Objective:
To study the efficacy of Viagra combined with behavior therapy against premature ejaculation (PE).
Methods:
Sixty PE patients were divided into two groups randomly: control group (behavior therapy alone) and the group of Viagra combined with behavior therapy. Intra-vaginal ejaculation latency time (IELT) and the coitus satisfaction of the patient and the partner were recorded before and after treatment.
Results:
The IELTs of the two groups were 0.80 +/- 0.20 and 0.73 +/- 0.24 minutes respectively before treatment, and 1.82 +/- 0.54 and 3.63 +/- 0.55 minutes respectively after treatment. As for IELT and satisfaction degree, Viagra produced better result than behavior therapy.
Conclusion:
During this clinical trial, Viagra combined with behavior therapy prolonged IELT, which suggests that Viagra may be helpful for the treatment of premature ejaculation.
