While it is technically possible for a 70-year-old man to impregnate a woman, the chances are significantly lower compared to younger men. The decline in sperm quality and quantity, along with other age-related factors, can make it more challenging to conceive.
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.
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 . There are many reasons for this, including: Sperm quality tends to decrease with age.
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.
Men's age matters too
We've all heard about men in their 80s and 90s fathering children, but this is rare. A father's age also affects the chance of a couple getting pregnant. It takes longer for partners of men older than 40 years to conceive.
While there is no definite age at which male ejaculation ceases, it has been suggested that it may happen when a man reaches his late 40s or early 50s. It is important to note, however, that this is not a universal rule and some men may continue to ejaculate at a later age.
Men typically never stop producing sperm, but there is a measurable decline in sperm quality as a man ages. The World Health Organization (WHO) has a set of benchmarks, known as semen parameters, for healthy sperm, including count, morphology (shape), and motility (movement).
Men over age 60 commonly have children. The oldest father to naturally conceive was reported to be a 96-year-old man from India. Fathering a child after age 90 is rare (even for the record books), but it shows that it's possible for older men to impregnate someone.
On the other hand, old fathers (≥ 40 years) could increase risks of cardiovascular abnormalities, facial deformities, urogenital abnormalities, and chromosome disorders in their offspring.
Research published over the last decade suggests that babies born to older men have an increased risk of arriving prematurely or developing birth defects, certain cancers or neurodevelopmental disorders, though the overall risk is still low.
He'll be joined in the late fatherhood club by his occasional co-star Robert De Niro, who last month confirmed he is fathering his seventh child at age 79. The pair certainly aren't the first old dads: several other male actors, musicians, and even US presidents have had kids late in life.
In a world where US birth rates were declining, one man decided to embark on a heroic journey to father as many children as he could. That man is called Robert De Niro and he has just had his seventh child at the grand old age of 79.
Although a man's fertility can theoretically last until death, sperm production has been found to decline from around the age of 50. Although it is still possible to conceive a child, and many men do have children in their 50s or later, it may take longer for you and your partner to become pregnant.
There is very limited data about men in extreme old age (80 yr and older). Of older men who produce spermatozoa in their ejaculates, sperm motility, a manifestation of viability and fertilizing capacity, tends to be reduced. The ability of men to impregnate their wives gradually reduces from age 25 onward.
A study of more than 40 million births in the US found babies born to men aged 45 or older were more likely to be born prematurely, have a low birth weight and need intensive care after birth than babies with younger fathers.
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.
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.
The body breaks down unused sperm, which does not build up to trigger further problems. Over time, not ejaculating can trigger psychological problems. For example, people with sexual dysfunctions that affect their ability to ejaculate may experience distress or embarrassment. It can also lead to relationship problems.
A male's body is constantly creating sperm, but sperm regeneration is not immediate. On average, it takes a male around 74 days to produce new sperm from start to finish. Although the average time is 74 days , the actual time frame for an individual to make sperm can vary.
According to Guinness World Records, the oldest father who had the documentation to prove it was Australian Les Colley, who in 1991 fathered a son with his third wife when he was 92. Here are some other notable men who had their mojos working well into their golden years.
The oldest confirmed father in the world is Les Colley from Australia, who was given the Guinness World Record for his feat. The pensioner had his ninth child, a son named Oswald, to his third wife at the age of 92 years 10 months.
The oldest recorded mother to date to conceive was 73 years. According to statistics from the Human Fertilisation and Embryology Authority, in the UK more than 20 babies are born to women over age 50 per year through in-vitro fertilization with the use of donor oocytes (eggs).
While a 92-year-old woman delivering a 60-year-old baby may sound like a bizarre plot twist from the movie “Benjamin Button,” it's true. Huang Yijun, 92, of southern China, recently delivered a child which she'd been carrying for well over half a century. The baby wasn't alive, however.
