To evaluate the efficacy and safety of sildenafil citrate in the treatment of premature ejaculation (PE) complicated by erectile dysfunction (ED).


Forty-five patients of PE complicated by ED received flexible doses of sildenafil from 50 to 100 mg for 1 to 3 months. Intravaginal ejaculatory latency time (IELT) and sexual satisfaction ratio (SSR) of partner were recorded to evaluate the effect of PE treatment, as well as the general efficacy and satisfaction of ED treatment. And the difference of IIEF-5 before and after the treatment were compared.


Twenty-seven patients had their PE improved and the effective rate was 60%. Forty patients reported the improvement in erection and the percentage of erectile improvement was 88.88%. All the 27 patients with improvement of PE achieved effective erection through the administration of 50 mg sildenafil and the satisfaction rate reached 81.48%. On the other hand, only 1 case (5.56%) reported satisfaction over the treatment in the 18 patients who did not obtain improvement of PE. Between the PE improvement group and non-improvement group, there were significant differences (P < 0.001) shown in IIEF-5 scores before and after the treatment. Mild or moderate side effects were reported in 9 patients(20%), who recovered without any treatment.


To premature ejaculation patients with ED, sildenafil can safely and effectively improve their erectile function, the satisfaction over the ED treatment outcome means that their PE symptoms could be alleviated.
