First and foremost, voice. Before your voice settles, which takes about 2 years, you deal with cracking. A lot. If you go off before the cracking stops, you will have cracking forever. Voice changes won't go back, but can be trained like mtf in SOME cases. Second, bottom growth. Will not go back. Body Hair changes. These may or may not go back. Hair loss can be permanent. Heavy hair growth including on the face can be permanent. It might thin out, it might not. Facial mechanization. It may go back it may not. Fat and muscle redistribution. It will probably partially go back but its a slow process and theres some changes, especially when you're young, that won't. Any changes to the skeleton, such as height or hand size, shoulder width, are pretty much permanent but they're not super common in the first place. Thats all I can think of, and I've been researching testosterone since I was 15 and on it for 2 years (not detransing, just educating myself on the community and found your post)

It stems from the fact that people who were trans in the past and needed to transition were gatekept for reasons such as being attracted to the "wrong" sex, being ugly (yes if you were considered unattractive as a woman you could be denied estrogen), being depressed even if that was caused by needing to transition, or just if the doctor didnt like you. The gatekeeping was so strict that it was just impossible for some people who really could have benefited from transition. So when the tides changed, the community pushed for the informed consent model (in america mostly) because they believe that gatekeeping has the potential to be abused and harm people who really need transition, and they believe adults should be capable of making their own decisions without needing to jump through hoops. I went through informed consent because I cannot afford not to, it's my only means of accessing my testosterone and I can't imagine how miserable I'd be without it (I have a pretty good idea though, given the place I was in before vs where I am now) But I do understand now, at 20, that IC maybe isnt the best model, at least not for everyone. There needs to be a balance between an hrt free for all and a system so difficult it makes people wish they were dead, but with the current american healthcare system being so expensive, IC is just some peoples only way to get there. I do agree that within the community there needs to be a larger push for medical transition being the last step you take, after you've exhausted other ways of trying to treat dysphoria, and you need to make sure what you're feeling is not rooted in trauma or dysmorphia before you medically transition. It isnt a curall and needs to stop being treated as such.

I feel that. A balance, keep your mind in check while you go through a huge life altering medical process, that works without making things hard. I think alternatives to transition should also be explored regularly, before radical body alteration. There need to be more resources for that

Hormones are pretty important to many functions in your body, i would 100% talk to several doctors, endocrinologists, etc before making the choice. I dont have much education on the subject, but I did study forensic anthropology and did specific research into some resources about the effect of hormone on bones. Hormones are responsible for creating osteoplasts and osteoblasts, essentially the things that heal your bones when they break. Without hormones for a long period of time your bone density is likely to go down which can lead to osteoporosis, which means they can break easier. I'd be very cautious.

I've noticed this quite a bit myself, the everpresent idea that testosterone is reversable or not that big of a deal, or that microdosing will lessen the effects. The misinformation of it all kills me, and when I do try to educate, I've been repeatedly shut down by MY OWN "community,". Like telling someone testosterone isnt something to be taken lightly is a bad thing smh
