Many countries have laws, regulations, or recommendations that effectively prohibit donations of blood or tissue for organ and corneal transplants from men who have sex with men (MSM), a classification of males who engage or have engaged in sex with other males, irrespective of their sexual activities with same-sex partners and of whether they identify themselves as bisexual or gay. Temporary restrictions are sometimes called "deferrals", since blood donors who are found ineligible may be found eligible at a later date. However, many deferrals are indefinite meaning that donation are not accepted at any point in the future, constituting a de facto ban. Even men who have monogamous relations with their same-sex partner are found ineligible.
Restrictions vary from country to country, and in some countries practice of protected sex or periods of abstinence are not considered. The restrictions affect these men and, in some cases, any female sex partners. They do not otherwise affect other women, including women who have sex with women. With regard to blood donation, the United States Food & Drug Administration (FDA) enforces a three-month deferral period for MSM and women who have sex with MSM. In Canada, the deferral period for MSM blood donors was decreased to 3 months in June 2019. Meanwhile, for tissues such as corneas, the MSM deferral period is five years in the United States and 12 months in Canada.
Many LGBT organizations view the restrictions on donation as based on homophobia and not based on valid medical concern since donations are rigorously tested to rule out donors that are infected with known viruses such as HIV, hepatitis B, and hepatitis C. They state the deferrals are based on stereotypes. Proponents of the lifetime restriction defend it because of the asserted risk of false negative test results and because the MSM population in developed countries tends to have a higher prevalence of HIV/AIDS infection. The UK government advisory committee, SABTO, stated in 2013 that "the risk of transfusion of HIV infected blood would increase if MSM were allowed to donate blood". In July 2017 however, the UK government reduced the one year deferral window to three months, to take effect in the following months, resulting from SABTO's updated conclusions that "new testing systems were accurate and donors were good at complying with the rules". Furthermore, NHS Blood and Transplant are in the process of investigating how possible it is for MSM, depending on degree of risk, to donate without even the three-month deferral. NHS has said that there is currently a limited amount of data on effective ways of conducting such risk assessments, and that the initial steps of scoping, evidence gathering and testing will potentially take up to two years to complete.
Advocates for change to MSM prohibitions point out that screening of donors should focus on sexual behavior as well as safe sex practices since many MSM may always have protected sex, be monogamous, or be in other low risk categories. Some groups in favor of lifting the restrictions support a waiting period after the blood is donated when the donor is considered to have had behavior considered higher risk, and before it is used, to match the blood bank's window of testing methods. While HIV is reliably detected in 10 to 14 days with RNA testing, older testing methods provide accuracy for only up to 98% of positive cases after three months.
Since 1982, the risk for HIV infection transmitted via transfusion has been almost eliminated by the use of questionnaires to exclude donors at higher risk for HIV infection and performing screening tests with highly sensitive equipment to identify infected blood donations. According to the 2015 surveillance report by Canadian Blood Services, the risk of HIV transfusion-transmitted infection was fairly low: in 1 in 21.4 million donations.Contaminated blood put haemophiliacs at massive risk and severe mortality, increasing the risk of common surgical procedures. People who contracted HIV from a contaminated blood transfusion include Isaac Asimov, who received a blood transfusion following a cardiac surgery.
In the United States the population most affected by HIV includes gay, bisexual, and other MSM. Of the 38,739 new HIV diagnoses in the US and dependent areas in 2017, 70% consisted of adult and adolescent gay and bisexual men. Although approximately 492,000 sexually active gay and bisexual men are at high risk for HIV, there are more tools to prevent HIV than ever before.
Since 2021, the deferral period within Australia was reduced from 1 year to 3 months without PrEP. Gay and bi men on PrEP still have a 1-year deferral period – however can donate plasma after 3 months.
Since June 2019, a 3-month deferral period for gay and bi men donating blood was implemented throughout Canada. Canadian Blood Services plans to end its deferral period on September 30, 2022. Since October 2021, it was announced that monogamous gay and bi men can legally donate plasma only – without any waiting periods in some cities of Alberta and Ontario.Quebec have their own jurisdictional blood donation policies, plasma donations will be allowed from Autumn 2022 and other donations should be allowed by Spring 2023.
 Between February 1, 2020, to March 16, 2022 France implemented a policy that allows gay and bi men to donate blood after a 4-month deferral period. Since March 16, 2022 there is no deferral period for gay and bi men within France to donate blood.
 Since September 2021, gay and bisexual men are allowed to donate blood if they live in a permanent monogamous relationship. Sexual contact between men outside of such relationships will lead to exclusion for four months.
The policy implemented in Denmark proper also applies to Greenland (cf. The Office of the medical director of Health of Greenland). Transfusion Medicine Standards published by the Danish Society for Clinical Immunology applies.
 On 16 January 2017 Ireland have lifted the lifetime ban on MSM blood donations switching to 12 month deferral. Since March 28, 2022, the 4 month deferral period for gay and bi men to donate blood within the Republic of Ireland went into effect.
^ abcdPeople of any sexual orientation involved in any kind of sexual activity are welcome to donate blood, if they are confident that their sexual behaviour is safe and does not expose them to sexually transmitted diseases by e.g. unprotected sex with non-trusted partners, regardless of sexual orientation.
Individuals are requested to fill a "Yes/No" questionnaire about their sexual life. Direct questions like "Have you ever had any sexual intercourse with someone from your same sex?" could appear.

Several European countries do not have deferral policies for men who have sex with men (MSM). The donation is allowed if the donor has not had a risky sexual encounter, but not depending on the sexual orientation of the donor. For example, in Italy, the questionnaire item for sexual behavior is symmetrical with respect to homosexual, heterosexual and bisexual intercourses and mentions them explicitly, as well as all points of sexual contact (oral, genital, anal), and does not mention usage of protection.
The UK since November 2017 has implemented a 3-month deferral policy on all gay/bi men who want to donate their blood. However, this did not apply to Northern Ireland until 2020. The Advisory Committee on the Safety of Blood, Tissues and Organs recommended the policy change after a study concluded that a total ban may breach equality legislation and that the risk of HIV reaching the blood supply would only increase by approximately 2%. In December 2020, it was announced that the UK would move to a personalised sexual behaviour risk assessment and scrap the deferral period specific to MSM.
In Ireland, MSM may donate blood if they have not engaged in oral or anal sex with another man at least 12 months prior to a donation. This policy came into effect from 16 January 2017. On 27 July 2015, Tomás Heneghan, a 23-year-old University of Limerick student and journalist from Galway, began a legal challenge in the High Court against the permanent deferral imposed on MSM donors. He argued that the questionnaire and interview process used by the IBTS does not adequately assess the risk of disease transmission posed by his donation. He claims this is in breach of EU law. He said that both failed to consider the length of time between a donor's last sexual experience and the end of a "window period" in which infections are sometimes not detected. Heneghan's previous sexual activity posed no risk of infection, according to HSE-approved advice and he said the service had no evidence upon which it could legitimately impose a life-long ban on him donating blood. Following several adjournments of the case to allow the blood service and Department of Health to examine and develop the donation policies, in late June 2016 the Irish Blood Transfusion Service recommended that the lifetime ban on MSM be reduced to a 12-month ban. Later that week the Minister for Health Simon Harris agreed to the recommendations and announced the reduction would take place. However no timeline was reported for the implementation of the new policies.
On 26 July 2016, Tomás Heneghan dropped his High Court challenge against the service as an end to the lifetime deferral on MSM blood donors had been announced in the interim. Heneghan then wrote about his experiences of challenging the ban in a number of national media outlets. On 2 October 2016, it was reported that Minister Harris would implement the new policy from 16 January 2017, almost seven months after he announced the policy change. On 16 January 2017, Heneghan (now 25) attended a blood donation clinic in D'Olier Street, Dublin and became the first man who has had sex with another man to donate blood openly in the Republic of Ireland since the lifetime deferral policy was first introduced in the 1980s. However he also criticised the new 12-month deferral policy on MSM and called on Ireland's Health Minister to initiate a review of the IBTS and replace the 12-month deferral period for MSM with no deferral or a 3-month deferral on all donors following sexual intercourse.
On 20 May 2019, Heneghan (27) initiated a fresh legal challenge in the High Court against the blanket deferral on men who have had oral or anal sex with another man in the previous 12-month period.
Heneghan claims he cannot understand the reasoning behind the IBTS policy and argues that the questionnaire does not enable the IBTS to make a full evaluation of the level of risk presented by an individual donor due to their sexual behaviour. He also states that according to the IBTS's own website, there is a window period following infection during which HIV and hepatitis may not be detected in the blood and that this window is seven days for HIV and 16 days for hepatitis. He claims that a far less onerous restriction could be imposed rather than the 12-month deferral, which would protect blood recipients. He claims the decision to place an "automatic deferral" on him is unlawful and in breach of EU law and European communities regulations on the quality and safety of human blood products and that the policy is disproportionate, discriminates against homosexual and bisexual men, and breaches his constitutional rights and rights under the European Convention on Human Rights. The case is due to return to the court in July 2019.
In July 2019, a gay man in Ireland filed two formal complaints with the European Commission against the Department of Health and the Irish Blood Transfusion Service, and the Northern Ireland Blood Transfusion Service (the only part of the United Kingdom to maintain a 12-month deferral policy for MSM) over the MSM one-year deferral policy. The man, who has chosen to have his complaints examined by the Commission anonymously, is alleging the ban in both jurisdictions violates a number of European Union laws, including two European Union Directives covering the standards of quality and safety for the collection of blood by EU member states, as well as provisions contained in both the EU Charter of Fundamental Rights and the European Convention on Human Rights. The commission has informed the man his complaints will now be considered in light of EU law.
A similar policy exists in the rest of the European Union and is the prevailing interpretation of the European Union Directive 2004–33/EC article 2.1 on donor deferrals. The policy, however, is not very specific and refers to "high risk sexual contact". The UK interprets the directive to include all forms of homosexual sex as falling within 2.2.2 of Annex III to the directive "Persons whose behaviour or activity places them at risk of acquiring infectious diseases that may be transmitted by blood", requiring a deferral based on the window period for the diseases involved, and sets this at 12 months, despite the Annex suggesting 6 months for risk of exposure to hepatitis B. Hélder Trindade, President of the Portuguese Institute of Blood and Transplantation (IPST), stated in 2015 that sexually abstinent homosexuals may give blood, but that MSM is definitely seen as a risk factor. From March 2022, the Republic of Ireland will reduce the deferral period from 1 year to 4 months.
In Finland, the parliamentary ombudsman launched an investigation on the possible unconstitutionality of the lifetime ban in January 2006. In June 2008, it was concluded that the ban was not unlawful in Finland as it is based on "appropriately reasoned epidemiological information" and because it is related to sexual behaviour rather than sexual orientation. The ombudsman added that people over the age of 65 and people who lived in Britain during the bovine spongiform encephalopathy (mad cow disease) outbreak are also screened out during blood donor interviews. In December 2013, the Finnish Red Cross blood service announced it was lifting the ban and introducing a one-year deferral instead. In 2021, the deferral period in Finland was reduced to 4 months.
In July 2016, France implemented a 1-year deferral period policy on all gay and bisexual men donating blood. Then the blood MSM deferral policy implemented in France was lowered to 4 months effective on February 1, 2020.
At the formation of the New Zealand Blood Service (NZBS) in 1998, the deferral period had been 10 years, but was reduced to 5 years in 2009. This was following an independent review of blood donation criteria in 2007–2008 which found no significant difference in risk of the blood supply for deferral period of 5 years compared to 10 years.
In 2014, the NZBS dropped the ban period from 5 years to 1 year following the recommendation of Medsafe. Their decision was mainly caused by new information about HIV transmission in Australia which already had a one-year deferral period. The 1 year deferral commenced 15 December 2014. On 14 December 2020 the NZBS reduced the deferral to 3 months.
The 3 month deferral period for MSM is on par with the 3-month deferral period for several other behavioural categories carrying a higher probability of unrecognised HIV infection, such as persons engaging in sex work and people who have resided in a country which has a high (1% or more) HIV prevalence.
In the US, the Food and Drug Administration (FDA) issues donor deferral recommendations to blood establishments. The guidance as of 2020 is to "Defer for 3 months from the most recent sexual contact, a man who has had sex with another man during the past 3 months." This policy replaces a previous one year deferral that was approved by the FDA on 21 December 2015, which itself replaced a previous lifetime ban on blood donations from MSM. The recommendations are nonbinding and generally do not establish legally enforceable responsibilities. Although the technically nonbinding recommendations may not be law, in practice they are regarded as if they are law. For example, the American Red Cross refers to the recommendation as a "federal requirement" that must be followed.
Females are also prohibited from donating for three months after having sex with an MSM. Prior to April 2020, this 3-month ban was the same 12-month period placed on MSMs. The argument used to follow these policies is that blood should be collected from a population that is at low risk for disease, since the tests are not perfect and human error may lead to infected units not being properly discarded, and these population groups would be considered a high risk. The policy was first put in place in 1983 by the FDA, which regulates blood donations to profit and non-profit organizations.
Donors of human cells and tissues other than organs, such as corneas or reproductive tissue like semen, are ineligible for five years after the most recent contact. With regard to corneal donations, the five-year deferral policy in the United States and the similar 12-month deferral policy in Canada have the effect of preventing thousands of corneal donations annually.
UNOS policies for organ donation allow for solid organs from MSM donors such as hearts, lungs, and kidneys to be used in transplant surgeries, though they require the hospital receiving the organ to be notified if the donor was an MSM within the past 5 years. The organs are generally used unless there is a clear positive test for a disease.
In 2006, the AABB, American Red Cross, and America's Blood Centers all supported a change from the current US policy of a lifetime deferral of MSM to one year since most recent contact. One model suggested that this change would result in one additional case of HIV transmitted by transfusion every 32.8 years. The AABB has suggested making this change since 1997. The FDA did not accept the proposal and had concerns about the data used to produce the model, citing that additional risk to recipients was not justified.
On 19 August 2009, the Assembly Judiciary Committee in California passed AJR13, the U.S. Blood Donor Nondiscrimination Resolution, calling upon the FDA to end the MSM blood ban.
In April 2010, the New York City Council passed a resolution calling on the U.S. Food and Drug Administration (FDA) to eliminate the ban stating "This ban was based on prejudice, a knee-jerk reaction, and misunderstandings about the HIV/AIDS disease. Given the constant need for blood, it does not make common sense to prohibit donations from an entire population."
On 1 June 2010, the Council of the District of Columbia passed a resolution calling on the FDA to "reverse the lifetime deferment of blood donations by men who have had sex with men since 1977 in favor of a policy that protects the safety and integrity of the blood supply that is based on an up-to-date scientific criteria."
In June 2013, the American Medical Association issued a statement calling on the FDA to change the policy, stating that "The lifetime ban on blood donation for men who have sex with men is discriminatory and not based on sound science."
In July 2013, the American Osteopathic Association approved a policy calling on the FDA to "end the indefinite deferment period for Men who have sex with Men (MSM)", and to "modify the exclusion criteria for MSM to be consistent with deferrals for those judged to be at an increased risk of infection."
On 14 December 2015, Jordan Moll-Vigrass, Congressmen Brian Higgins and the Pride Center of Western New York held a community rally in Buffalo, New York, to rally against the FDA policy that bans blood donations by gay and bisexual men. Moll-Vigrass, who is openly gay and had been in a committed relationship for four years, was refused as a blood donor after disclosing his sexual orientation during the questionnaire screening process. Outraged by the federal policy and disappointed by being refused as a blood donor, Moll-Vigrass started to advocate for change. "The government's unfounded policy is hurtful to the people being turned away solely based on sexual orientation and the millions of others who will be in need of a lifesaving blood donation," said Higgins. "Eligibility should be based on risk-based science rather than outdated, fear-based speculation."
On 21 December 2015, the U.S. Food and Drug Administration changed the policy by replacing the indefinite deferral with a 1-year deferral. The change was proposed the previous July.
On 27 May 2016, the U.S. Food and Drug Administration approved of a new blood donor history questionnaire for general use by blood establishments, which is compatible with the deferral for 12 months. Before this update, the approved questionnaires were compatible only with an indefinite deferral of blood donations from MSM.
As of December 2016, the American Red Cross reports that MSM may be eligible to donate blood if they did not have sex with another man in more than 12 months. The American Red Cross reports that, in January 2017, the organization began donor reinstatement of MSM who were previously deferred from donating, and who later became qualified to donate blood in accordance with the new donation deferral period of 12 months. The American Red Cross website specifies that this 12-month deferral does also apply to transgender men who have sex with men, but does not apply to transgender women who have sex with men.
Australia implemented a 12-month deferral in 1999; a comparison of confirmed HIV positive blood donations before and after the change did not see a statistically significant difference. The Australian Red Cross Blood Service pushed to have the deferral period lowered from twelve to six months, however it was rejected by the Therapeutic Goods Administration (TGA) in 2014. In April 2020 the TGA revised the deferral period for MSM down to three months. The revision requires approval of the federal, state and territory governments before it can go into effect.
Lifeblood's new 3-month deferral period rules went into effect on 31 January 2021. The spokesperson said they empathise with those who cannot give blood.
Blood services first and foremost must ensure that all blood received for donation is safe for transfusion purposes. This is achieved by screening potential donors for high risk behaviors through questionnaires and interviews before blood is taken, and subsequent laboratory testing on samples of donated blood.
Blood services commonly justify their bans against MSM due to the marginal increase in the risk for transfusion-transmitted HIV. Other groups with similar restrictions, or complete prohibition to donate blood, due to increased or possible risk for certain infectious diseases include intravenous drug users, recipients of animal organs or tissues, and those who have traveled or lived abroad in certain countries.
In the 1980s, when the HIV/AIDS epidemic outbreak occurred, there was a high prevalence of the disease on MSM and no reliable tests for the virus, which justified blanket bans on blood donations from high-risk groups.
These restrictions are similar to current restrictions on people with certain residence in the United Kingdom, France, or Saudi-Arabia during the height of the BSE ("mad cow disease") epidemic of 1980 through 1996, due to the absence of a test for its human form, variant Creutzfeldt–Jakob disease (vCJD).
In 1985, early tests using the ELISA method looked for antibodies, which are the immune system's response to the virus. However, there is a window period when using this method in which a person who has been infected with HIV is able to spread the disease but may test negative for the virus. This window period can be as long as three to six months, with an average of 22 days. Tests using the ELISA methods are often still used in developed countries because of their ease-of-use, as well as their fairly high sensitivity, which boasts 100% sensitivity. To cover the window period resultant from the use of these tests, donors are also screened for high risk behaviors, one of which is a history of same-sex sexual activity among male potential donors. Newer tests look for the virus itself, such as the p24 antigen test, which looks for a part of the virus on the surface of infected cells, and nucleic acid tests (NAT), which look for the genetic material of the virus in HIV-infected cells. With these tests, the window period is shorter, with an average duration of 12 days. Fourth generation, or combination, HIV tests can detect HIV infection in 99% of individuals by one and a half months after infection.
Risks are also associated with a non-MSM donors testing positive for HIV, which can have major implications as the donor's last donation could have been given within the window period for testing and could have entered the blood supply, potentially infecting blood product recipients. An incident in 2003 in New Zealand saw a non-MSM donor testing positive for HIV and subsequently all blood products made with the donor's last blood donation had to be recalled. This included NZ$4 million worth of Factor VIII, a blood clotting factor used to treat hemophiliacs which is manufactured from large pools of donated plasma, and subsequently led to a nationwide shortage of Factor VIII and the deferral of non-emergency surgery on hemophiliac patients, costing the health sector millions of dollars more. Screening out those at high risk of blood borne diseases, including MSM, reduces the potential frequency and impact of such incidents.
Objections to the restrictions, including those from the American Medical Association and the American Red Cross, are generally based on the idea that improvements in testing and other safeguards have reduced the risk from transfusion transmitted HIV to an acceptable level. Blood shortages are common, and advocates for change to the policies point out that excluding healthy donors only makes the problem worse. In 2018, approximately 10,000 donations were still urgently needed by 10 March to continue to meet patients' needs. However, Canadian Blood Services noted that the national inventory and days on hand of several blood groups remain at critically low levels. Less than four per cent of eligible donors give blood each year.
Corneal transplant surgery can cure blindness caused by corneal disease. However, there is a global shortage of corneal donations, severely limiting the availability of corneal transplants across most of the world. A 2016 study found that 12.7 million visually impaired people were in need of a corneal transplant, with only 1 cornea available for every 70 needed. Many countries have years-long waitlists for corneal transplant surgery due to the shortage of donated corneas. Even though there has never been a reported case of HIV transmission through corneal transplant surgery, and even though all donated corneas are screened for the presence of HIV through antibody or nucleic acid testing, many countries continue to ban MSM corneal donors.
In some European countries, high-risk sexual intercourses lead to a temporary ban, regardless of the sex of the partner. In fact, advocates for change in other countries note that the ban encompasses all same-sex sexual contact, even if the partner's HIV status is shown beyond doubt to be negative. Advocates for change point out that a promiscuous straight male is a higher-risk donor than a gay or bisexual man in a monogamous relationship, but the former will usually be allowed to donate blood. Furthermore, in some countries, other high-risk activities determine a temporary ban, such as sexual contact with anyone who has used needles to take drugs not prescribed by their doctor, whereas MSM donors are deferred indefinitely.
Activism regarding reform of MSM donor policies
In 2005, a student activist at the University of Vermont (UVM) filed a complaint with the university's Office of Affirmative Action, contending that American Red Cross blood drives on campus violated UVM's non-discrimination policy. The office recommended that the university no longer allow the Red Cross to conduct blood drives on campus, but the UVM administration rejected the recommendation, stating that it would not be in the interests of public health. Student and LGBT activism on the issue continued at UVM. In 2007, the UVM Student Government Associated voted down, by a 16–15 vote, a nonbinding resolution calling on the university to ban blood drives over the policy.
In 2008, San Jose State University President Don Kassing suspended all blood drives on campus on the ground that the MSM policy for blood donors violated the university's non-discrimination policy.
In 2008, a faculty member at Sonoma State University proposed a resolution in the faculty senate to ban blood drives on campus, The faculty senate passed the resolution by a 21–13 vote, clashing with the student senate, which passed a resolution earlier the same month noting the discrimination, but expressing support for the monthly blood drives because of their importance.
In 2013, a group of University of Michigan students favoring a loosening of the MSM blood-donation policy started a "Bleeding for Equality" initiative in which individuals ineligible to donate because of the policy would bring eligible individuals to donate on their behalf, so as to both promote blood donation and also demonstrate that the amount of additional blood that could potentially be collected if the policy changed. The Michigan Daily, the student newspaper of the University of Michigan, editorialized in favor of a loosening of the MSM blood donation policy.
On 27 July 2016, in the wake of the tragedy in Orlando on 12 June 2016, Blood is Blood hosted a blood drive on 27 July from 12 p.m. to 6 p.m. at the American Red Cross WNY Chapter Headquarters in Buffalo, New York. Jordan Moll-Vigrass who is known as "Jordan James" on television, Founder of Blood is Blood, and Matthew Crehan Higgins, executive director of the Pride Center of WNY, spoke at the event to raise awareness of existing archaic policies preventing many gay men from donating blood. There were reported expressions of frustration and disapproval by a number of gay and bisexual men who were forbidden to donate blood to victims, with LGBT activists across the country and a group of Democratic lawmakers urging the ban to be lifted. The FDA later said it had no plans of changing the regulation and will reevaluate its policies "as new scientific information becomes available".
In 2020, during the COVID-19 pandemic, gay Harvard physician Jack Turban told Vox and The Daily Show with Trevor Noah that after he recovered from COVID-19 infection that he wanted to donate plasma for clinical trials. He was unable to because of his sexual orientation. This resulted in 20 Attorneys General writing to The Department of Health and Human Services asking for the restrictions on MSM blood donations to be lifted.
In 2015, Welsh writer and poet RJ Arkhipov exhibited a poetry series written with his own blood as ink in protest of the MSM blood donor restrictions. His poem Inkwell discusses the shame and stigma surrounding "gay blood". An abecedarian poem, each line of Inkwell's five quatrains begins with letters from each of the blood groups, alternating between A, B, AB and O.
