A 36-year-old man is believed to have fathered 14 children despite never having had sex.

Trent Arsenault of San Francisco found himself in the unique position after launching a website in 2006 offering free sperm donations to childless couples.

Speaking to Anderson Cooper on his US chatshow, the self-professed "tech-geek" explained: "I coined this term 'donor sexual' and I'll explain it means 100% of my sexual energy is for producing sperm for childless couples to have babies. So I don't have other activity outside of that.

"I will probably be the 40-year-old virgin. Except I'll have 15 plus kids."

The appearance also saw Arsenault come face-to-face with one of his children, a 23-month-old daughter named Analise, for the first time.

"I'm trying to not get too emotional," he said. "I'm just extremely happy that she's healthy and in a loving home. I hope she has the gene of compassion and that her parents nurture that."

Arsenault was threatened with a one-year jail sentence and a fine of $100,000 last December after the FDA accused him of failing to prevent the spread of disease and found him to be unlawfully manufacturing human cells.
