【Abstract】 s: Objectives: To assess the clinical efficacy of oral sildenafil on the patients with ED of various etiologies and ages. Methods: 88 cases treated with oral sildenafil within the first 4～22 weeks were evaluated with a self administered questionnaire (IIEF 5) before and just after therapy. A contrast group included 50 patients with ED. Results: Overall satisfaction with sildenafil was 80.7% and a significantly positive correlation existed between baseline IIEF 5 and that after oral sildenafil. No significant differences were observed on the patients with various ages, but a significant difference on the curative rates and IIEF 5 values were found between the patients with neurological ED and those with psychogenic ED. Conclusions: Oral sildenafil is effective for various ED and IIEF 5 value is a reliable reference.更多还原
