Menstrual synchrony (sometimes called the McClintock effect) is a putative phenomenon in which menstrual cycles of women living in close proximity become synchronized 345 ; this has been cited as physiologic evidence of pheromone functionality in humans. For the sake of convenience, we will label the rat that secretes pheromones as Rat A. Pheromones and Behavior in Humans Pheromones can be found on the skin of humans, most prominently around the eyes, anus or the chin - areas that are typically associated with sex and attraction. Sex pheromones are released into the cheek gland secretions and the urine of a female cat.

In humans, sex pheromones are invisible and odorless, yet they are still sensed through the nasal passages. If humans do respond to hormones, most likely they use their normal olfactory system.

Mammals, including humans, also give off a cloud of molecules that represent our unique individual "smell" or chemical profile. How do pheromones work in humans? Before going any further, let me answer this. It is known as the vomeronasal organ (VNO). A receptive pheromone will attract you toward it until you are in its presence. Most scientists would say that there is little evidence that humans rely very much upon pheromones as a sexual attractant.
