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.
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.
