Fatwas on Gender Change

Q1271. Some people have the appearance of men. They have female psychological and sexual tendencies though. If they do not undergo the operation of sex change, they might commit sins insofar as their sexual behavior is concerned. Is it permissible for them to undergo such an operation?
A: There is no harm in undergoing the said operation if the end result would be determining of the true sex of the person provided that it does not lead to the commission of any ḥarām act or a vile consequence.

Q1272: What is the ruling in the matter of undergoing an operation for a hermaphrodite person to become either man or woman?
A: There is no objection to it in itself provided that one avoids ḥarām preliminary steps.
