Since there’s a lot of talk about TRT on this forum, I found this interesting 2005 piece about a 33 year-old man in England who has Kallman’s Syndrome. He had the testosterone levels of a child, but was given testosterone to induce puberty, at 33 years of age.
I know that testosterone levels often correspond with facial and body appearance, i.e. those w/ high-T have strong jaws, large brows, heavy facial hair, etc. I’ve wondered what the testosterone levels of someone like Leonardo Di Caprio would be, b/c he seems to have the most childlike face I’ve ever seen on a 30+ year old man.
