Turn-on in male sweat is identified

For women, apparently there’s nothing like the smell of a man’s sweat.

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

The study -- published this week in the Journal of Neuroscience -- is the first direct evidence that people secrete a scent that influences the hormones of the opposite sex, the researchers said. The chemical smells somewhat musky.
