PREGNANCY OUTCOMES BY DEGREE OF EXPANSION IN THAWED HIGH QUALITY EMBRYOS

Abstract

Identifying factors predictive of success in embryo transfer cycles has long been a goal in the field of reproductive medicine. Numerous studies that have identified morphokinetic parameters associated with clinical pregnancy and live birth have highlighted the importance of embryo monitoring. This current study set out to investigate the effect of the degree of embryo expansion post thaw on clinical pregnancy rates as part of a quality improvement project. Clinical pregnancy rates were compared based on the degree of expansion post thaw.
