Testosterone can't realistically cause a person over the age of 20-22 to grow any (except maybe sideways). I have heard all the reasons why. I agree with that premise.
However, I have had two medical staff (a nurse and phlebotomist) when I give them my height say that I seem taller than that. And with the second one, since he asked me, "How tall do you like to say you are?" instead of "How tall are you?" I fudged it an extra inch, and yes, he still said I seem taller than that. Doesn't make it so, but it sure makes me feel better about my size.
Maybe my binder is giving me better posture. Maybe I carry myself differently now/on T. Maybe my shoes have thicker soles. Maybe the people in this city are shorter on average and that skews their perspective.
Whatever it is, the reaction makes me feel a lot better about myself.
For the record, I'm between 5' 1 1/2" and 5' 2".
did they just ask, or did they actually measure your height? it's not unheard of to still be growing a little bit into your early 20s. i went up an inch and a shoe size around that age. of course, the other stuff you mentioned is also plausible. could be both...
They just asked. I'm 37 - too old for a growth spurt. But it still feels nice to seem taller to other people.
I gained an inch at 26 due to postural changes after starting to transition. So it could be that.
