what to do if your 44 and pregnant
The Truth About Pregnancy Over 40
More than than 100,000 Americans give nascence in their 40s each year, but what does that mean for the health of their pregnancies and their babies?
This story was originally published on November. 12, 2019 in NYT Parenting.
At some point in uncomplicated school, I understood something about my mother: She was older than the other moms. Every now and then, I would write her age on a form or talk about the year she was born, and a classmate would loudly exhale at the response. "Human," she would say, "that's ANCIENT."
Indeed. My mother was a whopping 29 when she got pregnant, and 30 when she gave birth to me.
This situation came to mind earlier this year, when my father-in-police force expressed unprompted business about the possibility of my husband and me having a 2d child at my "advanced historic period" of twoscore. We were courtship medical disaster, he said, for myself and for the infant.
My first response was fury — O.Thousand., boomer — just did he take a point? In 2019, the Centers for Disease Control and Prevention announced that while the birthrates for women nether 40 had been declining for years, those for women in their early on 40s were increasing — past 3 percent every year since 1982. The average age of first-time mothers in the The states is now 26 — up from 23 in 1994. And in Manhattan, nearly where I live, it'southward 32.
Risk is a squishy concept, and it is tricky to square scientific research with ane's personal experience, only in that location are undoubtably certain hazards specific to what, until recently, was chosen a "geriatric pregnancy." To put those issues into perspective, I spoke with six experts to learn near the unique concerns that may arise with having a kid later on forty.

It'south harder to get pregnant
This is probably the best-known part of the aging equation. The fact is, eggs gradually refuse in number and quality equally you get older. If y'all're over 35, yous're considered to be of "avant-garde maternal age" — with fertility starting to drop nearly significantly around 32, co-ordinate to the American Higher of Obstetricians and Gynecologists, and taking a particularly deep nose swoop around 37. "Past age 44, the chances of spontaneous pregnancy approach zero," said Dr. Jane van Dis, M.D., an ob-gyn practicing in Burbank, Calif.
Of class, reproductive technologies such as in vitro fertilization tin can help some couples skirt those numbers, simply even those efforts can become less successful with age. Co-ordinate to a 2016 written report from the C.D.C., one in vitro fertilization wheel has a 36 percent chance of successfully impregnating a adult female under 35, whereas it has about a 22 percent run a risk for women between 38 and 40, almost a thirteen percent gamble for those 41 or 42, and virtually a half-dozen per centum chance for women over 42.

Information technology's harder to stay pregnant
Miscarriages and stillbirths can happen at any historic period, simply the chances increase every bit y'all become older. Pregnancy losses that happen before xx weeks — which are called miscarriages; anything subsequently is considered a stillbirth — are about always caused by chromosomal problems in the embryo, which are more likely in older eggs. For this reason, according to Dr. van Dis, women between twoscore and 44 have a 33 percentage chance of miscarriage. Across all pregnancies, miscarriage adventure is believed to be closer to 10 to 20 per centum, though estimates can vary. It is possible these percentages may be higher, because, for instance, many women who miscarry exercise so earlier they know they are significant and may not report it.
Evidence also suggests that pregnant people in their 40s are at college run a risk of stillbirth. The reasons are a chip murky — though in a 2008 review of studies, researchers suggested that the college incidence of conditions similar loftier blood pressure during pregnancy or gestational diabetes among older mothers may be at least partly to blame.
Considering longer gestational times tin can increase the hazard of stillbirth, many doctors won't let a woman over 40 to go into labor past her due appointment. Generally, she will be given a planned consecration.
Your hazard for other complications increases
As you lot age, your chances of developing certain cardiovascular issues like high blood pressure and middle disease increase. This is i of the reasons women over 40 are at college risk for pre-eclampsia (high claret pressure and protein in the urine during pregnancy, which can be life-threatening) and gestational diabetes (abnormally high claret carbohydrate during pregnancy). These conditions can create a host of problems for both mother and infant — including low (or abnormally high) birth weights and premature deliveries.
Some other big problem is an increased chance of developing placenta previa, a status in which the placenta either partly or fully covers the cervix. Across all pregnancies, one in 200 volition develop the condition, with evidence suggesting a much higher risk for women 35 or older. Placenta previa is unsafe, and can increase the risk for premature labor and stillbirth.
Your risk for breast cancer might change
This was probably the biggest surprise to me: Enquiry suggests that the older a new mother is when she has her first child, the higher her risk for breast cancer. Co-ordinate to Louise Brinton, Ph.D., who was formerly main of the Hormonal and Reproductive Epidemiology Branch at the National Cancer Institute, women who have their first child later on 40 may exist at slightly college take a chance of developing breast cancer in the decade or so post-obit childbirth than those who gave birth before they were twenty. "The simplistic view is that as you lot age, your cells are constantly changing, and a heavy dose of hormone tin can promote them into cancer," Dr. Brinton said.
How this miracle translates into accented, rather than relative, risk, however, is a fleck thorny. A big written report published in 2018, for case, found that among women who had children between 34 and 47, 2.two percent developed breast cancer within three to 7 years later they gave birth (amongst women who never had children, the rate was ane.9 percent). Over all, according to the American Cancer Order, women between 40 and 49 have a 1.5 percent chance of developing breast cancer.
To misfile things further, studies have likewise shown that a history of childbirth may have a protective result confronting breast cancer afterwards in life, said Hazel Nichols, Ph.D., an associate professor of epidemiology at the University of North Carolina Gillings School of Global Public Health and one of the authors of the 2018 study. So the slightly increased take a chance of breast cancer following a birth later in life may be counterbalanced past having more children in general.
The best thing you lot can do, Dr. Brinton said, is to make sure that your doctor is aware of this risk and that you lot are regularly screened with mammograms.
Your kid may exist at take chances for certain anomalies
Once again, the older an egg, the more likely it is to have chromosomal issues, which can increment your child's risk for certain birth defects. For women who become meaning at 25, the hazard for Down syndrome, the most common chromosomal condition, is well-nigh one in ane,250; at age 40, that risk jumps to virtually i in 100.
Of class, noninvasive blood tests for chromosomal issues similar Downward syndrome allow you lot to become information nearly your child'southward genetic makeup as early equally ten weeks.
There is as well some, if limited, evidence that older fathers may pose sure risks to their offspring. A review published in 2019, for instance, found that babies born to fathers 45 or older were at higher risk for certain complications like low nascency weight, a depression Apgar score (a quick test to gauge a infant'southward well-being 1 to five minutes afterward birth) and premature birth. They besides seemed to be more likely to develop autism, schizophrenia and obsessive-compulsive disorder than the children of men who were younger. Information technology is of import to notation, still, that all such studies were observational, and so more than enquiry is needed.
The bottom line
What, and then, to brand of all of this? The nigh optimistic clinician I spoke to was Dr. James Grifo, M.D., Ph.D., program managing director at the NYU Langone Fertility Center. He pointed out that while "pregnancy is one of the riskiest states that virtually women experience in their lives," the odds of a calamitous event are still low. "The average age of my patient is 39, and obstetrically, they practice quite well," he said. "Age is non a reason non to endeavour if you want a babe."
Over and over, I found myself having two conversations with experts: One nigh what they knew from their patients or their research, and some other about the choices they made nigh when to have children on their own.
Dr. Brinton, for case, who had a girl when she was 42, said that her biggest issues were "societal" rather than medical. "I was ever the older mother," she said. "When I would go to school, I would exist asked if I was her grandmother. When it comes from a child, it's a stab in the eye."
Dr. van Dis, who had twins at 39, said she wished she had children when she was younger, but non considering of the health risks. She put off having children earlier considering of her medical career and her then-husband's ambiguity toward starting a family unit — and now she is divorced. "I would accept told my younger self that it's better to be a unmarried mom than to partner with someone who is not committed to you, just because you think you lot won't be able to have a family if you don't have a partner," she said.
Is it responsible or smart to try to accept kids at 40? Psychological studies tell u.s.a. that humans have trouble imagining themselves equally subject area to bad outcomes, which may exist why we persist in rolling the die. Joan Didion tells united states that "anything worth having has its toll." What my father-in-law didn't know is that when he sent that note, I was already pregnant.
