A new tool for understanding chromosome abnormalities in the eggs of older women
Human egg cells are often prone to chromosomal errors. As women age, the error rate increases sharply—and can contribute to infertility, pregnancy loss, and genetic disorders. Yet why this sudden rise happens remains unknown.
