Ah, well, to be clear a human being cannot survive without a growth hormone production so you get to pick Testosterone or Estrogen, and if you cut off your balls or your uterus then you'll need a permanent medical provider sourcing it to you or else you will get sick and weak and die. Sadly, many post operation trans are at risk of this torture at the hands of conservative political parties the world over, as the care is being outlawed in some places.

Sorry, I just felt like "too much testosterone" was a little misleading. Less of a necessary hormone is rarely a solution to any problem without a replacement.
