The gender definition law states that a person gender will be determined by his birth certificate and less there is sufficient medical evidence DNA and Gene testing to prove that the person should become another gender.
at which time the birth certificate will be reissued under the new sex. that's going to put an end to a lot of people changing sex just because they feel uncomfortable with who they are.
Do you think that a person should be able to change their sex just because they want to? Without medical evidence to support that they actually are another gender with the wrong organs.
