|Official Title:||Evaluate the Clinical Efficacy of Precious Metal Fiber Textile (Germanium Titanium π Element) for Erectile Dysfunction|
- The International Index of Erectile Function (IIEF-5) [ Time Frame: 3 months ]
The IIEF-5 score is the sum of the ordinal responses to the 5 items. 22-25: No erectile dysfunction 17-21: Mild erectile dysfunction 12-16: Mild to moderate erectile dysfunction 8-11: Moderate erectile dysfunction 5-7: Severe erectile dysfunction
- Quality of Erection Questionnaire (QEQ) [ Time Frame: 3 months ]
The QEQ is to be evaluated as a total score, which is the sum of responses to all items transformed onto a 5-30 scale.
The maximum score on the QEQ is 30, and a higher score indicates better function.
