One of the reasons Houben is so popular, he said, is because many men stopped donating sperm three years ago when the United Kingdom said donors no longer could remain anonymous, The Sun reported Monday.
As a result, British women are going to other countries to find a sperm donor or having sperm samples sent to them, said Houben, noting women find out about him through the Internet and through word of mouth.
Houben, who said he's never had sex with any of his children's mothers, recently held a party at his home for his children and their families.
"The kids had the chance to play with their half-brothers and sisters, which was nice, said Houben.
