True transsexuals could be of either sex. The term 'gender dysphoria syndrome' was then adopted to designate the presence of a gender problem in either sex until psychiatry developed an official nomenclature. The diagnosis of Transsexualism was introduced in the DSM-III in 1980 for gender dysphoric individuals who demonstrated at least two years of continuous interest in removing their sexual anatomy and transforming their bodies and social roles. These diagnostic terms were ignored by the media who used the term transsexual for any person who wanted to change or had changed sex. In 1994, the DSM-IV committee replaced the diagnosis of Transsexualism with Gender Identity Disorder.
Some professionals informally use the term to refer to any person with any type of gender problem.
