Sexual Health Inventory for Men (SHIM)

INSTRUCTIONS: Each question has five possible responses. Circle the number that best describes your own situation. Select only one answer for each question.

Over the last six months:

1. How do you rate your confidence that you could keep an erection?

2. When you had erections with sexual stimulation, how often were your erections hard enough for penetration (entering your partner)?

3. During sexual intercourse, how often were you able to maintain your erection after you had penetrated (entered) your partner?

4.During sexual intercourse, how difficult was it to maintain your erection to completion of intercourse?

5. When you attempted sexual intercourse, how often was it satisfactory for you?

Total SHIM score

Higher score = better sexual function


Information for clinicians:

  • Add together the numbers corresponding to the answers for all the questions.
  • If the patient’s score is 21 or less, erectile dysfunction (ED) should be addressed.
  • The SHIM score measures the severity of the patient’s ED in the following manner: 
    • 22 – 25: No significant erectile dysfunction
    • 17 – 21: Mild erectile dysfunction
    • 12 – 16: Mild-to-moderate erectile dysfunction
    • 8 – 11:  Moderate erectile dysfunction
    • 5 – 7:  Severe erectile dysfunction 


The purpose of SHIM

  • With the advent of oral therapy for ED, the need for accurate diagnosis is greater than ever
  • The SHIM questionnaire (also known as IIEF-5) is an abridged and slightly modified five-item version of the 15-item International Index of Erectile Function (IIEF), designed for easy use by clinicians to diagnose the presence & severity of ED in clinical settings
  • This diagnostic tool may reduce the number of incorrectly diagnosed or underdiagnosed cases
  • It is intended to complement the physical examination and patient history as a means of detecting ED
