In fact the Dutchman, 44, is known for being the most fertile man in Europe, and quite possibly, the world.
Why? Houben has fathered a whopping 98 children in the space of 12 years. That’s a lot of sexercise.
It all started in 2002 when he donated his sperm through a local fertility clinic in the Netherlands. Fast forward twelve years where he now spreads his seed in a more traditional sense, or the ‘natural’ way, by offering a free service to have sex with women and couples who want to have a baby.
“What motivates me is meeting new people who turn out to be great, normal people and there’s some beautiful hope of creating a new life which will be loved and look after,” he told the BBC.
Through his website, Houben connects with couples — lesbians and heterosexuals — who have problems with fertility, or who lack the necessary organs needed to make a baby.
“I’m not saying the traditional family is a bad form, absolutely not, I’m just saying if they want to keep existing … we might have to reconsider what a qualified family is,” he said.
But unlike other donors, Houben prefers to be a part of the process … in more ways than one.
“I have met many children from right after birth and I’ve been present at two births, it was fantastic,” Houben said.
“As [the] children grow up they’ll develop their own relationship with me, or not, but they’ll know where they come from. For now it’s mostly the initiative of the parents to visit me twice a year, for example.”
And with a strike rate of 80 per cent, Heuben’s little swimmers are hot property. A semen analysis, otherwise known as a spermiogram, reveals he’s sitting comfortably with 100 million per count. Anything under 20 million means the carrier is ‘not a good prospect’.
‘I don’t fire blanks!’ he joked.
“A married couple came over here for one week after many years of visiting clinics in the USA and the UK. They had tried everything, then they read about me, wrote me and we had a very nice contact.
“Half a year later they managed to come, stayed for 8 days, she and I slept together four times. After ten years of trying they had their first pregnancy. Last year they came a second time for their second child and it worked almost immediately.”
But how does Heuben disconnect from the emotions of fatherhood?
“I try to keep my emotions out of it as much as possible. You have to find a balance between having these feelings of being so many times a father but also that it’s no use clamouring for that because that’s not what you promised the parents.” [MATT YOUNG]
