title: [Benefits of tadalafil to ED patients].
abstract: OBJECTIVE
  To gain a deeper insight into the benefits of oral tadalafil for patients with erectile dysfunction (ED).
  
  
  METHODS
  From January 2008 to June 2009, we conducted a nationwide survey on the quality of male erectile function among the outpatients under the direction of the Chinese Association of Andrology. A total of 205 ED patients were prescribed oral tadalafil and accomplished a questionnaire investigation after 4 weeks of medication. We compared various parameters of the patients before and after the treatment.
  
  
  RESULTS
  Four weeks of oral tadalafil medication achieved a total rate of effectiveness of 85.9% (176/205). The proportion of those with moderate to severe ED was decreased from 67.8% (139/205) before medication to 16.6% (34/205) after it. Those who enjoyed sexual life were increased from 21.5% (44/205) before medication to 84.9% (174/205) after it. Only 1.0% (2/205) of the patients could achieve grade 4 penile hardness before the treatment, as compared with 60.5% (124/205) after it. And the frequency of sexual intercourse was significantly increased, over 4 times in 90.2% (159/205) of the patients.
  
  
  CONCLUSIONS
  Oral tadalafil, with its sure effectiveness on ED, can bring great benefits to the sexual life of ED patients.
