The decrease in egg quality with maternal age leads to an increase in aneuploidy (alterations in the number of chromosomes). These alterations mean an increased risk of spontaneous miscarriage, as well as an increased likelihood of having babies with Down syndrome (for example).
However, there are other risks when a woman becomes pregnant after the age of 30:
- Delayed fetal growth.
- Gestational diabetes.
- Preterm labor.
- Risk of cesarean section.
- Ectopic pregnancy.
Therefore, it is very important to assess these disadvantages when postponing childbearing until after the age of 30.
