This is a fascinating little video. They call it a documentary, but I think that's a stretch. It's about three people that regret having transgender surgery. I feel soooo sorry for them!
Here's what stood out to me. Two of them have transitioned back into being men. Those same two are Christians. It wasn't clear if they came to Christianity before or after the transition, but I suspect they were raised Christians, abandoned it to become transgender and then embraced it to transition back.
In any case, if this is a subject that interests you, have a watch. It's about 20 minutes long. I will reiterate that I don't buy the whole documentary thing. These three individuals all think it's impossible to change your sex. I'm not advocating that. I'm just sharing a human interest story.
Oh, and it's by Russians, so beware of being influenced.
