Not really, just because you feel like you're female, doesn't mean you are female. Transitioning doesn't make them female, it only makes them approximate the female form, which is why they kill themselves at just as high a rate as before transitioning. What they actually need is therapy that will help them learn to accept that they aren't female, and can never become female, even if it's not possible to stop them from wanting to be female. This is not a "pray away the gay" type scenario, this is helping fix a delusion (clinically speaking, not colloquially) they have.
