Honestly depends on your state and institution and overall is incredibly vibes based. Like depending on the state the system might be on the hook to allow a bottom surgery… But whether or not you “fit the requirements” won’t be determined until after the fact. If the people running the system are anti-trans you will be lucky as a post op trans person to be allowed horomones at all. There’s documented situations of trans women basically entering a sort of menopausal state and having their horomones witheld indefinitely by wardens basically because there isn’t a lot of oversight or consequences for doing so.

It’s also taken as kind of a given that sexual assault of trans people is just a thing that is accepted as a cost of doing business. This is something actually that Trans men stuck in women’s prisons also report as a common experience. The system as it is designed raises the risk for a lot of trans women in prisons seeking transition because if you get bottom surgery and you are denied transfer your sexual assault chances skyrocket to “expectedly matter of course” .

So while the 15 people who have made it all are fully medically transitioned, fully sterilized and been on hrt for longer than the required time for athletes the answer regarding requirements is generally “at the pleasure of the administrations in question which is most often not at all”
