“Advanced maternal age” is the clinical label for a pregnancy in which you will be 35 or older on your due date. It is not a diagnosis. It is a category that flags risks worth watching more closely, and the honest summary is that most pregnancies after 35 are healthy.
The threshold has a dated history. It was set decades ago because 35 was roughly the age at which the risk of a chromosomal condition matched the risk of amniocentesis. Testing has changed completely since then, so that math no longer applies. In its 2022 guidance on pregnancy at age 35 or older, the American College of Obstetricians and Gynecologists (ACOG) points out that 35 is an arbitrary cutoff and that several risks do not become clinically meaningful until closer to 40.
Conceiving Takes Longer, on Average
Fertility declines gradually through your 30s and more sharply after 37, driven by both the number and quality of remaining eggs. Miscarriage rates also rise, largely because of chromosomal errors in the egg.
So the usual advice to try for a year before seeking help shifts. If you are 35 or older, most specialists recommend an evaluation after six months of trying, and sooner if your cycles are irregular or you have a history of pelvic surgery or endometriosis.
Genetic Screening Is Offered to Everyone Now
The old rule that pointed patients toward amniocentesis at 35 has been retired. ACOG now recommends that both screening and diagnostic testing be discussed with and offered to every pregnant patient, regardless of age.
The chance of a chromosomal condition such as Down syndrome does rise steadily with age, so the conversation carries more weight after 35. But the tests themselves are the same ones offered to a 27-year-old: cell-free DNA screening from a blood draw, first trimester ultrasound and blood work, and diagnostic options like chorionic villus sampling or amniocentesis if you want a definitive answer. Genetic counseling beforehand helps you decide which of those you actually want, rather than defaulting into all of them.
