Researchers find chemosignal that encourage women's sexual desire
If only they could bottle it up.

Breastfeeding women and their infants produce a substance that increases sexual desire among other women, according to research at the University of Chicago.

"This is the first report in humans of a natural social chemosignal that increases sexual motivation," said Martha McClintock, the David Lee Shillinglaw Distinguished Service Professor in Psychology at the University, and the lead researcher in a team at the University's Institute for Mind and Biology. Chemosignals are substances that while not necessarily perceived as odors, nonetheless have an impact on mood and menstrual cycles when absorbed through the nose.
