Prevention of in  vitro fertilization twins should focus on maximizing single embryo transfer versus twins are an acceptable complication of in vitro fertilization

Twin pregnancy is an iatrogenic complication of in  vitro fertilization (IVF) associated with severe as well as subtle adverse outcomes (1). With higher implantation rates (IRs) and refined cryopreservation protocols for extra embryos (2), many centers like ours worldwide have made single embryo transfer (SET) the default choice for most IVF couple s. When accompanied by preimplantation genetic screening, elective SET (eSET) pregnancy rates at all ages have reached 50% or higher (3), whereas double embryo transfer (DET) would carry an unacceptable risk of twins.
