Abstract

Erectile dysfunction is a man's persistent or recurrent inability to achieve and maintain erection for a satisfactory sexual relationship. As diabetes is a major risk factor for erectile dysfunction, the prevalence of erectile dysfunction among diabetic men has been reported as 35% to 90%. This randomized, parallel-group, double-blind, placebo-controlled trial investigated the effects of a topical saffron (Crocus sativus L) gel on erectile dysfunction in diabetic men. Patients were randomly allocated to 2 equal groups (with 25 patients each). The intervention group was treated with topical saffron, and the control received a similar treatment with placebo. The 2 groups were assessed using the International Index of Erectile Function Questionnaire before the intervention and 1 month after the intervention. Compared to placebo, the prepared saffron gel could significantly improve erectile dysfunction in diabetic patients (P < .001). This preliminary evidence suggests that saffron can be considered as a treatment option for diabetic men with erectile dysfunction.
