Abstract:Objective: The pathogenesis of recurrent priapism is currently being investigated based on the regulation of the phosphodiesterase 5 (PDE5) enzyme. We explored the daily use of PDE5 inhibitors to treat and prevent priapism recurrences.

Six men (85.7%) had idiopathic priapism recurrences and one man (24.3%) had sickle cell disease-associated pr… Show more
