A conception cap can assist to protect semen from the vaginal cavity and allow semen to pool against the cervical os. [8] [9] Around the time of ovulation, a conception cap or cervical cap is filled with semen and placed on a woman's cervical os for several hours to maximize the time the semen is available to fertilise a waiting egg.
The first recorded case of artificial insemination was John Hunter in 1790, who helped impregnate a linen draper's wife. [1] [2] 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.
Sperm sorting by flow cytometry is an established technique in veterinary practice, and in the dairy industry most female cows are artificially inseminated with sorted semen to increase the number of female calves (using sperm sorting is less common in other species of farm animals, however artificial insemination is common). [16] Artificial ...

In France, ART is subsidized in full by national health insurance for women up to age 43, with limits of 4 attempts at IVF and 6 at artificial insemination. Germany tightened its conditions for public funding in 2004, which caused a sharp drop in the number of ART cycles carried out, from more than 102,000 in 2003 to fewer than 57,000 the ...
In 2008, research was done specifically for methods on creating human female sperm using artificial or natural Y chromosomes and testicular transplantation. [18] A UK-based group predicted they would be able to create human female sperm within five years. So far no conclusive successes have been achieved. [3]
Insemination of the surrogate can be either through sex (natural insemination) or artificial insemination. Using the sperm of a donor results in a child who is not genetically related to the intended parent(s). If the intended father's sperm is used in the insemination, the resulting child is genetically related to both him and the surrogate ...
