1) Spiro is not a hormone, it's a hormone blocker. Testosterone is a dominant hormone, so it will counteract any estrogen in the system. To femenize, trans women that still have their testes have to take Spiro to block the testosterone they produce. After GRS or an orchi, only Estrogen is needed.
2) Not as far as I've noticed.
3) It depends. If our medicine is properly attuned, they look like any other girls', but maybe with lower testosterone.
