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.
The risks of miscarriage and stillbirth are higher in people who are older than 35. Also, multiple pregnancy is more common when you are older. As the ovaries age, they are more likely to release more than one egg each month. Some fertility treatments also increase the chance of a multiple pregnancy.
Women over 35 are more likely to develop gestational diabetes or high blood pressure during pregnancy. Also, there's a higher chance for women in this age group to have underlying health problems, such as obesity or heart disease.
Supplements containing Myo-inositol, folic acid and melatonin have been shown to help improve egg quality and ovarian function.
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.
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.
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. Kalish says.
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.
The risk of chromosomal abnormality increases with maternal age. The chance of having a child affected by Down syndrome increases from about 1 in 1,250 for a woman who conceives at age 25, to about 1 in 100 for a woman who conceives at age 40.
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. Screening tests can help detect certain congenital disorders.
Of course, as women age, the odds of conceiving also gradually lower. The ideal childbearing age is often considered to be in the late 20s and early 30s. Pregnancies later in life could come with some health risks. However, age is just one factor when it comes to giving birth to a child.
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.
The study found that pregnancy rates decreased progressively with increasing age of the recipient female patient 6. The cumulative pregnancy rate observed up to 12 insemination cycles was 74% for women younger than 31 years and decreased to 62% for women aged 31–35 years and to 54% for women older than 35 years 6.
If you're 35 years old or older and pregnant, you're considered to be of advanced maternal age, or AMA. This can put your pregnancy in the high-risk category for a number of reasons, including an increased risk of complications for you and your baby.
Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21. This extra genetic material causes the developmental changes and physical features of Down syndrome.
You can't prevent Down syndrome since it's a genetic condition. To learn more about your risk of having a child with a genetic condition, talk to your healthcare provider about genetic testing.
Down syndrome, also called trisomy 21, happens by chance, can't be prevented, and isn't caused by anything a parent did or didn't do. Fortunately, the health problems can be managed well, especially when found early, and many resources are available to help kids and their families.
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.
It is estimated that approximately 1 in every 1100 babies born in Australia will have Down syndrome. This means that approximately 290 new babies with Down syndrome are born each year. The incidence of births of children with Down syndrome increases with the age of the mother.
The only way to avoid Down syndrome at the time of conception is IVF. Pre-screening during IVF can test the embryo in the lab for Down syndrome before the embryo is transferred to the mother. Down syndrome screening is offered to everyone during pregnancy.
Birth Defects (78%)
Reality Check: About 97 of every 100 babies born in the U.S. arrive without a major birth defect, such as spina bifida or Down syndrome.
