A comparison of the International Index of Erectile Function and XXXX studies.

@entity1 @entity323 @entity9085 @entity5015 @entity4096 @entity1211
OBJECTIVE: To evaluate the ability of the five-item version of the International Index of Erectile Function (IIEF-5) to diagnose the vascular aetiology and severity of @entity323 ( @entity323 ), and to compare it with pharmacological testing and duplex Doppler ultrasonography, as such questionnaires are widely used by the pharmaceutical industry to categorize the severity of @entity323 and to assess the efficacy of drug therapy. @entity1 AND METHODS: In all, 80 @entity1 (mean age 45.2 years, sd 14.0; mean duration of @entity323 3.5 years) were reviewed by an examiner unaware of their IIEF scores during testing. Penile blood flow was assessed in each @entity1 after an intracavernosal injection with @entity5015 (10 micro g), with self-stimulation in privacy. The peak systolic velocity, end diastolic velocity and resistive index were measured for the vascular diagnosis. Visual ratings of erectile responses were also used for analysis. RESULTS: Of the 80 @entity1 , 30 had a normal vascular response, 38 @entity9085 and 12 were diagnosed with @entity1211 . There was no significant difference in the IIEF scores among @entity1 with a normal vascular response, @entity4096 . Analysis of visual ratings of erections showed no difference in IIEF scores among the different groups of @entity1 . CONCLUSION: The IIEF was designed and developed specifically for assessing and evaluating sexual function in clinical trials. However, as shown here, the IIEF cannot and should not be used as a tool to diagnose or compare specific vascular causes of @entity323 .
