What makes a man irresistible? Is it that bashful look he gives only to you? Or how he always knows how to make you laugh? Maybe it’s the way his no-way-they’re-real washboard abs glisten in the sun?
No, no, and well… no, probably not.
Is it his stink after a particularly sweaty gym sesh?
Science says your sexiest body part may actually be your unwashed armpits. And though the idea of your SO’s BO doesn’t necessarily reek of romance, several researchers disagree. So men, it’s time to quit showering and hide your deodorant. It turns out: love really does stink.
The aptly named sweaty T-shirt study was the first to test the role of body odor, or "major histocompatibility complex" (MHC) molecules in human mate selection. In the study, conducted in the '90s by a Swiss biologist, women smelled a variety of T-shirts worn by men for three nights in a row. The men went au naturel -- as in, no deodorant, cologne, or scented soaps the entire time.
