Science - Making Sex Sexier.

The race is on to find new treatments for sexual dysfunction. Since the dawn of time, people have looked toward elixirs and potions to improve their sex lives. Why else, after all, would one consume ground tiger penis, horny goat weed and Spanish Fly?

Perhaps because nearly one in five men in the U.S. suffer from erectile dysfunction, according to a recent study in the American Journal of Medicine. Some researchers have estimated that as many as 40 percent of U.S. women have low libido or inability to reach orgasm. Most quick fixes simply don't work, and some, like Spanish Fly — a supposed aphrodisiac derived from beetles that can cause kidney damage — are harmful.
