How to Use This Calculator

Answer all five IIEF-5 questions (Q1–Q5) on a scale of 1–5 based on your experiences over the past 4 weeks.
Enter your age and indicate yes/no for diabetes, hypertension, and smoking status.
Enter your BMI to factor vascular risk from body composition.
Review the IIEF-5 total score (1–25): 22–25 = no ED, 17–21 = mild, 12–16 = mild-moderate, 8–11 = moderate, 1–7 = severe.
Check Predicted PDE5i response (%) for medication likelihood and Vascular risk score to guide discussion with your doctor.

What each input means

Q1: Confidence in erection (1-5): How confident are you that you could get and keep an erection? 1=very low, 5=very high.
Q2: Erections for penetration (0-5): Erections hard enough for penetration? 0=no activity, 1=almost never, 5=almost always.
Q3: Maintaining after penetration (1-5): Ability to maintain erection after penetration? 1=almost never, 5=almost always.
Q4: Difficulty maintaining (1-5): How difficult to maintain erection to completion? 1=extremely difficult, 5=not difficult.
Q5: Satisfaction (1-5): Satisfaction with intercourse? 1=almost never, 5=almost always.
Age: Your age in years.
Diabetic (0=No, 1=Yes): 1 if you have diabetes.
Hypertensive (0=No, 1=Yes): 1 if you have high blood pressure.
Smoker (0=No, 1=Yes): 1 if you currently smoke.
BMI: Body mass index (weight kg / height m squared).

What each result means

IIEF-5 total score (1-25): Total IIEF-5 / SHIM score. 22-25=no ED, 17-21=mild, 12-16=mild-moderate, 8-11=moderate, 1-7=severe.
Severity (0-4): 0=no ED, 1=mild, 2=mild-moderate, 3=moderate, 4=severe.
Vascular risk score (0-100): Estimated contribution of vascular risk factors to ED.
Psychological component (%): Estimated likelihood that psychological factors contribute to ED.
Predicted PDE5i response (%): Estimated likelihood of responding to PDE5 inhibitor medication.
Quality of life impact (0-100): Estimated quality-of-life impact. Higher = greater impact.
