Trent Arsenault's Fertility Smoothie Recipe

(ABC News)

Women and couples wanting to conceive have increasingly turned to the growing online world of free sperm donation. Trent Arsenault, a 36-year old computer engineer, has been donating his sperm since 2006 and says he has fathered 14 children, including a set of twins. He posts pictures of himself and his offspring on his website.

To insure that Arsenault gives his recipients the healthiest and most potent product, he has a strict physical regimen and a diet that includes organic foods and his homemade "fertility smoothie" twice a day.

"It has all kinds of ingredients," he said. "Lots of anti-oxidants, amino acids, fructose …. which I think all play a part in improving sperm count and fertility and hopefully making healthy babies." Whether it helps or not, Arsenault, who is not a medical professional, claims to have had his sperm count tested and that it is "approximately four times higher than the average man."

Here is the recipe:
