A new study has found that women's sexual desire is heightened if they are near breast-feeding mothers.
Researchers say these women are turned on by a chemical odour from the mothers, and possibly their infants.
Scientists think the substance could be a pheromone that evolved to stimulate reproduction at the right time.
The pheromone would have helped encourage other women to reproduce when circumstances were good.
Pheromones are chemical signals picked up by the nose, but not detected as smells, which affect behaviour.
The study, led by Professor Martha McClintock, from the Institute for Mind and Biology at Chicago University, found that women with partners experience a 24 per cent increase in sexual desire after two months of exposure to sweat, milk and infant saliva samples collected from breast-feeding mothers.
Women without partners experience a 17 per cent increase in sexual fantasies over the same period.
