Everywhere you look, there’s yet another new record for the world’s oldest mother, thanks to medical technology and the fact that today’s 40- and 50-year-olds are healthier than in the past.
But there are serious risks. Women older than 40 are more likely to have pregnancy problems such as preeclampsia, diabetes, premature birth, and a low birth weight baby, as well as placental problems. Read more about infertility and aging below.

According to the Society for Assisted Reproductive Technology, success rates for IVF decline dramatically after age 37, making age the most important factor for women who want to pursue pregnancy using their own eggs. After age 43, donated eggs from younger women are often required for successful pregnancy.
As a woman ages, the remaining eggs in her ovaries also age, making them less capable of fertilization and their embryos less capable of implanting. Only 12 percent of the 300,000 eggs a woman is born with remain at age 30, and only 9,000 eggs remain at age 40, though 3 percent are not viable. By the time a woman reaches menopause, usually between ages 50 to 55, there are only several thousand eggs remaining and their viability is questionable.
Older mothers face a higher risk of adverse conditions and complications for pregnancy, such as:
NOTE: aging also affects male fertility, but to a much lesser degree. It affects sperm quality and coital frequency, but there is no maximum age at which men are not capable of conceiving a child. Learn more about age-related male infertility.
