The Hospital seems to be bugged as it does not seem that you can interact with the Hormone Specialist unless your character has a femininity positive 25-49%, if it is any lower or higher it just doesn't work.
The bug can be bypassed by using the heart ring wearable, but that is where you will run into the second bug. If you try to get either testosterone treatments, the scene will play out but no money will be taken from the player and there is no difference in player's stats afterwards either. AKA, nothing happens.
