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

Key Points

• This work aims to evaluate the follow-up of PGT-A mosaic and sex-discrepant embryos during pregnancy.
• Examined diagnostic results of PGT-A mosiac and sex-discrepant embryos.
• Utilized cytogenetic and microarray analysis techniques.
• Emphasized fetal sex confirmation in normal PGT-A evaluations.
• Most embryos from PGT-A show normal diagnostic results.
• Only a small percentage of embryos were confirmed through prenatal diagnostics.
• Fetal sex confirmation is crucial across all normal PGT-A evaluations.
