This preliminary study describes a case of a male patient who developed gynaecomastia and sexual difficulties whilst taking risperidone for chronic paranoid schizophrenia. Laboratory tests showed raised prolactin levels and depressed testosterone levels which were reversed on cessation of medication. A small study was subsequently conducted on male psychotic patients to compare the prolactogenic effects of risperidone (n = 14) with traditional antipsychotic medication (n = 15). The results showed a greater but non- significant prolactogenic effect of risperidone.
