artificial insemination (AI),

the introduction of semen into the vagina or uterus by mechanical or instrumental means rather than by sexual intercourse.

Kinds of artificial insemination are artificial insemination-donor (AID) and artificial insemination-husband (AIH). Also called artificial impregnation. See also menstrual cycle.

artificial insemination

the implanting of live spermatozoa into the genital tract of the female. The diluted or otherwise treated semen is usually deposited in the body of the uterus because of the higher fertility rate obtained, but insemination into the uterine cervix or even the vagina may be practiced. Although insemination is usually carried out via the vagina transperitoneal insemination may be the technique used in animals whose anatomy precludes a satisfactory vaginal approach. See also ai.

avian artificial insemination

is practiced extensively; it is used in turkeys where selection for heavy breast muscle has bred male turkeys unable to impregnate large numbers of females. The procedure is approximately the same as in other species with the exception that the semen must be fresh; a technique for freezing is not available.
