Can it turn you into a fully functioning opposite sex body and flip your sex chromosomes? Yes, I'm aware that you can cosmetically alter your body to appear like the opposite sex, but you just end up just becoming a non-reproductive member of society. You may feel better mentally, but your body will forever be strained by how invasive those procedures are. That real physical discomfort will be worse than the dysphoria you felt before.

It should only be done by healthy, consenting adults who understand that it is purely cosmetic.
