Yeah in this context it's for transgender HRT. I'll probably make an update to fix some typos after I've compiled a few of them (the fact that one link in the first passage ends in a period and the other doesn't has been bothering me since I put this live)
As for Miéville I've only read a small portion of Perdido Street Station; I wasn't trying to emulate him specifically but that is sort of the general genre I was going for.
