Day of blastulation correlates with ploidy status and serves as a useful non-invasive parameter for ranking embryos from non-PGT-A patients for transfer

BACKGROUND AND AIM Embryologists continue to strive to establish non-invasive parameters for ranking embryos to prioritize the ones with the highest chance of pregnancy success. Embryo morpho-kinetics have been correlated with implantation success. Previous studies have demonstrated that day 5 blastocysts result in higher implantation and pregnancy success as compared to day 6 blastocysts [1,2]. We aimed to test the hypothesis that embryos …
