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.
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.
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.
As the father grows older, the number of mutations in the father's genome increases, leading to an increase in the incidence of congenital malformations in offspring [11, 65]. Older paternal age may be harmful to the offspring's health in terms of genetic mutations, telomere length, and epigenetics [66].
A recent study of more than 40.5 million births in the United States revealed potentially harmful effects of advanced paternal age on a baby's risk of prematurity, low birth weight, low Apgar score and risk of seizures, as well as the mother's chances of developing gestational diabetes.
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.
Older fathers
Men's fertility doesn't stop as abruptly as women's. The testis can still produce the male hormone testosterone and sperm cells, enabling some men to father children in to their 90s.
There's no maximum age that stops a man from being able to have a baby.
There is no set time period when a man's sperm production stops. Women are born with all the eggs they will ever have. Men, on the other hand, are able to produce sperm cells for their entire lives. As men age, testosterone levels go down and for some, it might be hard to get an erection.
Although men never stop producing sperm throughout their lives, sperm production does begin decreasing after age 35. Motility, volume and genetic quality of sperm of older men are less likely to achieve a successful pregnancy even in younger women.
In a random international sample of 11,548 men confirmed to be biological fathers by DNA paternity testing, the oldest father was found to be 66 years old at the birth of his child; the ratio of DNA-confirmed versus DNA-rejected paternity tests around that age is in agreement with the notion of general male infertility ...
Semen quality and age
According to a study conducted in Israel, a man's sperm is in optimal conditions between the ages of 30-35. And in general, after age 55, sperm quality is found to be at the lowest quality.
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.
Maria del Carmen Bousada de Lara is the oldest verified mother; she was aged 66 years 358 days when she gave birth to twins; she was 130 days older than Adriana Iliescu, who gave birth in 2005 to a baby girl. In both cases, the children were conceived through IVF with donor eggs.
Estela Melendez said she never knew she had been pregnant
A 91-year-old woman discovered she has been carrying a foetus in her womb for more than 60 years. Estela Melendez, 91, from the small town of La Boca in Chile, was given the news by doctors after having an x-ray following a fall.
There's no specific answer to this question. Many men ejaculate when they are stimulated — even those above 70. Unlike popular belief, the link between sexual dysfunction and age isn't as strong. Individuals can maintain a strong libido and efficient sexual performance in their old age with the correct habits.
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).
At the age of 18, a man's body is also generally capable of producing and releasing sperm without any negative health effects, as long as he is in good overall health. Ejaculating daily at this age is unlikely to cause any harm, but it may lead to temporary fatigue or discomfort in the genital area.
No. Even masturbating frequently won't have any effect on your sperm count or your ability to get pregnant. In fact, masturbation has a number of physical and mental health benefits — here are just a few: Masturbation releases stress and physical tension.
Studies show that semen parameters are negatively affected by aging (Oliveira et al., 2014). Decreases in semen volume caused by impaired accessory gland function, and decreased daily sperm production, total sperm count, and sperm viability have also been linked to aging (Gunes et al., 2016).
At the cellular level, women's brains look four to five years younger than men's, Dubal said. Many biological markers indicate faster aging in almost all of the tissues in male bodies, Kerr said.
At the age of 60, men who had children had almost two years more on their remaining life expectancy than those without, at 20.2 and 18.4 years respectively.
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.
