Many examples exist in animals but their role in humans remains uncertain since adults have no functioning vomeronasal organ, which processes pheromone signals in animals.
What are pheromones in biology?
A pheromone is defined as a chemical or a mixture of chemicals that is released to the exterior by an organism that causes one or more specific reactions in a receiving individual of the same species (Shorey, 1977).

What part of the brain is responsible for detecting pheromones?
