A woman's peak reproductive years are between the late teens and late 20s. By age 30, fertility (the ability to get pregnant) starts to decline. This decline happens faster once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely.
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.
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.
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.
After the age of 40, there's an increased risk of developing gestational diabetes and preeclampsia during pregnancy. Older maternal age has also been found to lead to a higher risk of premature births and emergency C-sections. Chromosomal genetic disorders are also more likely to develop when a person is older.
Older women are more likely to miscarry or have a stillbirth. They have a greater chance of developing gestational diabetes, preeclampsia, and of delivering a baby who is very small. Then there can be problems with labor, resulting in a higher chance of cesarean birth.
Some studies have shown a higher chance of miscarriage (early pregnancy loss) in older mothers. For all women, about half of first trimester miscarriages happen because of a chromosome problem in the baby. The risk of chromosome problems increase with the mother's age. So miscarriage is also more likely.
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 as you get older, you have fewer and fewer eggs, and the eggs you have aren't easily fertilized by a man's sperm. All this makes it harder for you to get pregnant. If you're older than 35 and have been trying for 6 months to get pregnant, tell your health care provider.
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.
Pregnancy Risks in Advanced Maternal Age
Your chance of miscarriage is increased, along with an increased risk of developing gestational diabetes, high blood pressure, and having a child that is preterm. You are also at risk for conceiving a child who has a chromosomal abnormality, such as Down's syndrome.
Women without children have also been found to have an increased risk of breast cancer, and increased mortality from uterine, ovarian and cervical cancer when compared to women with children. Moreover, the fertility declines with the advanced age at first childbearing.
The oldest recorded mother to date to conceive was 73 years, while the youngest mother was 5 years old. According to statistics from the Human Fertilisation and Embryology Authority, in the UK more than 20 babies are born to women over age 50 per year through in-vitro fertilization with the use of donor oocytes (eggs).
While it may take a bit longer to get pregnant if you're 35 or older, the average time it takes to conceive is still high. Women under 25 have a 25 percent chance of conceiving per cycle, compared to 15 percent among women between the ages of 35 to 39 (the rate drops to 5 percent by the age of 40).
If you're under 35 and in good health, it's perfectly natural for it to take up to a year. It can take longer if you are older, however; for women aged 38, 67% who have regular unprotected sexual intercourse will only get pregnant after two years of trying2.
If you are thinking about having a baby in your late thirties or early forties, you are not alone. Women ages 35-45 are increasingly becoming first-time moms. And most healthy women in this age group have healthy pregnancies, births and babies.
Women who become pregnant in their 30s and early 40s can have safe, healthy pregnancies, says Ellie Ragsdale, MD, director of fetal intervention at UH Cleveland Medical Center. But they do face a higher risk of some problems.
Peak male fertility is around 25-29 years old. Sperm quality begins to decline at 30. At 45, men begin to experience a significant decrease in semen volume. Older men can also take longer to conceive a child.
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.
Current supplementation policies designed to prevent neural tube defects may incidentally prevent Down's syndrome, provided a sufficiently high dose of folic acid is used.
The risk of chromosomal abnormality increases with maternal age. The chance of having a child affected by Down syndrome increases from about 1 in 1,250 for a woman who conceives at age 25, to about 1 in 100 for a woman who conceives at age 40.
Fertility in the Aging Female
Each month that she tries, a healthy, fertile 30-year-old woman has a 20% chance of getting pregnant. That means that for every 100 fertile 30-year-old women trying to get pregnant in 1 cycle, 20 will be successful and the other 80 will have to try again.
By age 30, fertility (the ability to get pregnant) starts to decline. This decline happens faster once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely.
One study found that for couples having regular unprotected sex: around 7 out of 10 women aged 30 will conceive within one year. around 6 out of 10 women aged 35 will conceive within one year. around 4 out of 10 women aged 40 will conceive within one year.
