As the level of oxytocin increases so does sexual motivation. Popular discussions of bonobos are a frequently cited example. Each female copulates with many males, and vice versa. Many animals that form pairs to mate and raise offspring regularly engage in sexual activities with extra-pair partners. When they find a female they bite into her skin, releasing an enzyme that digests the skin of their mouth and her body and fusing the pair down to the blood-vessel level. Copulation zoology Copulation is the union of the male and female sex organs , the innate sexual activity specifically organized to transmit male sperm into the body of the female. Current research frequently expresses views such as that of the Natural History Museum at the University of Oslo , which in held an exhibition on animal sexuality: It is known as the Bruce effect.

While oxytocin plays a major role in parent child relationships, it is also found to play a role in adult sexual relationships. Polygynandry Polygynandry occurs when multiple males mate indiscriminately with multiple females. They can no longer assume social monogamy determines how genes are distributed in a species. Social monogamy, sexual monogamy, and genetic monogamy can occur in different combinations. Zoologists and biologists now have evidence that monogamous pairs of animals are not always sexually exclusive. This extreme sexual dimorphism ensures that, when the female is ready to spawn, she has a mate immediately available. This is sometimes stated as "animals mate only for reproduction". In bonobos, the amount of promiscuity is particularly striking because bonobos use sex to alleviate social conflict as well as to reproduce[ citation needed ]. Polygamy in both sexes has been observed in red flour beetle Tribolium castaneum. Some species, such as the Rana Clamitans green frog , spend from June to August defending their territory. Neither male nor female montane voles release high quantities of oxytocin or vasopressin when they mate. In some species, notably those with harem -like structures, only one of a few males in a group of females will mate. Technically, polygyny in sociobiology and zoology is defined as a system in which a male has a relationship with more than one female, but the females are predominantly bonded to a single male. When montane voles mate, they form no strong attachments, and separate after copulation. A combination of terms indicates examples where levels of relationships coincide, e. Prairie voles have a greater number of oxytocin and vasopressin receptors compared to montane voles, and are therefore more sensitive to those two neurohormones. Furthermore, the oxytocin levels of the couples correlate positively; when the oxytocin secretion of one increases the other one also increases. It is therefore reasonable to assume that sexual intercourse may be linked with a positive experience for female animals. In some species, such as redlip blennies , both polygyny and polyandry are observed. The lower the rates of genetic monogamy among socially monogamous pairs, the less of a role social monogamy plays in determining how genes are distributed among offspring. As a consequence, the mother rat solicits males to the nest but simultaneously becomes aggressive towards them to protect her young. Copulation zoology Copulation is the union of the male and female sex organs , the innate sexual activity specifically organized to transmit male sperm into the body of the female. As the level of oxytocin increases so does sexual motivation. In some species of planarians , sexual behaviour takes the form of penis fencing. The remaining males will move up a rank in the hierarchy. Polygyny in nature Polygyny occurs when one male gets exclusive mating rights with multiple females. It is known as the Bruce effect.

    In general, studies have suggested that dopamine is involved in sexual incentive motivation, oxytocin and melanocortins in sexual attraction, and noradrenaline in sexual arousal.

    Two examples of systems in primates are promiscuous mating chimpanzees and bonobos. The actual incidence of social monogamy varies greatly across different branches of the evolutionary tree.
