Yoma 43a ~ Androgyny and the Fluidity of Gender

The Torah proscribes a series of steps required to render a person spiritually pure. One of those steps (Numbers 19:17) is to pour spring water on the ashes of a sacrificed animal. But who is qualified to do the pouring? The Talmud cites a Mishnah (Parah 5:4) that tells us:

יומא מג, א

מֵיתִיבִי: הַכֹּל כְּשֵׁרִין לְהַזּוֹת, חוּץ מִטּוּמְטוּם וְאַנְדְּרוֹגִינוֹס וְאִשָּׁה. וְקָטָן (שֶׁיֵּשׁ) בּוֹ דַּעַת, אִשָּׁה מְסַיַּעְתּוֹ וּמַזֶּה.

Everyone is qualified to sprinkle the purification waters, except for a person whose sexual organs are concealed [tumtum], and a hermaphrodite [androginus], and a woman. And concerning a minor who has a basic level of intelligence, a woman may assist him and he sprinkles the purification waters.

Today we will explore the nature of these two mysterious categories known as the tumtum and the androginus. We also posted this about a year ago while studying Shabbat, but hey, lots of people have subscribed to Talmudology since then, and be honest, can you recall that post in detail? No? Then read on…

The tumtum is a person whose genitalia are somehow hidden or covered, so that it is not known if they are male or female. In contrast, the genitalia of the androgyne (an ancient Greek word formed from ἀνδρός  andros - “man” and γυνή gune, - “woman”) are in plain sight. It just isn’t clear whether they are male or female organs. The two are mentioned on at least twenty-three pages of the Babylonian Talmud, and in no fewer than nine halachot in the Jerusalem Talmud, so let’s figure out what, from a medical perspective, they are.

The Tumtum

There is no ambiguity about the gender of a tumtum. We just need to get a glimpse of the genitals. (The eleventh century dictionary known as the Aruch connects the word tumtum with the word atum (אטום), meaning sealed.) The problem is that the genitals are covered by what is usually described as skin. Once this cover is surgically opened, the gender will be revealed. In fact according to Rav Ammi (Yevamot 64a), both Abraham and Sarah were each a tumtum. Yes, you read that correctly. Each had genitalia that were hidden. Rav Ammi suggests this as an explanation as to why the couple were infertile for so many years. Once the covering had been removed the couple could then procreate as normal, and along came Isaac.

אמר רבי אמי אברהם ושרה טומטמין היו שנאמר (ישעיהו נא, א) הביטו אל צור חוצבתם ואל מקבת בור נוקרתם וכתיב (ישעיהו נא, ב) הביטו אל אברהם אביכם ואל שרה תחוללכם

Rabbi Ami said: Abraham and Sarah were originally tumtumin, as it is stated: “Look to the rock from where you were hewn, and to the hole of the pit from where you were dug” (Isaiah 51:1), and it is written in the next verse: “Look to Abraham your father and to Sarah who bore you” (Isaiah 51:2),

רשי:

חוצבתם - נעשה לו זכרות: “Hewn”: He was made into a male

נוקרתם - נעשה לה נקבות : “From where you were dug” which made here a female

Urologists have yet to identify this syndrome.

The Androgyne

In 1797 the physician James Parsons, published a book which he dedicated to the Royal Society of London, of which he was a Fellow: “ A Mechanical and Critical Inquiry into the Nature of Hermaphrodites.” Parsons noted that the Romans “had laws made against their Androgyni [which were] remarkably severe; for whensoever a child was reputed one of these, his sentence was to be shut up in a chest alive, and thrown into the sea…

Parsons was not only well-read in Roman law; he cited the fourth chapter of the Mishnah in Bikkurim, which contains a list of the ways in which the androgne sometimes resembles a man, and sometimes a woman:

ביכורים פרק ד

כֵּיצַד שָׁוֶה לַאֲנָשִׁים: מְטַמֵּא בְּלֹבֶן כַּאֲנָשִׁים, וְזוֹקֵק לְיִבּוּם כַּאֲנָשִׁים, וּמִתְעַטֵּף וּמִסְתַּפֵּר כַּאֲנָשִׁים, וְנוֹשֵׂא אֲבָל לֹא נִשָּׂא כַּאֲנָשִׁים, וְחַיָּב בְּכָל מִצְוֹת הָאֲמוּרוֹת בַּתּוֹרָה כַּאֲנָשִׁים:

In what ways is the andogyne like men?…He dresses like men; He can take a wife but not be taken as a wife, like men. [When he is born] his mother counts the blood of purification, like men; He may not be secluded with women, like men. He is not maintained with the daughters, like men…And he must perform all the commandments of the Torah, like men.

כֵּיצַד שָׁוֶה לַנָּשִׁים: מְטַמֵּא בְּאֹדֶם כַּנָּשִׁים, וְאֵינוֹ מִתְיַחֵד עִם הָאֲנָשִׁים כַּנָּשִׁים, וְאֵינוֹ עוֹבֵר עַל "בַּל תַּקִּיף" וְלֹא עַל "בַּל תַּשְׁחִית" וְלֹא עַל "בַּל תְּטַמֵּא לַמֵּתִים" כַּנָּשִׁים, וּפָסוּל מִן הָעֵדוּת כַּנָּשִׁים, וְאֵינוֹ נִבְעַל בַּעֲבֵירָה כַּנָּשִׁים, וְנִפְסַל מִן הַכְּהֻנָּה כַּנָּשִׁים:

And in what ways is he like women?… he must not be secluded with men, like women; And he doesn’t make his brother’s wife liable for yibbum (levirate marriage); And he does not share [in the inheritance] with the sons, like women; And he cannot eat most holy sacrifices, like women…. he is disqualified from being a witness, like women…

The Androgyne & Congenital Adrenal Hyperplasia

Ambiguous genitalia in neonates. From here.

One of the most common causes of androgyny is congenital adrenal hyperplasia (CAH), caused by a mutation in the CYP21 gene. The adrenal glands, which sits atop the kidneys, are where the action takes place. They produce androgens, which are then converted into the potent sex hormone testosterone. In most (95%) cases of CAH, there is a deficiency of the enzyme 21-hydroxylase. As a result, the adrenal glands produce excessive amounts of the virilizing hormone androgen. (It also causes severe salt wasting, which can be very dangerous, but we are not getting into that now. And there are different severities of the syndrome, but you’ve got a limited attention span, so we will keep it simple.) This excessive androgen production does very little in (XY) males; their genitalia look normal. But in genetic (XX) baby girls the androgens affect the external genitalia and they may become ambiguous: the clitoris becomes enlarged, sometimes to the degree that it resembles a penis. In very severe cases the baby girl has what appears to be an empty scrotum, and may be raised as a boy, all the while being an XX girl with CAH.

Today all newborns are screened for 21-hydroxylase. The deficiency can be treated with hormone replacement, and the genital ambiguity may be corrected, although this latter intervention has, over the last decades, become very controversial.

Anecdotally, in the Western world most [intersex] babies were raised as female because the genitalia were easier to reconstruct... clinical experience suggests that cultural factors are very influential. This may be no bad thing as there is no ‘right’ medical answer and the child will have to grow up in the community into which it is born.
— Woodhouse, C.R.J. Intersex Surgery in the Adult. BJU International 2004. 93 (3): 57-65

The androgyne and the hermaphrodite

The Soncino Talmud identifies the androgyne as a hermaphrodite, that is, a person with both male and female genitalia. So does Goldschmidt’s German translation (“der zwitter”). Cases of true hermaphroditism are extremely rare, and there are only a few scattered case reports in the medical literature. (You can read one reported from Sheba Hospital in Tel Aviv here.) Rather than there being two sets, in these cases the genitalia are ambiguous, and although they have both ovarian and testicular tissue the scrotum does not always contain testes.

Alice Dreger, formerly a Professor of Medical Humanities and Bioethics at Northwestern University, (it’s complicated) wrote a terrific (and controversial) book that tackles some of the issues facing intersex people - those who were once called hermaphrodites. In the past, when faced these difficult cases of intersex or ambiguous genders, clinicians focused on what she calls a “gonadal division.” (Since biopsies and genetic sequencing were not available to the rabbis of the Talmud, they, like clinicians, focused on this gonadal division, for what else could they do?) But, she notes,

a system that emphasizes gonadal anatomy above all else suffers from two major deficits. First, it is scientifically questionable, because it relies on the anatomy of the gonads (functioning or not) more than any other considerations. Second, it provides little clinical help, often confusing and harming the patient, and sometimes also the physician.

Instead, she advocates for a description based on etiology and the patient’s needs. “Such an approach would have the salutary effects of improving patient and physician understanding and reducing the biases that are inherent in the use of the current language of 'hermaphroditism'.”

True hermaphrodites: defined as presenting at least one ovary and at least one testis, or at least one ovotestis...The scientific understanding of sexual development has progressed tremendously in the last 125 years, but the existing taxonomy does not reflect that progress. Scientists and clinicians now recognize that the structure of the gonads does not correlate simply with genotype, phenotype, physiology, diagnosis, or gender identity. The anatomy of testicular tissue in women with androgen insensitivity syndrome (AIS) is quite similar to the anatomy of testicular tissue in non- intersex males, yet their physiologies, phenotypes and gender identities differ markedly.

The many Shades of Gender

We are used to think that when an egg carrying an X chromosome meets a sperm carrying an X or Y chromosome, one of two things will happen: a genetic female (46XX) or a genetic male (46XY) with genitalia to match. But in fact it is way more complicated than that. We know that there are at least 14 genes involved in the process of sexual differentiation, and many more will likely be discovered. A mutation or malfunction of any of these has a dramatic effect on the process of gender differentiation. For example if there is a defect in the enzymes involved in producing testosterone, there may be ambiguous external genitalia; deficiency of the enzyme 5α-reductase results in variable degrees of under-masculinized external genitalia and genital ambiguity; individuals with partial androgen insensitivity syndrome may also have ambiguous genitalia, and there is no consensus regarding an optimal sex of rearing them; and newborns with congenital adrenal hyperplasia, may have male appearing genitalia while all the time being 46XX.

We have previously noted the strange effects of yet gene discovered in the 1980s. This sex-determining gene on a tiny bit of the male Y chromosome is called the sry gene. That gene tells the body to develop into a male or female appearing body. Sometimes the sry gene sneaks off of the Y gene and makes its way into the DNA of an XX female. As a result, she will develop male anatomy while genetically remaining an XX female. (Please read that sentence again, just to be sure you have understood it.) And sometimes the sry gene on an XY genetic male can mutate and not work. In that case, the genetic male appears to have the organs of a female, which is what occurs in Swyer syndrome. (You can hear more about the amazing sex-changing effects of sry in this fascinating podcast.)

And then there is the small community in the Dominican Republic where there have been a number of cases in which little girls grow a penis and turn into little boys. These observations were first reported to the scientific community in 1974, and are caused by a deficiency of the steroid 5α-reductase. Here is how the BBC explained what is going on when they reported about it in 2015.

When you are conceived you normally have a pair of X chromosomes if you are to become a girl and a set of XY chromosomes if you are destined to be male. For the first weeks of life in womb you are neither…Then, around eight weeks after conception, the sex hormones kick in. If you're genetically male the Y chromosome instructs your gonads to become testicles and sends testosterone to a structure called the tubercle, where it is converted into a more potent hormone called dihydro-testosterone. This in turn transforms the tubercle into a penis. If you're female and you don't make dihydro-testosterone then your tubercle becomes a clitoris…the reason [some genetic males] don't have male genitalia when they are born is because they are deficient in an enzyme called 5-alpha-reductase, which normally converts testosterone into dihydro-testosterone.

So the boys, despite having an XY chromosome, appear female when they are born. At puberty, like other boys, they get a second surge of testosterone. This time the body does respond and they sprout muscles, testes and a penis.

So gender identity is very complicated. James Parsons, that physician who wrote the book on hermaphrodites in 1797 tackled some of the difficult questions that were addressed in Mishnah Bikkurim: can a hermaphrodite get married? (yes, but to which gender varies by case); can they be a witness? (only if the “predominating sex” is male); can they be ordained as a minister? (no); The rabbis were puzzled as to the “true” gender of the androgyne, and so classified them as sometimes male, and sometimes female. It was the best they could do at the time, and Parsons, writing 1,500 years later did the same. Thanks to modern medicine we have learned why these intersex cases occur, but as a society we have still a long way to go to help make their lives easier.

Yoma 10a ~ On the Origins of Nations

Today’s page of Talmud digresses into a discussion of where we come from.

יומא י, א

וּפָרְסָאֵי מְנָא לַן דְּמִיֶּפֶת קָאָתוּ, דִּכְתִיב: ״בְּנֵי יֶפֶת גּוֹמֶר וּמָגוֹג וּמָדַי וְיָוָן וְתוּבָל וּמֶשֶׁךְ וְתִירָס״. גּוֹמֶר — זֶה גֶּרְמַמְיָא, מָגוֹג — זוֹ קַנְדִּיָּא, מָדַי — זוֹ מַקֵדוֹנְיָא, יָוָן — כְּמַשְׁמָעוֹ, תּוּבָל — זֶה בֵּית אוּנַיְיקִי, מֶשֶׁךְ — זוֹ מוּסְיָא, תִּירָס, פְּלִיגִי בַּהּ רַבִּי סִימַאי וְרַבָּנַן, וְאָמְרִי לַהּ רַבִּי סִימוֹן וְרַבָּנַן, חַד אָמַר: זוֹ בֵּית תְּרַיְיקִי, וְחַד אָמַר: זוֹ פָּרַס. תָּנֵי רַב יוֹסֵף: תִּירָס — זוֹ פָּרַס

From where do we derive that the Persians descend from Japhet? The Gemara answers: As it is written: “The sons of Japheth were Gomer and Magog and Madai and Javan and Tuval and Meshech and Tiras” (Genesis 10:2). The Gemara explains: Gomer, that is Germamya; Magog, that is Kandiya; Madai, that is Macedonia; Javan, in accordance with its plain meaning, Greece; Tuval, that is the nation called Beit Unaiki; Meshech, that is Musya. With regard to Tiras, Rabbi Simai and the Rabbis disagree, and some say the dispute is between Rabbi Simon and the Rabbis: One said: That is Beit Teraiki, and one said: That is Persia. According to that approach, Persia is listed among the descendants of Japheth. Rav Yosef taught: Tiras is Persia.

So according to the Talmud, the Germans, the Cretans (inhabitants of Crete - Kandia in Hebrew and the largest and most populous of the Greek islands), the Macedonians, the Greeks, Macedonians and the Persians all descended from Japhet.

Where did the Indo-Europeans come from?

There are only a limited number of ways that we can reconstruct the origins of Indo-Europeans. One is through DNA testing of both the living and the dead, as we will return to this later. A second way is to look at language as a way of identifying common ancestry. It may not be as precise as DNA sequencing, but as David W. Anthony and Don Ringe pointed out in their 2015 paper The Indo-European Homeland from Linguistic and Archaeological Perspectives, it is possible to reconstruct a prehistoric language such as Proto- Indo-European (PIE), though with many qualifications. “Because the grammar fragment, phonological system, and lexemes that are reconstructible for PIE reveal a coherent, unremarkable human language…the PIE-speaking community might, given the correct integrative methods, be correlated with the reality recovered by archaeology.”

One fact especially makes the connection of prehistoric languages with prehistoric material cultures worth pursuing. Some of the words that we can reconstruct for protolanguages have very specific meanings, and a few refer to technological developments that can be dated independently and correlated with the archaeological record. That is crucial because, in the absence of writing, archaeology yields no direct evidence for the language spoken by the people who made a particular group of artifacts. Under most circumstances, only the indirect correlation of datable artifacts and the words that refer to them can connect linguistic prehistory with archaeology. In this respect, too, PIE is a fortunate case.
— David W. Anthony and Don Ringe. The Indo-European Homeland from Linguistic and Archaeological Perspectives. Annu. Rev. Linguist. 2015. 1:199–219

This linguistic archeology is a complicated business: There are at least ten groups of Indo-European (IE) languages, and, according to Anthony and Ringe, none are closely related to the others.

Determining the order in which they diverged from each other, called subgrouping, has proved surprisingly difficult but a consensus is emerging. It seems clear that the ancestor of the Anatolian subgroup (which includes Hittite) separated from the other dialects of PIE first, so from a cladistic point of view Anatolian is half the IE family. Within the non-Anatolian half, it appears that the ancestor of the Tocharian subgroup (whose attested languages were spoken in Xinjiang, today in western China, until approximately the tenth century CE) separated from the other dialects before the latter had diverged much. It follows that an item inherited by two or more of the daughter subgroups can be reconstructed for “early” PIE only if it is attested in at least one Anatolian language and at least one non-Anatolian language, and such an item can be reconstructed for the ancestor of the non-Anatolian subgroups only if it is attested in one or both of the Tocharian languages and in some other IE language.

The Case of the Word “Wheel”

Thanks to some solid carbon dating, we know that the invention of the wheel-and-axle principle, which first made wagons and carts possible, occurred around 4000–3500 BCE. So by looking at the words for axle and wheel it may be possible to reconstruct the origins of the word, and from there figure out the origins of the peoples themselves.

Wheel terms found in Indo-European language branches.  From David W. Anthony and Don Ringe. The Indo-European Homeland from Linguistic and Archaeological Perspectives. Annu. Rev. Linguist. 2015. 1:199–219.

Wheel terms found in Indo-European language branches. From David W. Anthony and Don Ringe. The Indo-European Homeland from Linguistic and Archaeological Perspectives. Annu. Rev. Linguist. 2015. 1:199–219.

So, for example, the words for wheel and cart/wagon/chariot take one of two common forms, which are thought to be linked with two PIE roots: the root kʷel- "move around" is the basis of the unique derivative kʷekʷlo- "wheel" which becomes hvél (wheel) in Old Icelandic, kolo (wheel, circle) in Old Church Slavonic, kãkla- (neck) in Lithuanian, kyklo- (wheel, circle) in Greek, cakka-/cakra- (wheel) in Pali and Sanskrit, and kukäl (wagon, chariot) in Tocharian A. The root ret(h)- becomes rad (wheel) in Old High German, rota (wheel) in Latin, rãtas (wheel) in Lithuanian, and ratha (wagon, chariot) in Sanskrit.

The Anatolian hypothesis suggests that speakers of PIE lived in Anatolia (mostly modern day Turkey) during the Neolithic period (10,000–4,500 BCE). From there, Indo-European languages spread into Europe and Asia minor around 7,000 BCE. They then split into three major clades: Indo-European languages in Europe, Dravidian languages in Pakistan and India, and Afroasiatic languages in the Arabian Peninsula and North Africa.

The DNA evidence

In a 2015 paper published in the prestigious journal Nature, a massive international team of researchers with backgrounds in evolutionary genetics, archeology, linguistics, evolutionary biology, history and anthropology analyzed the genetic material from 101 ancient humans from across Eurasia. They demonstrated that “the Bronze Age was a highly dynamic period involving large-scale population migrations and replacements, responsible for shaping major parts of present-day demographic structure in both Europe and Asia.” And importantly, they note that their findings “are consistent with the hypothesized spread of Indo-European languages during the Early Bronze Age.”

Our analyses support that migrations during the Early Bronze Age is a probable scenario for the spread of Indo-European languages, in line with reconstructions based on some archaeological and historical linguistic data... Importantly, however, although our results support a correspondence between cultural changes, migrations, and linguistic patterns, we caution that such relationships cannot always be expected but must be demonstrated case by case.

Today’s page of Talmud claims that peoples as diverse as the ancient Germans, Greeks, Macedonians and Persians originally came from a single shared ancestor: Japhet, third son of Noah. Studies from the modern disciplines as diverse as history, linguistics, genetics and anthropology have concluded that Europeans and Iranians shared a common origin in the steppes of Anatolia. Both origin stories remind us that whatever our national identities, we have much more in common with others than we could have ever imagined.

Shabbat 136 ~ The Tumtum, the Androgyne, and the Fluidity of Gender

The Mishnah that we learned two days ago (134b) teaches that certain acts, normally prohibited on Shabbat, are permitted if the Shabbat is the day of a newborn’s circumcision, or brit milah. For example, a newborn boy may be bathed in warm water on Shabbat in preparation for his circumcision. Although such bathing is usually prohibited it was permitted in this instance, because bathing was thought to have important healing properties, But there are exceptions to this exception, also noted in the Mishnah.

שבת קלד,ב

סָפֵק וְאַנְדְּרוֹגִינוֹס — אֵין מְחַלְּלִין עָלָיו אֶת הַשַּׁבָּת. וְרַבִּי יְהוּדָה מַתִּיר בְּאַנְדְּרוֹגִינוֹס

If there was a question about whether or not to circumcise the baby, or if the baby was an androgyne, we do not desecrate the Shabbat [in order to perform the circumcision]. But Rabbi Yehuda permits a Shabbat circumcision in the case of the adrogyne.

Let’s put to one side the case in which there was “a question about whether or not to circumcise” (it has to do with whether the baby was born prematurely, in the eighth month of pregnancy and you can read more about it here), and focus on the androgyne. In today’s page of Talmud we read a statement from the Sifra that excludes two groups of people from the category of being a male (at least in so far as the laws of human valuation is applied).

שבת קלו, ב

 דְּתַנְיָא: ״הַזָּכָר״ — וְלֹא טוּמְטוּם וְאַנְדְּרוֹגִינוֹס. יָכוֹל לֹא יְהֵא בְּעֵרֶךְ אִישׁ אֲבָל יְהֵא בְּעֵרֶךְ אִשָּׁה — תַּלְמוּד לוֹמַר: ״הַזָּכָר״, ״וְאִם נְקֵבָה הִיא״. זָכָר וַדַּאי, נְקֵבָה וַדָּאִית — וְלֹא טוּמְטוּם וְאַנְדְּרוֹגִינוֹס

As it was taught in the Sifra, the halakhic midrash on Leviticus, with regard to the verse: “Then your valuation shall be for the male from the age of twenty years until the age of sixty years, your valuation shall be fifty shekel of silver, after the shekel of the Sanctuary” (Leviticus 27:3). The Sages inferred: “The male” means the definite male but not a tumtum or an androgynus.

Although in the Mishnah in Shabbat only mentioned the case of the androgyne, it is frequently mentioned together with the androgynus. In Jewish law, these two groups are neither completely male or completely female, but are at some times treated as male, and at others female.

The tumtum is a person whose genitalia are somehow hidden or covered, so that it is not known if they are male or female. In contrast, the genitalia of the androgyne (an ancient Greek word formed from ἀνδρός  andros - “man” and γυνή gune, - “woman”) are in plain sight. It just isn’t clear whether they are male or female organs. The two are mentioned on at least twenty-three pages of the Babylonian Talmud, and in no fewer than nine halachot in the Jerusalem Talmud  (and we have written on some of them before). So let’s figure out what, from a medical perspective, they are.

The Tumtum

There is no ambiguity about the gender of a tumtum. We just need to get a glimpse of the genitals. (The eleventh century dictionary known as the Aruch connects the word tumtum with the word atum (אטום), meaning sealed.) The problem is that the genitals are covered by what is usually described as skin. Once this cover is surgically opened, the gender will be revealed. In fact according to Rav Ammi (Yevamot 64a), both Abraham and Sarah were each a tumtum. Yes, you read that correctly. Each had genitalia that were hidden. Rav Ammi suggests this as an explanation as to why the couple were infertile for so many years. Once the covering had been removed the couple could then procreate as normal, and along came Isaac.

אמר רבי אמי אברהם ושרה טומטמין היו שנאמר (ישעיהו נא, א) הביטו אל צור חוצבתם ואל מקבת בור נוקרתם וכתיב (ישעיהו נא, ב) הביטו אל אברהם אביכם ואל שרה תחוללכם

Rabbi Ami said: Abraham and Sarah were originally tumtumin, as it is stated: “Look to the rock from where you were hewn, and to the hole of the pit from where you were dug” (Isaiah 51:1), and it is written in the next verse: “Look to Abraham your father and to Sarah who bore you” (Isaiah 51:2),

רשי:

חוצבתם - נעשה לו זכרות: “Hewn”: He was made into a male

נוקרתם - נעשה לה נקבות : “From where you were dug” which made here a female

Urologists have yet to identify the syndrome responsible for Rav Ami’s teaching.

(It also causes severe salt wasting, which can be very dangerous, but we are not getting into that now. And there are different severities of the syndrome, but you’ve got a limited attention span, so we will keep it simple.) This excessive androgen production does very little in (XY) males; their genitalia look normal. But in genetic (XX) baby girls the androgens affect the external genitalia and they may become ambiguous: the clitoris becomes enlarged, sometimes to the degree that it resembles a penis. In very severe cases the baby girl has what appears to be an empty scrotum, and may be raised as a boy, all the while being an XX girl with CAH.

Today all newborns are screened for 21-hydroxylase. The deficiency can be treated with hormone replacement, and the genital ambiguity may be corrected, although this latter intervention has, over the last decades, become very controversial.

Anecdotally, in the Western world most [intersex] babies were raised as female because the genitalia were easier to reconstruct... clinical experience suggests that cultural factors are very influential. This may be no bad thing as there is no ‘right’ medical answer and the child will have to grow up in the community into which it is born.

The androgyne and the hermaphrodite

The Soncino Talmud and the Koren Talmud identifies the androgyne as a hermaphrodite, that is, a person with both male and female genitalia. So does Goldschmidt’s German translation (“der zwitter”). Cases of true hermaphroditism are extremely rare, and there are only a few scattered case reports in the medical literature. (You can read one reported from Sheba Hospital in Tel Aviv here.) Rather than there being two sets, in these cases the genitalia are ambiguous, and although they have both ovarian and testicular tissue the scrotum does not always contain testes.

Alice Dreger, formerly a Professor of Medical Humanities and Bioethics at Northwestern University, (it’s complicated) wrote a terrific (and controversial) book that tackles some of the issues facing intersex people - those who were once called hermaphrodites. In the past, when faced these difficult cases of intersex or ambiguous genders, clinicians focused on what she calls a “gonadal division.” (Since biopsies and genetic sequencing were not available to the rabbis of the Talmud, they, like clinicians, focused on this gonadal division, for what else could they do?) But, she notes,

a system that emphasizes gonadal anatomy above all else suffers from two major deficits. First, it is scientifically questionable, because it relies on the anatomy of the gonads (functioning or not) more than any other considerations. Second, it provides little clinical help, often confusing and harming the patient, and sometimes also the physician.

Instead, she advocates for a description based on etiology and the patient’s needs. “Such an approach would have the salutary effects of improving patient and physician understanding and reducing the biases that are inherent in the use of the current language of 'hermaphroditism'.”

True hermaphrodites: defined as presenting at least one ovary and at least one testis, or at least one ovotestis...The scientific understanding of sexual development has progressed tremendously in the last 125 years, but the existing taxonomy does not reflect that progress. Scientists and clinicians now recognize that the structure of the gonads does not correlate simply with genotype, phenotype, physiology, diagnosis, or gender identity. The anatomy of testicular tissue in women with androgen insensitivity syndrome (AIS) is quite similar to the anatomy of testicular tissue in non- intersex males, yet their physiologies, phenotypes and gender identities differ markedly.

The many Shades of Gender

We are used to think that when an egg carrying an X chromosome meets a sperm carrying an X or Y chromosome, one of two things will happen: a genetic female (46XX) or a genetic male (46XY) with genitalia to match. But in fact it is way more complicated than that. We know that there are at least 14 genes involved in the process of sexual differentiation, and many more will likely be discovered. A mutation or malfunction of any of these has a dramatic effect on the process of gender differentiation. For example if there is a defect in the enzymes involved in producing testosterone, there may be ambiguous external genitalia; deficiency of the enzyme 5α-reductase results in variable degrees of under-masculinized external genitalia and genital ambiguity; individuals with partial androgen insensitivity syndrome may also have ambiguous genitalia, and there is no consensus regarding an optimal sex of rearing them; and newborns with congenital adrenal hyperplasia, may have male appearing genitalia while all the time being 46XX.

We have previously noted the strange effects of yet gene discovered in the 1980s. This sex-determining gene on a tiny bit of the male Y chromosome is called the sry gene. That gene tells the body to develop into a male or female appearing body. Sometimes the sry gene sneaks off of the Y gene and makes its way into the DNA of an XX female. As a result, she will develop male anatomy while genetically remaining an XX female. (Please read that sentence again, just to be sure you have understood it.) And sometimes the sry gene on an XY genetic male can mutate and not work. In that case, the genetic male appears to have the organs of a female, which is what occurs in Swyer syndrome. (You can hear more about the amazing sex-changing effects of sry in this fascinating podcast.)

And then there is the small community in the Dominican Republic where there have been a number of cases in which little girls grow a penis and turn into little boys. These observations were first reported to the scientific community in 1974, and are caused by a deficiency of the steroid 5α-reductase. Here is how the BBC explained what is going on when they reported about it in 2015.

When you are conceived you normally have a pair of X chromosomes if you are to become a girl and a set of XY chromosomes if you are destined to be male. For the first weeks of life in womb you are neither…Then, around eight weeks after conception, the sex hormones kick in. If you're genetically male the Y chromosome instructs your gonads to become testicles and sends testosterone to a structure called the tubercle, where it is converted into a more potent hormone called dihydro-testosterone. This in turn transforms the tubercle into a penis. If you're female and you don't make dihydro-testosterone then your tubercle becomes a clitoris…the reason [some genetic males] don't have male genitalia when they are born is because they are deficient in an enzyme called 5-alpha-reductase, which normally converts testosterone into dihydro-testosterone.

So the boys, despite having an XY chromosome, appear female when they are born. At puberty, like other boys, they get a second surge of testosterone. This time the body does respond and they sprout muscles, testes and a penis.

So gender identity is very complicated. James Parsons, that physician who wrote the book on hermaphrodites in 1797 tackled some of the difficult questions that were addressed in Mishnah Bikkurim: can a hermaphrodite get married? (yes, but to which gender varies by case); can they be a witness? (only if the “predominating sex” is male); can they be ordained as a minister? (no); The rabbis were puzzled as to the “true” gender of the androgyne, and so classified them as sometimes male, and sometimes female. It was the best they could do at the time, and Parsons, writing 1,500 years later did the same. Thanks to modern medicine we have learned why these intersex cases occur, but as a society we have still a long way to go to help make their lives easier.

Middot 37b ~ The Lineage of the Cohen

On the very last page of the tractate Middot that deals with the architecture of the Temple in Jerusalem, we read this touching scene described in the Mishnah:

מדות לז, ב

לִשְׁכַּת הַגָּזִית, שָׁם הָיְתָה סַנְהֶדְרִי גְדוֹלָה שֶׁל יִשְׂרָאֵל יוֹשֶׁבֶת וְדָנָה אֶת הַכְּהֻנָּה, וְכֹהֵן שֶׁנִּמְצָא בוֹ פְסוּל, לוֹבֵשׁ שְׁחוֹרִים וּמִתְעַטֵּף שְׁחוֹרִים, וְיוֹצֵא וְהוֹלֵךְ לוֹ. וְשֶׁלֹּא נִמְצָא בוֹ פְסוּל, לוֹבֵשׁ לְבָנִים וּמִתְעַטֵּף לְבָנִים, נִכְנָס וּמְשַׁמֵּשׁ עִם אֶחָיו הַכֹּהֲנִים. וְיוֹם טוֹב הָיוּ עוֹשִׂים, שֶׁלֹּא נִמְצָא פְסוּל בְּזַרְעוֹ שֶׁל אַהֲרֹן הַכֹּהֵן, וְכָךְ הָיוּ אוֹמְרִים, בָּרוּךְ הַמָּקוֹם בָּרוּךְ הוּא, שֶׁלֹּא נִמְצָא פְסוּל בְּזַרְעוֹ שֶׁל אַהֲרֹן. וּבָרוּךְ הוּא, שֶׁבָּחַר בְּאַהֲרֹן וּבְבָנָיו לַעֲמֹד לְשָׁרֵת לִפְנֵי ה' בְּבֵית קָדְשֵׁי הַקֳּדָשִׁים:

In the chamber of hewn stone the great Sanhedrin of Israel used to sit and judge the priesthood. A priest in whom was found a disqualification used to put on black garments and wrap himself in black and leave the premises of the Temple. One in whom no disqualification was found used to put on white garments and wrap himself in white and go in and serve along with his brother priests. They used to make a feast because no blemish had been found in the seed of Aaron the priest, and they used to say: Blessed is the Omnipresent, blessed is He, for no blemish has been found in the seed of Aaron. Blessed is He who chose Aaron and his sons to stand to minister before the Lord in the Holy of Holies.

What was the “disqualification” about which the Mishnah speaks? It arose as a result of aspersions about the lineage of the Cohen, as Maimonides describes in his Mishnah Torah:

רמב’ם חל׳ ביאת המקדש, ו, יא

בֵּית דִּין הַגָּדוֹל הָיוּ יוֹשְׁבִין בְּלִשְׁכַּת הַגָּזִית. וְעִקַּר מַעֲשֵׂיהֶם הַתָּדִיר שֶׁהָיוּ יוֹשְׁבִין וְּדָנִין אֶת הַכְּהֻנָּה וּבוֹדְקִין הַכֹּהֲנִים בְּיוּחֲסִין וּבְמוּמִין. כָּל כֹּהֵן שֶׁנִּמְצָא פָּסוּל בְּיִחוּסוֹ לוֹבֵשׁ שְׁחוֹרִים וּמִתְעַטֵּף שְׁחוֹרִים וְיוֹצֵא מִן הָעֲזָרָה. וְכָל מִי שֶׁנִּמְצָא שָׁלֵם וְכָשֵׁר לוֹבֵשׁ לְבָנִים וְנִכְנָס וּמְשַׁמֵּשׁ עִם אֶחָיו הַכֹּהֲנִים

The Great Court sat in the Chamber of Hewn Stone. Their most important and most frequent task was to rule on the ancestry and disqualifications of the priests [who served in the Temple]. Any priest in whom there was a disqualification because of their ancestry would dress in black and wear a black headscarf and would leave the Courtyard. And a priest who was found to be of appropriate ancestry would dress in white and enter to serve with his fellow priests.

The decision would be made on the testimony of priest and those who knew of his lineage, as described in this Mishnah :

משנה כתובות דף כג עמוד ב 

וכן שני אנשים, זה אומר כהן אני וזה אומר כהן אני - אינן נאמנין, ובזמן שהן מעידין זה את זה - הרי אלו נאמנין; רבי יהודה אומר: אין מעלין לכהונה על פי עד אחד

Likewise in the case of two men; one says, "I am a Cohen", and the other says "I am a Cohen", they are not believed. If however they testify about one another they are believed. R. Yehuda said: we do not elevate [a person] to the status of Cohen based on the testimony of only one witness....

But what if the Cohen was mistaken about his ancestors? What if the witnesses were being paid to dupe the locals into believing the Cohen was legitimate? Is there an alternative to the methods mentioned in this Mishnah? In today’s world of genetic testing there just might be.

The Saturday Night Live Cohen 

My friend Misha Galperin, (the former CEO of the Jewish Federation of Greater Washington and  CEO of International Development at The Jewish Agency) is a Cohen. Only he didn't know it when he arrived in America from the Soviet Union.  Here's what happened, as told to me in a recent email that he kindly allowed me to share:

Five months after arriving in the US, I am sitting in the lounge of Yeshiva University's dorm watching SNL with my tutor who was teaching me Alef Bet is so I can start classes on Monday.
A skit starts with guest host Leonard Nimoy dressed as Mr. Spock - with ears - and at the end he raises his right palm in the symbolic gesture and says: "Live long and prosper!"
I turn to the tutor and ask him what this gesture means. Why?--he asks. "Because my father taught me this, and his father taught it to him before being murdered by Nazis in 1941. My father did not know what it meant, but he taught me..."

And so Misha learned that he was a Cohen from Saturday Night Live. But not all Cohanim are so lucky. (Fun fact: Leonard Nimoy ז’ל wrote about his decision to give Mr. Spock this priestly hand salute in his 1997 autobiography I Am Not Spock.)  With neither witnesses nor TV to help, is there another way to establish one's genealogy as a member of the priestly class? That's where the Cohen Gene comes in.  

The Cohen Gene

If all Cohanim are descended from Aaron, and the privilege is only transmitted from father to son, then perhaps being a Cohen can be genetically linked to a chromosome that is only passed from father to son. And there is such a chromosome. It's the Y chromosome, and all (fertile) men carry a copy that comes only from their biological father. (Quick recap: girls are XX and boys are XY. So all girls carry one X chromosome from mum and one X chromosome from dad. Boys, on the other hand, only get their X chromosome from mum, and their Y chromosome from dad. This can lead to other problems like hemophilia, which we've talked about elsewhere.) That's exactly what prompted  Karl Skorecki from the Technion, and colleagues from University College London, to analyze the Y chromosome in Cohanim and compare it to the rest of the Jewish population.  In 1997 they published a paper in Nature that looked at a special bit of the Y chromosome called YAP. Actually, they looked at 6 kinds of the YAP haplotype, (a haplotype being what geneticists call bunches of DNA sequences), and compared their frequency in Cohanim and non-Cohanim.    

Skorecki K, et al. Y Chromosomes of Jewish Priests. Nature 1997. 385:32.

Skorecki K, et al. Y Chromosomes of Jewish Priests. Nature 1997. 385:32.

As you can see highlighted, the YAP+ haplotype was found in only 1.5% of those who self-identified as Cohanim, but in over 18% of non-Cohanim.  The different frequency was found in both Ashkenazi and Sephardi Cohanim,  a result that the authors claimed was "consistent with an origin for the Jewish priesthood antedating the division of world Jewry into Ashkenazic and Sephardic communities."

These Y-chromosome haplotype differences confirm a distinct paternal geneology for Jewish priests.
— Skorecki et al. Nature 1997. 385: 32.

David Goldstein, who directs the  Center for Human Genome Variation at Duke University, also published a study on the Y-chromosome of Cohanim, using a sample that included the DNA swabbed "from the mouths of sunbathers on the beaches of Tel Aviv." Here is what Goldstein concluded:

Despite the high levels of variation, we could see a clear difference between Cohen and Israelite chromosomes. The most common chromosomes observed in the Israelites (that is, non-Cohen and non-Levite Jews) were found in only 12% of the Israelite individuals sampled. By contrast, more that half of the Cohen Y chromosomes were identical at the sites considered - that is, the majority of the self-identified Cohanim had the same type of Y chromosome. Even more remarkable, this same type of Y was found at high frequencies in both Ashkenazi (45%) and Sephardi (56%) Cohanim. (Goldstein, p.31)

Goldstein named this chromosome type the Cohen Modal Haplotype, and claimed that it showed "definitively" that Cohen status was not adopted (i.e. made up by some, eager for the benefits) but inherited.  And now things started to get really interesting. 

Dating the Original Aaron

So all, (all right, not all, but certainly most) of the approximately 500,000 Cohanim alive today seem to have originated from a common ancestor - a primordial Cohen. And just when did he live? Well, by analyzing small differences in the Cohen Modal Haplotype, and assuming that a generation time is 25 years, Goldstein et al. stated (with a confidence interval of 95%) that the origin of the priestly Y chromosome was "sometime during or shortly before the Temple period in Jewish history."

Not So Fast...

OK, a couple of things need to be noted here, before anyone claims that "genetics proves the Bible." First- as Goldstein himself notes in his book, his numbers may be off, by quite a bit:

Permit me here, after what was for me the first - and still one of the few - real thrills of discovery that punctuate the tedium and detail of science, the necessary reality check. Our results appeared to be a striking confirmation of the oral tradition. It even led to repeated claims in the press that my colleagues and I "found Aaron's Y chromosome." But although three thousand years is our best guess [as to when Primordial Cohen may have lived] the range of possible dates was and is very broad. Given our uncertainty about the ways mutations happen and how fast, we may be off by several hundred years or more in either direction. (Goldstein p.38).

Second, some later work done by Skorecki (he of the Technion 1997 Nature paper) suggests that the class of Cohanim may have had more than one common ancestor.  This work posits that there was not one primordial Cohen, but a few clans of Cohanim, from whom all later Cohanim are descended. (Or more technically stated:"...lineages characterized by the 6 Y-STRs used to define the original Cohen Modal Haplotype are associated with two divergent sub-clades...and thus cannot be assumed to represent a single recently expanding paternal lineage.")

And finally, work from Brigham Young University (and boy, those guys are really into ancestry) reminds anyone looking to do a quick Cohen DNA test to be careful.

The Cohen Modal Haplotype is observed in high frequency within the Cohanim, but also presents with significant incidence in other non-Jewish populations. The occurrence of the CMH in deeply divergent SNP haplogroups also indicates a lack of specificity of the CMH to the ancient Hebrew population. As such, inference of relation to Jewish populations for individuals or groups should be performed with caution when using the original CMH definition, as a false-positive result is likely.

 "A false positive is likely" - in other words, the test may show you are a Cohen, but really...you aren't. 

Genetic Testing - It's Not Just for Cohanim

And now that a Cohen "Gene" may have been identified, what about the rest of us non-Cohanim? Some have used genetic testing to discover a forgotten heritage or find long-lost cousins.  One rather keen family member of Polonsky rabbinic lineage (claiming in passing to be descended from King David, the Kalonymos family, and Rashi) used the presence of a "relatively rare R-M124 haplotype" on the Y chromosome to confirm a common ancestor and find a new marker that represents "Polonsky rabbinic lineage." (I confess I am jealous. My grandfather drove a black London taxi, and last time I checked, Rashi was not one of my known ancestors.) 

It's Not About Your Ancestors, It's About You

רמב"ם הלכות שמיטה ויובל פרק יג הלכות יב –יג 

ולמה לא זכה לוי בנחלת ארץ ישראל ובביזתה עם אחיו? מפני שהובדל לעבוד את יי לשרתו ולהורות דרכיו הישרים ומשפטיו הצדיקים לרבים שנאמר יורו משפטיך ליעקב ותורתך לישראל, לפיכך הובדלו מדרכי העולם לא עורכין מלחמה כשאר ישראל ולא נוחלין ולא זוכין לעצמן בכח גופן, אלא הם חיל השם שנאמר ברך יי חילו, והוא ברוך הוא זוכה להם, שנאמר: אני חלקך ונחלתך

ולא שבט לוי בלבד אלא כל איש ואיש מכל באי העולם אשר נדבה רוחו אותו והבינו מדע להבדל לעמוד לפני יי לשרתו ולעובדו לדעה את יי והלך ישר כמו שעשהו האלהים ופרק מעל צוארו עול החשבונות הרבים אשר בקשו בני האדם הרי זה נתקדש קדש קדשים. ויהיה יי חלקו ונחלתו לעולם ולעולמי עולמים ויזכה לו בעה"ז דבר המספיק לו כמו שזכה לכהנים ללוים, הרי דוד עליו השלום אומר: יי מנת חלקי וכוסי אתה תומיך גורלי

Why did the Levi'im not receive a portion in the inheritance in Israel and in the spoils of war like their brethren? Because they were set aside to serve God, to minister to Him and to instruct the masses about His just paths and righteous judgments... Therefore they were set apart from the mundane matters of the world. They do not wage war like the remainder of the Jewish people, nor do they receive an inheritance, nor do they acquire for themselves through their physical power. Instead, they are God's legion...and He provides for them...

Not only the tribe of Levi, but any human whose spirit moves him and who understands with his wisdom to set himself aside and stand before God - to serve Him and minister to Him and to know Him, proceeding justly as God made him, removing from his neck the yoke of the many mundane things which people seek - that person is sanctified like the Holy of Holies [in the Temple]. God will be his portion and heritage forever and will provide what is sufficient for him in this world, just as He provides for the Cohanim and the Levi'im...

Maimonides, in his Mishnah Torah,  reminds us about what is really important. It's not bringing a witness into town and telling everyone who your ancestors are. And it's not getting a DNA test to prove your stock. It's about searching for religious meaning in a world of materialism.  And that search is open to anyone, woman or man, Jew or not, Cohen, Levi, or even a plain old Yisrael.
