Certain secretions attract the opposite sex of the same species which are termed Pheromones.
Pheromones are substances that are secreted to the outside by an individual and received by a second individual of the same species.
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.
