The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
University of Wisconsin, Madison
  Purpose
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.

Condition
Infertility in Vitro Fertilization

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective
Official Title: Abdominal Versus Transvaginal Ultrasound Guided Embryo Transfer: Results of a Randomized Clinical Trial
