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.
Even with all the understandable talk of “windows of opportunity” and “biological clocks,” there are ways for women over 35 to make motherhood a reality. Infertility treatments can be difficult and expensive, but fertility specialists can talk with you about options. Age is less of a limitation than it used to be.
Forty-something pregnancies are no longer considered extremely unusual. In 2016, for the first time, women giving birth in their 30s outnumbered women who gave birth in their 20s. And birth rates have gone up the fastest for women over 40, rising 19 percent since 2007.
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.
Rest assured, most healthy women who get pregnant after age 35 and even into their 40s have healthy babies. That doesn't mean you shouldn't think about smart ways to make sure you and your baby stay as healthy as possible during your pregnancy.
A woman's risk for general health issues and pregnancy-related health issues gradually increases every year — and there's not much difference between 34 and 35. However, 35 is the age at which medical research indicates that risk factors related to pregnancy merit some more discussion.

As you get closer to 40, it's biologically more difficult to get pregnant and you may have a higher risk of miscarriage, chromosomal issues, and other pregnancy complications. But most women in their 30s will get pregnant with little trouble.
But as people get older, they face an increased risk of medical issues that can potentially complicate their pregnancy. 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.
While a 92-year-old woman delivering a 60-year-old baby may sound like a bizarre plot twist from the movie “Benjamin Button,” it's true. Huang Yijun, 92, of southern China, recently delivered a child which she'd been carrying for well over half a century. The baby wasn't alive, however.
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).
This is because, between the ages of 30 and 40 years, a woman's chance of conceiving per cycle fall from approximately 20% to just 5%.
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.
If you're 17 years old or younger or 35 years old or older, your pregnancy could generally be considered "high-risk." Women tend to have a window of time when it's easier on their body to grow a baby and give birth.
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.
An adequate intake of folic acid during pregnancy, believed to protect against neural tube defects (NTDs) in babies, may also help prevent Down's syndrome, researchers report in The Lancet this week.
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.
Male Fertility Facts
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.
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).
Folic acid is a vitamin that every cell in your body needs for healthy growth and development. Taking folic acid before and during early pregnancy can help prevent birth defects in your baby's brain and spine called neural tube defects and birth defects in your baby's mouth called cleft lip and cleft palate.
The rate of Down syndrome for both maternal and paternal age greater than 40 years is approximately 60 per 10,000 births, which is a six-fold increase compared with maternal and paternal ages less than 35 years of age. In this age group, the paternal contribution to Down syndrome was 50 percent.
The chance of having a child with Down syndrome increases over time. The risk is about 1 in 1,250 for a woman who conceives at age 25. It increases to about 1 in 100 for a woman who conceives at age 40. The risks may be higher.
There is nothing you can do to prevent or avoid your child having Down syndrome. However, your risk is lower if you have children at a younger age.
