Olfactory system detects pheromones that control reproduction

behavior.

Dulac said that extending the conclusions from their studies in mice to humans is "totally speculative, but extremely interesting. There have been many observations of behavior in humans that suggest we react to pheromones," she said. "For example, it is known that women who live in close quarters tend to have synchronized menstrual cycles. But it was also believed that humans would need a functional vomeronasal organ in order to sense pheromones -- and there is no evidence for such an organ in humans.

"But now that we have identified an olfactory circuit that plays a role in sexual behavior in rodents, this requires us to rethink how mammals detect pheromones. It is quite tempting to speculate that there might be such a circuit in humans," said Dulac. "We must also rethink the simplistic division of olfaction, in which the main olfactory system governs cognitively based behavior and the vomeronasal system governs hard-wired, pheromone-triggered behaviors."
