Advanced maternal age describes a pregnancy where the birthing person is older than 35. Pregnant people over age 35 are more at risk for complications like miscarriage, congenital disorders and high blood pressure.
Definition of geriatric pregnancy
We define advanced maternal age (formerly geriatric pregnancy) as those who are 35 years or older at their estimated delivery date.
After age 35, there's a higher risk of pregnancy-related complications that might lead to a C-section delivery. The risk of chromosomal conditions is higher. Babies born to older mothers have a higher risk of certain chromosomal conditions, such as Down syndrome. The risk of pregnancy loss is higher.
A “geriatric pregnancy” is an outdated, but still commonly used, term to describe pregnancy in individuals 35 years of age and older. The term “advanced maternal age” is the more recent term to describe pregnant individuals who are over the age of 35.
Geriatric pregnancy is a rarely used term for having a baby when you're 35 or older. Rest assured, most healthy women who get pregnant after age 35 and even into their 40s have healthy babies.
Advanced maternal age (AMA) is the term doctors and midwives use to describe a woman who'll be 35 years of age or older when she gives birth to her baby.
While delivering at age 35 and older is officially considered “advanced maternal age,” Dr. Kalish notes that in reality, there's no “magic number” for being at-risk for complications. “A healthy 38-year-old could have an easier pregnancy than a 20-year-old who has multiple medical issues,” Dr.
Pregnancy in Your 40s
If you get pregnant after 35 years old, experts call this an “advanced maternal age” pregnancy. But it's still possible to get pregnant and deliver a healthy baby in your 40s. Childbirth at older ages has become more common too. Since the 1990s, birth rates in people aged 40-44 have gone up.
At age 35, you are considered to be of advanced maternal age. Your doctor uses this age as a guide to understand certain risk factors you may have that a younger woman may not. These include risks of health problems, pregnancy complications, and birth defects.
You may have heard that a woman's risk for complications during pregnancy goes up after age 35. The fact is that most women in their 30s and 40s have healthy pregnancies and healthy babies. To ensure a healthy pregnancy, you should do what any woman should do: Prepare for your baby with healthy lifestyle choices.
By age 43, your egg supply is near its end. Your risk of pregnancy complications, such as high blood pressure and gestational diabetes, increases after 35 as well, and continues to rise into your 40s. Miscarriage rates begin to skyrocket in your 40s as well.
Down syndrome occurs in people of all races and economic levels. The risk increases with the mother's age (1 in 1250 for a 25 year old mother to 1 in 1000 at age 31, 1 in 400 at age 35, and about 1 in 100 at age 40). However, 80% of babies with Down syndrome are born to women under age 35 years.
“So, every patient is different and every case is unique. However, from the current medical evidence, most medical authorities do state that if multiple C-sections are planned, the expert recommendation is to adhere to the maximum number of three.”
Male fertility generally starts to reduce around age 40 to 45 years when sperm quality decreases. Increasing male age reduces the overall chances of pregnancy and increases time to pregnancy (the number of menstrual cycles it takes to become pregnant) and the risk of miscarriage and fetal death.
There's no expiration date on when guys can father a child. Case in point: Rocker Mick Jagger just had his eighth child at the age of 73. Since men don't hit menopause—the time in a woman's life where her fertility ends—they can typically continue to father children into their later years.
Superfetation is a phenomenon that occurs when a pregnant woman releases an egg, usually a few weeks into her pregnancy, and it's fertilized and implants in the uterus. The result is two separate pregnancies happening at the same time.
6.9 percent in women age 35 to 37. 6.8 percent in women age 38 to 40. 5.1 percent in women age 41 to 42. 5.9 percent in women age 43 and above.
The study found that pregnancy rates decreased progressively with increasing age of the recipient female patient 6. The cumulative pregnancy rate observed up to 12 insemination cycles was 74% for women younger than 31 years and decreased to 62% for women aged 31–35 years and to 54% for women older than 35 years 6.
Premature birth and low birthweight baby
Plenty of reports exist around older mothers having a higher risk of premature birth or low or high birthweight babies (Jolly et al, 2000; Luke and Brown, 2017). For example, one study found that mums aged 40 or over had a higher risk of preterm birth (Fuchs et al, 2018).
Although it doesn't happen in every case, there is evidence that subsequent babies get bigger. Babies also tend to be bigger as women get older. Some studies suggest that if you're expecting a boy, his birth weight will depend on the sex of your previous child.
The study confirmed that women over 40 do have the highest risk of preterm births: 7.8 percent of pregnancies in this age group resulted in preterm births and 1 percent ended in extremely premature deliveries.
