Morphology plus ploidy: a prospective study comparing traditional morphology-based selection for single embryo transfer (SET) with comprehensive chromosome screening (CCS) results

      Elective SET using morphologic selection criteria has resulted in reduced delivery rates compared to double embryo transfer in all RCTs to date, reflecting the inability to accurately assess reproductive potential. Given that high-quality blastocysts are more likely to be euploid, it is not known how often adding CCS would alter embryo selection for SET. This study sought to determine the proportion of morphologically-selected embryos for SET that were aneuploid.
