Understanding the IIEF-5

The International Index of Erectile Function (IIEF-5) is a brief, validated screening questionnaire widely used in clinical and research settings. It helps quantify erectile function across five key domains.

It is not a diagnostic tool but a standardized way to track symptoms over time and communicate effectively with healthcare providers.

Common Pitfalls & Tips

Timeframe: The questions ask about the past 6 months, not just recent weeks.
Honesty: This is a self-assessment for your benefit. Choose the answer that best reflects your experience, not your ideal.
Context matters: The score is a snapshot. Stress, fatigue, relationship dynamics, and other factors can influence it.
Follow-up: A low score is a prompt for a conversation, not a final diagnosis. Many underlying causes are treatable.

Frequently Asked Questions

How accurate is the IIEF-5?

The IIEF-5 is a validated screening tool with good reliability in clinical studies. However, it is a self-reported measure and can be influenced by mood, recall, and interpretation. It's designed to indicate severity levels, not provide a precise medical diagnosis.

What if my score changes frequently?

Fluctuations are normal and can be due to stress, fatigue, or relationship dynamics. Tracking your scores over time (using the notes feature) can help identify patterns to discuss with a clinician.

I scored in the "No Dysfunction" range but still have concerns. What should I do?

The IIEF-5 focuses on specific erectile function domains. If you have other concerns (e.g., libido, ejaculation, relationship satisfaction), discuss them with a healthcare provider. This tool is not exhaustive.

When should I seek professional help?

Consider consulting a healthcare professional if: your score is consistently low (<=21), the issue causes you distress, it affects your relationship, or if you have sudden onset alongside other symptoms like chest pain or leg numbness (seek urgent care for the latter).

How should I measure/answer these questions properly?

Answer based on your actual experience over the past 6 months, not on isolated incidents or future hopes. Be honest with yourself. There are no right or wrong answers, only your personal experience.

Formulas & Assumptions

Scoring: Each of the 5 questions is scored from 1 (worst) to 5 (best). The total score is the sum of all answers (range: 5-25).

Categorization: Uses the standard IIEF-5 severity bands: Severe (5-7), Moderate (8-11), Mild-Moderate (12-16), Mild (17-21), None (22-25).

Rounding: Total score is presented as a whole integer (no decimals).

Validation: Based on the work by Rosen et al. (1999) and its abbreviated 5-item version.

Limitations: This tool does not account for age, comorbidities, or psychological factors. It is a screening aid only.
