About this test
What is a Testicle Blood Flow Doppler?
A Doppler ultrasound of the testis uses sound waves to create a moving image of the testicular tissue and the blood vessels that supply it. It measures how well blood is flowing through the testis and can show if there is any blockage or abnormality.
Key Parameters
| Parameter | What it shows |
|---|---|
| Peak Systolic Velocity (PSV) | Speed of blood during heart contraction |
| End Diastolic Velocity (EDV) | Speed of blood during heart relaxation |
| Resistive Index (RI) | Ratio of PSV to EDV, indicates resistance to flow |
| Color Doppler map | Visual representation of flow direction and velocity |
Why is it done?
- Evaluate pain or swelling in the testis
- Investigate infertility or low sperm count
- Monitor testicular torsion or trauma
- Screen for testicular cancer when combined with other imaging
- Follow up on known vascular or inflammatory conditions
Early Detection
This test can help identify signs of testicular torsion, varicocele, or early testicular cancer, but it does not diagnose on its own. A doctor interprets the result together with symptoms, history, and other tests.
What an abnormal result may mean
- High velocity or low resistance can suggest a varicocele or increased blood flow due to inflammation.
- Low velocity or high resistance may indicate a blockage, ischemia, or testicular torsion.
- Results can be influenced by hydration, recent exercise, medications, or body position.
Who might be advised to get this test?
- Men with acute or chronic testicular pain
- Men with infertility concerns
- Men with a history of testicular trauma or surgery
- Men with a family history of testicular cancer
Quick Takeaway
A testicle Doppler ultrasound is a safe, non‑invasive way to assess blood flow to the testis and can flag potential problems early, but it is part of a broader diagnostic picture.
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 scrotum, and a handheld transducer is moved over the area. The scan takes about 10–15 minutes.
- Discomfort: None; the probe is non‑invasive.
- Precautions: Avoid heavy exercise 24 hours before; stay well‑hydrated.
- Note: Confirm specific preparation with your doctor or the lab. This information is for educational purposes only and not a substitute for professional medical advice.
Sample type: Imaging
Report parameter guide
Peak Systolic Velocity
Maximum speed of blood flow during heart contraction
Low: may indicate reduced blood supply or blockage
High: may indicate increased blood flow due to inflammation or high cardiac output
End Diastolic Velocity
Speed of blood flow at the end of heart relaxation
Low: may indicate high resistance or blockage
High: may indicate low resistance or hyperemia
Resistive Index (RI)
Ratio showing resistance to blood flow in the testicle
Low: may indicate low resistance or hyperemia
High: may indicate high resistance or obstruction
Pulsatility Index (PI)
Measure of blood flow variation during cardiac cycle
Low: may indicate low resistance or hyperemia
High: may indicate high resistance or obstruction
Color Doppler Flow Pattern
Visual representation of blood flow direction and velocity
Low: may show absent or reduced flow
High: may show increased or turbulent flow
