I choose "other'. It is a means of controlling one own ability to reproduce. And in some cases it is a decision that is make for another person. In the 50's, the mentally ill were forced sterilized.
I never went thru the procedure myself, as all my exes choice not to have any more children. But I might have been the cause, because of my GID. But who knows.
I am looking forward to losing those pesky little T factories.
