This sounds very sensible in the focus on psychological approaches. Caution on social transition is good.
What about inviting kids for follow up who have already taken PBs via Tavi over the past few years? That way they can see what the long term outcomes have been (after all Tavi know what they prescribed and when) without doing lots more research and needing to put more kids on PBs experimentally?
Have they also changed the requirement that PBs must be taken before cross sex hormones can be given? What about the kids already on that pathway currently on PBs, will that be stopped immediately?
