[Clinical picture and development of transsexualism].

The results of a clinical study of 33 patients with transsexualism (TS) have shown that TS is a pathological state of the person whose essence lies in the polar discrepancy of the biological sex with the forming psychic sex. It can be described as a true inversion of sexual identification and orientation. The formation of TS has been found to have a regular pattern. Four types of TS development have been identified. It has been shown that TS predisposes toward a high risk of suicidal behavior. It is suggested that the development of TS may be evaluated as autochthonous.
