Artificial insemination (AI) is the deliberate introduction of semen into a female's vagina or oviduct for the purpose of achieving a pregnancy through fertilisation by means other than copulation. It is the medical alternative to sexual intercourse, or natural insemination.Artificial insemination is a fertility treatment for humans, and is a common practice in the breeding of dairy cattle (see the main article frozen bovine semen) and pigs, and is also used in other animal breeding. Artificial insemination may employ assisted reproductive technology, donated sperm, and/or animal husbandry techniques.
