What is the IIEF-EF questionnaire for erectile dysfunction?

The IIEF-EF (International Index of Erectile Function – Erection Function) is a validated medical questionnaire used by urologists to assess the severity of erectile dysfunction. It consists of 6 questions about a man's sexual function over the past four weeks, covering erection frequency, hardness, ability to penetrate, ability to maintain erection, difficulty maintaining erection, and confidence in erections.

How many questions are in the IIEF-EF questionnaire?

The IIEF-EF questionnaire contains 6 questions. They assess: how often erections occur during sexual activity, how often erections are hard enough for penetration, how often penetration is achieved, how often erection is maintained after penetration, how difficult it is to maintain erection to completion, and confidence in getting and keeping an erection.

Why do urologists use the IIEF-EF questionnaire?

The IIEF-EF is used because erectile dysfunction affects not only the patient but also their partner significantly. It provides urologists with a standardized, objective measurement of erectile function severity, which is essential alongside medical history, physical examination, and laboratory investigations when evaluating a patient.

What time period does the IIEF-EF questionnaire cover?

The IIEF-EF questionnaire asks patients to reflect on their sexual function over the past four weeks. Patients are encouraged to answer as honestly and clearly as possible to ensure accurate assessment.

Is erectile dysfunction a common problem?

Yes. Erectile dysfunction is one of the most common men's health issues seen in urology clinics. It can affect men of various ages and has a significant negative impact on quality of life and relationships. It is a natural medical condition that deserves open discussion and proper evaluation by a urologist or andrologist.

How to Interpret Your IIEF-5 Score

Add up the scores from all 5 questions. The total IIEF-5 score ranges from 5 to 25. The severity of erectile dysfunction is classified as follows:

Total Score	Severity of ED
22 – 25	No erectile dysfunction
17 – 21	Mild ED
12 – 16	Mild to moderate ED
8 – 11	Moderate ED
5 – 7	Severe ED

A cutoff score of 21 has been shown to discriminate best between men with and without ED, with a sensitivity of 0.98 and specificity of 0.88. A score of 21 or below suggests the presence of erectile dysfunction and is worth discussing with a urologist.

Q1: What is the IIEF-5 questionnaire and why is it used?

The IIEF-5 (the abridged 5-item version of the International Index of Erectile Function), also known as the Sexual Health Inventory for Men (SHIM), is a validated clinical questionnaire used by urologists worldwide to screen for and assess the severity of erectile dysfunction. It consists of 5 questions covering erection confidence, firmness, the ability to maintain an erection, difficulty maintaining it, and intercourse satisfaction over the past 6 months. The total score helps classify ED from mild to severe, guiding appropriate treatment decisions.

Q2: How is the IIEF-5 score interpreted?

The IIEF-5 score ranges from 5 to 25. A score of 22-25 indicates no erectile dysfunction, 17-21 indicates mild ED, 12-16 indicates mild-to-moderate ED, 8-11 indicates moderate ED, and 5-7 indicates severe ED. A cutoff score of 21 best distinguishes men with ED from those without. Your urologist will use this score alongside your medical history and physical examination to recommend the most appropriate treatment.

Q3: Is erectile dysfunction a sign of a serious underlying condition?

Erectile dysfunction can sometimes be an early warning sign of underlying cardiovascular disease, diabetes, hormonal imbalance, or psychological conditions. This is why a thorough medical evaluation by a urologist or andrologist is important before starting any treatment. In many cases, treating the underlying cause can significantly improve or resolve ED.

Q4: What are the treatment options for erectile dysfunction?

Treatment options for erectile dysfunction range from lifestyle modifications and oral medications such as PDE5 inhibitors (e.g., Tadalafil, Sildenafil) to low-intensity extracorporeal shockwave therapy, platelet-rich plasma injection, and surgical implants for severe cases. The appropriate treatment depends on the severity of ED, underlying causes, and individual patient preference as assessed by your urologist.

Q5: When should I see a urologist for erectile dysfunction?

You should consult a urologist if you experience persistent difficulty achieving or maintaining an erection sufficient for satisfactory sexual intercourse, especially if the problem occurs in more than half of your sexual attempts. Early evaluation is important as ED can significantly impact quality of life and may indicate treatable underlying medical conditions.
