While life-sustaining, chronic dialysis is associated with substantial impairments in health-related quality of life (HRQoL) (1,2). The well-recognized decrements in HRQoL in patients with ESRD are likely related to multiple factors, including functional limitations, impaired social well being, vocational disruptions associated with a thrice-weekly or quotidian treatment, and a large burden of physical and emotional symptoms. Specific symptoms that occur with regularity in patients on chronic dialysis are fatigue, cramping, pain, and dyspnea (3,4). Another symptom that appears to occur frequently in patients with ESRD is sexual dysfunction, etiologies for which include hormonal dysregulation, vascular disease, autonomic dysfunction, medication side effects, and psychologic illness such as depression (5,6).To date, the preponderance of research on sexual dysfunction in patients with ESRD has focused on men. Although there are several domains of male sexual function that may be impaired, the most frequently studied has been erectile dysfunction (ED), in part because of the availability of efficacious pharmacological therapy (7,8). Multiple studies have documented ED to be highly prevalent and strongly correlated with HRQoL in men on chronic dialysis and have identified the clinical predictors of this symptom (9,10). In a comprehensive cross-sectional study of 302 communitybased male hemodialysis patients, Rosas et al. (9,11) found that ED was present in 82%, was severe in 45%, and was associated with impairments in multiple domains of HRQoL. A subsequent study by Türk et al. (10) demonstrated that ED was present in 104 (70%) of 148 patients on chronic hemodialysis and was closely correlated with decrements in physical and mental well being. Older age and diabetes were associated with ED in both of these studies. Data from these and other studies, which collectively enrolled thousands of patients, confirm the high prevalence and clinical importance of ED in men on dialysis and inform our understanding of factors that help predict the presence of this symptom.Although women comprise approximately one-half of all patients with ESRD, considerably less attention has been paid to female sexual dysfunction in this population. A series of small past studies suggest that sexual dysfunction is common among women receiving chronic dialysis. Yazici et al. (12) studied 117 women with ESRD and found that sexual dysfunction was present in 94% of patients on peritoneal dialysis and 100% of those on hemodialysis. More recently, Seethala et al. (13) found impairments in multiple domains of sexual function in 66 female patients on chronic dialysis and high rates of sexual dysfunction among women with partners and those who reported to be sexually active. Notwithstanding these findings, studies investigating this issue were limited by the enrollment of small numbers of patients and the lack of statistical power to elucidate which clinical factors are associated with and predict the presence of sexual dysfunction.In an effort to br...
