Being transgender is not a mental disorder. It cannot be "cured" with treatment. Transgender people experience a persistent disconnect between their assigned sex and their internal sense of who they are, and professionals refer to this disconnect as gender dysphoria because it can cause pain and distress in the lives of transgender people.
In 2012 it was announced that a new version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) would replace the term "gender identity disorder" with the more neutral term "gender dysphoria."
Sex and gender are two different concepts. A person's sex refers to his or her biological status as either male or female. The determination of a person's sex depends primarily on various physical characteristics, including chromosomes, reproductive anatomy and sex hormones.
Gender is a societal construct that deals with the expected behaviours, roles and activities typically associated with the different sexes.Gender roles, which vary across cultures, influence how people act and feel about themselves.
Sexual orientation is different from gender identity. Sexual orientation is a person's physical, emotional or romantic attraction to another person, while gender identity is about one's own sense of self. Transgender people may be straight, lesbian, gay or bisexual. For example, a person born with male genitalia may transition to being female but may be attracted to females. In this case, the person may identify as lesbian even though she was born with male genitalia.
