"The underarm contains physiologically active pheromones," says chemist George Preti of the Monell Chemical Senses Center in Philadelpha, Pennsylvania, who led the study. These behaviour-altering chemicals - which are common throughout the animal world - can affect the brain, and hence our bodies, without our even realizing it.
For six hours, female volunteers were exposed to pheromones concentrated from manly armpit odour - mercifully masked by fragrance. Levels of luteinizing hormone, a key player in the menstrual cycle, were monitored.
