A failed anti-depression drug may end the elusive search for the female version of Viagra.

During its initial clinical testing, flibanserin didn't cheer women up; rather, many who took it reported "an increased libido that they liked." This led to a series of studies in which pre-menopausal women in three countries went on a 24-week course of the drug and documented in a diary the intensity of their sexual desires and how many satisfactory sexual encounters they had.

Researchers found 100 milligrams a day of the drug resulted in "significant improvements" on both fronts relative to women who took a placebo. While Viagra and other erectile dysfunction medications work on the blood supply, flibanserin achieves its action on the fairer sex by heading directly for a female's sexually complicated brain.

Not only is this potentially great news for sexually bored women (and the men who want to have sex with them), but "The Flibanserin Diaries" would make for a terrific high-concept porn. Anyone have a contact at Cinemax?
