Before puberty there is actually very little difference between the sexes in terms of bone structure. It isn't til puberty does that change. There is an age when the end plates of the bones fuse and changes cannot be made. If I remember correctly it's about 20-ish. Before that time, cross hormone therapy can alter bone structure but what is there is there. For example, I started HRT at age 30. My bones will not change shape. If I started at 15-16 would be a different story.

Appreciate the reply. Yeah if a kiddo is going through the process pre-puberty that's a very different thing. I also agree with the "wait period" if someone has recently transitioned. There certainly is some middle ground in the conversation and that's just where I want to be discussing. I don't think this is a binary decision of in or out. I think there's some ground rules that can be applied to try and be accommodating to everyone participating.
