The medical achievement of transsexual surgery requires a reconsideration of the relationship between ethical theory and moral practice. Individuals who are anatomical of one sex but believe themselves to be of the opposite gender are considered transsexual. Such individuals do not doubt their anatomical identity. They are certain it is the wrong one, and as a result, they want their anatomy to fit their gender identity. Their condition can become acutely painful, resulting in significant sadness, life disruption, and even suicidal tendencies. Transsexual surgery refers to the physical reconstruction of a person who is biological of one sex but claims to be psychological of the other. There are treatments available to create genitalia that is both cosmetically satisfactory and functional.
