After age 30, a woman's fertility decreases every year. The number and quality of her eggs goes down until she reaches menopause. Menopause usually happens around age 45 to 55. During that time, women stop having their periods and are no longer fertile.
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.
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.
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.
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.
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.
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.
There's more to consider about pregnancy past your mid-30s. 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.
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.
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.
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.
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.
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.
Having Babies After 35 Is Safe
And while it's true that conceiving after 35 comes with an increased risk of complications—like preeclampsia, gestational diabetes, chromosomal abnormalities, and even miscarriage or stillbirth—many people go on to deliver healthy babies.
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.
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.
Your Chances of Getting Pregnant: Early 30s (30 to 34)
Your odds of conceiving are still high—up to an 86% success rate for couples that try for a full year. The only major change is that your chances of miscarriage by age 30 have risen to 20%.
You are at increased risk for a premature or low birth baby, birth defects and genetic abnormalities. For instance, the risk for Down's syndrome is one in 900 for all women. By age 35, however, the risk for Down's increases to one in 356 and by age 40, to one in 94.
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.
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.
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.
Although women older than 35 years of age make up a small portion of all births6 in the United States each year, about nearly one-half of babies with Down syndrome are born to women in this age group.
It is well known that the extra chromosome 21 originates from the mother in more than 90% of cases, the incidence increases with maternal age and there is a high recurrence in young women.
Best biological times to have a baby
Typically, the 20s mark a time of high fertility for both males and females. According to the American Society for Reproductive Medicine, females experience a slight reduction in fertility in their early 30s, and this will decrease significantly between the ages of 35 and 45.
