While certain risks may rise with age, men continue to produce sperm throughout their lives and can father healthy children into old age.
In short, yes (Harris 2019, NICE 2013). Although most men are able to have children well into their 50s and beyond, it becomes gradually more difficult after the age of 40 .
Go for it! Don't stress about your age. Focus on the positives, throw yourself in and give it everything you've got. Take care of your health and use your secret weapon of 'maturity' to be the best dad you can.
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.
Gone are the days when it was considered unheard of for parents to have children after the age of 35. With proper support and medical care, parents of any age have every reason to believe that they can have healthy babies.
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.
Each woman is born with a set number of eggs. You release an egg each time you ovulate, about 14 days before you have your period. So as you get older, you have fewer and fewer eggs, and the eggs you have aren't easily fertilized by a man's sperm. All this makes it harder for you to get pregnant.
Pregnancy in Your 40s
If you get pregnant after 35 years old, experts call this an “advanced maternal age” pregnancy. But it's still possible to get pregnant and deliver a healthy baby in your 40s. Childbirth at older ages has become more common too. Since the 1990s, birth rates in people aged 40-44 have gone up.
Turns out, men have their own ages to be mindful of. “It's on a hockey stick shaped curve [of risks], just as it is with women, but with men the stick is a lot longer. The risks can start at 40 or maybe even 50 or 60 and then [risks] rapidly rise after 60,” says Dr. Paul Turek, a men's health and fertility urologist.
Researchers at Stanford University, for example, found older father were linked to increased risks of low birth weight and seizures in newborns. Advanced paternal age is also associated with increased rates of various childhood cancers, as well as congenital cardiac defects.
Older paternal age may be harmful to the offspring's health in terms of genetic mutations, telomere length, and epigenetics [66]. Several lines of evidence suggest that epigenetic changes occur in the sperm of older fathers, particularly defects in DNA methylation [67–69].
If you need a little reassurance that it's not too late, consider this: Twice as many dads of newborns are now in the 40-plus age group, compared to the 1970s. Of the roughly 4 million births each year in the U.S., about 9 percent of fathers are over 40.
The age where a man is most fertile is between 22 and 25 years. It is suggested to have children before the age of 35. After this age, the male fertility begins to worsen. After 35, the sperm might result in pregnancies where mutations can occur.
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.
Having a baby after 40 may give couples the chance to wait until they are more emotionally and financially prepared for parenthood. However, it can make it more difficult to get pregnant, as fertility declines with age.
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).
By their mid-40s, customarily considered the likely end of childbearing years (though of course there are exceptions), about 1 in 7 (or 14 percent) never did have any kids.
Geriatric pregnancy is a rarely used term for having a baby when you're 35 or older. Rest assured, most healthy women who get pregnant after age 35 and even into their 40s have healthy babies.
Older women are more likely to have a baby with a chromosome disorder such as Down syndrome. If you are age 25, the chance of Down syndrome is about 1 in 1,250. If you are age 35, the risk increases to 1 in 400.
If you're under 35 and in good health, it's perfectly natural for it to take up to a year. It can take longer if you are older, however; for women aged 38, 67% who have regular unprotected sexual intercourse will only get pregnant after two years of trying2.
Miscarriage rates by age
Under 35 years old: There is a 15% chance of pregnancy loss. Between 35 and 45 years old: There is a 20–35% chance of pregnancy loss. Over 45 years old: There is a roughly 50% chance of pregnancy loss.
Eat a balanced, nutritious diet, lose weight if you are overweight, and take a prenatal vitamin that has at least 400 micrograms of folic acid. You should have a full medical exam before you become pregnant. Tell your doctor that you are planning to become pregnant and ask about potential health risks.
