Pheromones used in Perfume

Pheromones are odorless chemicals that cause arousal and attraction in people. Either the olfactory epithelium (most likely) or the vomeronasal organ, which is located in the nose and conveys messages to the higher cortical regions of the brain, potentially could mediate pheromone signals. The pheromones that affect males and females are distinct from each other. There's a great deal of scientific research that suggests that pheromones really do work, and a number of perfume makers are incorporating pheromones into some of their fragrances. There are also several companies that sell synthetic pheromones on their own so you can add them to your own perfume.




Women's perfume laced with synthetic pheromones acts as a sexual magnet and increases the sexual attractiveness of women to men, San Francisco State University researchers conclude in a study appearing in the current issue of the quarterly journal Physiology and Behavior.

The study, the first of its kind to independently test a sex attractant pheromone for women, showed that of the 36 women tested, 74 percent of those wearing their regular perfume with the pheromone saw an overall increase in three or more of the following sociosexual behaviors: frequency of kissing, heavy petting and affection, sexual intercourse, sleeping next to their partner, and formal dates with men.

The study was conducted for 14 weeks in 2000. Thirty-six women were recruited on campus through psychology and human sexuality classes and asked to participate in an experiment described as testing a pheromone that would "increase romance in their lives." The criteria for participation called for women who were heterosexual, regularly menstruating, neither married nor co-habiting with a man, not currently using an oral contraceptive and in good health.
