst transfer significantly decreases the incidence of multiple gestation without affecting overall and clinical pregnancy rates compared to double blastocyst transfer

Abstract

To evaluate the effect of implementing an elective single blastocyst transfer (eSBT) program on pregnancy outcome, multiple pregnancy rates (twins), and the frequency of double embryo transfers (DBT) during the first 18 months of practice in an IVF program. Although the benefits of reduced multiple pregnancy rates of eSBT are apparent, hesitancy to adopt this practice is predicated on the concern for reducing pregnancy success. During the incipience of this center’s blastocyst transfer (BT) program in 2002, all patients qualifying for BT exclusively underwent DBT (1/02 to 9/04) due to concerns for the potential reduction of success with transfer of one blastocyst (SBT).
