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.
A woman in her early to mid-20s has a 25–30% chance of getting pregnant every month. Fertility generally starts to reduce when a woman is in her early 30s, and more so after the age of 35. By age 40, the chance of getting pregnant in any monthly cycle is around 5%.
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.
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.
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.
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.
If your menstrual cycle lasts 28 days and your period arrives like clockwork, it's likely that you'll ovulate on day 14. That's halfway through your cycle. Your fertile window begins on day 10. You're more likely to get pregnant if you have sex at least every other day between days 10 and 14 of a 28-day cycle.
How many eggs do women have in their 30s? There is no one right answer to this question, as certain factors – such as smoking or other personal factors – may mean a woman has fewer eggs than others. The average number of oocytes at the age of 30 would be around 72,000 (12% of maximum pre-birth levels).
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.
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.
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.
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.
As men age, their risk of fathering a child with Down syndrome may increase—the older the man, the more likely that the process of spermatogenesis, or sperm production will go awry, leading to sperm that contain errors like an extra chromosome.
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.
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.
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.
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.
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.
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.
