Erectile Dysfunction Score Calculator

This calculator scores the standard 5-question IIEF-5 (SHIM) questionnaire into a 1-25 total, then classifies severity into five clinical bands from 22-25 (no ED) down to 1-7 (severe). Rosen and colleagues published the IIEF-5 in 1999 as an abridged, 5-item version of the longer 15-item International Index of Erectile Function, validating it as a diagnostic screening tool for erectile dysfunction — it's also known as SHIM, the Sexual Health Inventory for Men, the name it's given on many clinic intake forms. IIEF-5 total score, Severity, and Quality of life impact respond only to the five questionnaire answers -- your age, BMI, and comorbidity flags never enter that calculation at all, even though they clearly matter for erectile function in reality. Age and the comorbidity flags (diabetes, hypertension, smoking) instead drive a separate Vascular risk score, reflecting the clinical reality that ED is often an early marker of cardiovascular disease rather than a symptom of it.

That vascular risk score then feeds Psychological component (%) in the opposite direction -- a higher vascular risk score, or an older age, lowers the estimated likelihood that psychological factors explain the ED, since more physical risk factors present makes a vascular cause more probable. Predicted PDE5i response (%) starts at 80% and is reduced by diabetes, older age, smoking, and more severe IIEF-5 scores, reflecting published lower medication response rates in those groups. This tool approximates a validated screening questionnaire and risk framework; it does not diagnose ED or its cause, and a low score should prompt a medical evaluation rather than self-treatment.
