Prevalence of priapism in individuals with sickle cell disease and implications on male sexual function

ABSTRACT Objective To evaluate epidemiological aspects of priapism in patients with sickle cell disease, and these aspects impact on adult sexual function. Methods This was a cross-sectional study including individuals with sickle cell disease who were evaluated at a reference center for sickle cell. Participants completed a structured questionnaire about their sociodemographic characteristics and priapism events. Sexual function was assessed using validated two instruments, the Erection Hardness Score and one about the sex life satisfaction. Results Sixty-four individuals with median aged of 12 (7 to 28) years were interviewed. The prevalence of priapism was 35.9% (23/64). The earliest priapism episode occurred at 2 years of age and the latest at 42 years. The statistical projection was that 71.1% of individuals of the study would have at least one episode of priapism throughout life. Patients with episodes of priapism (10/23) had significantly worse erectile function Erection Hardness Score of 2 [1-3]; p=0.01 and were less satisfied with sexual life 3 [3-5]; p=0.02. Conclusion Priapism is usually present in childhood, and severe episodes are associated with cavernous damage, impairment in the quality of the erection, and lower sexual satisfaction.
