It's not the latest French perfume. It's not an after-bath body splash. It's not a fake tan. So what is this spray on substance that can give your sex life a jump start? Hormones.

Researchers have conducted a study with a hormone that's administered as a spray. The testosterone spray was given to women who hadn't reached menopause, had low natural testosterone levels, and had little interest in sex. On an intermediate dosage, the women realized a significant increase in their interest in sexual activity.

Though testosterone is considered a "male" hormone, all females have low levels of testosterone in their bodies. Even after administering the testosterone spray, 95% of the women in the study still had normal ranges of the hormone in their system.

There is one notable side effect, however. Women who used the spray developed an excess of body hair. Not exactly the turn-on their partner might need now, is it?
