Know Your Severity
Get an instant 5–25 score that tells you whether your symptoms are mild, moderate, or severe — the same metric doctors use.
Pick the Right Treatment
Mild ED may respond to lifestyle changes, while moderate-to-severe ED points toward medication or devices — your score narrows the options.
Plan Your Budget
Knowing your severity helps you avoid overpaying for treatments you don't need — or under-treating a problem that warrants more support.
Talk to Your Doctor
Bring your score to your next appointment. It gives your physician a starting point and speeds up the conversation.
It takes about 60 seconds. Your answers are confidential and never stored — results appear only on your screen.

About the IIEF-5 Questionnaire
The IIEF-5 is an abridged, 5-item version of the 15-item International Index of Erectile Function, developed and validated by urology researchers. It is the most widely used self-report tool for screening ED severity in clinical and research settings.
Each question is scored from 0–5. The total ranges from 5 to 25 (lower scores indicate greater dysfunction). The tool helps identify severity but is not a diagnosis — only a physician can diagnose ED and its underlying causes.
This tool is for educational and screening purposes only and is not a substitute for professional medical advice, diagnosis, or treatment. Always consult a licensed physician about your specific symptoms and health conditions.
