* a normal erection is mediated by three factors, adequate arteries, adequate venous system and an adequate set of nerves
Venous leak - the inability to trap blood in the penis
2 clinical tip offs to the presence of venous leak
- I've had years of normal erectile function and now no matter what kind of stimulation I get I can't maintain an erection
- the erection is position dependant, that is when the man is standing up and gravity is working with him trapping some more blood in the penis he does a better job of maintaining the erection and as soon as he lies on his back the erection goes away
What Is Venous Leakage? Ask a sexpert! Dr. Greg Broderick answers this question in the latest installment of this video series.
Understanding Venous Leak: A Unique Cause of Erectile Dysfunction
By Greg Broderick, Urologist at Mayo Clinic Florida
Erectile dysfunction (ED) is a condition that many men are familiar with, often advertised during prime-time television. Commonly understood as the inability to initiate or maintain an erection, ED can stem from various underlying causes. While aging and arterial issues are frequently blamed, there's a less-discussed culprit that affects men across all age groups: venous leak.

Understanding Venous Leak: A Unique Cause of Erectile Dysfunction
By Greg Broderick, Urologist at Mayo Clinic Florida
Erectile dysfunction (ED) is a condition that many men are familiar with, often advertised during prime-time television. Commonly understood as the inability to initiate or maintain an erection, ED can stem from various underlying causes. While aging and arterial issues are frequently blamed, there's a less-discussed culprit that affects men across all age groups: venous leak.
The Mechanics of a Normal Erection
To comprehend venous leak, it's essential to understand how a normal erection occurs. An erection is a complex process involving three critical components:- Adequate Arterial Flow: Blood must flow freely into the penis through the arteries. Upon sexual stimulation—whether physical touch or mental arousal—the arteries dilate, increasing blood flow significantly.
- Efficient Venous System: To achieve and maintain rigidity, the veins must trap the incoming blood within the penis. This trapping isn't due to traditional mechanical valves but rather a network of smooth muscle fibers arranged like a honeycomb. These sinusoids fill with blood, trapping it and building pressure.
- Healthy Nerve Function: Nerves trigger the response to sexual stimulation, coordinating the vascular changes necessary for an erection.
What is Venous Leak?
Venous leak, also known as venogenic erectile dysfunction, occurs when the veins fail to trap blood effectively within the penis. Even if arterial flow is sufficient, the inability to maintain blood within the penile tissue results in difficulty sustaining an erection.Identifying Venous Leak
Men with venous leak often present with specific symptoms:- Inability to Maintain an Erection: Despite adequate stimulation, the erection diminishes quickly. This is different from premature ejaculation, where the erection subsides after orgasm.
- Position-Dependent Erections: Some men notice that erections are better when standing due to gravity aiding blood trapping but worsen when lying down.
Diagnosis
A thorough evaluation by a healthcare professional is crucial. A Doppler ultrasound can assess blood flow within the penile arteries and veins, helping to distinguish between arterial insufficiency and venous leak.Management Strategies
Currently, there is no definitive cure for venous leak, but there are ways to manage the condition:- Medications: Phosphodiesterase type 5 inhibitors (PDE5 inhibitors) like Viagra®, Levitra®, and Cialis® can enhance arterial inflow. However, their effectiveness may be limited in cases of significant venous leak.
- Penile Injections: For more severe cases, intracavernosal injections can directly induce an erection by increasing arterial inflow.
- Constriction Rings: Using a constriction ring or elastic band at the base of the penis can help trap blood. It's imperative to use devices designed for this purpose to prevent injury. The band should be elastic and easily removable; metal rings or non-elastic materials pose significant risks, including tissue damage.
Important Precautions
- Safety First: Never use improvised devices like rubber bands or metal rings, as they can cause severe harm.
- Consult a Professional: Always seek advice from a qualified healthcare provider before starting any treatment.
Looking Ahead
Research continues into more effective treatments for venous leak. While management options are available, advancements in medical science may one day offer a cure.About the Author
