Yes, it does. However, the science also shows that post-puberty testosterone and estrogen regimens are also effective at shifting the body. Estrogen for a trans-woman diminishes musculature (and triggers breast growth, etc.). Testosterone for a trans-man increases muscle mass.
If you trace the discussion, Pix - my position was "we don't know" and your position was "zero effect." I was pointing out that the lack of evidence means your position is not defensible. Lack of evidence is actually specifically why I hold the position "we don't know." I'm not shifting burden of proof, and I did not make a "positive claim," (unless "we don't know" is a positive claim). I'm pointing out that you do not have evidence to support the "zero effect" claim.
