[Sexual deviations and perversions in schizophrenia, psychopathies and oligophrenia in male adolescents].

A study conducted in a mental hospital involved 157 male adolescents (aged 14-17 years) with psychopathy (n = 42), oligophrenia (n = 49), and schizophrenia (n = 66) who displayed some sexual deviations. Homosexual manifestations were found to be the most frequent form of sexual deviations (61%). Other forms included sadomasochistic actions, heterosexual aggression, sexual claims to relatives, exhibitionism, etc. The mechanisms of the development of deviant sexual behaviour differed in the framework of the nosology and type of deviations.
