Why is down syndrome more common in older mothers? A woman’s chances of giving birth to a child with Down syndrome increase with age because older eggs have a greater risk of improper chromosome division. A woman’s risk of conceiving a child with Down syndrome increases after 35 years of age.
Why do older mothers have higher risk of Down syndrome? By the time a woman reaches 40, as many as 60 percent of her eggs will contain an abnormal number of chromosomes. In other words, chromosomal abnormalities are more likely to develop in the eggs of older women.
