When we talk about animal instinct, we're often talking about pheromones - chemicals that affect the behaviour of other animals, and make individuals irresistible to the opposite sex during mating season. For decades, debate has raged over whether humans might also release and be susceptible to our own unique pheromones. But a new study has just provided evidence that the two leading ' human sex pheromone ' candidates aren't actually pheromones at all. Until now, researchers had narrowed down the hunt for human pheromones to two chemicals - androstadienone AND , which is found in male sweat and semen, and estratetraenol EST , found in women's urine.

We Just Got More Evidence That The 2 Human 'Sex Pheromones' Don't Actually Exist

Sex pheromones are pheromones released by an organism to attract an individual of the opposite sex , 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.

Human sex pheromones

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.

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.
