A woman's orgasmic potential can be gleaned from the gait of her walk.

In a new study, female university students were questioned on their orgasm history before being videotaped from a distance as they walked in a public place. By analyzing the videotapes, researchers were 80 percent successful in identifying whether a woman could vaginally climax.

Researchers feel the greater the sum of a woman's stride length and vertebral rotation, the more likely the she is to be orgasmic. According the study's authors, "this could reflect the free, unblocked energetic flow from the legs through the pelvis to the spine."

Useful information, sure. But a study in which female college students are asked questions about their orgasms, and then secretly videotaped -- the only way this could get any more pervy is if it were funded by Joe Francis.
