More proof that men are evil.

Our boyfriend laughs - in a vaguely uncomfortable sort of way - whenever we snuggle up to his chest and inhale deeply near his underarms. But what can we say? Male sweat: it's what's for dinner.

Now researchers at UC Berkeley are announcing what most of us women-folk have known all along. According to CNN.com:

"Researchers at the University of California at Berkeley said women who sniffed a chemical found in male sweat experienced elevated levels of an important hormone, along with higher sexual arousal, faster heart rate and other effects."

Unfortunately, the study also reports that the scent of sweat elevates levels of cortisol, and elevated cortisol, if late-night infomercials are to be believed, causes weight gain.

"The researchers measured levels of the hormone cortisol in the saliva of 48 female undergraduates at Berkeley, average age of about 21, after the women took 20 sniffs from a jar of androstadienone. Cortisol is secreted by the body to help maintain proper arousal and sense of well-being, respond to stress and other functions. Cortisol levels in the women who smelled androstadienone shot up within roughly 15 minutes and stayed elevated for up to an hour."

Lest you think you can just keep your nose away from his upper body and avoid turning into a fat-ass, the report goes onto say that androstdienone, a derivative of testosterone

"...is found in male sweat as well as in saliva and semen. It smells somewhat musky."

Guess making out and blow jobs are out of the question too. As they say, a minute on the lips, forever on the hips.
