Advanced maternal age (AMA) and pregnancy: a feasible but problematic event.

This narrative review aimed to summarize all adverse outcomes of pregnancy in advanced maternal age (AMA) to assess the age of the mother as a potentially crucial risk factor. AMA refers to women older than 35 years. While expectations and the role of women in society have undergone significant changes today, the biology of aging remains unchanged. Various pathologic changes occur in the human body with age, including chronic noncommunicable diseases, as well as notable changes in reproductive organs, that significantly affect fertility. Despite substantial advancements in technology and medicine, pregnancy in AMA remains a formidable challenge. Although there are some advantages to postponing childbirth, they primarily relate to maternal maturity and economic stability. However, regrettably, there are also many adverse aspects of pregnancy at advanced ages. These include complications affecting both the mother and the fetus. Pregnants in AMA were more prone to suffer from gestational diabetes mellitus, preeclampsia, and eclampsia during pregnancy compared to younger women. In addition, miscarriages and ectopic pregnancies were more prevalent. Delivery was more frequently completed via cesarean section, and postpartum complications and maternal mortality were also higher. Unfortunately, there were also complications concerning the fetus, such as chromosomal abnormalities, premature birth, low birth weight, admission to the neonatal intensive care unit, and stillbirth.
