Medical experts continue to provide guidance on the biological realities and health considerations of pregnancy and fertility in older age, noting an increasing trend of pregnancies in women aged 40 and older due to shifts in education, career, and social life.

While specialists emphasize that age is not an absolute barrier, they highlight specific biological challenges. The decline in ovarian reserve and egg quality increases the likelihood of chromosomal abnormalities, which can lead to difficulties in embryo implantation or higher miscarriage rates. Experts clarify that while tests such as Anti-Müllerian Hormone (AMH) and antral follicle counts can provide information on ovarian reserve, they do not independently indicate egg quality.

To manage risks, medical professionals recommend thorough pre-pregnancy evaluations, including monitoring blood pressure, blood sugar, and thyroid function. For women over 35, specialists recommend starting diagnostic testing after six months of regular attempts to conceive, while those over 40 are advised to seek immediate consultation. Close, personalized monitoring during pregnancy is also advised to manage potential complications such as gestational diabetes and hypertension.

Recent discussions from specialists, including those in Chile, emphasize evolving approaches to obstetric care. Dr. Alicia Álvarez advocates for viewing pregnancy not as an illness and suggests that maintaining an active lifestyle is beneficial in uncomplicated cases. Furthermore, advancements in prenatal diagnosis, such as improved ultrasound and screening techniques, allow for earlier identification of complications. Academic María Mondaca stresses that while risks like hypertension and chromosomal alterations increase after age 40, these must be evaluated individually through professional counseling to help women make informed decisions.
