The Myth of the “Six Genders in the Talmud”

From time to time, we encounter claims that seem almost too neat to withstand closer scrutiny. One such claim that has gained considerable traction is the assertion that ancient Jewish law recognized six, or, in some versions, even up to eight, genders, or, more specifically, biological sexes, and that this recognition has persisted for two thousand years.

This idea appears frequently in social media discussions, educational presentations, and even in sermons. Often, it is presented with a sense of certainty, as if it can resolve a debate before any real discussion has taken place.

However, a closer look shows that the popular version does not quite align with what the ancient sources actually say. There is indeed a kernel of truth here: the rabbis did discuss more than just two categories of human bodies.

But moving from that fact to the assertion that Judaism has recognized six genders for two thousand years overlooks much of the historical context and nuance. In fact, as we will see, the sources do not really propose six sexes either. They assume two, and then think with unusual honesty about the ways real bodies complicate that assumption.

To understand what is really at issue, we need to look more closely at what the sources actually say, the purposes these categories served, how the rabbis applied them to real people, and how the modern interpretation came to be attached to them.

What the Rabbis Actually Discussed

Let’s start with the honest part of the claim. Ancient rabbinic literature really does name several categories of human beings beyond a simple pairing of male and female. Most scholars count six, though some count seven depending on how the categories are split. These are the categories involved.

Zachar is a male. Nekevah is a female. These are the two familiar poles, and they carry the bulk of legal attention throughout rabbinic writing.

Androgynos describes a person with both male and female sexual characteristics. This category is discussed in some detail in Mishnah Bikkurim 4, where the rabbis work through which laws apply to such a person and which do not.

Rabbi Meir stated it this way, that the androgynos is a creation of its own image, and that the sages could not determine if the androgynos is male or female.

Tumtum describes a person whose sexual characteristics are indeterminate or hidden, so that the person cannot be readily classified. This category also appears in Mishnah Bikkurim 4. It is worth noting that, in the classical view, tumtum was often treated not as a distinct third sex but as a state of doubt between male and female.

Rabbi Meir’s position in the Mishnah captures this: such a person is sometimes treated as a man and sometimes as a woman, precisely because their status is uncertain rather than settled. This detail matters because it shows that even within the tradition, some of these categories served as tools for resolving uncertainty about sex, rather than as affirmations of a separate identity.

There were also different views here, such as we see in Chagigah 4a, where Abbaye states that a tumtum who possesses descended testicles, and this was visible, should be considered a male. Rashi explains this as we should assume the full male genitals are present, but they are simply hidden.

Ay’lonit refers to a person assigned female at birth who does not develop typical female secondary sex characteristics and is infertile. The discussion appears in tractate Yevamot, particularly around Yevamot 80–81, alongside the related treatment of the saris.

Saris refers to a person assigned male at birth who does not develop typical male secondary sex characteristics, or who is infertile.

The rabbis distinguish two kinds. A saris hamah is one who is so from birth or by nature, and a saris adam is one who became so through injury or castration. Because of this split, some lists count seven categories rather than six. (The occasional “eight” count comes from applying a similar natural-versus-induced split to the ay’lonit as well, a further subdivision that is more a modern extrapolation than a fixture of the classical lists.)

Now, when we read these categories plainly, we see that they are not especially exotic or mysterious. Rather, they reflect a legal system’s effort to account for the real diversity of human bodies that might come before a judge.

It is important to notice what is absent from these definitions. There is no mention of how a person feels about themselves, no indication of how someone wishes to be perceived, and no reference to an internal sense of identity. Each of these categories is rooted in observable physical characteristics and reproductive capacity.

Just as a side note, when the sources say the ay’lonit and sarid “did not develop secondary sex characteristics,” they mean something quite definite.

The baseline test was the absence of pubic hair by age twenty (some say eighteen), supplemented by a checklist of further signs: for the ay’lonit, no breasts, pain during intercourse, an underdeveloped lower abdomen, and a deep voice; for the saris, no beard, sparse hair, and smooth skin.

Crucially, these signs were not the definition of a new sex. The person’s primary anatomy already establishes them as a man or a woman. The secondary signs were read as evidence of something else entirely, an inability to reproduce.

The rabbis were using the observable body, according to the medical assumptions of their day, as a proxy for fertility, because fertility was what the surrounding laws of marriage, levirate marriage, and lineage actually turned on.

Simply put, these individuals did not go through the expected pubertal changes, and based on that, rabbis read that failure as a sign of infertility.

Why the Rabbis Bothered

To understand why these categories exist at all, it helps to remember what rabbinic law is trying to do.

Jewish law assigns different obligations and privileges to different people, and many of those distinctions historically ran along the line of male and female. That means the law needed a way to handle the people who did not fit neatly on either side of that line.

The rabbis needed to determine who was obligated in which commandments, who may marry whom, who inherits property, who may serve as a priest, and who counts toward the quorum for certain rituals.

When a body does not present a clear answer to “male or female,” a legal system that depends on that distinction needs a way to respond. That is the role these categories serve: they are tools for halakhic reasoning throughout the literature, not theories of anyone’s inner experience.

The scholar Charlotte Fonrobert has argued this point persuasively, reading the androgynos as a kind of theoretical test case for the binary structure of Jewish law, comparable to the way the koi (an animal hybrid, between a domesticated and wild animal) functions as a test case within another legal binary. The categories, on this reading, exist to shore up the system, not to celebrate variation for its own sake.

She argues that the primary concern here is to uphold the binary gender-grid of Jewish law. What they point out is that even here, when talking about someone who is androgynous, they must dress like a man, and most significantly to this discussion, they may take a wife, but could not be taken as a wife. The assumption was that the male genitalia had greater signifying force.

Whenever we discuss the Talmud, we do have to be a bit careful, as there are often dissenting voices. One such voice was Rabbi Yossi, who, in the same vein as Rabbi Meir above, argued that those who were androgynous were creatures in their own right, and that sages could not declare them either man or woman.

In this case, with the idea of an androgynous person, we do get the closest to a third category, but such dissent, which would frame it as such, is in the minority.  

Now, a natural question is whether the rabbis were describing actual individuals who came before them. For the most part, they were not, or at least, they did not record them that way. The discussions are overwhelmingly framed as generalized legal cases: an androgynos who betroths, a tumtum who inherits, and so on.

Where the sources do name specific individuals, those individuals are scriptural or legendary. The Talmud famously reinterprets Abraham and Sarah as having originally been tumtumim, an explanation offered to account for their prolonged infertility before Isaac’s miraculous birth; a competing view instead recasts Sarah as an ay’lonit.

There is also a midrash that reads the first human, Adam, as an androgynous person whom God later separated into male and female. The Adam case is something of an outlier, since it concerns the origin and division of the sexes rather than a question of fertility.

But the other named cases turn squarely on reproduction: Abraham and Sarah’s tumtum status is invoked to explain their long infertility. In each of these, the category does the work of explaining a reproductive failure or a body later made fertile, rather than anything resembling an inner sense of identity.

Even the Adam midrash, for its part, resolves into the familiar binary, with the androgynos separated into a distinct male and female rather than standing as an enduring third sex.

The one genuinely non-legendary individual, an adult tumtum from the town of Bairi, appears precisely because surgery removed the covering skin, after which he was reclassified as a man and went on to father seven children. In other words, even the rabbis’ rare “real” case resolves back into the binary and back into the question of who can reproduce.

How the Rabbis Actually Determined These Categories

If the categories rest on the body, a natural question follows: how did the rabbis expect anyone to know which category applied? The answer tells us a great deal about what these categories are and are not.

The assumed method was physical, visual inspection of the body, not self-report or social perception. But the categories differ sharply in how that inspection played out.

For the androgynos, the relevant characteristics were externally visible. The rabbis could see both male and female features; what they could not do was decide which set governed. The difficulty here was legal and conceptual, not diagnostic, which is why one major opinion treats the androgynos as a category in its own right rather than as a case of doubt.

The tumtum is the opposite case, and it is the one that most directly answers the question. The entire definition of the tumtum is built around the failure of visual inspection: the sexual organs are recessed or covered, so the body cannot be read at a glance.

The rabbis did not respond to this by inventing a “perceived” or self-declared status. They assumed there was a true, determinate sex underneath that examination would ideally reveal, and they created a legal status of doubt, safek, to govern the person until it could be.

The sources go further still, contemplating surgical examination to resolve the matter. Maimonides notes that an operation could potentially reveal male or female genitalia and thereby settle the person’s status, and the Talmud records an actual case of an adult tumtum whose covering skin was cut away, after which he was recategorized as a man and went on to father seven children.

This is the heart of the matter. The tumtum is not a third sex, the rabbis affirmed. It is a placeholder for unresolved anatomical doubt, one they were prepared to resolve by examination or even surgery where feasible, and one they governed by stringency in the meantime, ruling so as to account for both possibilities at once.

There are two cautions we have to hold in mind to keep this precise. First, the rabbis’ methods were those of the ancient world; their descriptions of the tumtum do not map neatly onto any single intersex condition recognized by modern medicine, so we should describe their attempt to read the body without overstating its diagnostic precision.

Second, and more importantly for our purposes, a system that sorts people by inspecting anatomy and resolving doubt about it is a world away from a modern framework of self-identified gender.

It Is Largely About the Capacity to Procreate

If we look closely at the categories, a further pattern emerges: much of this turns on the ability to reproduce.

This is clearest with the saris and the ay’lonit, because for them, fertility is not merely one factor but the whole definition. Neither is a case of ambiguous anatomy.

Their anatomy is typically unambiguous. What sets them apart is that they do not develop as expected at puberty and cannot bear children. The ay’lonit, for instance, is described as a woman who does not develop typical female characteristics and cannot conceive, and the identification is often retrospective and functional, confirmed by reaching a certain age without the expected signs, rather than by inspecting unclear genitalia.

In regard to both the any’lonit and saris, the discussion centered largely around levirate marriage, which existed specifically to produce an offspring for a childless brother who passed away. In the case of an ay’lonit, the Yevamot discussion is about whether they were bound by the levirate obligation.

It is also important to note that the identification was, more often than not, retrospective and functional. It was more of a diagnosis based on reproductive outcomes.

Even the two anatomically ambiguous categories bend back toward reproduction. The tumtum whose true sex is revealed promptly re-enters the reproductive economy, as in the Talmudic case of the man who fathered seven children after surgery.

The androgynos discussions are heavily concerned with marriage and its validity, which in the rabbinic frame is inseparable from procreation.

Beneath the whole system runs this single current. So many of the law’s male-and-female distinctions, from marriage and levirate marriage to inheritance through offspring and priestly lineage, exist to order the transmission of family and descent.

That is why a legal system organized along the lines of male and female cares so intensely about these edge cases: they are precisely the points where the reproductive machinery of the law stalls.

Not Six Sexes, But Two Sexes Complicated by Reproduction

Here we arrive at the point that even the careful “six sexes, not six genders” correction tends to miss. When we lay the categories side by side, it becomes clear that the rabbis are not really proposing six biological sexes at all. They assume two, and then reckon honestly with the ways real bodies fail to declare or deliver on that binary.

Consider how each of the non-binary categories actually behaves. The tumtum is explicitly a state of doubt about which of two sexes a person is; the entire apparatus presumes a real, determinate male or female underneath, currently hidden, which is why examination or surgery can dissolve the category and re-sort the person.

A classification that can be resolved simply by looking more closely is not a third sex. It is an epistemic placeholder.

The saris and the ay’lonit are not anatomically ambiguous in the least. In the rabbis’ own language, a saris is a kind of man, and an ay’lonit is a kind of woman. The nouns stay binary; what changes is reproductive function, not sex classification. These are not new sexes but familiar sexes whose bodies do not perform the reproductive role the law was organized around.

Only the androgynos has any serious claim to standing outside the binary, and even there the tradition is divided. One voice does call it a creature unto itself, but the more common approach is to ask, feature by feature, which of the two existing bodies of law applies, treating it as a both/and problem within a binary system rather than the founding of a distinct third sex.

So of the celebrated “six,” two are simply the binary itself, two are the binary complicated by infertility, one is doubt about which side of the binary applies, and only one is even a contested candidate for a category of its own. What looks like a taxonomy of six sexes is really something more subtle and, I would argue, more interesting: a binary sex model colliding with the messy reality of anatomy and, above all, fertility.

Put differently, the rabbis are working not with one axis of six values but with two intersecting variables.

The first is sex, which remains fundamentally binary even when it is uncertain or hidden. The second is reproductive capacity, which is neither binary nor simple.

Cross those two axes, add the complication of a body that cannot always be read at a glance, and the “six categories” fall out naturally, not as six sexes but as the predictable results of a two-sex system meeting real human variation.

This is worth stating carefully. The claim is not that the rabbis unanimously held there are exactly two sexes; the androgynos remains a genuine and unresolved edge case, and some modern scholars lean on precisely that minority voice.

The claim is that the system’s dominant logic is binary, and that the famous list is best understood as that binary, complicated by reproduction and legibility, rather than as a proud roster of six distinct sexes.

The Word “Gender” Is Doing a Lot of Work

With all of this in view, we can see just how much weight the popular claim places on a single modern word. The term “gender” carries a wide range of meanings that simply do not apply to these ancient categories.

Today, when people use the word “gender,” they often refer to aspects of identity, personal expression, or an internal sense of self that may or may not correspond to one’s physical body. That conceptual framework is a development of the twentieth century.

In the ancient world, there was no concept of “gender identity,” “gender expression,” or a “gender spectrum” as we understand those terms today. So when a modern post translates terms like androgynos or tumtum as “genders,” it introduces a contemporary idea into an ancient context and then presents it as if the original authors shared that idea.

It is worth acknowledging a subtler version of the argument here. Some readers point to rabbinic discussions in which gendered obligations track “local custom,” suggesting the rabbis had at least an implicit awareness that certain gendered behaviors are socially conditioned rather than fixed by anatomy.

That observation has some merit, but it concerns matters of expression and custom at the margins, not the core categories themselves. Those categories remain grounded in anatomy and reproductive capacity, and awareness that some behaviors vary by custom is a far cry from a theory of gender identity.

The rabbis were classifying bodies for legal purposes, addressing questions that are quite different from those posed by modern readers.

This is not to criticize the rabbis in any way. In fact, they demonstrated a remarkable attentiveness to the diversity of human bodies, often more so than later interpreters recognized. But it is important to be precise.

Recognizing variation in physical bodies is not the same as articulating a theory of gender identity, and conflating the two leads to claims that the sources themselves cannot support.

Fifteen Centuries of Silence on the Modern Reading

If the idea of “six genders” were truly an ancient teaching, we would expect to find it reflected in the writings of the great interpreters who devoted their lives to studying these texts. Yet we do not find such echoes.

The medieval and early modern commentators who engaged with these texts, figures such as Rashi, Maimonides, the Tosafists, and the authors of the Shulchan Aruch, consistently treated these categories in terms of anatomy and law.

Maimonides, for instance, defines the tumtum in strictly anatomical terms, as a person in whom neither male nor female genitalia are discernible. There is no evidence that these commentators read such terms as statements about psychology, personal identity, or an inner sense of gender.

For approximately fifteen hundred years, from the rabbinic period through the modern era, there is no evidence that anyone connected these categories to what we now refer to as gender.

This long period of silence is telling. It indicates that the modern interpretation is not a tradition handed down through the generations, but rather a recent addition.

When the Modern Connection Was Actually Made

So when did the two worlds meet? The timeline is surprisingly clear and recent.

The modern idea of gender as something distinct from biological sex emerged over several decades in the twentieth century. In the 1960s, researchers, including John Money, developed early frameworks around gender identity. In the 1970s, feminist theory and social constructionism sharpened the distinction between sex and gender. In the 1980s, queer theory and scholarship shaped by Michel Foucault pushed the conversation further.

Through all of this, no one was reaching back to the Talmud. The new ideas were being worked out on their own terms.

The first careful scholarly attempts to read rabbinic categories alongside modern gender theory appeared in the 1990s. They largely drew on Jewish feminist scholarship, queer Jewish studies, and academic work on intersex bodies in antiquity, including the work of scholars such as Daniel Boyarin and Charlotte Fonrobert. These early efforts were modest.

They drew on a broader reorientation in the field. Daniel Boyarin’s Carnal Israel (1993) had argued that rabbinic Judaism understood the sexualized body in a way profoundly different from Christianity, organized around marriage and the generation of offspring rather than ascetic renunciation.

Building on that framework, Charlotte Fonrobert turned to the specific categories, the androgynos, the tumtum, and the rest, and showed how they functioned as test cases for the law’s binary structure.

They did not claim the rabbis possessed a concept of gender. They observed that rabbinic law showed awareness of biological variation, which is a much smaller and much more defensible claim.

Through the 2000s and 2010s, the idea spread into progressive Jewish spaces. A pivotal popular text was Rabbi Elliot Kukla’s 2006 work, which framed the classical categories as illustrating that the Western gender binary is not universal across all cultures.

From there, the idea appeared in Reform and Reconstructionist educational materials, in the work of LGBTQ Jewish organizations, and in a growing stream of online articles and infographics. In that migration from seminar room to social feed, the careful distinction between sex categories and gender identities began to blur.

By the 2010s, this idea had taken on a life of its own, often appearing as a meme with the phrase “Judaism has recognized six genders for two thousand years.” It is not difficult to understand why this statement spread so widely.

It is concise, carries an air of scholarly authority, and appears to present a modern debate with an ancient foundation. However, it is historically inaccurate.

Scholars have repeatedly pointed out that the Talmud recognizes categories of sex, not gender identities, and that these categories are legal rather than psychological.

Indeed, the scholarly conversation is more complicated than the meme lets on: while some see the categories as an invitation to locate contemporary trans and intersex lives within rabbinic history, others, such as Max Strassfeld, caution that these same texts can read as instances of the rabbis regulating and constraining bodies rather than affirming them.

Either way, the connection to modern ideas about gender is an interpretive overlay, not a continuous tradition.

How to State This Accurately

There is, however, a way to discuss these matters that remains faithful to the original sources. While it may not be as catchy as the popular meme, it has the important virtue of being accurate.

Ancient rabbinic law works with a fundamentally binary understanding of sex, male and female, and then develops a sophisticated body of reasoning about the cases that complicate it.

Some bodies do not clearly declare which sex they are (the tumtum). One presents features of both, and the tradition never fully settles how to classify it (the androgynos). And some, most commonly, do not deliver on the reproductive roles the binary was built around (the saris and the ay’lonit).

These are not six sexes standing side by side. There are two sexes, and a careful law about the ways real bodies complicate them.

Those distinctions are grounded in anatomy and reproduction, and they exist to resolve real questions about obligation, marriage, inheritance, and ritual status. They were, where possible, determined by examining the body, and much of their legal weight rests on questions of who can marry and who can reproduce.

They are neither identities nor evidence that the rabbis held a modern theory of gender. The connection between these categories and contemporary ideas about gender identity is a late twentieth-century reinterpretation, not an ancient teaching.

In short, the Talmud offers us something far more compelling than the meme suggests, and for reasons that the meme entirely overlooks. It reveals a legal tradition that was willing to examine the full diversity of human bodies and to think carefully about how the law should respond to that diversity, without ever abandoning the two-sex framework that diversity complicated.

This is a genuine and, in many ways, moving aspect of the tradition. It deserves to be described with accuracy, rather than reduced to a simplistic slogan.

Why the Accuracy Matters

At this point, one might reasonably ask why it matters to be so precise. If the claim helps people feel included, is it really necessary to focus on dates and definitions?

The answer is rooted in the principles that guide any honest engagement with the past. When we use ancient texts to support modern arguments, we often hear our own perspectives echoed back to us, mistaking them for the voices of those who came before.

This tendency is problematic, regardless of which side of a debate it serves. It replaces the unique and sometimes challenging features of the sources with a reflection of our own views. If we are to take a tradition seriously, we must be willing to read it on its own terms, even when those terms do not align with our preferred conclusions.

The rabbis engaged in careful and, at times, surprising work as they considered the human bodies before them. The most respectful approach we can take is to describe their efforts honestly, to acknowledge them for what they truly were, and to resist the urge to attribute to them ideas they never intended to express.
