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. While humans are highly dependent upon visual cues, smells can also play a role in sociosexual behaviors .
Pheromones are chemical messengers produced and emitted by the body that contribute significantly to interpersonal attraction. [8] The two types of pheromones include signal and primer, each playing a distinct role in human behavior. Signal pheromones act as attractants and repellents; they are classified short-term behavioral pheromones.
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]
Compared to other primates, humans have extensive axillary hair and have many odor producing sources, in particular many apocrine glands. [18] In humans, the apocrine glands have the ability to secrete pheromones. These steroid compounds are produced within the peroxisomes of the apocrine glands by enzymes such as mevalonate kinases.

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 ...
[2] It is usually used in the field of chemical ecology to encompass pheromones, allomones, kairomones, attractants and repellents. [1] [3] Many insects, including parasitic insects, use semiochemicals. Pheromones are intraspecific signals that aid in finding mates, food and habitat resources, warning of enemies, and avoiding competition.
Pigs communicate through pheromones commonly and also display main olfactory epithelium response to some pheromones. Additionally in mice we see vomeronasal response from odors not produced by animals. Some mutant mice defective in VNO activity continue to display activity that is indicative of pheromone communication.
The reproductive system of an organism, also known as the genital system, is the biological system made up of all the anatomical organs involved in sexual reproduction.Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system. [1]
