Ultrasound Guided Embryo Transfer: Abdominal Versus Transvaginal, a RCT

Ultrasound (US) guided embryo transfer (ET) appears to improve pregnancy outcomes in IVF-ET. Most reports are done using a transabdominal (TAS) approach, in contrast to a transvaginal ultrasound (TVS) which does not require a full bladder. We sought to determine if either approach was better with respect to clinical outcomes.
