About this test
What is Penile Blood Flow Doppler?
Penile Blood Flow Doppler is a non‑invasive imaging test that uses ultrasound waves to evaluate the blood flow to the penis. It helps doctors understand how well the penis receives and retains blood, which is essential for normal erectile function.
Key Parameters Measured
| Parameter | What it shows |
|---|---|
| Peak Systolic Velocity (PSV) | Speed of blood flow during heartbeats |
| End‑Diastolic Velocity (EDV) | Blood flow when the heart is relaxed |
| Resistive Index (RI) | Resistance to blood flow in penile arteries |
| Penile Artery Diameter | Size of the artery supplying the penis |
Why is this test done?
- To investigate erectile dysfunction (ED) when other causes have been ruled out.
- To assess vascular health of the penis before procedures like penile implants.
- To monitor the effectiveness of treatments aimed at improving blood flow.
- As part of a routine check‑up for men with risk factors such as diabetes or hypertension.
Early Detection
This test can help identify signs of arterial insufficiency or venous leakage, but it does not diagnose a disease on its own. A doctor interprets the results together with symptoms, history, and other investigations.
What do abnormal results mean?
- Low PSV may indicate reduced arterial inflow.
- High EDV or low RI can suggest venous leakage.
- Results can be influenced by hydration, medications (e.g., PDE5 inhibitors), and recent sexual activity.
Who might be advised to get this test?
- Men experiencing erectile dysfunction.
- Men with cardiovascular risk factors (diabetes, high blood pressure, smoking).
- Patients scheduled for penile prosthesis surgery.
- Men undergoing evaluation for sexual health concerns.
Quick Takeaway
Penile Blood Flow Doppler is a safe, ultrasound‑based test that measures blood flow parameters to help diagnose vascular causes of erectile dysfunction and guide treatment decisions.
Used for detecting / monitoring
Before your test
Preparation
- Fasting: No fasting required.
- If combined with fasting tests: Follow the strictest fasting instruction (usually 8–12 hours).
- Procedure: A gel is applied to the penis and a handheld ultrasound probe is moved over the area. The test takes about 15–20 minutes.
- Discomfort: None; the probe is non‑invasive and does not penetrate the skin.
- Precautions: Avoid alcohol and strenuous exercise 24 hours before the test; inform the technician if you are taking medications that affect blood flow (e.g., PDE5 inhibitors).
- Aftercare: You can resume normal activities immediately.
Please confirm specific preparation instructions with your doctor or the lab. This information is for educational purposes only and not a substitute for professional medical advice.

Report parameter guide
Peak Systolic Velocity
Maximum speed of blood flow during the heart's contraction phase
Low: may indicate reduced arterial inflow or arterial blockage
High: may suggest increased arterial flow or hyperdynamic circulation
End Diastolic Velocity
Speed of blood flow at the end of the heart's relaxation phase
Low: may indicate increased resistance in the penile arteries or venous leakage
High: may suggest low resistance or abnormal arterial flow
