Transfems read this thread

Biological anthropologist here: TERFs are dead wrong about estrogen/testosterone not changing the skeleton. They do so much to the skeleton we had to completely reassess one of the ways we estimate the biological sex of skeletons.

So, before the advent of cross-sex hormone therapy, one of the surefire ways to ID a biologically female skeleton of a person who had borne children (this is important) was by looking for pits of parturition. These form when the estrogen surge during late pregnancy tells your pelvic ligaments to loosen up in order to fit the baby’s massive head through the birth canal. Your pelvis starts to s There’s hypothetically only one normally occurring biological reason for a body to give that signal, and since you have to be nominally XX (or some variant of that where you can still carry a pregnancy to term), it was a pretty solid shorthand for sex!

Until we started looking for these things outside of female skeletons, and surprise! “Male” skeletons can have them too! Sometimes these are chromosomal variants, sometimes they’re men with a high estrogen or estrogen-esque hormonal component, and in the modern era? Sometimes these are trans women whose skeletons have undergone hormonal changes due to taking estrogen.

And then there’s testosterone. You know what that does, right. It makes it easier to build muscle. But what THAT does is put new and interesting stresses and pressures on the bones, making them more rugged and in line with the skeletal structure we see in people who have had high testosterone their entire lives. We don’t just see this in trans men- we see this in older cis women too. Once your estrogen production tanks after menopause, we see what we call masculinization of the face, where the features get more rugged and robust as tissue production changes. These changes don’t happen overnight, and we don’t have good data (yet) but my guess is that when we start looking at the skeletal remains of trans men who took T throughout their adult lives, their skulls are gonna look pretty damn masculine.

Now, hormone therapy isn’t going to change every aspect of your skeleton. Estrogen in particular doesn’t do too much to the cranial bones. Your skeletal height and limb length are unlikely to change. Things like the size and shape of the pelvic inlet, the sciatic notch, and other features that are used in sex estimation, are also unlikely to change. Professional anthropological sex estimation is a complex calculus where you look at many, many features of the skeleton to make the best possible estimation of what sex the person was. It has nothing to do with gender or gender presentation. It simply tells us the end result of your hormonal composition during life. So long as you’re taking hormones regularly for a while and giving your body a chance to change and grow, your skeleton WILL undergo changes based on your hormone levels.

Hey, one anth to another: I'd love to read some of this literature, do you have any reccs? Cause I always figured that hormones would change things like bone density and possibly some of the shape, but after fusing and ossification they cant change things like the sciatic notch and the bowl shape of the pelvis and whatnot. Because I know that in grad school we did learn about the pits of partirition but as like an outdated thing that isn't very useful for sex ID anymore (if anyone's wondering, these are the source of that "pregnancy leaves notches on your pelvis" post that was going around tumblr a few years back. It isn't true.). Tho I'd love to see a study on the hands thing the op mentioned. Like I know a lot about the skeleton at this point and I'd love to know how that happened. Was it remodeling? Did the hormones somehow "reactivate" the ephyphesys? Change the bone ossification? Or was it all soft tissue? Because we do know that males and females have different proportions to their fingers vs palms (that's how the handprint paintings in caves were IDd as done by women.), but is it bone or soft tissue? Idk man it's just really interesting.

[kaijutegu]

Yeah! Fair warning, a lot of these papers use terms that the trans community no longer sees as appropriate. The language standards that the medical community uses are not the same as the trans community at large (I’m sure any trans person can tell you that!) so you’ll see terms like “transsexual” a lot.

The TL:DR from all of this: there is good evidence for skeletal changes during adult-initiated HRT. We know that these changes occur, but there isn’t a whole lot of literature about exactly what occurs. Many of these changes are minute and you may not see them in a living trans human, but are more discernible in a skeleton. We need to study this more.

Ok, so we’ve identified that there ARE bone changes. How does muscle affect bone structure?

Explains the bone/muscle relationship in typical cis men and typical cis women: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3189615/ (Note: by typical, we mean that their hormones are generally within the range that’s expected for their chromosomal composition.)

Some interesting reads on the relationship between sex hormones and cartilage

Estrogen and osteoarthritis (aka cartilage loss): https://www.mdpi.com/1422-0067/23/5/2767/htm

More sex hormones and osteoarthritis: https://faseb.onlinelibrary.wiley.com/doi/abs/10.1096/fasebj.27.1_supplement.1053.15

Generally speaking, HRT isn’t going to do too much to the cartilage. If you think your nose looks different, it’s probably because you’re seeing it in a new context since the fat deposits on your face rearrange themselves. They’re very close to the surface, after all.

Identifying transgender people within archaeology

https://miami.pure.elsevier.com/en/publications/the-fallacy-of-the-transgender-skeleton (good read on how human sexual dimorphism... isn’t. The spectrum of traits overlaps too much.)

surgery piece: https://www.sciencedirect.com/science/article/pii/S0379073820300827?casa_token=jy_vbV7_fXkAAAAA:nz2d-xCUT-JoYACam3CDliKmto1UFkB8-ft837QzSpjLZJ0uiH5DHNSH7M_fG_b5XWsln3yZZKk

As for the mechanism, it’s a combination of remodeling and changes in bone density. The bones don’t unfuse, so you’re basically stuck with the same structure, just with different sizes and densities. This is more notable in trans men- they can lose some height from bone density loss if they’re not careful. It’s usually not a lot and isn’t as noticeable in living people as it is in skeletons, because there’s a lot more tissue to you than just bone! It’s the same mechanism that happens in cis women with osteoporosis. Fortunately, most endocrinologists take that into consideration these days.

Right now, most of the research on skeletal changes is focusing on FFS because it’s much more visible and dramatic. There’s a lot of reasons we don’t really understand everything that HRT does to the skeleton- we know a lot of it, but not everything- and how any of it shows up in the archaeological record. One of them is that HRT is relatively new and we don’t have the representation in skeletal collections. Another is that most of our standards are written based on studying white people, and while you can’t truly identify race from a skeleton, you can associate a skeleton with certain genetic groups based on suites of traits. By only including white skeletons in a study, you miss out on a TON of variation.

I know this is a little disjointed, but I think it’ll help as a starting place for people interested in doing more research on the relationship between HRT and the human skeleton and how we can see some of these changes in the archaeological or forensic context!

[catboybiologist]

Amazing list of resources, and as a biologist in training imma take a dive into these.

But a friendly reminder: the key ingredient of HRT is PATIENCE. I've already read a lot of studies, and most seem inconclusive, but all agree on one thing: time on HRT (with appropriate levels) supercedes the majority of other factors involved with feminization/masculinization. Don't let someone tell you you're "done" at one year, two years, five years.... this is lifelong. Your body will adapt to the hormones it currently has at the age it is. Let it do that, and give it the time to do so.

Fossil diatoms retain their intricately patterned glassy silica shell cases. Called frustules, these may be either rounded or elongated. Living diatoms are single-celled, algae-like protists. They make up much of the plankton in the marine and freshwater food chains. Their shells accumulate by the millions on the seafloor, eventually fossilizing to form a siliceous sedimentary rock called diatomite.

"Do you ever dream of land?" The whale asks the tuna.

"No." Says the tuna, "Do you?"

"I have never seen it." Says the whale, "but deep in my body, I remember it."

"Why do you care," says the tuna, "if you will never see it."

"There are bones in my body built to walk through the forests and the mountains." Says the whale.

"They will disappear." Says the tuna, "one day, your body will forget the forests and the mountains."

"Maybe I don't want to forget," Says the whale, "The forests were once my home."

"I have seen the forests." Whispers the salmon, almost to itself.

"Tell me what you have seen," says the whale.

"The forests spawned me." Says the salmon. "They sent me to the ocean to grow. When I am fat with the bounty of the ocean, I will bring it home."

"Why would the forests seek the bounty of the oceans?" Asks the whale. "They have bounty of their own."

"You forget," says the salmon, "That the oceans were once their home."

[squaresaw]

So last month I got hit by a car and died right. Which I didn't initially realize until I watched some guy haul my body into his pickup and drive off. Which, being that it's deep in rural Michigan, I assume means my body will make some venison jerky and maybe some wall decoration, and I'll be resigned to being one of hundreds of deer ghosts floating around Saginaw, which is w/e. But then I find out the guy works at a taxidermy shop or something, and he's actually pretty good at stuffing and mounting deer carcasses, which I come to find out when I find myself face to face with my old body in the shop window. So naturally, I figure since ghosts need to possess something to interact with the living world and etc etc etc the most logical thing to do is to possess my own body, since it's basically a statue of myself. And a little surprisingly, it actually fits like a glove. Like, since it's my body, it feels like stepping right back into place. So I get out of town and back to my herd, eventually. And that's where the trouble starts coming into it, because after I get settled again, I don't know how to explain to everyone else what feels so weird. Like since I can move my body and do everything I used to do, it's functionally the same, like nothing happened. Or it SHOULD be, so I don't know how to explain how it's NOT. But it's just hard to explain it to someone who's never been hit by a truck I guess
