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.
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).
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.
A pregnancy that begins after age 35 is classified as a high-risk pregnancy because the risk of complications is higher, not inevitable. Many of the problems that occur with pregnancies after age 35 are related to health conditions that occur more often as you age.
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.
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.
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.
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.
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.
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.
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.
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.
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%.
In a new study, Anqi Chen and Nilufer Gok at the Center for Retirement Research predicted that the final fertility rate for Millennials in their 30s – the rate at the end of their childbearing years – will average 1.96 children.
Women who first gave birth around puberty developed more health problems. The longer the first birth was delayed, up to the age of 34, the fewer the health problems now. After that age, they rose again. Health benefits started at the age of 22, peaking at 34.
You're considered of advanced maternal age if you will be 35 or older at the time of your due date.
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.
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.
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.
According to the American Society for Reproductive Medicine, as a woman reaches her mid to late 30s, she's less likely to become pregnant and more like to have miscarriages because the quality and quantity of her eggs are dwindling. Women at this age might feel tremendous anxiety when it comes to having children.
About 95 percent of the time, Down syndrome is caused by trisomy 21 — the person has three copies of chromosome 21, instead of the usual two copies, in all cells. This is caused by abnormal cell division during the development of the sperm cell or the egg cell.
Down syndrome, which arises from a chromosome defect, is likely to have a direct link with the increase in stress levels seen in couples during the time of conception, say Surekha Ramachandran, founder of Down Syndrome Federation of India, who has been studying about the same ever since her daughter was diagnosed with ...
Babies: Down syndrome continues to be the most common chromosomal disorder. Each year, about 6,000 babies are born with Down syndrome, which is about 1 in every 700 babies born.
