Cytogenetic and Microarray Analysis Follow‐Up of PGT‐A Mosaic and Sex Discrepant Embryos During Pregnancy: Absence of Confirmation and Follow‐Up Recommendations

This work emphasizes the importance of PGT-A follow-up and demonstrates that the vast majority will have normal diagnostic results and only a small number will be confirmed using prenatal diagnostic analysis. This work also suggests the most efficient way to proceed with diagnostic follow-up studies. Additionally, it shows the importance of fetal sex confirmation in all normal PGT-A studies.
