Millions of years ago, humans could detect pheromones. We could “smell” each others’ genetic material through particular detectors that have since gone dormant now that we can see in color. It seems that this organ, called the vomeronasal organ, is no longer connected to the brain (does this mean those fragrances with pheromones are pointless?). However, some scientists say that we can pick up on pheromones through our normal sense of smell. But if scientists could find a way to reconnect the VNO, as it’s known, to the brain, you might have what you call a “sex sense” that would allow men to smell when women are ovulating and decide whether or not it’s the right time to have sex. In short, it would change your sex life, and could even be the most effective birth control method ever. [Mental Floss]
