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.
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.
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.
Those women who have late menopause and they have babies early and often have babies without difficulty, well into their early to mid 40s, but it's rare for any population you study that women have successful pregnancies after 45 with any kind of frequency.
If you're older than 35 and hoping to get pregnant, you're in good company. Many families are delaying pregnancy well into their 30s and beyond — and delivering healthy babies. Taking special care can help give your baby the best start.
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.
In the United States, birth rates for women in their 30s are at the highest levels in three decades. However, an older mother may be at increased risk for miscarriage, birth defects, and pregnancy complications such as twins, high blood pressure, gestational diabetes, and difficult labors.
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.
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.
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.
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).
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.
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.
At age 30, fertility slowly starts to decrease. Most women don't have trouble early in the decade. In fact, even as you inch closer to your late 30s, your chance of getting pregnant within a year is around 65 percent. Age 37 is when fertility decreases more rapidly.
1 Yes, your odds of conception at 33 are not as good as they were at 28. At around age 37, fertility starts to decline at a much more rapid pace. Research has found that in any given month your chances of getting pregnant at age 30 are about 20%. Compare that to your odds at age 40, which are just 5%.
Falling fertility: A woman's ability to get pregnant begins to decrease slightly at age 27, and then decreases significantly after the age of 37. The average healthy couple under the age of 30 has about 95% of conceiving within a year. Once you're over 30, the chance of getting pregnant decreases by about 3% each year.
Most mums in their 30s have healthy pregnancies but the older you are, the more likely you are to have ongoing health conditions, such as diabetes and high blood pressure . These conditions can affect how well your pregnancy and birth goes . Sadly, miscarriage is more common in older women (Fretts 2018, RCOG 2011).
Your Chances of Getting Pregnant: Mid-Late 20s (25 to 29)
From age 25 to 34, you have an 86% chance of conceiving after trying for a year. Your chances of miscarrying are 10%, only a little higher than they were in your early 20s. Keep doing what you've been doing and you'll be likely to have a baby within a year.
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.
For example, a woman at 30 often has around 100,000-150,000 eggs in reserve. By 35, that number is likely around 80,000. Late into the thirties, that number could be 25,000, 10,000, or fewer.
