You actually cannot survive without at least one functional adrenal gland without taking supplements for the rest of your life
And some folks need to live like that, because their adrenal glands would not "behave" as they wish. Some such people are undoubtedly children.
At some point there will be technology that allows a new way to regulate that system, and for such people to help it behave. Having the ability to provide a direct handle, and denying this direct handle, in the immediate and current knowledge that a direct handle has distinct and well understood survival benefits and costs, creates an ethical obligation for this to be on offer in acceptance of costs.
There can be safety limitations imposed which require some conscious effort to overcome, but even then, there is the reality of the situation where someone needs a lot of adrenaline at once, knows it will kill them, and has every reason and right to do it anyway.
The only reason that we don't already have that, usually, is because many people would make decisions that save their loved ones rather than themselves, and this is not necessarily or directly contributive to direct genetic descendants being produced. It also provides a mechanism that allows for immediate, violent self-destruction, which assumes the former, but with the whole "violently enabled and already past acceptance of immediate death" aspect.
I think I'm some respects knowing that any given adult human could physically rip any other adult human practically in half at the expense of their own life, it would contribute a good deal more polity in society.
But you're the one that got us on a derail about whether or not other hormones deserve personal oversight.
Frankly, that is all unexplored territory legally speaking. We can theorycraft on how we expect it to turn out, but the reality is that it would be an unmitigated shit show with a whole new target for the ire of those who cleave to the naturalistic fallacy: the "sin" of having "mods" or whatever name ends up being attached.
The name is unimportant.
With testosterone and estrogen, we know the effects of exposure. We have seen those effects, and the effects of having control over them, and those effects are broadly positive.
I disagree entirely. And if we want to suppress androgens today, there are andrigen blockers.
So you disagree with what? The existence of people who need to get their adrenal glands removed because they create a dangerous physiological condition? How else beyond being born without adrenal glands would we know that supplementation is required in their absence?
How do you disagree with the position that those who are forced to lack them through the dangers they create for the individual or the sheer lack as an accident of physiology, that they deserve to be able to install such that will not kill them?
And at what point after that can you justify depriving them of a handle onto some control over that?
And from there, once we have offered it to some, where do you justify offering it ONLY to those few?
The fact is, human beings DO normally have some limited control, and some so much control that they could probably kill themselves that way. You would be taking the philosophical position that them being born without is justification for them forever being deprived of available human experience, even should they seek it.
Flat disagreement doesn't create any philosophical leverage for rejection of any of this.
As to androgens, the fact is that sometimes people want to choose how they will be medicated.
Personally, I would rather be able to go anywhere in the world, any time in the future or even the past, though the latter is the stuff of mere stories, and not need a medication that I probably can't get there to feel at least some semblance of "normal".
I would rather let my bones rot for a few years while I explore the world, than for those years be forced to go back to the way I was.
Do you actually understand how much anxiety is produced by the constant worry that something that makes your body and mind tolerable to live in will suddenly be unavailable because of a change in "where" or "when"?
And "when" for me could easily be "tomorrow", because it certainly was on some particular "yesterday".
At that point, the only way to force me back onto androgens would be to tie me down and inject me forcibly with them.
They can use whatever sophistry at that point to deny I am a "man" or to deny I am a "woman" but I never asked to be either of those things, not really. I will undeniably be what I sought to be: a eunuch.
It's the sort of decision that has to be made on a cost basis.
