The researchers found that women who had live births had telomeres that were an average of 4.2 percent shorter than their counterparts with no children. This equates to around 11 years of accelerated cellular aging, said Anna Pollack, an epidemiologist at George Mason University and the lead researcher of the study.
Yvonne Butler Tobah, obstetrician and gynecologist at Mayo Clinic in Rochester, Minn., said a year postpartum usually resets body back to normal, but there are a few changes that can be permanent: Skin: A woman's face, areolas, stomach and moles often darken during pregnancy, and might stay that way.
It's safe to say growing and birthing a baby does “some things” to the body. And while many of those changes are temporary, like strange skin conditions experienced during pregnancy, some may be more permanent, like altered DNA.
Experts say the best time to get pregnant is between your late 20s and early 30s. This age range is associated with the best outcomes for both you and your baby. One study pinpointed the ideal age to give birth to a first child as 30.5.
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 becomes more rapid once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely for most women.
If you're older than 35 and hoping to get pregnant, you're in good company. Many families are delaying pregnancy well into their 30s and beyond — and delivering healthy babies. Taking special care can help give your baby the best start.
Due to advances in technology surrounding fertility, pregnancy, and delivery, it's possible to safely have a baby at age 40. However, any pregnancy after age 40 is considered high risk.
Median age for new moms rises to 30 in U.S.
A normal pregnancy typically costs between $30,000 and $50,000 without insurance, and averages $4,500 with coverage. Many costs, such as tests that moms who are at-risk or over age 35 might opt for, aren't totally covered by insurance. Plan to have at least $20,000 in the bank.
Two children. Research suggests that having two children is still most people's idea of the 'ideal' family size.
Our telomeres shorten and our epigenetic age increases
As people age and as cells divide and replicate, those telomeres shorten. Given that there is hyper cell production during pregnancy, it makes sense that those telomeres would shorten and, therefore, appear to age dramatically.
Research shows that having more children can actually protect women against multiple health woes, such as certain types of cancer and possibly even dementia. Just like with parenting, there are ups as well as downs here.
Body shape
During pregnancy, our body changes. Our hips widen, our breasts grow, and we find a little extra weight in places it wasn't before. Over time, our bodies will go back to normal, but it takes just that time.
For a start, there's a ton of evidence that babyfaces are attractive to humans, so perhaps ancestors with the supermodel look had more suitors and more children (sexual selection). This is backed up by the fact that babyfaces are especially attractive in women – and women tend to be more baby-faced than men.
Your ribs may have expanded, and your hips will often widen to make it easier for the baby to exit the birth canal. For some women wider ribs and hips will be permanent. As your baby grows during pregnancy you will gain weight . This helps to support your baby before and after birth.
This is called 'chloasma'. It is also sometimes known as 'melasma' or the 'mask of pregnancy'. Chloasma is thought to be due to stimulation of pigment-producing cells by female sex hormones so that they produce more melanin pigments (dark coloured pigments) when the skin is exposed to sun.
Generally, the biomedical evidence suggests younger is better. There is an increase in maternal and child health problems with older mothers and women's fertility declines, especially after the age of 35. The sociological evidence suggests that the older the better.
Keep in mind that each person has a different experience of pregnancy and parenthood, which can make it difficult to put an exact figure on the cost of a baby. But, generally speaking, it's estimated that the first child will cost anywhere between AUD$3,000 and AUD$13,000 in the first year alone.
an increase in the average age of first-time mothers (from 28.3 years in 2010 to 29.6 years in 2020) a decrease in smoking at any time during pregnancy (from 14.6% in 2009 to 9.2% in 2020) an increase in caesarean section births (from 29% in 2004 to 37% in 2020)
Up to 1965 the average woman in the world had more than 5 children. Since then we have seen an unprecedented change. The number has halved. Globally, the average per woman is now below 2.5 children.
Ages 31 to 35
In your early 30s, the chances you'll be able to have a baby are still high. You still have a lot of high-quality eggs to offer, but your odds will start to decline steadily at this age. Your fecundity rate decreases gradually until age 32. At 37, it drops dramatically.
You'll be around for less time in your child's life
Since you are older, it stands to reason that you'll be around for your child for less of their life than if you had them earlier in your life. So the idea here is if you aren't maximizing the amount of time you can be around, then you're being selfish.
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.
Age is one of the key factors that predict your ability to conceive. Your fertility starts to decline at age 30 and keeps on dropping steadily until you hit menopause. That said, it's not only possible to deliver a healthy baby after age 35, it's quite common.
