artificial insemination, technique involving the artificial injection of sperm-containing semen from a male into a female to cause pregnancy. Artificial insemination is often used in animals to multiply the possible offspring of a prized animal and for the breeding of endangered species. Prepared semen can be preserved for long periods by refrigeration, and it is frequently shipped over great distances.

The method has also been used in humans, when traditional fertilization cannot be achieved (see infertility infertility, inability to conceive or carry a child to delivery.

It has become a significant issue in recent years, particularly in debates revolving around surrogate motherhood, in which a woman agrees to bear a child for another couple through the use of artificially inseminated sperm from the husband (see surrogate mother surrogate mother, a woman who agrees, usually by contract and for a fee, to bear a child for a couple who are childless because the wife is infertile or physically incapable of carrying a developing fetus.

Likewise, there have been debates over the rights of sperm donors. Other debates on the subject have centered around the ethics of artificial insemination among humans, with critics decrying the practice as a perversion of science or pointing to the possible abuse of the process for purposes of eugenics eugenics (y

artificial insemination

Introduction of semen into a female's vagina or cervix by means other than sexual intercourse. First developed for animal breeding in the early 20th century in Russia, it is now also used to induce pregnancy in women whose partners cannot impregnate them. The partner's (or other donor's) semen is inserted with a syringe. Though reasonably successful, artificial insemination in humans raises moral issues that are not yet fully resolved. In livestock, deep-frozen semen from a male animal can be stored for long periods without losing its fertility, thus allowing a single bull to sire as many as 10,000 calves a year.
