It's hard to say... What part of transition would I have to cease? What part would cause me to die? If I was unable to take hormones because of some medical condition, I would still transition without them. I obviously would not be quite as feminine, but I'd do what I could. There are lots of aspects of transition that don't require medical intervention. Particularly, with enough practice and dedication, you can make some pretty miraculous changes to your voice. I've heard many amazing vocal transformations without resorting to surgical methods, although it is quite a lot of work sometimes to achieve it. Voice and mannerisms go a long way towards being read as your target gender. Then there are the changes to appearance you can make without medical aid, as well, such as growing your hair out/purchasing a good wig, learning to apply makeup and what works for you, clothes, etc.
