The ability to cryopreserve and genetically screen embryos has increased cumulative pregnancy rates and confidence in embryo banking. Compared to fresh ET cycles, endometrial receptivity and placentation appear to be enhanced by the more physiologic hormonal milieu of FET cycles. Whether the influence of vitrification-warming on the morphology of euploid blastocysts impacts their implantation potential is not well characterized. This study examines whether changes in morphology grading, after vitrification-warming, correlate with clinical outcome, using a study model controlling for endometrial environment and embryonic ploidy.
