There are some perfumes on the market that contain human pheromone, such as Human Euphoria perfume for women and Human Sex Pheromone Spray, but many pheromone perfumes use a blend of synthetic pheromones. Pheromones are odorless chemicals that the body produces naturally to send a signal to someone else and are usually mixed with perfumes or can be worn naturally unscented.
The role of human pheromones in sexual attraction has been debated, according to WebMD. Increase in sexual attraction has been documented in studies since the pheromone was discovered in 1986. A study by Dr. Winifred Cutler, the co-discoverer of pheromones in armpit sweat, found that 74 percent of people using a commercial pheromone have more hugs, kisses and sex.
