This study assessed the effect of obsessive compulsive disorder (OCD) on sexual function. Twenty-three outpatients who met Diagnostic and Statistical Manual of Mental Disorders (DSM-IV: American Psychiatric Association, 1994) diagnostic criteria for OCD were obtained from consecutive cases recruited to Osmangazi University Department of Psychiatry and were compared to a group of 26 generalized anxiety disorder (GAD) female outpatients. Psychiatric, psychological, and sexual information was obtained with the Maudlsey Obsessional-Compulsive Inventory (Hodgson & Rachman, 1977), the Sate-Trait Anxiety Inventory (Spielberger, Gorsuch, & Lushere, 1970), and the Golombok Rust Inventory of Sexual Satisfaction (Rust & Golombok, 1986). We found that the women with OCD were more sexually nonsensual, avoidant, and anorgasmic than the women with GAD. These data suggest that OCD may be a risk factor for sexual problems in women.
