Although most men are able to have children well into their 50s and beyond, it becomes gradually more difficult after the age of 40 . There are many reasons for this, including: Sperm quality tends to decrease with age.
There's no maximum age that stops a man from being able to have a baby. You can become a father long into your older years, but there are risks.
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.
Am I too old? While certain risks may rise with age, men continue to produce sperm throughout their lives and can father healthy children into old age.
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.

And “advanced paternal age” is not as old as you may think. Men older than 35 are considered to be of advanced paternal age. So a man who is just 36 may have a higher risk pregnancy with his partner compared to a man who is 30.
While the majority of children are born to fathers between the ages of 20 and 34, becoming a later-in-life dad is a distinct trend. Current research indicates that since 1980, birth rates have increased 40 percent for men ages 35 to 49.
Even with all the understandable talk of “windows of opportunity” and “biological clocks,” there are ways for women over 35 to make motherhood a reality. Infertility treatments can be difficult and expensive, but fertility specialists can talk with you about options. Age is less of a limitation than it used to be.
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.
A trained expert checks your sperm count, their shape, movement, and other characteristics. In general, if you have a higher number of normal-shaped sperm, it means you have higher fertility. But there are plenty of exceptions to this. A lot of guys with low sperm counts or abnormal semen are still fertile.
Men's age and fertility
Male fertility generally starts to reduce around age 40 to 45 years when sperm quality decreases. Increasing male age reduces the overall chances of pregnancy and increases time to pregnancy (the number of menstrual cycles it takes to become pregnant) and the risk of miscarriage and fetal death.
Pregnancy rates decrease with paternal age. Men will generally see a 52% decrease in fertility rate between their early 30s and their mid-to-late 30s. Time to conception. Compared to men 25 years or younger, men 45 years or older are 12.5 times more likely to take over two years to conceive.
While it's true men continue to produce sperm into old age, it doesn't mean they'll be fertile at 50. And just as a woman's chances of getting pregnant start to decline in her mid-30s, so does a man's fertility. So if you're a guy in the 40 and over club and you're thinking of more offspring, pay attention.
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.
Australian dads are among the oldest in the world, and we're not getting any younger. According to the Australian Bureau of Statistics' data on registered births in 2020, the median age of fathers is 33.6 years, rising from 28.5 years in 1975, when data was first collated.
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.
Men can produce sperm from puberty to a ripe old age and continue to father children as long as they do so. Women, on the other hand, have a limited fertile window. Past 51 – the average age of menopause – they cease to release any eggs and become infertile. Both men and women are delaying having children.
Unlike women, who are born with a finite number of eggs, men continue to produce sperm throughout their life, and some can father children into their 60s and beyond — an age where women's clocks have totally stopped ticking.
Back in 2017, Eisenberg published a study showing that the number of older men fathering children was on the rise. Now, about 10 percent of infants are born to fathers over the age of 40, whereas four decades ago it was only 4 percent.
The scientists also note that at the age of 35, the proportion of sperm carrying an X chromosome also seems to increase, meaning older dads are more likely to have daughters. In human reproduction, the Y chromosome is responsible for making a male child.
The American Psychological Association defines "middle adulthood" as beginning at 35 or 36, and many ranges do not end until 60 or 65. The Lancet considers midlife as starting from around age 40. Modern social scientists generally agree that midlife begins around 35 to 40 and ends around 55 to 60.
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.
Furthermore, fathers were consistently older, at 30.7 years on average, than mothers, at 23.2 years on average, but the age gap has shrunk in the past 5,000 years, with the study's most recent estimates of maternal age averaging 26.4 years.
