A man who stayed a virgin until the age 34 has become a father of 82 in the space of just nine years and he has another ten children on the way.
Dutchman Ed Houben, 42, sleeps with around 15 childless women a month in a bid to make their quests to become mothers a reality.
He is understood to be the most prolific professional babymaker in the world - and what he does is all legal.
He has sown his seed around the globe but usually waits for women to come to him these days at his home in Maastricht, although he still makes exceptions if his partners are entering a particularly fertile period. Provided they pay his travelling expenses and accommodation.
His 'family' lives in cities like Berlin - three children - and in Holland, Italy, Spain, Belgium, France and even New Zealand. The eldest is now nine while the youngest is two months old.
He began donating sperm to local clinics. Then he found there was a market for procreation the natural way and he has never looked back.
Spermaspender.de. in Germany is one of the websites he uses to connect with childless women desperate to conceive.
They know Ed has a good pedigree; he gives 80 percent of the females he has sex with a child.
All his partners must submit medical records showing they are disease and drug free while he reciprocates.
Sperm banks generally charge around four to five thousand pounds for inseminations. Ed does it for free.
He gets his partners to sign documents waiving legal claims to child support; but experts say these would be invalid in the hands of a good lawyer.
