Abstract BACKGROUND: The novel antipsychotic medications offer a more favorable extrapyramidal side effect profile than conventional agents. It is uncertain that the novel antipsychotics have a benefit in terms of sexual side effects. METHODS: We prospectively administered a survey of sexual functioning to 25 male patients with DSM-IV schizophrenia, taking conventional and novel antipsychotics. Contrasts were made between three treatment groups: clozapine (CLOZ), risperidone (RIS), and a combined haloperidol/fluphenazine (HAL/FLU) group. RESULTS: A decrease in overall sexual functioning was reported in all medication groups (40-71\%). The majority of subjects taking RIS or HAL/FLU reported a decline in one or more aspects of sexual functioning. Examining specific aspects of sexual functioning revealed that, a decline in sexual interest was significantly less common on CLOZ compared to RIS (0 vs. 64\%; chi(2)=6.1, df=1, p=0.01) or HAL/FLU (0 vs. 67\%; chi(2)=5.2, df=1, p=0.02), while a decline in the erectile frequency was significantly more common on RIS compared to CLOZ (40 vs. 93\%; chi(2)=6.2, df=1, p=0.01) or HAL/FLU (50 vs. 93\%; chi(2)=4.8, df=1, p=0.03) (0\%). For enjoyment of orgasm and ejaculatory volume, significantly fewer CLOZ compared to RIS subjects reported a decline (20 vs. 86\%; chi(2)=7.4, df=1, p=0.01). CONCLUSIONS: Sexual side effects are common clinically pertinent adverse effects associated with both novel and conventional antipsychotic medications. They deserve increased attention in clinical work and future research with emerging antipsychotic drugs.
