Properly understood, a person cannot change his or her sexual identity. For persons not suffering the disorders mentioned above (e.g., hermaphroditism [congenital adrenal hyperplasia (a species of which is anrdogen insensitivity syndrome), mosaicism, chimerism, or some other congenital cause of mixed sexual identity[) a person is either male or female. A person is the unity of soul and body, and ‘soul’ should be understood not as an immaterial self, but as that which makes the body be what it is, namely, a human person. We are either male or female persons, and nothing can change that. A person can mutilate his or her genitals, but cannot change his or her sex. Changing one’s sex is fundamentally impossible; these procedures are fundamentally acts of mutilation…Such operations should not be thought of as changing a person’s sex, but rather confirming what is originally ambiguous.
