The website of the world record authority Guinness World Records lists the oldest father ever as Australian Les Colley (1898-1998), who allegedly fathered his ninth child at age 92 with a Fijian woman he met through a dating agency.
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 ...
Danish astronomer Peder Horrebow and his wife Anne Margrethe Rossing had a total of 20 children. One of their sons, Christian Horrebow, born 1718, continued his father's astronomical studies.
The oldest recorded mother to date to conceive was 73 years, while the youngest mother was 5 years old. 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).
The British monarch with the most legitimate children was Edward I, who had 19 children with Eleanor of Castile and Margaret of France of whom 8 reached adulthood.
The most fertile woman in history is alleged to be an 18th-century Russian peasant called Valentina Vassilyev. Between 1725 and 1765, she is recorded as giving birth to a total of 69 children – 67 of whom survived infancy. This included 16 pairs of twins, seven sets of triplets, and four sets of quadruplets.
Sultan Moulay Ismaïl of Morocco, "The Bloodthirsty," reputedly sired hundreds of children and perhaps more than a 1,000. Now computer simulations suggest this could have been possible if the ruler had sex about once a day for 32 years.
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 website of the world record authority Guinness World Records lists the oldest father ever as Australian Les Colley (1898-1998), who allegedly fathered his ninth child at age 92 with a Fijian woman he met through a dating agency.
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 happens faster once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely.
The man named Jonathan, aged 41, could be fined more than €100,000 (£88,000) if he tries to donate again. He was banned from donating to fertility clinics in the Netherlands in 2017 after it emerged he had fathered more than 100 children.
One study estimated a woman can have around 15 pregnancies in a lifetime. And depending on how many babies she births for each pregnancy, she'd probably have around 15-30 children.
Known as the Sperminator the inseminator, or perhaps even "America's Dad," Ari Nagel is the biological father to over 100 children across the world.
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.
This unidentified boy is the youngest father in recorded history at 9-years-old. The mother was eight years old when giving birth to their child. That makes them the youngest biological parents in history and the youngest in terms of combined age.
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.
Another study that evaluated the relationship between age and semen parameters also concluded that male fertility decline begins at 35, and suggested that male fertility peaks between 30 and 35. Bottom line: Men generally see a decrease in fertility beginning at 35, and the decline progresses from there.
At what age do men stop producing sperm? 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.
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.
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.
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.
Edward VI became king at the age of nine upon the death of his father, Henry VIII, and a Regency was created. Although he was intellectually precocious (fluent in Greek and Latin, he kept a full journal of his reign), he was not, however, physically robust.
The youngest ever monarch, Mary, Queen of Scots, became queen in 1542 when she was just six days old. She was less than a week old at the time that her father, James V of Scotland, died.
King Sobhuza II, of Swaziland, reigned longer than any monarch in recorded history. He ruled from when was one year old, all the way through the end of his life, at 83.
