Overview

Prepubertal social transition means a child under about 11 starts living as the opposite sex: a new name, new pronouns, different clothes and hair, and being treated as a boy or girl at school and in the family. No medication is involved. At this age the child cannot arrange any of this alone, so it is always a decision made, or at least carried out, by adults.

The parent page on social transition covers the general debate. This page goes deeper into the youngest group. It looks at how small children understand sex, the research from the TransYouth Project (a long-running US study of socially transitioned children) and the main criticisms of it, the Dutch finding that social transition was linked to persistence, and the warning from Kenneth Zucker, the psychologist who led Toronto's child gender clinic for decades, that early transition may cause the persistence it is meant to respond to. It also covers the role of parents, the link between gender non-conformity and later homosexuality, and what people who were socially transitioned as children say now.

How young children understand sex

Gender constancy

In 1966 the psychologist Lawrence Kohlberg proposed that children understand sex in three stages. First they learn to label themselves and others as boys or girls (around ages 2 to 3). Then they learn that this label stays the same over time (gender stability). Last, at around ages 5 to 7, they understand that a person's sex does not change when their clothes, hair or activities change. Kohlberg called this gender constancy.

Later research has refined the details but kept the basic picture. A classic study of 2- to 5-year-olds found that children who had reached gender constancy paid more attention to same-sex role models (Slaby & Frey 1975). A study of 94 children aged 3 to 7 found that knowledge of stereotypes, and how rigidly children held those stereotypes, rose sharply between ages 3 and 5 (Ruble et al. 2007). Another study found that many 4- to 6-year-olds answered constancy questions as though they were about a "pretend" situation rather than a real one (Martin & Halverson 1983).

Why this matters for social transition

This research matters because of what a young child means by "I am a boy". For a 4-year-old, "boy" is often defined by visible things: short hair, trousers, rough play, the toys boys have. The same child may not yet know that being a boy or a girl is about the body and cannot be changed. So a young girl who says she is a boy may be telling adults something true and important, such as "I like what boys like" or "I don't want to wear dresses". But she may not be saying what an adult would mean by the same words.

Some desisters recall exactly this kind of thinking:

When I was a kid like six years old I would refer to myself as male...because I liked the sound of 'he/him' and 'boy' better than 'she/her' and 'girl'. I literally just thought it sounded nicer on my ears and that we just got to choose which one we called ourselves, like it was optional or something. —NoctaeBride, r/detrans commenter

studies have shown over and over again that children have distorted and black and white thinking about gender. they think a barbie doll has changed sex when you put a suit on her. —portaux, desisted

A desisted woman describes suggesting that a doctor simply ask her 5-year-old daughter what being a boy meant to her:

The little girl said she liked science, but one of her kindergarten classmates told her liking science was for boys, so she wanted to be a boy so she could like science. … her daughter happily dropped the subject of being a boy. —quendergestion, desisted female

What social transition teaches a child about sex

The TransYouth Project (a US study led by psychologist Kristina Olson that has followed socially transitioned children since 2013, described in its own section below) tested gender constancy in socially transitioned preschoolers. Thirty-six transgender 3- to 5-year-olds did not differ from control children on gender preferences and behaviour. However, they were less likely than controls to believe that their gender at birth matched their current gender. Both they and their siblings were also less likely than controls to believe that other people's gender is stable (Fast & Olson 2018).

The authors read this as a sign of the children's real experience. A more cautious reading is that the family environment was teaching them something. A child who has been told "you used to be a girl and now you are a boy", and whose siblings hear the same, learns that sex can change. That belief is untrue. A social transition at age 4 or 5 happens exactly when children are working out whether sex is permanent. So it may affect how the child understands their own body during the years before puberty, as well as reflecting how the child already felt. For the wider role of stereotypes, see gender stereotypes.

From watchful waiting to early transition

Until the 2010s, most clinics did not recommend full social transition before puberty. The Amsterdam clinic that created the original Dutch protocol advised families to support the child but to wait. In a 2011 letter, Thomas Steensma and Peggy Cohen-Kettenis reported that complete social transition at first visit was still rare in Amsterdam, but rising: 1.7% of children referred before 2000, and 3.3% between 2000 and 2004. They described two girls who had lived as boys in primary school, then struggled for a long time to return to living as girls when their dysphoria faded, partly out of fear of being teased. They concluded that waiting until early adolescence "may be less serious than having to make a social transition twice" (Steensma & Cohen-Kettenis 2011, as quoted in Ashley 2019).

In the United States a different model took hold. Under gender-affirming care, a child's stated identity is accepted and acted on, often starting with a full social transition. The Cass Review noted that this model began in the US and then spread to other countries (as summarised by the Society for Evidence-Based Gender Medicine, SEGM 2024). A commonly used rule of thumb was that a child who is "insistent, persistent and consistent" should be supported to transition. The desistance page explains why that phrase has no agreed definition.

The TransYouth Project

Most research on socially transitioned young children comes from one US study: the TransYouth Project (TYP), led by Kristina Olson. To join, a child had to be aged 3 to 12 and to have already made a complete binary social transition, including a change of pronouns.

The mental health studies

The first major TYP paper studied 73 socially transitioned children aged 3 to 12. They showed no raised levels of depression and only slightly raised anxiety compared with population averages, based on what their parents reported (Olson et al. 2016). A follow-up using the children's own reports found similar results (Durwood et al. 2017). These studies were widely reported as evidence that early social transition protects children's mental health.

They cannot show that. There was no measure of the children's mental health before they transitioned, and no comparison group of similar dysphoric children who did not transition. The families were also unusual, as the researchers themselves acknowledged. Children were recruited through support groups, conferences, clinicians and media coverage, and the sample was "predominantly White, of higher socioeconomic status, and higher parental educational status" than average (Olson & Gülgöz 2018). Healthy children from well-off, supportive families would be expected to do well whatever the intervention.

Who goes on to transition?

A later TYP study followed 85 gender-non-conforming children who had not transitioned. About two years later, 36 had socially transitioned. Those who later transitioned had shown stronger cross-sex identification and preferences at the start (Rae et al. 2019). Supporters of early transition use this to argue that social transition reflects a child's existing identity rather than creating it.

The finding is real, but it does not settle the question. It shows that the more strongly gender-non-conforming children were more likely to be transitioned by their parents. It does not show what would have happened to those same children if they had not been. In the older Toronto and Amsterdam studies, strong cross-sex behaviour also predicted persistence, yet most of those children still desisted (Singh et al. 2021). A related TYP study found that most parents of gender-non-conforming children who had not transitioned had already discussed transition with them (Olson et al. 2019). That shows how present the idea already was in these families.

The five-year persistence study

The best-known TYP paper followed 317 children who had socially transitioned at an average age of 6.5 (Olson et al. 2022). About five years later, 94% identified as binary transgender, 3.5% as non-binary and 2.5% as their own sex. 7.3% had "retransitioned" at least once. The parent page on social transition summarises the main criticisms. Three details matter most for young children:

• Transition before 6 was less stable. Later identification with their own sex was more common among children who transitioned before age 6, and those changes usually happened before age 10 (Olson et al. 2022). Reported figures were 5.6% for children who transitioned before 6, compared with 0.5% for those who transitioned at 6 or older (MedPage Today 2022).
• Follow-up stopped before the key years. The older studies found that desistance usually happened around ages 10 to 13, during puberty and first sexual attraction (see desistance). By the end of follow-up, many TYP children had not yet gone through those years. Puberty was also being blocked for a significant share of them.
• The outcome measured was identity, not wellbeing. The study measured whether children still identified as trans. It did not measure whether they were thriving, and it did not count the medical steps that followed as a cost.

Show details: the main criticisms of the TransYouth Project

Issue	Why it matters
Sample	Families recruited through support groups, conferences and media. Higher income and education than average, mostly White. Every family was supportive enough to carry out a full transition.
Selection	Social transition was an entry requirement, so there was no comparison group of similar children who did not transition. The study cannot tell cause from selection.
Follow-up	About five years, ending around age 11 to 12 on average. This is before or during the period when desistance usually happened in earlier studies.
Outcome	Persistence of a trans identity was treated as the result. In a group where puberty blockers and hormones were starting, persistence also means a medical pathway.
Who reports	The early mental health findings relied heavily on parents. These were parents who had made, and were publicly committed to, the transition decision.

Social transition and persistence

The Amsterdam finding

The Dutch follow-up of 127 children referred before age 12 found that 47 still had gender dysphoria in adolescence. Several factors predicted persistence, including the intensity of dysphoria and age at referral. Having made a childhood social role transition was among the strongest, especially for natal boys (Steensma et al. 2013). In the authors' analysis, social transition accounted for the largest share of unique variation in persistence, about 12%, compared with 6% to 7% for each other predictor (Steensma et al. 2013, as quoted by Transgender Trend).

Zucker's warning: "iatrogenic" persistence

Kenneth Zucker, who led the Toronto child gender clinic for decades, argued that social transition of a young child is not a neutral response but a psychological treatment in its own right. He predicted:

Gender social transition of prepubertal children will increase dramatically the rate of gender dysphoria persistence when compared to follow-up studies of children with gender dysphoria who did not receive this type of psychosocial intervention and, oddly enough, might be characterized as iatrogenic. — (Zucker 2020)

Iatrogenic means caused by treatment. Zucker's point is that if a child lives as the other sex through all the years when most dysphoric children used to desist, the treatment may produce the persistence. That persistence is then used as proof that the child was trans all along. He adds that the "likely consequence" is lifelong medical treatment (Zucker 2020).

The counter-argument

Trans-affirming writers argue that social transition is a marker of more intense or more genuine dysphoria, not a cause of persistence (Jones 2022). The TYP prediction study is often cited for the same point (Rae et al. 2019).

Both explanations fit the available data, and the two are not mutually exclusive. Children with stronger cross-sex feelings may be more likely to be transitioned, and transition may then strengthen and fix those feelings. Separating the two would need a long-term comparison of similar children who did and did not transition, followed into adulthood. No such study exists. Given that gap, the Cass Review's view was that the decision should be treated as an intervention with possibly lasting effects (Cass 2024).

What the reviews concluded

The University of York's systematic review for the Cass Review found eight studies of social transition in children. They "consistently reported no difference in mental health outcomes" between children who had socially transitioned and those who had not. The studies were mostly low quality and cross-sectional (Hall et al. 2024). In other words, the claim that early transition protects mental health was not supported. Neither was any clear claim of harm. The evidence was simply too weak.

The Cass Review's final report added that children who socially transitioned earlier, or before reaching a clinic, were more likely to go on to a medical pathway (Cass 2024). Its fourth recommendation applies directly to young children:

When families/carers are making decisions about social transition of pre-pubertal children, services should ensure that they can be seen as early as possible by a clinical professional with relevant experience. — Cass Review recommendation 4, as published by (NHS England 2024)

NHS England's interim service specification adopted "a more cautious approach to assessment, diagnosis and intervention, including social transition particularly for younger children", with a primary approach that is "psychosocial and psychological rather than medical" (NHS England 2024). For the wider picture of these reviews, see evidence reviews.

The role of parents

A 5-year-old cannot change their own name at school, buy a new wardrobe or tell the extended family. Parents do these things. TYP researchers describe early social transition as "a process that children are leading", based on what parents report (Olson et al. 2019). Adults who were these children often describe something more mixed: a child's wish, shaped by stereotypes and by adults' reactions, and then acted on by adults.

I was a four year old who wanted to be a boy too. It shouldn't and didn't mean anything and my parents only went along with it when I would refuse to respond to everything except my male cousin's name. … But I'm a detrans woman now missing body parts and I wish my parents would have told me it's okay to me a gender non conforming woman. —Ok-Cress-436, detrans female

Several detransitioners describe how parents' own attitudes to sex roles shaped a childhood wish to be the other sex. Some describe a parent forcing them to be girly or manly. Others describe a parent who seemed to prefer the other sex:

one of my clearest memories from early, early childhood was telling my parents i wished i was a girl. it took many years for it to click that i only said that after being told i couldn’t wear certain things because i was a boy. —bradx220, detrans male

In my case that was combined with my mum’s gender envy because she envied mums of boys because ‘sons always love their mother’ and ‘the relationship between mothers and sons is special’. I don’t think she was even aware she was making me feel bad about being a girl - she just did. —Luck_Unlucky, desisted

Pressure does not only come from progressive parents. One commenter describes conservative parents who seemed to prefer a trans child to a gay one:

My take is that by going trans, they would no longer have a GNC / gay child to embarrass them. —Liminal_exp, socially transitioned, regrets transition

Many people who were transitioned young say their parents acted out of love and fear, often after being told that refusing could lead to suicide (see suicide and transition):

Your parents were probably told at some point, either by a doctor or by the Internet, that you'd likely kill yourself if they didn't immediately enable you to do this. —OkHurry8168, detrans male

Among ~3,100 r/detrans stories analysed by detrans.ai, parental or medical pressure was judged to have contributed to transition in about 8% (n = 3,094) (detrans.ai stats). Most people in that cohort transitioned as teenagers or adults, so this figure says little about early childhood transitions specifically. For practical guidance aimed at families, see schools and parents.

Gender non-conforming children and later homosexuality

The strongest finding in the childhood follow-up studies is about sexual orientation, not gender. In the largest study, of 139 boys referred to the Toronto clinic, 87.8% were no longer dysphoric at follow-up. Nearly two-thirds of those with data were attracted to males or to both sexes in fantasy (Singh et al. 2021). The desistance page sets out the full set of studies.

This is why many gay and lesbian critics see early social transition as a particular risk for gender-non-conforming children who would otherwise grow up gay. A feminine boy is usually just a feminine boy, and a boyish girl is usually just a boyish girl. Many such children grow up gay or lesbian, though not all. Desisters describe how a childhood wish to be the other sex was tied up with sexuality before they had words for it:

Same here, I wanted to be a girl because I thought I needed to be a girl to be feminine, to be free of masculine social expectations, to have a loving relationship with another man —HeForeverBleeds, desisted male

Like 20 years ago most parents knew sons like this would likely grow up to be feminine gay men. —nomad_andre, desisted male

If a child is socially transitioned at 5 and puberty is blocked at 11, they may never get the chance to find out whether they would have grown up to be a gay man or a lesbian. See internalised homophobia and gender non-conformity without labels.

What people transitioned as children say

What detransitioners report

Children who were socially transitioned around 2010 to 2017 are only now reaching adulthood. Their first-hand accounts are starting to appear, and they are some of the most striking on r/detrans. One woman, who was socially transitioned at 7, wrote at 18:

Everyone called me by my new name, everyone saw me as a boy etc. It all happend very fast … I dont even remember what it was like living as a girl … As a girl i was just boyish and when i heard about trans people i thought “hey Yea that must be me” … Why did my parents let me do that at such a young age??? —LateInvestment1093, detrans female

When asked in the same thread what followed, she replied:

Started blockers at age 12 and T at age 15 —LateInvestment1093, detrans female

That sequence is the one Zucker and the Cass Review warned about: social transition in early childhood, then puberty blockers at the start of puberty, then cross-sex hormones in mid-adolescence. A young man who started hormones at 11 describes the anger that can follow, even with parents who were kind:

I feel like they were supposed to protect me from all of this, you know? —will_ofgod, detrans male

Others were socially transitioned as children but stopped before any medical step. They describe growing out of it, or realising that their distress had a different cause:

I socially transitioned to male in elementary/middle school and desisted in highschool when I realized my dysphoria wasn’t about my gender, just about the fact that I wish I had a penis. —Softandpainful, desisted female

I socially transitioned as much as could, but was never allowed any kind of medical transition. I didn't kill myself like the trans narrative would claim, but I did eventually grow out of it. —Anonym00se01, desisted female

A recurring theme in these accounts is lost memory and lost childhood: not remembering life as one's own sex, and having no childhood memories to return to. For the experience of changing name and pronouns back, see names and pronouns and social and practical detransition. Video accounts, including "I Was a Trans Kid So You Don't Have to Be", are in the video archive.

What trans people describe

Many trans adults say they knew from early childhood, and some wish they had been allowed to transition then:

I sort of always knew. I didn't have the words but when I was maybe 5 I knew I wasn't mean to be a boy, I sort of hoped or assumed that I'd just grow up to be a woman. —N-y-s-s-a, trans woman (MTF)

I wonder a lot how different and self-secure I would be if I was allowed to have a boy’s haircut, a boy’s name, a binder and didn’t have people continually pushing that I should switch to girlie things —LovelyLillSparrow, trans man (FTM)

A highly upvoted answer to an aunt or uncle asking whether 6 is too young puts the affirming case clearly. It also shows how social transition is expected to lead on to medical steps:

For kids so young, transition usually amounts to new clothes, haircut, and a new name at most … If she socially transitions now and remains enthusiastic about being a girl until puberty starts, medical intervention would probably be wise to consider —MyHouz, trans woman (MTF)

These experiences are real, and some trans adults describe early distress that never went away. But looking back from adulthood cannot show which children would have stayed trans and which would have desisted. Adults who desisted, who were also sure as small children, are much less visible in these discussions.

What the /stats data show

detrans.ai's statistics come from about 3,100 r/detrans stories. An AI assembled each user's posts into a timeline, and only users who clearly confirmed detransition or desistance are included. It is a large but self-selected sample, AI extraction can contain errors, and the figures are not detransition rates.

(detrans.ai stats)

Two things stand out. First, a sizeable minority of these detransitioners and desisters date their dysphoria to early childhood. So childhood onset by itself does not show that a person will stay trans. Second, almost none of them transitioned before age 10. This cohort mostly transitioned as teenagers or adults, so these data cannot show how children transitioned at 4 to 7 will fare. That group is only just reaching the age at which people tend to post on r/detrans.

Known risks and unknowns

Social transition involves no drugs. But the Cass Review treats it as an intervention, so the possible harms deserve the same plain listing as any other treatment.

Unknowns. No study has compared similar young children who did and did not socially transition and followed them into adulthood. Nobody knows how many of the TYP children will desist after puberty or in their twenties, how many will regret any medical steps, or how their sexual orientation will develop. The effects on siblings, on children's understanding of sex, and on children who later need to re-transition at school have barely been studied. Until better evidence exists, it is not known whether early social transition helps, harms or makes no difference to children's long-term outcomes.

Summary

• Young children often understand "boy" and "girl" through clothes, toys and play. Many do not yet grasp that sex cannot change.
• Before the 2010s, clinics usually advised against full social transition before puberty, and most dysphoric children desisted. Many grew up gay or lesbian.
• The TransYouth Project found high persistence after early social transition, but it had no comparison group, recruited from supportive, well-off families, and stopped following children around puberty.
• The Amsterdam data linked childhood social transition to persistence. Zucker warned this persistence may be partly caused by the transition itself. No study can yet tell cause from selection.
• The York review found no good evidence of mental health benefit. The Cass Review calls social transition an active intervention and wants clinicians involved early for prepubertal children.
• Some people transitioned as small children now describe a path through blockers and hormones that they regret. Some trans adults wish they had transitioned younger.

If you are a parent, or someone who was transitioned as a child, the support directory lists gender-exploratory therapists and detransition support groups. Research is collected in the study archive.
