QEQ Treatment Responsiveness Evaluation Study

An Open-Label, Non-Comparative Study To Evaluate Treatment Responsiveness To The Quality Of Erection Questionnaire (QEQ) In Men With Erectile Dysfunction Treated With Viagra (Sildenafil Citrate)

The Quality of Erection Questionnaire (QEQ) is a new questionnaire that was developed to assess erectile attributes in men with erectile dysfunction. The study objective is to validate the Quality of Erection Questionnaire (QEQ) through the evaluation of subject responses to the QEQ regarding the quality and hardness of erections at baseline compared to subject responses post 6 and 10 weeks dosing with Viagra (sildenafil citrate).
