When animal sexual behaviour is reproductively motivated, it is often termed mating or copulation; for most non-human mammals, mating and copulation occur at oestrus (the most fertile period in the mammalian female's reproductive cycle), which increases the chances of successful impregnation.
The all-female Whiptail lizard species Aspidoscelis neomexicanus (center), which reproduces via parthenogenesis, is shown flanked by two sexual species having males, A. inornatus (left) and A. tigris (right). Research has shown that simulated mating behavior increases fertility for Aspidoscelis neomexicanus. One female lies on top of another ...
In elephants, the breeding season is less pronounced than in ungulates and it usually spikes when the rains season occurs or shortly thereafter. [28] [1] The rut is observed in both African and Asian elephants and it is referred to as musth. [29] Its meaning is derived from the Urdu word mast meaning intoxication. The most prominent ...
Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals.

Human–animal marriage is a marriage between a human and a non-human animal. This topic has appeared in mythology and magical fiction . [ 1 ] In the 21st century, there have been numerous reports from around the world of humans marrying their pets and other animals.
Zoophilia is a paraphilia in which a person experiences a sexual fixation on non-human animals. [1] [2] [3] Bestiality instead refers to cross-species sexual activity between humans and non-human animals. [a] Due to the lack of research on the subject, it is difficult to conclude how prevalent bestiality is. [5]
In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. [ 1 ] [ 2 ] This is an aspect of mating . Many aquatic animals use external fertilization , whereas internal fertilization may have developed from a need to maintain gametes in a liquid ...
According to Gordon G. Gallup, as a form of adapting to multiple mating in females, human penile shape is indicative of an evolutionary history of polyandry. Male humans evolved to have a wedge- or spoon-shaped glans and to perform repeated thrusting motions during copulation in order to draw foreign semen back away from the cervix and thus to ...
