I read an account on-line, I can't find it now, but it was someone who fully transitioned from male to female and the excruciating pain and agony he was now dealing with that nobody ever told him about. Unable to walk, unable to sit, stitches, can't urinate, infections, and on and on. He was deeply depressed and regretted getting his dick chopped off almost immediately. When you go this far, there's no transitioning back.
The Hippocratic Oath states "first do no harm" and any doctor who would perform such a surgery needs to be stripped of their ability to practice medicine.
