1% XY proportion at ongoing pregnancy/delivery. Our models indicate a weaker association between blastocyst morphology parameters and sex proportion of babies in non-PGT-A cycles. Blastocyst features associated with a skewed sex proportion towards XY embryos, such as biopsy on day 5 and top quality TE, are also parameters used for selecting euploid embryos for SET. Therefore, our data suggest that morphology-based embryo selection represents a strong factor responsible for a skewed male sex proportion at birth in PGT-A cycles. Blastoc
