Artificial insemination
pregnancy through in vivo fertilization

Artificial insemination is the deliberate introduction of sperm into the cervix or uterine cavity for the purpose of achieving pregnancy through in vivo fertilization by means other than sexual intercourse. It is a fertility treatment for humans, and is a common practice in animal breeding, including cattle (see frozen bovine semen) and pigs.
Artificial insemination may employ assisted reproductive technology, sperm donation and animal husbandry techniques. Artificial insemination techniques available include intracervical insemination (ICI) and intrauterine insemination (IUI). Where gametes from a third party are used, the procedure may be known as 'assisted insemination'.

History
The first recorded case of artificial insemination was by Lazzaro Spallanzani in 1784, who performed it on a dog. It was followed in 1790 by John Hunter, who helped impregnate a linen draper's wife. 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. The case was reported 25 years later in a medical journal. The sperm bank was developed in Iowa starting in the 1950s in research conducted by University of Iowa medical school researchers Jerome K. Sherman and Raymond Bunge.
This brief starts where responsible research should: with the source description of “Artificial insemination” as pregnancy through in vivo fertilization. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as pregnancy through in vivo fertilization. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q207122. The Library of Congress control number is sh85008174. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1784, 1790 and 1884.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
