title: [Clinical efficacy of Viagra with behavior therapy against premature ejaculation].
abstract: 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.
  
  
  CONCLUSIONS
  During this clinical trial, Viagra combined with behavior therapy prolonged IELT, which suggests that Viagra may be helpful for the treatment of premature ejaculation.
