“Let’s face it… EVERYONE in the room knows when you are struggling with ED. The PDDU provides answers to the question “WHY” do I have ED, “HOW” bad is my ED, and “WHAT” needs to be done to fix my ED forever?” ~ Dr. Lisbeth Roy


If you have concerns regarding your erectile function, a Doppler Ultrasound provides the answers. It allows us to find out WHY you are suffering from erectile dysfunction (ED), exactly HOW bad your ED is, and exactly WHAT we need to do to fix it forever!

What is a Doppler Ultrasound?

A Penile Duplex Doppler Ultrasound (PDDU) assesses the etiology (i.e., the cause) of your ED, determining specific details that we need to know to treat it effectively (such as whether you have an inflow or outflow type of ED, whether the ED is a symptom of a more serious illness or condition (such as atherosclerosis) or whether it is caused by localized factors (e.g., scar tissue in the penis). The PDDU is a form of ultrasound technology not unlike that used in pregnancy scans.

What can you expect from a PDDU scan? The first important fact is that we can perform it in-office, offering you immediate results.

Firstly, we inject a vasodilator (usually Tri-Mix) into your penis (with a tiny needle!) that helps to relax erectile muscles in your penis, dilating penile arteries, and causing an erection. The establishment of an erection is crucial in allowing us to perform the scan because ED is usually linked to blood flow issues.

Then, an ultrasound technician determines the direction and flow of blood in and out of the penis by running a small hand-held device called a transducer along the outside of your penis. The data created via the transducer scan immediately highlights and differentiates between different kinds of erectile dysfunction, alerting us to pinpoint underlying medical conditions and physiological triggers that may have caused it

The PDDU then allows us to create an ultrasound image of the inside of your penis, allowing us a birds’ eye view of exactly what is going on inside your body. We then use this visual data to ascertain the causes and severity of your erectile dysfunction, facilitating the creation of a customized treatment plan and a deeply effective blueprint that we will then utilize to resolve the issues that you are facing. You’ll be unlikely to receive this kind of ultrasonic, detailed technological approach from your primary care physician – we are specialists in sexual performance at the Doctors Studio which means that we can offer you insights that very few others can.

The biggest problem you will have in finding a resolution to your erectile dysfunction (ED), or other associated sexual problems is the lack of knowledge your doctor has about the many causes of ED, how to diagnose which one(s) are affecting you and what to do about it.

Your Penis…Is Incredible

When you look closely at the penis, particularly with an ultrasound scan, you can really appreciate what an incredible organ it is.

An erection is simple in its elegance, complex in its mechanical process, & incredibly pleasurable to experience!

An erection requires the rapid and efficient coordination of your arterial, venous, nervous, and capillary systems. Your erection originates in the brain, where sexual stimulation causes a nerve signal to stimulate the release of the neurotransmitter dopamine (often referred to as the ‘happy hormone’!).

The signal then continues via the parasympathetic nervous system (PNS) pathway to the penis (NB. the PNS controls homeostasis – the balance of the body at rest), at which point the smooth muscle of the arteries in the penis relax.

This relaxation allows blood to flow into the penis at an increased rate and pressure, causing the penis to harden. Once erect, orgasm and ejaculation are dependent on the regulatory actions of the sympathetic nervous system (SNS-which controls the body’s reactions to stimulation) and the contraction of pelvic bowel muscles. You might have noticed that the quantity of ejaculate volume created as you orgasm contributes significantly to the pleasure and intense feeling of ejaculation

The Studio team uses the Penile Duplex Doppler Ultrasound to scan your erect penis, determining the cause of your erectile dysfunction, and allowing an assessment of multiple performance benchmarks, such as decreased sensitivity, poor arterial blood flow, neurological compromise, the effect of back injuries or nerve impingement, and a wide range of other factors. With this comprehensive evaluation of the penis in its erect state, we can use the PDDU to get to the root of the cause of your ED.

A PDDU scan does not just scan the quality of blood flow in and out of your penis, but also allows a full assessment of the health of your prostate, testicles, and general pelvic area, all of which can contribute to the onset of ED. We can then talk you through all of the available treatment options to allow you so that we can restore you to full penile erectile health once again as rapidly as possible!

What it comes down to is this – sex should be incredible, fulfilling & satisfying experience – don’t let your ED deny you of that!

“MY HAT IS OFF TO MEN.  It is NO EASY FEAT to get and maintain an erection; though many make it look easy, more than 50% of all adult men struggle with erectile function.”  ~ Dr. Lisbeth Roy

ED as a Symptom of Disease

Did you know that ED can often be a symptom of a more serious underlying diseases, such as cancer, atherosclerosis, or Peyronie’s Disease?  

Many of these potentially life-threatening diseases can remain asymptomatic, sometimes for YEARS – and by the time physical symptoms such as pain do occur, serious physical damage may have occurred. ED might be your body’s early warning system so do not ignore it! A PDDU can alert us to the presence of these various dysfunctions & diseases, so why risk NOT checking it out? A small risk, yet one too important to ignore, is penile cancer, which affects around 1% of men in the US, with symptoms including:

  • Blisters or lesions on the penis
  • Wart-like or raised growth that bleeds, or smells badly
  • Presence of one or more lumps and swollen lymph nodes

If you feel that you are experiencing any of these symptoms, or even if ED remains your only symptom, you need to get checked out to rule out the possibility of a potentially life-threatening condition.

PDDU’s & Peyronie’s Disease

One condition that a PDDU scan has proven excellent in the detection of is Peyronie’s disease –  a condition that causes curvature of the penis.

Peyronie’s, also known as penile fibrosis, is the presence of fibrous scar tissue in the penis that can cause painful, bowed erections. It often begins as inflammation and grows into a hardened area (in the thick sheath of the penis called the Tunica Albuginea). This unpleasant condition inhibits the proper erection of a penis, but it is often confusing to know whether it has occurred due to injury or because of an underlying physiological issue. A PDDU scan makes clear the pathology, making subsequent treatment options far more efficient. Such knowledge is vital as, if left untreated, Peyronie’s can often cause irreversible damage.

Ultimately, no man should feel shy about seeking help for an ED. At the Doctors Studio, we have performed countless PDDU scans and helped countless men restore sexual function. Sometimes we have even discovered – and treated – potentially life-threatening conditions. Remember – a penile ultrasound could end up saving your life and at the very least allow us to treat your ED in a rapid and efficient way.

If you’ve been having any concerns whatsoever about ED, don’t wait – contact us today, and let’s get it fixed together. Regardless of the cause – whether it is psychological, hormonal, blood vessel-related, or neurological, we will get to the bottom of it.

Diagnostic Benefits of a PDDU:

  • Evaluation of dynamic blood flow to and from the penis
  • Detection of abnormalities of / affecting the penis (cancer, Peyronie’s Disease, scar tissue, etc.)
  • Diagnosis of arterial insufficiency
  • Detection of venous leakage
  • Quantification of blood flow abnormalities
  • Determination of whether large or small blood vessel disease is present
  • Predicts the response of your ED to vasodilation medications that enhance blood flow to the penis
