artificial insemination(redirected from Artificial inseminator)
Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.
the deposit of seminal fluid within the vagina or cervix.
artificial insemination that done by artificial means. There are two primary types: Artificial insemination by husband (AIH) involves depositing the husband's or sexual partner's sperm from a specimen, obtained during masturbation, into the vagina, cervical canal, or uterine cavity of the recipient. Donor insemination or Artificial insemination by donor (AID) involves the same techniques but the sperm is from a donor other than the husband or partner.
introduction of semen into the vagina other than by coitus.
Introduction of semen into the vagina or uterus without sexual contact.
artificial insemination (AI)
the introduction of semen into the vagina or uterus by mechanical or instrumental means rather than by sexual intercourse. The procedure is planned to coincide with the expected time of ovulation so that fertilization can occur. Kinds of artificial insemination are artificial insemination-donor (AID) and artificial insemination-husband (AIH). Also called artificial impregnation. See also menstrual cycle.
artificial inseminationThe (non-sexual) instillation of sperm-bearing semen in the vagina, cervix or endocervical canal to fertilise an egg; ± 75,000 women/year (US) undergo AI.
Artificial insemination-related infections
Chlamydia trachomatis, CMV, herpes, gonorrhoea, HBV, HIV, Trichomonas vaginalis.
artificial inseminationReproductive medicine The instillation of sperm-bearing semen in the vagina, cervix, or endocervical canal to fertilize an egg; ± 75,000 ♀/yr–US undergo AI. See Assisted reproduction, Intracervical insemination, Intrauterine insemination, Intratubal insemination.
ar·ti·fi·cial in·sem·i·na·tion(ahr'ti-fish'ăl in-sem'i-nā'shŭn)
The introduction of semen into the vagina other than by coitus.
artificial inseminationA method of achieving pregnancy when normal sexual intercourse is impossible, or when the male partner is sterile. Fresh semen is taken up in a narrow syringe or pipette and injected high into the vagina or into the mouth of the womb. The success rate is high. An example of positive EUGENICS is artificial insemination with sperm from anonymous donors guaranteed to be of high mental or physical calibre. The frozen sperm of certain Nobel Prize winners is stored, for this purpose, by the Repository for Germinal Choice, founded in 1979. See AID, AIH.
artificial insemination (AI)the introduction of spermatozoa into the reproductive tract of a female animal without COPULATION in order to achieve fertilization. The method is used routinely in animal breeding to transfer genetic material over large distances and to achieve many fertilizations in different females from one ejaculation of semen. In the case of humans, AI is used sometimes in attempts to achieve fertilization where normal methods have failed.
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.
