I had a brain injury when I was 12 that knocked my testosterone levels way down.
In my 20s this was discovered and I went on testosterone replacement. My hands are still the same size as my mom’s. My feet didn’t get back to the size they were before the accident. I didn’t regain the height I lost. God only knows what it did to my brain.
Maybe if you’re only on them a little bit you’d be fine, but the whole concept is bad. My wife fainted when she got her first period. Why? She didn’t want to be a woman. She was a tomboy. It turns out that the flood of sex hormones during puberty can actually make you feel like a woman/man, which should surprise no one. To block that from happening and potentially effectively treating the dysphoria is madness.
