5. Birth defects & miscarriages are well established
Thu Apr 9, 2026, 05:01 PM

It's not debatable about increasing birth defects and miscarriages with advanced age.

Miscarriage
All women are at risk for miscarriage. However, this risk increases when women are over the age of 35. Risk of miscarriage in women ages 20–30 is 8.9% versus 74.7% in women over age 40.2
Genetic abnormalities

The overall risk of having a baby with chromosomal abnormality is small, but the rates increase with maternal age. The most common abnormality is Down syndrome or trisomy 21. At age 20, the risk of having a baby with Down syndrome is 1 in 1,480 pregnancies, versus 1 in 353 pregnancies at age 35, versus 1 in 35 at age 45.3 Prenatal screening and diagnostic tests are available and offered for all pregnancies. Genetic testing is available to screen mother, father, and fetus for common genetic disorders. Having a discussion with your physician is important.
