A UK man who underwent gender reassignment surgery is suing the National Health Service (NHS) over the operation after changing his mind.
The man, who is in his 30s, claims doctors did not properly consult him before the operation or warn him of the drastic outcomes the surgery poses including leaving him infertile, incontinent and feeling like a "sexual eunuch".
"The minute I woke up from surgery, I knew I had made the biggest mistake of my life," the man said on Twitter. "I have been castrated. That is the correct term.
"I cannot believe they [the NHS] were allowed to do this to me. I was not even asked if I wanted to freeze my sperm, or have kids in the future."
Campaigners say the case is the first involving alleged medical negligence in NHS transgender care, the Daily Mail reported.
The surgery happened five years ago but the man is now suing, with the case having been taken on by lawyers in Liverpool.
It will focus on whether the man was properly consulted by the gender clinic.
The man, who was 25 at the time, said he is gay and had struggled with his sexuality.
He went online and found discussions about gender dysmorphia and thought he related to them.
He joined an internet forum where he said he was urged to transition now before it was too late.
In his Twitter posts, he discusses how after the surgery he lost his sex drive, feeling in his crotch region and taking ten minutes to empty his bladder.
He claims he confronted his GP about his doubts and said there was no guidance for those who regretted the surgery.
The man has since de-transitioned from a woman to live as a man again.
