Overview

Non-binary (also "nonbinary" or "enby") is an identity label for people who say their gender is neither exclusively man nor exclusively woman. It sits under a wider umbrella that includes genderqueer (an older, more political term), genderfluid (a gender said to change over time), agender (having no gender), demigirl/demiboy (partly identifying with one gender), and hundreds of newer coinages such as xenogenders (genders described through animals, objects or concepts) and neopronouns (invented pronouns such as ze/zir or noun-based forms).

Every human being is still one of two sexes. Non-binary labels do not describe a third sex or a body type. They describe how a person relates to the social expectations attached to their sex, which makes them a question about gender stereotypes, not biology. And turning that relationship into an identity does not free anyone from the stereotypes. It makes them the definition of what a man or a woman is.

This page sets out why non-binary identities reinforce the stereotypes they claim to escape, and what detransitioners and desisters (people who stopped identifying as trans before medically transitioning) who once identified as non-binary say about it. It then covers where the labels came from, how quickly they spread, how non-binary people are now being treated medically and the evidence gap behind that treatment, and how non-binary people describe themselves.

How non-binary identities reinforce stereotypes

Start with three ideas most people accept:

1. Sex is a material category: male or female, set by the reproductive system a body is organised around.
2. Gender roles are social expectations attached to each sex: how men and women "should" dress, behave, feel and what they "should" like.
3. Those roles are restrictive, unfair and often harmful. Feminism and gay liberation spent decades arguing that a woman who is assertive, short-haired and uninterested in make-up is still fully a woman, and that a gentle, artistic man is still fully a man.

Non-binary identity adds a fourth idea: some people are neither men nor women, because they do not match the masculine or feminine package. Once that step is taken, the stereotype is no longer a social rule that a person can break. It becomes the definition of the category. If not fitting "woman" makes you something other than a woman, then "woman" must mean the feminine package after all. The problem is moved from the stereotype onto the person.

One detrans male put it this way, describing a realisation he had in 2002, before the label was widespread:

The epiphany of my detransition was that masculine and feminine were not an intangible concept of 'gender identity', they were merely personality traits that were common but not exclusive to one sex or the other (basically what feminism has been teaching for decades)… Non binary flies in the face of all that because it's attributing characteristics and personal expression to gender identity… —cagedbunny83, detrans male

The "everyone is non-binary" problem

Nobody fully matches the masculine or feminine stereotype. If the test for being non-binary is having a mix of masculine and feminine traits, almost everyone passes it. As one detrans female wrote, "That describes literally 99% of the population" (ButchPeace274, detrans female). That leaves two options. Either the label means nothing, because it applies to everyone. Or it marks out the people who feel their mix of traits is too far from the stereotype to count, and that judgement depends on taking the stereotype seriously as a measure.

A desisted male who considered the label reached the same conclusion:

I was just reaffirming the idea that men are this and women are that. For all the talk about breaking gender roles, people seem very happy to put themselves into those strictly defined boxes… If I called myself non-binary or GNC, I would just be ratifying gender roles. —Gyrofennec, desisted

"It's an inner sense, not a stereotype"

Many non-binary people say their identity has nothing to do with stereotypes: it is an inner sense of self, independent of clothes, interests or appearance. Some trans commenters make this point sharply. One trans man said androgyny is "a form of gender expression, not a gender identity" (mrselffdestruct, trans man (FTM)). A non-binary commenter said they would be happy to be "indistinguishable from a run of the mill standard issue cis dude" (commiepissbabe, non-binary (r/ftm)).

But that leaves the identity without content. If it is not about the body, which is still male or female, and not about expression or stereotypes, what remains is a felt inner gender that cannot be observed, measured or checked, and nothing distinguishes that feeling from a reaction to social expectations. Labels like "genderfluid", which depend on feelings that change from day to day, point the same way: a trait that shifts with mood and context is a response to circumstances, not a fixed part of who someone is. This is the same difficulty raised by "born in the wrong body" claims, with even less external anchoring.

The sex asymmetry

The female skew in the prevalence figures suggests what the label is often responding to. Several detransitioners describe non-binary identity as a way to manage the costs of being female, such as objectification, sexual attention and lower status, by opting out of the category instead of challenging how it is treated:

The concept is used by many women to manage the psychological distress of feeling vulnerable due to being a woman. This is especially common in younger years when men pay us the most attention and there's a lot of pressure on us. —furbysaysburnthings, detrans female

That is an understandable coping strategy, and it is not a moral failing. But it leaves sexism intact. It can also depend on a view of womanhood as something to escape, which is a form of internalised misogyny. The male version, where a man feels inferior for being gentle, and escapes being seen as a feminine man by becoming "neither", is described below.

What gets lost

When gender nonconformity is turned into an identity, the old ordinary categories shrink. Tomboys, butch lesbians, feminine men and androgynous people of both sexes used to be understood as ordinary members of their sex. Commenters describe being re-labelled whenever they refuse a stereotype:

As a "GNC" woman, the amount of times I've been told I'm actually trans is staggering. I tell them I don't believe in gender and I get declared agender. —IllegallyBored, detrans female

The alternative is not to force anyone into femininity or masculinity. It is the reverse: gender nonconformity without labels, where a person can be any mix of traits and still be simply a woman or a man.

What former non-binary detransitioners and desisters describe

These accounts come from a self-selected online community (r/detrans) and cannot show how common any pattern is. Some themes come up repeatedly.

"Not a good enough woman", then a new box

The most common theme is that the identity grew out of feeling like a failure at the stereotype:

…my identification with NB was because I didn't think I was a 'good enough' woman. That's an incredibly harmful message to send to young women. —subtropicalyland, questioning own gender identity

That's literally why I thought I might be trans or non-binary, because i was "failing" to be a woman in my mind by not conforming to stereotypes —crazycatnerd, desisted female

Several describe the identity as freeing at first, then more restrictive than womanhood had been, because they now had to perform non-binary-ness so others could see it:

…at first identifying as nonbinary felt really freeing, because I was already kinda gnc... but over time it became just another box I tried to fit myself into… I couldn't really wear or like some of the stuff I actually did like, because I felt it was "too girly". —Grey-Skies-Silflays, detrans female

This is the stereotype problem from the inside. A label meant to free someone from gender expectations ended up controlling their choices more tightly than before.

"You can't pass as non-binary"

Other people judge a person's sex on sight. A non-binary identity therefore usually goes unseen unless the body is changed, and that creates pressure toward medical transition:

…people will always first perceive me as male or female no matter what and that there is no way to pass as nonbinary. I always felt pressured to go on hormones just so people would take me seriously as a trans person… —mantis_princess, desisted female

The same commenter concluded that even declaring herself "not a woman" put too much weight on gender. What she wanted was a life in which gender did not matter to her at all, and accepting being a woman turned out to be the way to get there.

A stepping stone in both directions

For some people non-binary was the first step toward binary transition. "I identified as non binary when I was 14 and less than a year later, trans guy" (JoplinIsFree, detrans female). One desisted male described it as a step on the way to escaping manhood that stopped short only because he could not pass as female:

…when being nonbinary was an escape from homophobia and feeling like i was inferior for having interests and mannerisms that aren't masculine, what did that say about my view of femininity? —Majestic-Date-4825, desisted male

For others it was a halfway house on the way out. One detrans female who had lived as a man said non-binary "felt like the natural (at the time) step from man to 'something that was not a man'", and that she "was not ready to accept the fact that I made a huge mistake" (Playful-Score-67, detrans female). See desistance and social transition.

Sexuality and trauma underneath

Some people found that the label had covered something else. For a lesbian, identifying as non-binary was "sort of a coping mechanism", and it mainly helped her "dissassociate from being a lesbian and not wanting to feel like a 'wrong' woman" (fir3dyk3, desisted female; see internalised homophobia). For another woman who took low-dose testosterone and nearly had a mastectomy as a non-binary person, it was childhood abuse:

I thought that discomfort and repulsion meant I was non-binary, when really I just subconsciously expected that it would be the answer to all of my problems if I simply identified my way out of this trauma and the sociocultural reality of what it means to be a woman. —No-Analysis-3065, detrans female

This matches survey findings that many detransitioners came to see their distress as linked to trauma or mental health conditions (Littman 2021; Littman et al. 2024), and that many reported a need for support with internalised homophobic and sexist prejudices (Vandenbussche 2022).

Being offered the label again

Some people who detransition say therapists or queer friends immediately suggest a non-binary identity instead, as though some label has to be kept. "Did anyone else find when you explained your feelings towards gender now, your queer friends would try to suggest you might be non-binary, agender, or genderfluid? I got all three" (verytiredcatto, detrans male).

Not every detransitioner drops the label. In Littman's survey a quarter identified as non-binary at least in part after detransitioning (Littman 2021). Some people who stop hormones for health reasons keep a non-binary or trans identity, and they are not well represented on r/detrans.

Where the labels came from

From "genderqueer" to "non-binary"

The word genderqueer became prominent in the mid-1990s. The Oxford English Dictionary's earliest evidence for it is from 1995, in In Your Face, the newsletter activist Riki Anne Wilchins produced alongside the direct-action group Transexual Menace (OED; Digital Transgender Archive). In that period it worked more as a political stance than a personal identity: Wilchins framed the fight against gender oppression as being about "all of us who are genderqueer", a list that ran from butch lesbians and effeminate gay men to cross-dressers and transsexuals (them. 2021).

That original idea is the feminist one: gender roles are a social burden, and people should be free to ignore them. The 2002 anthology GenderQueer: Voices From Beyond the Sexual Binary moved the term further. By the late 1990s the internet was spreading the term: the SPHERE mailing list, created in 1997 for people who identified as "both genders, or no gender, or third-gendered", was one early hub (them. 2021). Over the next two decades the meaning drifted away from "everyone should be free of gender rules" and toward "some people have a special inner gender that is neither male nor female". That drift is what turned a critique of stereotypes into an identity built on them.

Tumblr and the micro-identity explosion

The real explosion happened on Tumblr in the early 2010s. The acronym MOGAI ("Marginalized Orientations, Gender Alignments and Intersex") was coined there around 2014–2015 by a user who, according to a history written by one of the term's defenders, was fourteen at the time (mogai-archive history). A blog called mogai-archive collected newly invented gender terms. It ran for about nine months from mid-2014 and posted more than 230 of them. The term xenogender was coined in a submission to that blog in 2014 (mogai-archive history). Xenogenders typically take a subject a person feels connected to, such as cats, food or a game, add "-gender", and come with matching neopronouns. The concept had a second wave on TikTok and Twitter around 2021 (meme.com: Xenogender).

Detransitioners who were on Tumblr at the time describe the same timeline from the inside:

It went into the neogender and neopronoun world in the very early 2010s with the MOGAI movement on Tumblr. It was intended to be a sort-of strategy to break up cishet norms, but people began to actually identify with the labels. —Upset-Elderberry3723, desisted male

I joined tumblr a couple years before the whole trans explosion… I then started identifying as 'queer' after a year of being out as gay, then later as non-binary. —fir3dyk3, desisted female

The way these labels spread matters for how we understand them. Most of them were not found through clinical observation or long-standing cultural practice. Young people invented them in online communities that rewarded new identities with attention and belonging (see social contagion and peer influence and echo chambers). That does not prove every non-binary person is following a trend. It does mean the speed and age profile of the spread call for caution before anyone builds medical decisions on these labels.

Not the same as "third gender" cultures

Supporters often point to third-gender cultures, such as the hijra of South Asia or fa'afafine in Samoa, as proof that non-binary identities are ancient. These are different things. Those roles are long-standing social categories, usually tied to sex, sexuality and a specific community role. They are not an individual's private sense of inner gender, and they do not come with a long list of self-chosen sub-labels. Using them to justify Tumblr-era micro-identities skips over that difference.

Prevalence trends

Non-binary identification has grown very fast, especially among young people and especially among females. The figures below come from surveys with different methods and should not be compared too directly.

Three patterns stand out. The rise is concentrated in one generation. Females are over-represented. And non-binary people are now a large share of patients in gender clinics and surgical practices. The Trevor Project's list of labels shows how fragmented the identity is: non-binary youth also described themselves as genderfluid (24%), genderqueer (23%), androgynous (23%), agender (15%), demigirl (10%) and more (Trevor Project 2021). It is worth noticing that "gender non-conforming" (27%) and "androgynous" (23%) appear as identities in that list. They describe how a person looks and behaves, not a separate kind of person.

Limitations: the Trevor Project recruited through targeted social-media ads, so its sample is self-selected and online-heavy. Pew and Gallup are representative surveys but rely on self-report, and none of these sources can say how stable the identities are over time.

Medical transition of non-binary people

WPATH SOC-8 and the non-binary chapter

Version 8 of the WPATH Standards of Care, published in 2022, gave non-binary people their own chapter for the first time (Coleman et al. 2022). The chapter says non-binary people may want any combination of hormones and surgeries, including interventions usually linked to binary transition. It warns clinicians that a non-binary patient's gender nonconformity should not be "assumed to be indicative of clinical complexity". It also lists clinicians who doubt that a non-binary gender is valid among the barriers non-binary people face (tandfonline full text).

In practice this means a growing group of patients is offered body-altering interventions on the basis of an identity that, by its own definition, has no fixed physical goal. With a binary transition there is at least a stated end point: looking like the opposite sex. With a non-binary transition the end point is whatever the patient wants at the moment. That makes informed consent and outcome measurement much harder (see informed consent critique).

"Low-dose" hormones and the myth of picking effects

A common non-binary request is low-dose testosterone ("microdosing") for females, or low-dose estrogen for males, in the hope of getting a few chosen changes and nothing else. Trans commenters who take testosterone themselves often explain why that hope is misplaced:

If you're on T long enough, you WILL be masculinized. —gothwerewolf, trans man (FTM)

Another trans commenter described a friend whose testosterone sat between the female and male ranges for 18 months, which their physician called "microdosing menopause". The commenter explained that this level brings neither masculinising puberty nor relief from the effects of low hormone levels (quinoabrogle, trans man (FTM)). Some of the fastest changes, such as voice and genital growth, are also among the least reversible (see testosterone in females).

Detransitioners make the same point and add a warning about what non-binary youth are being told:

…it seems many non binary identifying trans people do take HRT and are misled about being able to pick and choose effects, which is very much not the case. —DetransIS, detrans intersex female

There is no such thing. The human body simply doesn't work that way. Either the dose will be too low and nothing will happen, or it will be high enough to suppress your T production… —recursive-regret, detrans male, on low-dose estrogen in males

For males, see estrogen and testosterone blockers in males.

Top surgery without testosterone

Non-binary transition has created a new surgical pathway: mastectomy for females who are not taking testosterone and do not identify as men. One clinical commentary calls this the surgery most specifically associated with non-binary patients (Vincent 2018). In the UCLA cohort, every non-binary female patient had completed or wanted surgery, but only 30% were on hormones (UCLA cohort). In the chest-surgery study, non-binary patients were significantly less likely to use testosterone, and more of them had breast reductions instead of full mastectomy (PRS Global Open 2024).

Some detransitioners describe exactly this route, and say it was driven by something other than their chest:

I didn't have dysphoria either, and mostly got top surgery because I felt like it would legitimize my trans feelings to the world, and myself… For me, it's that I had deep-seated shame about being a gender non-conforming woman. —Euphoric-Ad-637, detrans female

I identified as non-binary for a long while because for me it was the only way to get the chest surgery I wanted. —autisticdragon69, detrans female

See also top surgery regret.

The evidence gap

There is very little outcome research specific to non-binary people. The Cass Review found the evidence for hormonal interventions in young people to be weak overall and stressed that young people's identities are often not fixed (Cass 2024). The non-binary subgroup has been studied even less. The chest-surgery outcomes study above measured satisfaction only after surgery, and just under half of patients responded. Like most of this literature, it did not follow patients over the long term.

Some of the most relevant findings suggest non-binary identities are less stable than binary ones. In a US gender clinic, 29% of 68 adolescents changed their requests for medical transition over time, and these shifts were significantly more common among non-binary youth (Cohen et al. 2023). The authors called these shifts "not uncommon". They concluded that clinicians need to keep clarifying goals and stop-points, which is hard to do when the identity itself has no defined physical end point.

Detransition research shows that non-binary identity appears at both ends of the process. In a survey of 100 detransitioners, 15% identified as non-binary when they began transitioning and another 3% as both transgender and non-binary. After detransition, 14% identified solely as non-binary and another 11% as non-binary plus another label (Littman 2021). In a study of 78 young adults who stopped identifying as transgender, the researchers deliberately included former non-binary and agender identities in their definition of "transgender" (Littman et al. 2024). Non-binary is therefore a destination for some people leaving binary transition, a route into it for others, and a stopping point for some.

How non-binary people describe themselves

Non-binary people describe their identities in varied ways, and some of their descriptions support parts of the argument above.

For some, the identity is mainly about not being seen as their sex:

I'm nonbinary, so it's not so much that I want to be seen and perceived as a man, but that I really really don't want to be seen as a woman. —meringuedragon, non-binary (r/ftm)

Others describe a lasting tension with a world organised around two sexes. One person on low-dose testosterone after top surgery wrote that their "genuine dream scenario is someone pausing in confusion unsure how to address me", and that living as non-binary "feels right" despite having to explain it constantly (enbyslamma, non-binary (r/ftm)).

Binary trans people do not always agree with non-binary framings either. One trans woman said she has "seen some trans people identify with non-binary as a crutch because they didn't feel confident in their womanhood" (Forsakened_Bia, trans woman (MTF)). A trans man explaining why he identifies as male instead of non-binary made the same argument detransitioners make about nonconformity:

"I feel like a man who doesn't conform, not a neutral third thing or a mixture"… Men are not a monolith. —ZobTheLoafOfBread, trans man (FTM)

That sentence, "men are not a monolith", is the central point of this page. It applies to men and women of every kind.

Living without the label

People who left non-binary identities often describe the relief of simply being their sex with no conditions attached. They can be masculine, feminine, both or neither, without that saying anything about what they are:

I promise you a lot of women feel the exact same way. Womanhood isnt really a 'thing' per se. —[deleted], r/detrans commenter

If you are questioning a non-binary identity or thinking about hormones or surgery, it can help to talk to a therapist who will explore your feelings without steering you toward any answer. The support directory lists gender-exploratory therapists and detransitioner peer groups. More research is in the study archive, and first-person accounts are in the video archive.
