Abstract:
Sildenafil (Viagra) citrate has been well accepted by physicians and patients for its reliable efficacy and safety in the treatment of erectile dysfunction (ED) ever since its introduction into clinical andrology in China 10 years ago. It has been proved effective for various ED subgroups, regardless of causes, severity and age. Recent studies show that sildenafil also benefits patients with premature ejaculation, either used alone or in combination with other therapies.
