    Abstract:
    OBJECTIVE: To evaluate the efficacy of sildenafil on nocturnal penile tumescence (NPT). METHODS: Thirty-five patients with erectile dysfunction (ED), 28 cases of organic ED and 7 cases of psychogenic ED, were treated with sildenafil 100 mg before bedtime. The NPT of the patients was observed by using NEVA. RESULTS: Erectile function significantly improved in the 28 cases of organic ED (P < 0.05), but not in the 7 cases of psychogenic ED (P > 0.05). CONCLUSION: Sildenafil can improve NPT of organic ED patients without sexual stimulation.
