There's never enough information in journal articles! One can usually 
email the corresponding author to ask questions, I've almost always been 
answered when I've done so.

What stood out to me is that this transwoman already had Tanner stage V 
breasts after starting feminizing hormones in her mid 20's. I've read 
elsewhere that Tanner stage III is more common development for 
transwomen who start feminizing hormones after puberty. It's pretty 
fabulous how flexible the human body is.

When we are speaking to individuals, I absolutely agree we should use 
their preferred pronouns, and not take for granted that everyone is 
cis-gendered. When we are discussing something scientifically, it's 
important to be precise to avoid ambiguity and build knowledge that will 
help us assist other families in future. I use transwoman in this post 
in that spirit.
