New studies suggest that women can tell when a man is sexually aroused from his sweat, but apparently no one wants to know, as "clinical strength" antiperspirants have proven a huge hit for deodorant makers.
As mentioned last week, a new study published in The Journal of Neuroscience has shown that women can detect the differences between men's "neutral" sweat and sweat when they are sexually aroused. Researchers had 20 heterosexual men hold absorbent pads under their arms while watching erotic films and films with neutral content, then had 19 heterosexual women smell the pads of the men who were most aroused, explains today's The New York Times. All but two of the women said they couldn't smell any human odor on the pads and none said they could tell the sexual sweat from the neutral sweat. However, scientists found that the sexual scents caused activity in different areas of the women's brains than the neutral scents; brain activity didn't indicate that they were turned on by the smell of sexual sweat, but the brain could recognize the emotional information contained in the sweat, meaning that humans are communicating through smell.
