Anaysis of the association between chromosomal abnormalities in early missed abortion embryos and maternal age and AMH levels based on CNV-Seq

Increased maternal age and decreased AMH levels are closely associated with higher risk of chromosomal abnormalities in EMA embryos. As a sensitive indicator of ovarian reserve, AMH reflects oocyte quality and chromosomal stability, particularly in younger women. Combined assessment of maternal age and AMH may improve risk evaluation and inform preventive and intervention strategies for EMA.
