MORE SEX
Do humans have a sex organ up their nose? Scientists believe that a tiny nasal structure called the vomeronasal organ, or VNO, may be a primitive sensory organ used for detecting pheromones, a chemical that animals release to signal readiness for mating. The VNO consists of a pair of tiny indentations on either side of the nasal septum. In other animals such as rats and mice, the VNO allows animals to detect who’s ovulating and who’s ready to mate. Does this organ function similarly in humans? It has been known for decades that women roommates in college dorms begin to menstruate in unison after several months of living in the same quarters. One explanation is that women are sensitive to each others’ pheromones. Perhaps, like all other beasts in the animal kingdom, we can sniff out when someone’s ready for mating. So here’s some advice to guys on the prowl: better pop those decongestants before hitting the pickup bars.
I’m sorry, but of all of your weird biological facts, this one grossed me out the most… Even more than the story of the girl with the bezoar in her stomach… And that last line was the clincher! Blech!
