===Spread of infectious disease===
By [[sperm washing]], the risk that a chronic disease in the individual providing the sperm would infect the birthing parent or offspring can be brought to negligible levels.

If the sperm donor has [[hepatitis B]], The Practice Committee of the American Society for Reproductive Medicine advises that sperm washing is not necessary in IVF to prevent transmission, unless the birthing partner has not been effectively vaccinated.<ref>{{cite journal |author1=Practice Committee of American Society for Reproductive Medicine |date=November 2008 |title=Hepatitis and reproduction |journal=Fertility and Sterility |volume=90 |issue=5 Suppl |pages=S226–S235 |doi=10.1016/j.fertnstert.2008.08.040 |pmid=19007636 |doi-access=free}}</ref><ref name="Lutgens2009">{{cite journal |vauthors=Lutgens SP, Nelissen EC, van Loo IH, Koek GH, Derhaag JG, Dunselman GA |date=November 2009 |title=To do or not to do: IVF and ICSI in chronic hepatitis B virus carriers |journal=Human Reproduction |volume=24 |issue=11 |pages=2676–2678 |doi=10.1093/humrep/dep258 |pmid=19625309 |doi-access=free}}</ref> In women with hepatitis B, the risk of [[vertical transmission]] during IVF is no different from the risk in spontaneous conception.<ref name="Lutgens2009" /> However, there is not enough evidence to say that [[Intracytoplasmic sperm injection|ICSI]] procedures are safe in women with hepatitis B in regard to vertical transmission to the offspring.<ref name="Lutgens2009" />

Regarding potential spread of [[HIV/AIDS]], Japan's government prohibited the use of IVF procedures in which both partners are infected with HIV. Despite the fact that the ethics committees previously allowed the [[Ogikubo, Tokyo]] Hospital, located in Tokyo, to use IVF for couples with HIV, the [[Ministry of Health, Labour and Welfare (Japan)|Ministry of Health, Labour and Welfare]] of Japan decided to block the practice. Hideji Hanabusa, the vice president of the Ogikubo Hospital, states that together with his colleagues, he managed to develop a method through which scientists are able to remove HIV from sperm.<ref>{{cite web |date=21 July 2008 |title=Japan Bans in Vitro Fertilisation for HIV Couples |url=http://www.infoniac.com/health-fitness/japan-bans-in-vitro-fertilization-for-hiv-couples.html |publisher=Infoniac.com |access-date=3 August 2013 |archive-date=19 September 2013 |archive-url=https://web.archive.org/web/20130919204101/http://www.infoniac.com/health-fitness/japan-bans-in-vitro-fertilization-for-hiv-couples.html |url-status=dead }}</ref>

In the United States, people seeking to be an embryo recipient undergo infectious disease screening required by the [[Food and Drug Administration (United States)|Food and Drug Administration]] (FDA), and reproductive tests to determine the best placement location and cycle timing before the actual embryo transfer occurs. The amount of screening the embryo has already undergone is largely dependent on the genetic parents' own IVF clinic and process. The embryo recipient may elect to have their own [[embryologist]] conduct further testing.
