Sex pheromones provide an important means of communication to unite individuals for successful reproduction. Although sex pheromones are highly diverse across animals, these signals fulfil common fundamental roles in enabling identification of a mating partner of the opposite sex, the appropriate species and of optimal fecundity. In this review, we synthesize both classic and recent investigations on sex pheromones in a range of species, spanning nematode worms, insects and mammals. These studies reveal comparable strategies in how these chemical signals are produced, detected and processed in the brain to regulate sexual behaviours. Elucidation of sex pheromone communication mechanisms both defines outstanding models to understand the molecular and neuronal basis of chemosensory behaviours, and reveals how similar evolutionary selection pressures yield convergent solutions in distinct animal nervous systems.

Do Pheromones Play a Role in Our Sex Lives?
Sex pheromone - Wikipedia
Sex pheromones are pheromones released by an organism to attract an individual of the same species, encourage them to mate with them, or perform some other function closely related with sexual reproduction. Sex pheromones specifically focus on indicating females for breeding, attracting the opposite sex, and conveying information on species, age, sex and genotype. Non-volatile pheromones, or cuticular contact pheromones, are more closely related to social insects as they are usually detected by direct contact with chemoreceptors on the antennae or feet of insects. Insect sex pheromones have found uses in monitoring and trapping of pest insects. Sex pheromones have evolved in many species. The many types of pheromones i. However, sex pheromones are particularly associated with signaling mating behaviors or dominance.
Love might be in the air on Valentine's Day , metaphorically speaking. But scientists have long debated whether love—or, at least, sexual attraction—is literally in the air, in the form of chemicals called pheromones. Creatures from mice to moths send out these chemical signals to entice mates. And if advertisements about pheromone-laden fragrances are to be believed, one might conclude that humans also exchange molecular come-hithers. Still, after decades of research, the story in humans is not quite so clear.
If we stripped away our material possessions, our clothes, and all the things we surround ourselves with, what is left? Evolution tells us that at one point in time, we were connected to the earth and our instincts in order to survive. Pheromones, for instance, are chemicals that give us a sense of subconscious smell. These chemicals help us naturally connect with those around us, especially in terms of our sexual attraction to others. Mike Anderson, Ph.
