Pheromones are similar to hormones but work outside of the body. They induce activity in other individuals, such as sexual arousal. Most insects use pheromones to communicate. Some chemicals have been investigated for pheromone actions in humans but evidence is weak.
Do humans give off pheromones?
Pheromones in humans may be present in bodily secretions such as urine, semen or vaginal secretions, breast milk and potentially also saliva and breath, yet most attention thus far has been directed toward axillary sweat. The concentration of 16-androstenes is much higher in male compared to female axillary sweat.
What are examples of pheromones?
