Diagnostic test
Evidence status: EstablishedPenile Doppler Ultrasound for Erectile Dysfunction
What is a penile Doppler ultrasound?
A penile Doppler (duplex) ultrasound is a scan that measures blood flow into and out of the penis. It helps a urologist tell whether ED is related to arterial inflow or to a venous leak, which can influence which treatments are worth discussing. It is used in selected men, not everyone.
Key fact: Penile Doppler ultrasound can assess blood flow into and out of the penis in selected men with erectile dysfunction. (European Association of Urology, 2026; page updated )

Key takeaways
- It shows how well blood enters and stays in the penis.
- It can help distinguish arterial insufficiency from venous leak.
- The doctor decides whether you need it.
What the test involves
Preparation
The doctor reviews your history and explains the test. You are told whether to adjust any medicines.
Inducing an erection
A small dose of a medicine that widens blood vessels is usually injected into the penis to produce an erection. Visual or manual stimulation may be used too.
Scanning
An ultrasound probe measures blood velocity in the penile arteries and assesses whether blood is retained.
Interpretation
The urologist interprets the results alongside your history and examination.
What the results can show
Doctors commonly look at the speed of blood entering the arteries (peak systolic velocity) and the residual flow in the diastolic phase. Reference values, such as a peak systolic velocity below about 25 cm/s suggesting arterial insufficiency, or a high end-diastolic velocity suggesting venous leakage, are interpreted by the clinician with the full picture, not in isolation.
Risks and limits
Prolonged erection
The injected medicine can rarely cause an erection lasting too long. Seek urgent help if an erection lasts more than four hours.
Not always needed
Many men are treated without a Doppler scan. It is most useful when blood-flow problems are suspected or before certain procedures.
Anxiety can affect results
Anxiety in the examination room can limit the erection and the readings, which the clinician takes into account.
Not a treatment
It is a diagnostic test. It does not treat ED.
How it relates to treatment choice
Blood-flow findings can help the doctor decide whether options such as shockwave therapy may be relevant, and what is realistic in a venous leak. The 2026 European Association of Urology (EAU) guideline says intracavernosal PRP for erectile dysfunction should be used only in a clinical-trial setting.
Treatments the results may inform
P-Shot / PRP
ExperimentalPlatelet-rich plasma is prepared from your own blood and injected into penile tissue after numbing.

EmergingLow-intensity shockwaves are applied to the penis. The proposed aim is to support blood-flow related pathways.
Read the guide →Stem Cell Therapy
ExperimentalA cell-based preparation is injected into penile tissue with the aim of supporting tissue repair.
Read the guide →Exosome Therapy
ExperimentalExosomes are tiny cell-released vesicles being studied for signalling that may support tissue repair.

Frequently asked questions
Does a Doppler scan hurt?
The injection can cause brief discomfort. The scan itself is painless. Experiences differ.
