Ultrasound Guided Embryo Transfer: Abdominal Versus Transvaginal, a RCT

Completed

• Conditions: Infertility; in Vitro Fertilization

• Registration Number: NCT00682071
• Lead Sponsor: University of Wisconsin, Madison

Brief Summary

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.
