About the 5-Question International Index of Erectile Function (IIEF-5 Test)
As a diagnostic tool, the simplified IIEF-5 has been shown to be a simple method that can be used to evaluate this condition in studies with a large number of men.
It is not a substitute for personalized medical attention for men in need of ED treatment, but it can be a useful data collection tool for initial screening, particularly for the expeditious processing of larger numbers of men being tested for erectile dysfunction.
