Sorry, fellas, but a shower and a smile will go a lot farther with the ladies than your sweaty armpits. The notion of sex-attracting pheromones was first propounded 50 years ago, when a scientist noticed that male moths stayed upwind to attract female moths with their scent. This is true for moths, but no such phenomenon has ever been shown to apply to humans, says Charles Wysocki, PhD, a neuroscientist at the Monell Chemical Senses Center in the US, and the author of the study Facts, Fallacies, Fears and Frustrations with Human Pheromones. "There is no biomedical literature to support the claim that humans use attraction pheromones," he says.
What about the supplements sold on the Internet? "Buyer beware," says Wysocki. "Their claims are anecdotal. There is no scientific proof that those products actually work."
