[1] [2] Some animal sexual behaviour involves competition, sometimes fighting, between multiple males. Females often select males for mating only if they appear strong and able to protect themselves. The male that wins a fight may also have the chance to mate with a larger number of females and will therefore pass on his genes to their ...
In fowl, females can be physically injured during forceful copulations. Also, semen transferred from the males can contain pathogens and fecal matter, which can lead to disease and decrease female fitness. [24] In elephant seals, physical injury happens very often. In fact, mating leads to 1 in every 1,000 female elephant seals getting killed. [22]
Lordosis behavior (/ l ɔːr ˈ d oʊ s ɪ s / [1]), also known as mammalian lordosis (Greek lordōsis, from lordos "bent backward" [1]) or presenting, is the naturally occurring body posture for sexual receptivity to copulation present in females of most mammals including rodents, elephants, cats, and humans.
A bull elephant in musth, wild or otherwise, is extremely dangerous to humans, other elephants, and other species. Bull elephants in musth have killed keepers/mahouts, as well as other bull elephants, female elephants, and calves (the last usually inadvertently or accidentally in what is often called "herd infighting").

Male impalas fighting during the rut or breeding season. The rut (from the Latin rugire, meaning "to roar") is the mating season of certain mammals, which includes ruminants such as deer, sheep, camels, goats, pronghorns, bison, giraffes and antelopes, and extends to others such as skunks and elephants.
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 ...
Male elephant seals fighting at Piedras Blancas, California. Dominant male elephant seals arrive at potential breeding sites in spring, and fast to ensure that they can mate with as many females as possible. [18] Male elephant seals use fighting, vocal noises, and different positions to determine who will be deemed the dominant male.
The second breeding female will receive fewer resources from the male than the first breeding female. However, if the bigamous threshold is higher than the second female's original resource threshold, the female will enter into a polygynous mating system, since she would still benefit from acquiring more resources.
