Women's Brains Recognize, Encode Smell Of Male Sexual Sweat
A new Rice University study published in the Journal of Neuroscience found that socioemotional meanings, including sexual ones, are conveyed in human sweat. Denise Chen, assistant professor of psychology at Rice, looked at how the brains of female volunteers processed and encoded the smell of sexual sweat from men. The results of the experiment indicated the brain recognizes chemosensory communication, including human sexual sweat.
Scientists have long known that animals use scent to communicate. Chen's study represents an effort to expand knowledge of how humans’ sense of smell complement their more powerful senses of sight and hearing.
The experiment directly studied natural human sexual sweat using functional magnetic resonance imaging (fMRI). Nineteen healthy female subjects inhaled olfactory stimuli from four sources, one of which was sweat gathered from sexually aroused males.
