Advanced Diagnostic Testing for Erectile Dysfunction at Trusted Urology Clinics

If you’re struggling with erectile dysfunction (ED) or suspect your symptoms may be linked to blood flow issues, a Penile Doppler Ultrasound (음경 도플러 초음파 – eumgyeong dopulleo choumpa) offers precise insight into your vascular health. This non-invasive test is a cornerstone of modern sexual medicine and is widely available in Korea—particularly at expert-led clinics like Gangnam J Urology Clinic, where confidentiality and comfort are prioritized for both locals and international patients.

What Is a Penile Doppler Ultrasound?

A Penile Doppler Ultrasound is an imaging test that uses high-frequency sound waves to evaluate blood flow into and out of the penis. It helps determine whether vascular issues—like poor arterial inflow or venous leakage—are contributing to erectile dysfunction.

This test is especially useful for:

• Men not responding to oral ED medications
• Younger men with unexplained or sudden-onset ED
• Men considering invasive treatments like injections or implants
• Legal documentation of ED for insurance or surgical candidacy

Who Should Consider Penile Doppler Testing?

You may benefit from this test if:

• You have persistent difficulty achieving or maintaining erections
• ED has developed suddenly or progressively worsened
• Oral medications (like Viagra or Cialis) are ineffective
• You want to explore surgical or non-pill-based ED treatments
• There’s a concern about venous leakage (erections that are lost quickly)
• You’ve had pelvic trauma or prior prostate surgery

What Happens During a Penile Doppler Ultrasound in Korea?

At Gangnam J Urology Clinic, the procedure is conducted in a private exam room by a urologist or trained technician, and typically lasts 20–30 minutes.

Step-by-Step Process:

 1. Baseline Scan (Flaccid State):
The doctor begins by scanning the penis in a relaxed state to assess structural anatomy and baseline blood vessels.

 2. Medication Injection (Vasoactive Agent):
A small dose of a medication (usually prostaglandin E1) is injected into the base of the penis to induce an erection. This mimics natural arousal and enables measurement of blood flow under arousal conditions.

 3. Doppler Scanning (Erection Phase):
Using an ultrasound probe, the physician measures:

• Arterial inflow (peak systolic velocity)
• Venous outflow (end diastolic velocity)
• Erection hardness and duration
  These numbers help identify whether ED is due to arterial insufficiency or venous leakage.

 4. Post-Test Monitoring:
Erections typically subside within an hour. If not, the clinic may administer a reversal agent or monitor you until detumescence occurs.

Is It Safe and Painful?

• The test is generally safe and well tolerated
• Mild discomfort may be felt during the injection, but it is brief
• Side effects are rare but may include prolonged erection (priapism)—managed immediately by clinic staff if needed

What Do the Results Tell You?

The Penile Doppler results offer critical data for personalized ED treatment:

• Normal arterial inflow and low outflow: Likely non-vascular or psychogenic ED
• Low arterial inflow: Arterial insufficiency (possible early vascular disease)
• High venous outflow: Venogenic ED, or "venous leak"
• Normal vascular findings: Consider hormonal, neurological, or psychological causes

These findings help your urologist select the most appropriate treatment—be it medications, injections, shockwave therapy, or implant surgery.
