A British man is reportedly the father to more than 800 kids and has a child every week.
Simon Watson, 41, sells his semen for roughly $70 each, BBC reports. He has sold hundreds in the past 16 years and makes a full-time income off of the practice. He estimates that he sells his sperm to a new person every week.
"I've got kids all the way from Spain to Taiwan, so many countries," he told BBC. "I'd like to get the world record ever, make sure no one's going to break it, get as many as possible."
Watson said he became a sperm donor after his first marriage broke down, adding that he wanted more children.
He also noted that the practice gave him an ego boost.
"I didn't get my first girlfriend until I was 18," he said. "I thought, 'I'm never going to get married and have kids.' A psychologist would say that's where it stemmed from, but I don't know, I've never been to one."
Watson now has two sons, aged 19 and 17, from his first marriage and a 10-year-old daughter from his second.
His children don’t mind his unusual profession, he noted.
"My kid's mates at school think it's funny,” he told The Daily Mirror. "My boys wouldn't do it themselves, but they've said they don't mind me doing it."
However, while his family is comfortable with what he does, his love life has suffered. His girlfriend of three years recently broke up with him.
“She was fed up with what I do," he said. "She actually told me she despised it."
While his second wife tolerated his profession, he thinks she also felt uncomfortable.
Watson sells his sperm through sperm banks but also online; he prefers to use Facebook.
"You can see what people are like on their profile, it's quite a safe way to do things,” he said.
He has earned at least over $60,000 selling his sperm through Facebook and other websites. However, he is discriminative when it comes to who he will sell what he calls his “magic potion” to.
"I can be a bit fussy about who I donate to, but generally anything goes -- I don't mind if people drink or smoke, but if someone was a drug addict I probably wouldn't do it,” he added.
