Animal sexuality

In biology, mating (or mateing in British English) is the pairing of opposite-sex or hermaphroditic organisms, usually for the purposes of sexual reproduction.

Animal sexual behaviour takes many different forms, including within the same species.

Homosexual behavior in animals is sexual behavior among non-human species that is interpreted as homosexual or bisexual.

Polygyny (/pəˈlɪdʒɪniː/; from Neo-Greek πολυγυνία from πολύ- poly- "many", and γυνή gyne "woman" or "wife") is a mating system in which one male lives and mates with multiple females, but each female only mates with a single male.

Patterns of Sexual Behavior, published in 1951, is a work of scientific literature co-authored by Clellan S.

Green Porno is a series of short films on animal sexual behaviour.

The sexually dimorphic nucleus (SDN) is an ovoid, densely packed cluster of large cells located in the medial preoptic area (POA) of the hypothalamus which is believed to be related to sexual behavior in animals.

Non-reproductive sexual behavior is sexual activities animals participate in that do not lead to the reproduction of the species.

The anteroventral periventricular nucleus (AVPV) is a small cluster of cells located in the preoptic area of hypothalamus of the brain that is abundant in nuclear hormone receptors in a sexually dimorphic manner, strongly implicated, in rat models, as being neonatally imprinted and subsequently controlling sex-typical physiology and behaviors.

A few animal studies have suggested that prostitution exists among different species of non-human animals such as Adélie penguins and chimpanzees.

Sexual coercion in animals is the use of violence, threats, harassment, and other tactics to help them forcefully copulate.

Traumatic insemination, also known as hypodermic insemination, is the mating practice in some species of invertebrates in which the male pierces the female's abdomen with his penis and injects his sperm through the wound into her abdominal cavity (hemocoel).

Monogamous pairing in animals refers to the natural history of mating systems in which species pair bond to raise offspring.
