An inherent difficulty in studying human pheromones is the need for cleanliness and odorlessness in human participants. [3] Experiments have focused on three classes of putative human sex pheromones: axillary steroids, vaginal aliphatic acids and stimulators of the vomeronasal organ.
A pheromone (from Ancient Greek φέρω (phérō) 'to bear' and hormone) is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. [1]
Mammalian pheromones can elicit both long-lasting effects that alter the hormone levels of the recipient animal, and short-term effects on its behavior. [78] For example, detection of male pheromones by female mice has been found to encourage onset of puberty, however the detection of female pheromones have been found to delay the onset of puberty.
No study has led to the isolation of true human sex pheromones. [9] [10] While humans are highly dependent upon visual cues, when in close proximity, smells also play a role in sociosexual behaviors. An inherent difficulty in studying human pheromones is the need for cleanliness and odorlessness in human participants. [11]
Pregnadienedione (PDD), or pregna-4,20-dien-3,6-dione, is a steroid and pherine, or synthetic pheromone. [1] [2] PDD has been found to activate the vomeronasal organ in men.[1] [2] Moreover, inhalation by men has been found to affect autonomic and central function and to lower luteinizing hormone and testosterone levels, while inhalation by women has few or no effects.
