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.
Pheromones are chemical messengers produced and emitted by the body that contribute significantly to interpersonal attraction. [8] The two types of pheromones include signal and primer, each playing a distinct role in human behavior. Signal pheromones act as attractants and repellents; they are classified short-term behavioral pheromones.

Pheromones are often not pure substances, but so-called pheromone cocktails consisting of various components.
