New Tool Decodes Chromosome Issues in Older Women's Eggs
Human egg cells are frequently susceptible to chromosomal mistakes, and these errors rise dramatically as women age. This increase contributes to infertility, pregnancy loss, and various genetic disorders. The precise reason for this sharp escalation has long remained unclear.
Researchers at Yale have made progress toward solving this mystery. In a recent study published in Nature Aging, the team unveiled a fast and flexible technique for recreating aging-like chromosomal problems in mouse eggs without waiting for natural aging to occur.
"Using this method, scientists were able to observe how multiple cellular malfunctions lead to chromosomal errors that become more frequent with maternal age."
The study identified that a mix of factors—including the partial loss of key proteins and weakened links between chromosomes—plays a major role in error formation. This innovative method, researchers believe, could eventually help in studying and preventing chromosomal abnormalities in the eggs of older women.

The Yale study introduces a rapid experimental model that mimics age-related chromosomal errors in eggs, paving the way for future fertility and genetic research.
