A 2000 study in the Obstetrics and Gynecology journal showed a fetus has a high risk of sudden death in a woman over 40 as compared to a younger counterpart, reports WebMD. Advanced age may increase the risk of genetic conditions, such as Down’s syndrome. Experts say this occurs when a woman aged 45 and over becomes pregnant with her own eggs, according to Pregnancy & Baby. Even when a woman uses donor eggs, she is at risk of developing preeclampsia, which involves high blood pressure and fluid retention. Such a woman may also have a higher need for a cesarean section, reports CNN.

The risk of miscarriage tends to rise with advancing age, reports Mayo Clinic. While women aged 35 to 39 have a 25 percent chance of miscarriage, those aged 40 and over have a 51 percent risk. A fetus may also experience growth retardation and have heart defects, according to WebMD.
