Detransition is the cessation or reversal of a transgender identification or of gender transition, temporarily or permanently, through social, legal, and/or medical means. The term is distinct from the concept of 'regret', and the decision may be based on a shift in gender identity, or other reasons, such as health concerns, social or economic pressure, discrimination, stigma, political beliefs, or religious beliefs.

Some studies use the term retransition rather than detransition. Retransition is also commonly used to describe the resumption of transition or transgender identity following a detransition.

The estimated prevalence of detransition varies depending on definitions and methodology, with estimates ranging from 1% to 8%. A 2018 review on the outcomes of gender transition found a large majority of data showing positive outcomes, a few reports of neutral outcomes or null results, and no studies which reported that gender transition causes overall harm. Although some studies cite a range up to 8%, this combines 3% of survey respondents who had de-transitioned at the time of the survey, along with 5% who had temporarily done so in the past. Different methodological limitations afflict studies reporting low and high incidence.

Formal studies of detransition have been few in number, politically controversial, and inconsistent in the way they characterize the phenomenon. Professional interest in the phenomenon has been met with contention, and some scholars have argued there is censorship around the topic. Some ex-detransitioners regret detransitioning and choose to retransition later. Some organizations with ties to conversion therapy have used detransition narratives to push transphobic rhetoric and legislation.

Gender transition, often shortened to just transition, is the process of a transgender person changing their gender expression and/or sex characteristics to accord with their internal sense of gender identity. Methods of transition vary from person to person, but the process commonly involves social changes (such as clothing, personal name, and pronouns), legal changes (such as changes in legal name and legal gender), and medical/physical changes (such as hormone replacement therapy and gender-affirming surgery).

Detransition (sometimes called retransition) is the process of halting or reverting a transgender identification or gender transition. Like transition, detransition is a process rather than a single event, and methods of detransitioning vary and can involve social, legal, and physical changes to one's gender expression, social identity, identity documents. Desistance is a general term for any cessation, and it is commonly applied specifically to the cessation of transgender identity or gender dysphoria. Those who undertake detransition are known as detransitioners. Detransition is sometimes associated with transition regret, but regret and detransition do not always coincide.

The term detransition is controversial within the transgender community. According to Turban et al., this is because, as with the word transition, it carries an "incorrect implication that gender identity is contingent upon gender affirmation processes". The term has also been conflated with transition regret, and thereby become associated with movements that aim to restrict the access of transgender people to transition-related healthcare.

Formal studies of detransition have been few in number, of disputed quality and politically controversial. Frequency estimates for detransition and desistance vary greatly, with notable differences in terminology and methodology. Detransition is more common in the earlier stages of transition, particularly before surgeries.

The share of trans people who detransition is not known with certainty. Studies which give low estimates have been criticized for their "serious limitations", such as short follow-up, high or unclear rates of loss to follow-up, reliance on individuals returning to secondary care clinics reporting transition regret or seeking reversal procedures, (a study of 100 detransitioners found that only 24% of respondents informed their clinicians that they had detransitioned), errors, non-replicability, as well as other issues. Research suggesting higher rates of detransition also has flaws, however, meaning that detransition rates can be under-reported or over-reported.

A 2019 poster presentation examined the records of 3398 patients who attended a UK gender identity clinic between August 2016 and August 2017. Davies and colleagues searched for assessment reports with keywords related to regret or detransition. They identified 16 individuals (0.47%) who expressed regret or had detransitioned. Of those 16, 3 (0.09%) had detransitioned permanently. 10 (0.29%) had detransitioned temporarily, to later retransition. A 2019 clinical assessment found that 9.4% of patients with adolescent-emerging gender dysphoria either ceased wishing to pursue medical interventions or no longer felt that their gender identity was incongruent with their assigned sex at birth within an eighteen-month period. A 2021 study examining the case notes of 175 adults discharged from a UK gender identity clinic between September 2017 and August 2018 found that 12 (6.9%) met the researchers' criteria for detransitioning—that is, they returned to living as their assigned gender. Six individuals were found to have experiences that "overlap" with detransitioners, but were not counted as such for this study due to displaying "gender identity confusion" during treatment.

Those who undergo gender-affirming surgery have very low rates of detransition or transition regret. A 2005 Dutch study included 162 adults who received sex reassignment surgery, 126 of whom participated in follow-up assessments one to four years after surgery. Two individuals expressed regret at follow-up, only one of whom said that they would not transition again if given the opportunity. The remaining 124 out of 126 (98%) expressed no regrets about transitioning. A 2021 meta-analysis of 27 studies concluded that "there is an extremely low prevalence of regret in transgender patients after [gender-affirmation surgery]". In a January 2023 study of 1989 individuals who had undergone sex reassignment surgery, 6 individuals (0.3%) requested a reversal surgery or detransitioned.

Studies of transition regret or detransition in different populations have found different (average or median) elapsed times before these occurred: a 2018 study found 10 years and 10 months on average to regret (but not necessarily detransition) from start of hormonal therapy, and a 2014 study of those who had surgery found a median lag of 8 years before requesting a reversal of legal gender status. A 2021 UK study found evidence that supports detransitioning occurring on average 4–8 years after transitioning.

Informed consent and affirmation of self-diagnosis (both newer but increasingly employed models for transgender healthcare) have been criticized for failing to meet the needs of those who eventually detransition.

Criticisms have been made regarding the "persistence-desistance" dichotomy as ignoring reasons why a person's gender identity may desist outside of simply being cisgender in the first place. For example, an assertion of a cisgender identity may be treated with validity and as an invalidation of a previously stated transgender identity; however, an assertion of a transgender identity may only be treated with the same validity if it is held throughout one's life. An individual may repress or realize their identity at any point in their life for a variety of reasons; some individuals' gender identities are fluid and/or may change throughout their lifetime, and some individuals whose identities are non-binary are effectively excluded due to a study's assumption of a gender binary.

Reasons for detransitioning vary, and may include health-related concerns, finding that transition did not alleviate gender dysphoria, a negative social environment, and financial concerns.

The National Center for Transgender Equality conducted a survey which collected responses from individuals who identified as transgender at the time of the survey. The results published in the 2015 U.S. Transgender Survey found that 8% of respondents reported having ever detransitioned; 62% of that group reported transitioning again and were living as a gender other than the one assigned to them at birth at the time of the survey. About 36% reported having detransitioned due to pressure from parents, 33% because it was too difficult, 31% due to discrimination, 29% due to difficulty getting a job, 26% pressure from family members, 18% pressure from a spouse, and 17% due to pressure from an employer.

In a 2021 study of 2,242 individuals recruited via community outreach organizations who detransitioned and who continue to identify as transgender or gender diverse, the vast majority said detransition was in part due to external factors, such as pressure from family, sexual assault, and nonaffirming school environments; another highly cited factor was "it was just too hard for me." Motives for detransitioning commonly include financial barriers to transition, social rejection in transition, depression or suicidality due to transition, and discomfort with sexual characteristics developed during transition. Additional motives include concern for lack of data on long-term effects of hormone replacement therapy, concern for loss of fertility, complications from surgery, and changes in gender identity. Some people detransition on a temporary basis, in order to accomplish a particular aim, such as having biologically related children, or until barriers to transition have been resolved or removed. Transgender elders may also detransition out of concern for whether they can receive adequate or respectful care in later life.

A qualitative study comparing child desisters to persisters (those with persisting gender dysphoria) found that while persisters related their dysphoria primarily to a mismatch between their bodies and their identity, desisters' dysphoria was more likely to be, at least retroactively, related to a desire to fulfill the other gender role.

In August 2024, following recommendations in the Cass Review, NHS England announced plans for the first NHS service to support patients wishing to detransition. They said: "There is no defined clinical pathway in the NHS for individuals who are considering detransition. NHS England will establish a programme of work to explore the issues around a detransition pathway by October 2024."

While guidelines for transition have been published for decades—most notably in the Standards of Care (SOC) by the World Professional Association for Transgender Health (WPATH)—there are yet no legal, medical, or psychological protocols of comparable stature advising the processes of detransition. The WPATH SOC do not mention detransition, though thirty-seven WPATH surgeons have expressed a desire for detransition guidelines to be included, and former WPATH president and longtime chair of WPATH's Standards of Care revision team, Eli Coleman, has listed detransition among the topics that he would like to see included in the eighth edition.

Some researchers perceive there to be an atmosphere of censorship around studying the phenomenon. Various sides involved in the dispute over detransitioning say they have been harassed and have described each other as threats to transgender rights.

Controversy surrounding detransition within trans activism primarily arises from how the subject is framed as a subject of moral panic in mainstream media and right-wing politics. Detransition has attracted interest from both social conservatives on the political right and radical feminists on the political left. Activists on the right have been accused of using detransitioners' stories to further their work against trans rights. On the left, some radical feminists see detransitioners' experiences as further proof of patriarchal enforcement of gender roles and medicalized erasure of gays and lesbians. Other feminists have expressed disagreement with this opinion, referring to those who hold these beliefs as trans-exclusionary radical feminists (TERF). This attention has elicited in detransitioners mixed feelings of both exploitation and support.

In 2017, the Mazzoni Center's Philadelphia Trans Health Conference, which is an annual meeting of transgender people, advocates, and healthcare providers, canceled two panel discussions on detransition and alternate methods of working with gender dysphoria. The conference organizers said, "When a topic becomes controversial, such as this one has turned on social media, there is a duty to make sure that the debate does not get out of control at the conference itself. After several days of considerations and reviewing feedback, the planning committee voted that the workshops, while valid, cannot be presented at the conference as planned."

In 2017, Bath Spa University revoked permission for James Caspian, a Jungian psychotherapist who works with transgender people and is a trustee of the Beaumont Trust, to research regret of gender-reassignment procedures and pursuit of detransition. Caspian alleged the reason for the university's refusal was that it was "a potentially politically incorrect piece of research, [which] carries a risk to the university. Attacks on social media may not be confined to the researcher, but may involve the university. The posting of unpleasant material on blogs or social media may be detrimental to the reputation of the university." The university stated that Caspian's proposal "was not refused because of the subject matter, but rather because of his proposed methodological approach. The university was not satisfied this approach would guarantee the anonymity of his participants or the confidentiality of the data." In May 2017, he took the matter to the High Court, which concluded his application for a judicial review was "totally without merit". The outcome was also considered by the Office of the Independent Adjudicator for Higher Education, who determined the university's conclusion was reasonable. Caspian appealed to the High Court for judicial review again in 2019; the judge ruled against him, saying, "I entirely accept that there are important issues of freedom of expression. I just do not accept that, on the facts of this particular case, there is an arguable case made out," and adding that the application was too late. Caspian claimed that he was "refused permission for a Judicial Review on points of procedure" and that the judge "was clearly sympathetic to the case but felt that his hands were tied by legal procedure;" in 2021, he appealed to the European Court of Human Rights.

In 2023, Do No Harm (a medical and policy advocacy group in the United States) published their Detransitioner Bill Of Rights. The document advocates for "Informed consent", "Effective care", "Insurance coverage", "Legal restoration", and "Justice" for detransitioners.

Many ex-gay and Christian Right affiliated organizations also promote programs aiming to discourage transition, promote reversal or desistence of transition, and to change individuals' gender identities. A key characteristic of these organizations are the construction of "transgenderism" as a sin against God or the natural order. In the 1970s, Exodus International platformed Perry Desmond, an "ex-transsexual" who evangelized throughout the US and supported Anita Bryant's Save Our Children campaign. Another prominent characteristic is ex-transgender testimonials, which depict "the transgender lifestyle" as destructive as opposed to contemplation of God and encourage other transgender people to join them. These organizations portray "gender ideology" and "transgender ideology" as a social contagion threatening to the natural order.

Ky Schevers, an "ex-detransitioner" whose detransition was prominently profiled by Katie Herzog and The Outline, spoke about her experiences in a community of radical feminist detransitioned women, drawing parallels to the ex-gay movement and conversion therapy. Parallels drawn include suppressing rather than addressing or removing the underlying dysphoria, stating that not only their gender dysphoria but everyone's dysphoria was a result of internalized sexism and trauma, and language from the twelve-step program being used to describe the desire to transition.

Schevers noted that during the Bell v Tavistock ruling, her lawyer had connections to the right-wing and anti-LGBT-rights organization the Alliance Defending Freedom, which she described as pushing most of the anti-trans bills in the United States. Schevers later created Health Liberation Now! alongside Lee Leveille, who'd also previously been involved in detransition communities that were transphobic, to "give voice to folks who have complicated experiences with transition or detransition, retransition and shifting senses of self that goes beyond a lot of the TERFy areas that people are inevitably getting funnelled into". The group has reported on conversion therapy practices and maintains resources to help identify relationships between clinical conversion therapists and astroturfed campaigns led by anti-trans groups.

In 2021, legislatures in 22 states in the United States introduced bills that would criminalize the provision of gender-affirming care to transgender minors, forcibly detransitioning those who are unable to or refuse to leave the state. By the end of February 2022, the number had risen to 29. Supporters of these bills often cite concerns about detransition and desistance and claim they wish to protect children. Scientific evidence suggests these bills will cause harm to transgender children as gender-affirming care is often necessary and access to it has consistently shown a positive relationship with mental well-being, and an inability to access gender-affirming care can cause gender dysphoria, which can commonly lead to anxiety, depression and even suicide in transgender children and teens.

The American Medical Association, American Academy of Pediatrics, and American Psychological Association have spoken out against the bills and defended the right of minors to transition. In a letter to the National Governors Association, the American Medical Association warned that anti-trans healthcare bans will lead to greater rates of depression and suicide for transgender youth and described bills banning gender-affirming care as "a dangerous intrusion into the practice of medicine". Pediatricians testifying against the bills have said they are based on myths and misconceptions about transgender healthcare. A medical report published by Yale in response to bans on gender-affirming care argued that the bans were no more ethical than a prohibition on healthcare for any other life-threatening medical condition. The president of World Professional Association of Transgender Health wrote an opinion article in the New York Times stating her view that these laws constituted an effort to "rid the world of transgender people." Similar sentiments were expressed in a WPATH public communique: "Anti-transgender health care legislation is not about protections for children but about eliminating transgender persons on a micro and macro scale."

In 2021, the Arkansas legislature passed House Bill 1570, prohibiting transgender youth from receiving gender-affirming health care of any kind. The ACLU challenged the bill, leading a federal judge to issue a temporary injunction, protecting transgender youth in the state from being detransitioned against their will.

In April 2022, Alabama Senate Bill 184 was approved. The bill prevents doctors from prescribing puberty blockers or hormone therapy for transgender youth under a threat of up to 10 years in prison, forcibly detransitioning youth in the state, and mandates that school staff out students to their parents.

On August 5, 2022, the Florida Board of Medicine voted to consider guidelines proposed by the state's surgeon general, starting the process of denying transgender youth in Florida gender-affirming care. On October 28, 2022, Florida's Board of Medicine passed a motion to ban all gender-affirming healthcare for minors, including puberty blockers, hormones, and surgeries. The motion mandates all transgender youth to detransition until they turn 18. At one point during the hearing, in response to one protester yelling that trans children would be harmed as a result, board member Dr. Zachariah P. Zachariah answered "That's okay", before forcing a vote ahead. Some who'd been at the meeting were reported as saying that the board had put all the speakers in favor of the ban, many of whom were from outside of the state or outside of the country, first in line to speak, before cutting off public comment once they ran out and pro-trans Floridians began to take the podium. The Florida Department of Health released official state guidance that transgender children should not be allowed to wear clothes or use names or pronouns aligning with their gender identity.

In Spring 2021, the Center for Christian Virtue proposed Ohio House Bill 454, known as the "Save Adolescents From Experimentation (SAFE) Act" in Ohio. The bill was introduced by state representative Gary Click in 2022 without consulting any transgender people beforehand and would forcibly detransition all transgender minors in the state. The bill would also require counselors, teachers, and all other staff at public and private schools to out transgender youth to their parents. Click stated he believes children are being "groomed" into thinking that they are trans. In February 2023 Click introduced House Bill 68, which according to Planned Parenthood of Ohio "would ban gender-affirming care for transgender and non-binary youth ─ regardless of parental consent, wishes of the patient, diagnosis, or previous care-plan".

In August 2022, Marjorie Taylor Greene of Georgia introduced the "Protect Children's Innocence Act" that would make providing gender-affirming care to transgender minors a felony punishable by up to 25 years in prison and prohibit the use of federal funds for gender-affirming care, including in Affordable Care Act plans. The bill would also prohibit higher education institutions from providing instruction on gender-affirming care and bar doctors who have provided gender-affirming care to minors from receiving visas or being admitted to the United States.

In 2023, dozens of bills in over 10 U.S. States have been proposed which would ban minors from receiving gender-affirming care.

Many Republican legislators across the United States are increasingly proposing legislation that would restrict gender-affirming care for adults or make such treatments harder to access. However, no states have succeeded at outright banning gender-affirming care for adults in a way similar to what is being done with minors. Efforts to restrict adults' access to healthcare relies heavily on claims from self-described "gender-critical" organizations such as Genspect that young people should not be recognized as adults until they turn 25.

As of January 2024, seven US states limit access to gender-affirming care for adults in some way without banning it, such as allowing private health plans, Medicaid, and correctional facilities to exclude all coverage for gender-affirming care, prohibiting the use of federal funds for gender-affirming care or requiring informed consent practices beyond those typically required in medical practice.

In January 2024, several US Republican legislators expressed their desire to ban gender-affirming healthcare altogether saying their 'endgame' was to ban it completely for people of all ages.

On June 2, 2022, Florida Governor Ron DeSantis announced a plan to end Medicaid coverage for transgender adults, making them the first U.S. state to target hormones and transition coverage for adults and removing care for approximately 9,000 adults.

In Missouri in 2022, state legislators weighed extending a youth healthcare ban to adults under 25. The bill died in the committee.

In 2023, the state of Oklahoma introduced the "Millstone act" which would prohibit adults up to 25 from receiving gender-affirming care and prohibit Medicaid coverage for "gender transition procedures" for those under 26. The bill ultimately did not pass.

On March 12, 2023, a Saudi trans woman named Eden Knight died by suicide after being forcefully detransitioned. Knight wrote in a suicide note that her parents had hired an American private intelligence firm and a Saudi lawyer to relocate and forcibly socially and medically detransition her. After becoming dependent on the lawyer for food and shelter and fearing he would report her to U.S. immigration authorities, Knight wrote that she returned to her parents in Saudi Arabia. She secretly continued feminizing hormone replacement therapy, but after being found out twice she died by suicide.

In many prisons within the US, both state and federal, trans prisoners are often forcibly detransitioned.

Forced detransition has been described as a form of transgender genocide. This is primarily due to the assertion that forced detransition fits multiple criteria to be described as an act of genocide under the United Nations definition of such. Laws banning gender affirming care and/or directly forcing those receiving it to detransition have been described as fitting two acts defined as acts of genocide by the UN - "causing serious bodily or mental harm to members of the group" and "deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part", and laws allowing child protective services to pursue child abuse claims against the parents of children receiving gender-affirming care and remove said children have been described as fitting another defined act of genocide, that of "forcibly transferring children of the group to another group".
