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. Strike rate: Mr Bouden gives 80 per cent of the females he has sex with a child. 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 per cent 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. Included in his paperwork is a semen analysis known as a 'spermiogram' that shows he is the real deal a sperm count of less than 20 million shows the potential donor is 'not a good prospect.' The prospects are increased for sperm counts of 80 to 100 million. Houben's count is 100 million. 'I don't fire blanks!' he joked. 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. 'If all the mothers decided to sue him for maintenance he would be paying them off for the rest of this life, and the next,' said one German family lawyer. He has sired 45 girls and 35 boys. Two of the the brood he doesn't know the sex of because the mothers won't tell him. 'My girlfriend says that what I do only makes me more interesting,' he told Germany's Der Spiegel magazine. 'She's coming to visit again soon.' But he hasn'rt managed to make her pregnant yet.
