Background: With the advent of newer antipsychotic drugs, side effects such as sexual dysfunction have been a major contributor toward treatment compliance. There are only a few studies that have compared different atypical antipsychotic agents regarding sexual dysfunction. We have not come across any data in this area on Indian population. Aims: To determine and compare the frequency of sexual dysfunction associated with risperidone, olanzapine, and quetiapine, among patients with clinically stable schizophrenia. Settings and Design: It is a cross-sectional hospital-based study. The subjects were recruited for the study by the purposive sampling technique. Materials and Methods: The total sample size was 102, consisting of 25 each in the quetiapine and risperidone groups, 22 in the olanzapine group, and 30 healthy volunteers. A Brief Psychiatric Rating Scale and Sexual Functioning Questionnaire (SFQ) were administered. The Kruskal Wallis test was used to compare the variables in the demographic data and the mean chlorpromazine equivalent doses of the study groups. To analyze the sexual dysfunction, the mean scores on all the domains of sexual functioning in SFQ were compared across the study groups using the Chi square test, for proportions. Results and Conclusion: Twenty-three percent of the healthy volunteers had some impairment in one or more domains of sexual functioning. For the medication groups this was 96, 88, and 90%, respectively for risperidone, quetiapine, and olanzapine. However, there was statistically no significant difference across the study groups although it was relatively less with quetiapine.
