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.
Since men require less time and fewer resources to have kids, the most "prolific" fathers today can have up to about 200 children. The number of children men can have depends on the health of their sperm and other factors like how many women they can reproduce with.
On average, the most fertile men may be able to father up to 15 children in their lifetime. However, this figure is only an estimate, and some men may not be able to father any children due to fertility issues or genetic factors.

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.
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 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.
What is the longest recorded human pregnancy? The longest recorded human pregnancy was 375 days, or just over 12 months. The baby was born at nearly 10 pounds and was healthy. The mother, Beulah Hunter, was a 25-year-old teacher from Los Angeles and the father was her husband.
In 1997, the McCaughey septuplets, born in Des Moines, Iowa, became the first septuplets known to survive infancy. Multiple births of as many as eight babies have been born alive, the first surviving set on record goes to the Suleman octuplets, born in 2009 in Bellflower, California.
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.
Heteropaternal superfecundation is an extremely rare phenomenon that occurs when a second ova released during the same menstrual cycle is additionally fertilized by the sperm cells of a different man in separate sexual intercourse.

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 ...
James Elgin Gill was born in Ottawa, Ontario, on May 20, 1987, around 128 days early or 21 weeks gestation. He set a record when he was born for the world's most premature baby.

A woman named Halima Cissé, from Mali, gave birth to nine babies, five girls and four boys, in Morrocco's port city of Casablanca.
This means the baby has three genetic parents: the father who supplied the sperm, the mother who supplied both womb and the egg nucleus, and an anonymous donor who supplied healthy mitochondria. Of these, the mitochondrial DNA is by far the smallest contribution.
