Sexual Dimorphism and Gender

Imagine walking down the hall and encountering this argument:


BOB: I don't know what you folks are going on about. Look, there are two sexes, male and female. If you're female, you're a woman. If you're male, you're a man.

KIM: You're wrong. Sex isn't binary. People aren't just male or female. There are intersex people. That proves that gender is a lot more complicated than what you just said. There are a lot of different genders, not just two!


If I were the one walking down the hall and hearing this, I would want to tell them that they're both wrong. First off, sex isn't gender. Sex is your physical morphology. Gender is identity and role, all that social stuff.

If you were a person who basically agreed with Bob, you most likely wouldn't be here reading my blog. So I'm not going to waste your time and mine developing the counterarguments to Bob that you've already heard and can make as well as I can.

But to Kim, I would want to say: "We don't need it to be true that there are more than two sexes in order for our nonbinary gender identities to be valid. You shouldn't even bring up physical biological sex in this argument. It just confuses the issue. I've got all the parts that caused my mom's obstetrician to mark down that I was a male baby. I'm not remotely intersex. My body fits the textbook description of male. I'm femme, though. I'm all gal. I was never into that boy stuff, I always knew I was one of the girls. Saying that the plurality of binary physical sexes is what makes nonconforming gender identities valid implies that our gender identity isn't legit otherwise".



I do get crossways with transgender activists and nonbinary activists over this physical-body stuff on occasion. They'll sometimes respond to what I said about having conventional textbook-description male parts and saying I'm a male girl or a male femme with a burst of defensive anger: "Excuse me but having a penis doesn't make you male. Biological sex IS A MYTH! You shouldn't go around saying that having your set of physical parts makes you male because then you're saying that if I have a penis that makes me male, and honey don't start that shit with me, I have never been male. I was mistakenly assigned male at birth!"

But no, biological sex is not a myth. The notion that biological sex defines gender, that is a myth. The notion that everyone is supposed to be either male or female, and that anyone who isn't is an embarrassment who needs to be corrected surgically as soon as possible, that is a myth. But it is indeed one's physical bits that defines one's sex. So we need to discuss sexual physiology, even though it's not determinant of a person's gender identity. Or maybe precisely because it is not determinant of a person's gender identity.



Despite the existence of real intersex people, we are a sexually dimorphic species. In general, like most complex animal life forms, we're either male or we're female. Our species is not a species that reproduces through the interaction of three, five, or thirty-seven different sexes doing a wide variety of reproductive behaviors. It's a species that reproduces though the interaction of two fundamental body designs, and intersex people who reproduce don't really modify that fact. Nobody alive today or at any time in recorded human history gestated in an organ that was not a uterus. Nobody ever got their chromosomes from gametes that were neither sperm nor ova. There isn't a sex that is neither male nor female that produces sex chromosomes that are Z or W instead of being X or Y and which encode the sexual possibility of developing into a specific body that isn't male or female. You could write a great science fiction tale about a species that was like that, but that's a fictional and imaginary idea of intersex, not a real one. And since real intersex people exist, we should pay real attention to them for a minute instead of just using them as a rhetorical argument about how human biological sex is nonbinary.


Some intersex people are CAH (i.e, they have Congenital Adrenal Hyperplasia). These are people whose sex-encoding genes are just like those of most people whose bodies present as female, but where a variation in the adrenal gland's behavior causes them to have a lot of the type of hormones that make a person's body take on male attributes. This adrenal gland behavior is caused by their genes, but not the ones on their sex chromosomes, so the biological roulette of what sperm's codes went into the egg isn't causing this. At birth, CAH people's bodies may be designated male. More problematic, their bodies are often recognized as intersex and the doctors reach for their sharp scalpels and whack away the offending phallic clitoris. This -- and not the rhetorical flourish of discarding the entire notion that biological sex exists at all -- is probably the most significant political concern of real-life intersex activists. To get doctors to quit doing this. To let CAH babies make their own decisions about their own bodies when they are old enough to do so.

Other intersex people are CAIS (i.e., they have Complete Androgen Insensitivity Syndrome). These are people whose sex-encoding genes are just like those of most people whose bodies present as male, but other genes of theirs (not on their sex chromosomes but elsewhere in their genetic code) make their body unresponsive to the hormones that make the body take on male structures. So their bodies at the time of their birth will nearly always be designated female. Unlike the CAH people, they aren't at high risk for being carved up by surgeons when they're still infants, but at puberty they won't get periods; the fact that they have undescended testes (usually) instead of ovaries may be discovered, and even though they are old enough to voice an opinion, doctors sometimes pick up those sharp knives and cut out their testes without asking. Or the doctors may mislead the CAIS patient (and their parents, who typically have medical authority) about the risks and consequences. This is another of the intersex activists' political concerns, fully informed consent for CAIS intersex people.


CAH and CAIS intersex people can generally reproduce. But despite being intersex, the physical architecture and the chromosomal arrangement with which they participate is going to follow either a male textbook description or a female textbook description.

But what about intersex people who are neither XX nor XY at the genetic level?

The Turner pattern, where a person has a single X instead of two, also called XO configuration, creates a female-structured body with some modified shapes (shorter, broader chest, some differences in the face, and so on). They are often infertile. They don't tend to be designated anything other than female at the time of birth. A few do not have a uterus or ovaries. If they are able to reproduce, they do so with the structures and capabilities of female people, and their genetic contributions will work within the sexually dimorphic reproductive pattern like those of female people.

The Klinefelter pattern, where a person has an XXY configuration, creates a male-structured body with some mildly modified shapes. They are almost always designated male at birth. At puberty they may not develop secondary sex characteristics, or may develop them less strongly than other males.

There is an XYY pattern as well, the Jacobs pattern. They are almost always designated male at birth. There are some mild differences in body shape but it often goes undetected.

There are also mosaic situations, such as XO/XY where some of a person's cells have XO and others have XY. A person with this configuration may be born with a body that presents as typical female, typical male, or ambiguously intersex. Or even more rarely, there is XX/XY, the closest to the legend of hermaphrodite, wherein, depending on which cells in which part of the body have developed according to which structural patterns, may result in both ovaries AND testes developing. There is the theoretical possibility that a person could produce both viable sperm and viable ova and could therefore participate reproductively as a source of sperm and/or as the person providing the egg, but there's no case of this on record.

I haven't said anything about the political intersex considerations for people with these forms of intersex because I'm less familiar with them. Self-determination, certainly. The right to choose whether to receive supplemental hormones (or hormone blockers), the right to fully-informed consent not muddled by the outdated attitude that any variation needs to be hidden and "fixed", the attitude that difference is shameful and inferior and wrong.


The takeaway from intersex awareness is not that sexual dimorphism is an evil lie that supports the gender binary and the "anatomy is destiny" conservative belief systems, but that people who vary should have the right to make their own decisions about their own bodies, and should be regarded as normal variations, not sick pathologies.
