Horse breeding is reproduction in horses, and particularly the human-directed process of selective breeding of animals, particularly purebred horses of a given breed. Planned matings can be used to produce specifically desired characteristics in domesticated horses. Furthermore, modern breeding management and technologies can increase the rate ...
The term is also used in the context of third-party insemination, where a male who is not the woman's usual sexual partner (i.e., a sperm donor) fathers a child for the woman by providing his sperm through sexual intercourse rather than by providing his sperm for it to be used to produce a pregnancy in the woman by artificial means. [10]
The first recorded case of artificial insemination was John Hunter in 1790, who helped impregnate a linen draper's wife. [1] [2] The first reported case of artificial insemination by donor occurred in 1884: William H. Pancoast, a professor in Philadelphia, took sperm from his "best looking" student to inseminate an anesthetized woman without her knowledge.
A comparative study between women who had consensual vaginal sex and victims of rape found that in consensual sex, 6.9 percent of women had genital injuries. Among women who were raped, 22.8 percent suffered genital injuries. [74] In men, there is a risk of penile rupture if the penis is bent when erect. This is a case of medical emergency.
Amongst the land mammals, other than humans, only bonobos mate in a face-to-face position, [136] [better source needed] as the females' anatomy seems to reflect, [117] although ventro-ventral copulation has also been observed in Rhabdomys. [137] Some sea mammals copulate in a belly-to-belly position.
The woman seems pleased when she sees how much semen her sexual partner ejaculates. The man then rubs his penis focusing on the glans. He ejaculates for the second round into the woman's mouth and onto her face while she lies on her back. Note that semen from two ejaculations differs.
Following traumatic insemination, sperm can migrate through the hemolymph to the female's ovaries, resulting in fertilization. The exact mechanics vary from taxon to taxon. In some orders of insects, the male genitalia enters the female's genital tract, and a spine at its tip pierces the wall of the female's bursa copulatrix. In others, the ...
