The smell from breasts of breastfeeding mommies can put other women in the mood for sex and spark wild fantasies, according to a new U.S. study.
This finding came from research about therapies for women with low libido, and involved asking new mothers to insert special pads into their bras.
Those pads were then sniffed by half of the study group, and the findings showed that women who were exposed to the breastfeeding smell experienced a 24 percent increase in sexual desire and 17 percent increase in sexual fantasies.
The control group, which sniffed pads that had a fake scent, reported an insignificant decrease in sexual desire and a 28% decrease in sexual fantasies.
The Chemical Senses Centre in Philadelphia conducted the study and recruited 26 breast-feeding women, who were asked to wear special pads in their nursing bras to collect samples of their sweat. The pads were then cut into pieces and frozen.
Another group of 90 childless women between the ages of 18 and 35 was assembled to test the pads, and divided into two groups. One set of women was given the breast-scented pads to sniff in the morning and before going to bed, while the other was given pads impregnated with a chemical that mimics the smell of sweat and breast milk.
Professor Martha McClintock, a psychologist at the University of Chicago, said: "We knew there are other species in which the females use social signals from other females to help identify the time when they become pregnant and have offspring at optimal times.
The effect may have evolved because the presence of other women who have just given birth could be a signal of favorable conditions for breeding, scientists suggested.
The study adds to the growing body of evidence that chemicals called pheromones trigger sexual desire and an urge to reproduce in women.
BrandweekNRX predicts that someone is bound to make a lot money off this latest scientific finding: Women's sex drive will soon be boosted by drugs based on chemicals found in the sweat of breast-feeding mothers.
