"The females were instructed not to wear perfume or deodorant. Also, they weren't allowed to be in the test if they were using chemical contraceptives. The scientists were worried that the pill might inhibit these natural chemosignals and negatively affect their sex drives.
To begin this weird study, the women first had cotton pads taped to their armpits, then they cycled on a stationary bike for three minutes at 80% intensity.
Group one, the neutral-condition group, watched part of a boring documentary about bridge building. None reported feeling titillated. Sorry, History channel.
Group two watched a 20-minute clip from an erotic movie called "9 Songs" which featured unsimulated sex between its male and female stars.
The Results
In short, all the men rated the armpit sweat of the aroused women as more attractive. As a result, the men experienced an uptick in their own "sexual motivation."
The same men didn't feel any tingling in their special parts after smelling the sweat from non-aroused women...
In other words, concupiscent women release a particular scent via their sweat that men can sense. When men register that signal, they get pretty turned on too.
Science is fun sometimes, isn't it?"
