Editing Body odor (section)

====Humans====
In humans, body odor serves as a means of chemosensory signal communication between members of the species. These signals are called [[pheromone]]s and they can be transmitted through a variety of mediums. The most common way that human pheromones are transmitted is through bodily fluids. Human pheromones are contained in sweat, semen, vaginal secretions, breast milk, and urine.<ref name="lund-4" /> The signals carried in these fluids serve a range of functions from reproductive signaling to infant socialization.<ref name="Damon_2021">{{cite journal | vauthors = Damon F, Mezrai N, Magnier L, Leleu A, Durand K, Schaal B | title = Olfaction in the Multisensory Processing of Faces: A Narrative Review of the Influence of Human Body Odors | journal = Frontiers in Psychology | volume = 12 | pages = 750944 | date = 2021-10-05 | pmid = 34675855 | pmc = 8523678 | doi = 10.3389/fpsyg.2021.750944 | doi-access = free }}</ref> Each person produces a unique spread of pheromones that can be identified by others.<ref name="Grammer_2005">{{cite journal | vauthors = Grammer K, Fink B, Neave N | title = Human pheromones and sexual attraction | journal = European Journal of Obstetrics, Gynecology, and Reproductive Biology | volume = 118 | issue = 2 | pages = 135–142 | date = February 2005 | pmid = 15653193 | doi = 10.1016/j.ejogrb.2004.08.010 }}</ref> This differentiation allows the formation of sexual attraction and kinship ties to occur.<ref name="Grammer_2005" /><ref name="Porter_1985">{{cite journal | vauthors = Porter RH, Cernoch JM, Balogh RD | title = Odor signatures and kin recognition | journal = Physiology & Behavior | volume = 34 | issue = 3 | pages = 445–448 | date = March 1985 | pmid = 4011726 | doi = 10.1016/0031-9384(85)90210-0 | s2cid = 42316168 }}</ref>

[[Sebaceous]] and [[apocrine gland]]s become active at [[puberty]]. This, as well as many apocrine glands being close to the sex organs, points to a role related to mating.<ref name="Oxford2007" /> Sebaceous glands line the human skin while apocrine glands are located around body hairs.<ref name="lund-4" /> Compared to other primates, humans have extensive axillary hair and have many odor producing sources, in particular many apocrine glands.<ref name="AEP" /> In humans, the apocrine glands have the ability to secrete [[pheromone]]s. These steroid compounds are produced within the peroxisomes of the apocrine glands by enzymes such as mevalonate kinases.<ref>{{cite journal | vauthors = Rothardt G, Beier K | title = Peroxisomes in the apocrine sweat glands of the human axilla and their putative role in pheromone production | journal = Cellular and Molecular Life Sciences | volume = 58 | issue = 9 | pages = 1344–1349 | date = August 2001 | pmid = 11577991 | doi = 10.1007/PL00000946 | s2cid = 28790000 | pmc = 11337405 }}</ref>
