Abstract
Objective: To estimate the correlation between the simplified SART embryo scoring system and ART cycle outcomes in single blastocyst transfers (SBT). Materials and Methods: All fresh, autologous SBT cycles from a large ART center from 2010 were analyzed. Blastocysts were given a single grade of good, fair, or poor based upon SART criteria. Multiple logistic regression assessed the impact of the SART grade on embryo implantation, clinical pregnancy, and live birth. Results: 720 fresh, autologous SBT cycles were analyzed. The overall live birth rate was 52% for the SBT cycles and included both elective and non-elective SBT. Chi square analysis showed higher live birth in good grade embryos as compared to fair (p=0.03) and poor (p=0.02). Univariate binary logistic regression analysis showed SART embryo grading to be significantly correlated with both implantation and live birth (p<0.01). The significance of the SART grade persisted when patient age and the stage of the blastocyst were controlled for with multiple logistic regression. Conclusion: The simplified SART embryo scoring system is highly correlated to implantation and live birth in SBT. Patients with a good grade are excellent candidates for a single blastocyst transfer.
