Do You Have Erectile Dysfunction?


Erectile dysfunction is defined as the persistent inability to achieve or maintain an erection suitable for penetrative sex.

The Sexual Health Inventory for Men (SHIM) is a standard questionnaire used by doctors to categorize Erectile Dysfunction. This test is also called the International Index of Erectile Function (IIEF-5) Questionnaire.1

Note that the SHIM questionnaire will not diagnose the cause of your ED.  Diagnosis will require a medical examination by your doctor.

Patient Instructions

Sexual health is an important part of an individual's overall physical and emotional well-being. Erectile dysfunction, also known as impotence, is one type of very common medical condition affecting sexual health. Fortunately, there are many different treatment options for erectile dysfunction. This questionnaire is designed to help you and your doctor identify if you may be experiencing erectile dysfunction. If you are, you may choose to discuss treatment options with your doctor.

Each question has several possible responses. Select the response that best describes your own situation. Please be sure that you select one and only one response for each question.

Over the Past 6 Months:

How do you rate your confidence that you could get and keep an erection?

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

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

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

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



If you find that you have Erectile Dysfunction, you should see your doctor.  There are many different causes for ED, and it may be a symptom of a serious medical condition.  Your doctor can determine the cause, and recommend appropriate treatments.
