Ed Houben is a man that hadn’t have sex until his 34 year of his life. Now, he has 82 kids.

Der Spiegel writes that today’s 42-year-old Dutchman makes his “business” for free, offering women and couples the chance to conceive without the cost of using bank sperm.

But Houben is different from the typical donor sperm, because he offers a “traditional way” – having sex with the women to which he is donating sperm. According to his personal analytics, Houben manages to make the child in 80% of cases, reports Huffington Post.
