A new test combining low-dose intracavernous injection (ICI) and visual erotic stimulation (VES) effectively assesses erectile dysfunction. This powerful and safe method, along with a post-investigation questionnaire (PIQ), achieved adequate erections in 75% of patients without prolonged side effects.

Area of Science:

  • Urology
  • Andrology
  • Sexual Medicine

Background:

  • Erectile dysfunction (ED) diagnosis requires effective assessment tools.
  • Current methods may have limitations in accurately predicting erectile response.

Purpose of the Study:

  • To evaluate the efficacy and safety of combining low-dose intracavernous injection (ICI) with visual erotic stimulation (VES) for ED assessment.
  • To assess the utility of a post-investigation questionnaire (PIQ) in capturing patient-reported erectile function.
  • To compare the combined ICIVES test with ICI or VES alone.

Main Methods:

  • A study involving 90 patients with erectile dysfunction.
  • Administration of visual erotic stimulation (VES) alone.
  • Administration of low-dose intracavernous injection (ICI) alone.

  • Combined intracavernous injection and visual erotic stimulation test (ICIVES).
  • Use of a post-investigation questionnaire (PIQ) to assess erections after patient departure.

    • Main Results:

    • The combined ICIVES test achieved adequate erections in 67% of patients, significantly higher than VES (19%) or ICI (11%) alone.
    • Overall, 75% of patients achieved adequate erections when considering both in-office and PIQ responses.
    • No instances of prolonged erections were observed, indicating a safe testing profile.

    Conclusions:

    • The combination of low-dose ICI and VES, supplemented by a PIQ, is a highly effective and safe diagnostic tool for erectile dysfunction.
    • This integrated approach significantly improves the rate of achieving adequate erectile response compared to individual methods.
    • The ICIVES test with PIQ is recommended for patient selection for autoinjection therapy.
