| ■ Male Sweat Causes Hormonal Changes in Women | 07.02.13 |
| Hey guys, you can toss out the expensive cologne. Your sweat is enough to grab a woman's attention, according to scientists at the University of California, Berkley. The found that male sweat contains a musky-smelling chemical called androstadienone that can lighten a woman's mood and heighten her sexual arousal. It can also speed up a woman's heart rate, increase her blood pressure, and raise levels of the stress hormone cortisol, the Daily Mail (U.K.) reported. This is the first evidence that humans -- like moths and butterflies -- give off a scent that has a physical effect on members of the opposite sex. The study appears in the Journal of Neuroscience. "Many people argue that human pheromones don't exist, because humans don't exhibit stereotyped behavior. Nonetheless, this male chemical signal .. does cause hormonal as well as physiological and psychological changes in women," study leader Claire Wyart, a post-doctoral fellow, said in a prepared statement. |
