Ed Houben was a virgin until the age of 34. Now he's the biological father of 82 children.
Der Spiegel reports that the 42-year-old Dutchman performs his services for free, offering women and couples a chance to conceive a child without the expense of using a sperm bank.
But Houben is different from typical sperm donors in that he actually has sex with the women to whom he is donating.
According to his own self-collected data, Houben succeeds in producing a child 80 percent of the time.
While what he does is perfectly legal, Der Spiegel notes that if any of his clients tried to sue him for child support, he'd have no legal grounds to stop them.
Houben, who the Daily Mail describes as the "most prolific professional babymaker in the world," meets his clients through SpermaSpender.de, which, as Gawker explains, is "a German sperm donation network that encourages women and donors to connect independently and set up donation contracts on their own terms."
In 2008, the Telegraph wrote about Houben, who, at the time, simply gave his sperm sample to women, instead of having sex with them as he does now.
"I do it because I know how hard it is for people who desperately want a child," he told the Telegraph. "Also going through fertility clinics can be very time-consuming and costly for them."
The latest round of Houben stories come three months after a self-described "donorsexual" made headlines for fathering 14 kids without ever having sex.
