Abstract：Objective:To evaluate the effect of low-dose phosphodiesterase type 5 inhibitor tadalafil on aaefial erectile dysfunction.Methods:Fony-three patients with arterial erectile dysfunction were requested to take 5 mg tadalafil after supper on alternate days for 4 weeks.All the patients were scored on IIEF-5 and received intracavernous injection of 10 μg prostaglandin E1,followed by measurement of the peak systolic velocity(PSV)of the cavernosal artery by color Doppler ultrasonography. Results:Statistic analyses showed an obvious increase in the IIEF-5 score and PSV after the treatment,with significant differences from the baseline(P <0.01). Conclusion:Low-dose tadalafil can significantly improve the PSV of the cavernosal artery and hence the erectile function of arterial ED patients.
