Pheromones, in general, are secreted chemical substances by organisms that trigger a social reaction in the same species. Sex pheromones are a special type of olfactory signal, produced to attract the opposite sex, to encourage mating or to perform some other function closely related to sexual reproduction.
Body odour affects sexual attraction in a number of ways including through human biology, the menstrual cycle and fluctuating asymmetry. The olfactory membrane plays a role in smelling and subconsciously assessing another human's pheromones. [8] It also affects the sexual attraction of insects and mammals.
Sex pheromones have evolved in many species. The many types of pheromones (i.e. alarm, aggregation, defense, sexual attraction) all have a common cause acting as chemical cues to trigger a response. However, sex pheromones are particularly associated with signaling mating behaviors or dominance.
Male-produced sex attractants have been called aggregation pheromones, because they usually result in the arrival of both sexes at a calling site and increase the density of conspecifics surrounding the pheromone source. Most sex pheromones are produced by the females; only a small percentage of sex attractants are produced by males. [7]
Each person produces a unique spread of pheromones that can be identified by others. [2] This differentiation allows the formation of sexual attraction and kinship ties to occur. [2] [17] Sebaceous and apocrine glands become active at puberty. This, as well as many apocrine glands being close to the sex organs, points to a role related to ...

The chemical hormones that function outside the body and play a role in attraction are known as pheromones.
Humans can not only detect, but also assess, and respond to environmental (chemical) olfactory cues—especially those used to evoke behavioral and sexual responses from other individuals, also known as pheromones. Pheromones function to communicate one's species, sex, and perhaps most importantly one's genetic identity.
