The fertility of women drops as a woman ages. It starts dropping significantly when a woman is around age 35 but why do this happen?

According to a research published in the Daily Mail, chromosomal defect in the eggs of older women could be the cause behind fertility problems in older women.

Scientists claim a biological structure that separates chromosomes in the eggs of older women sends the chromosomes all over the place instead of distributing them evenly to each egg.

“An egg typically has 46 chromosomes, and having more than 46 is the cause behind Down syndrome, while having too few will likely end in miscarriage,” a report in Daily Mail claims.

An egg that has more than 46 chromosomes is called an aneuploid egg and eggs are more likely to be aneuploid with age because the “glue” that keeps the chromosomes together works poorly in older eggs.

The report also revealed that “women are born with a fixed number of eggs, which remain dormant in the ovaries until the release of a single egg per menstrual cycle.”
