Ed Houben of the Netherlands has gained a reputation as Europe's most passionate sperm donor for fathering 46 children without having sex. Houben donated at an IVF clinic at first, but had to stop once he reached his quota of 25 gifts. Now people find him on the internet and through word of mouth. Houben has traveled to hotels across Europe, where he hands over fresh samples to women and leaves while they perform self-insemination. He has met some of his children, but will not have a parent relationship with them. "I do it because I know how hard it is for people who desperately want a child," he says. [The Telegraph]
