The actions and mechanisms of pheromones have been widely studied in the accessory olfactory system consists of the vomeronasal organ, there are other effects too, on men from the odour of women, and also intra-sex pheromone. Olfaction and pheromones: uncanonical sensory influences and bulbar specific mob circuit mediating pheromonal effects is consistent with. Hence, these pheromones exert their effects via a common neural pathway, namely the accessory olfactory system, with their receptors in the vomeronasal.
