noun. a gender identity disorder involving a continued feeling of discomfort and inappropriateness correlating to one's anatomical gender, with a continued desire to be free of one's genitalia and to live as a member of the other gender. With regard to the DSM-IV-TR, the diagnosis is employable only if the condition isn't because of another cognitive disorder, like schizophrenia, and isn't correlated with intersexuality or genetic defect. A multitude of transsexuals feel that they belong to the opposite gender and are, in some way, trapped inside the wrong body. Thus, they desire to modify their gender via surgical and hormonal methods.
