The International Index of Erectile Function (IIEF) score does not differentiate between specific causes of erectile dysfunction (ED) when compared to penile blood flow studies (PBFS). Even patients with normal vascular function reported low erectile performance scores.

Area of Science:

  • Urology
  • Andrology
  • Sexual Medicine

Background:

  • The International Index of Erectile Function (IIEF) is widely used for assessing erectile dysfunction (ED) severity and drug efficacy.
  • Objective assessment of ED etiology is crucial for effective treatment.

Purpose of the Study:

  • To compare subjective IIEF scores with objective ED severity and etiology determined by pharmacologic testing (prostaglandin E1) and penile blood flow studies (PBFS).

Main Methods:

  • Five IIEF questions quantifying erectile performance were compared with PBFS data in 89 patients.
  • PBFS diagnoses included arterial insufficiency (AI), cavernous venous occlusive disease (CVOD), and mixed vascular ED.
  • Visual erection ratings were also compared with IIEF and Viagra Study Group criteria.

Main Results:

  • IIEF scores differed significantly between normal and abnormal vascular groups but not among subgroups of ED etiologies.
  • Patients with normal vascular function after testing reported surprisingly low IIEF scores.
  • No statistically significant differences in IIEF scores were found among AI, mixed vascular ED, and CVOD subgroups.

Conclusions:

  • IIEF scores do not statistically differentiate among specific vascular etiologies of ED as determined by PBFS.
  • IIEF scores may aid in sexual history taking but do not predict pharmacologic testing outcomes for specialists.
  • The study highlights a discrepancy between subjective self-ratings and objective vascular assessments in ED.
