Overview
Male sexual response cycle has four phases: desire, arousal, orgasm and resolution.
There are multiple complex factors that are involved during a sexual response cycle.
Penis in a flaccid state is like any other organ in the body needing arterial blood flow into and venous blood flow out of the penis. The basic process of erection involves desire followed by increase in arterial blood flow to penis with arousal during which period the veins of the penis get engorged with no outflow of blood till the time ejaculation is achieved.
Understanding ED Types
There are several types of ED, which may require different types of treatment in order to rectify the situation.
Vasculogenic Erectile Dysfunction
Vasculogenic erectile dysfunction occurs when the arteries and veins that carry blood through the penis no longer carry blood correctly. This can occur because of narrowing of the arteries and veins or blockages within them.
Neurogenic Erectile Dysfunction
Neurogenic ED results from impairment to the nervous system. When the nervous system is damaged in any way, it can prevent the usual response to stimulation or arousal. As a result, you may be unable to maintain an erection.
Hormonal Erectile Dysfunction
Hormonal ED occurs because of a disruption in normal hormone function. Hormones can have a significant impact on arousal and erection, and when hormones are out of balance, it can make it more difficult to get or maintain an erection.
Psychological Erectile Dysfunction
Psychological ED stems from psychological, rather than physical, causes. It can occur due to trauma, stress, or negative sexual experiences.
Symptoms of Erectile Dysfunction
Erectile dysfunction is seen across all age groups. There are two main issues that are encountered in clinical practice. First is the inability to achieve an erection. The second is inability to sustain or maintain an erection. Learn more about the full signs and risk factors of ED.
One of the causes of inability to achieve an erection is poor circulation with inadequate arterial blood supply to the penis during an erection.
In our local practice, a large number of patients present with this problem of maintain an erection. One of the major vascular causes of inability to sustain or maintain an erection is venous leak.
Causes and Risk Factors of Erectile Dysfunction
Erectile dysfunction is the inability to achieve or maintain an erection firm enough to have sexual intercourse. The disorder is highly age-dependent, as the combined prevalence of moderate to complete erectile dysfunction rises from approximately 22% at age 40 to 49% by age 70. Although less common in younger men, erectile dysfunction still affects 5%-10% of men below the age of 40.
- There are multifactorial organic or psychological causes of erectile dysfunction. These may include high blood pressure, high cholesterol, diabetes, peripheral vascular disease, excessive stress, obesity, family history of atherosclerosis, smoking, anxiety and hormonal disorders.
How Is Erectile Dysfunction Diagnosed?
Accurate diagnosis is essential because treatment recommendations vary depending on the underlying cause.
Medical History
Your doctor will discuss symptoms, duration, severity, lifestyle factors, medical conditions, and current medications.
Physical Examination
A physical examination helps evaluate vascular, hormonal, and general health factors that may contribute to ED.
Blood Tests
Blood tests may be performed to assess:
- Testosterone levels
- Blood sugar levels
- Cholesterol levels
- Other metabolic markers
Radiological Tests
- Penile Doppler Ultrasound: A Penile Doppler Ultrasound is one of the most useful screening methods for evaluating blood flow to the penis, which may identify vascular causes of erectile dysfunction such as Arterial insufficiency or Venous leak. The scan has a high degree of accuracy and is a useful test to guide further management in conjunction with the history.
- Penile Angriography: This is minimally invasive procedure used to assess penile blood flow and identify arterial abnormalities linked to erectile dysfunction.
- Cavernosography: This is an invasive test done in special circumstances.
Treatment of Vasculogenic Erectile Dysfunction
Erectile dysfunction is a complex disorder with many causes. Multiple treatment options are available depending on the underlying cause. For patients with vascular cause of erectile dysfunction, the following treatments are include:
- Medical therapy: there are multiple medications available that are very effective in treating physical symptoms.
- Surgical intervention
- Endovascular interventional procedures: These latter are day surgery procedures done under sedation with quick recovery within a day . There are two categories of endovascular procedures available. These are both done at same time in most patients in a single session of treatment of about 60-90 minutes.
- Arterial inflow procedure (angioplasty/stenting): these involve access using tiny 2 mm incision in the artery of the groin or wrist. Small tubes called catheters are advanced into the arteries all the way to check if there is any blockage in arterial flow to the penis. The blood flow is opened up as required using balloon dilatation or stenting of blocked arteries. Occasionally, there are arteriovenous connections called fistula seen on angiogram stealin arterial blood from the penis that can be treated at same time.
- Venous leak embolization: this involves direct access of one of the draining veins under the skin of penis under ultrasound guidance. The site of leak is identified in the pelvis and occluded using surgical glue or occasionally dedicated occlusive coils using the same approach. We also treat other issues such as varicolece and benign prostate hyperplasia apart from erectile dysfunction.

Frequently Asked Questions
Can Erectile Dysfunction be cured?
Can I prevent erectile dysfunction?
Here are some lifestyle choices and management options that can possibly decrease the risk of erectile dysfunction. For example, you may want to consider:
- Reducing alcohol and nicotine consumption
- Managing any ongoing health conditions, including heart disease or diabetes
- Managing symptoms of anxiety or depression
However, in some cases, erectile dysfunction may be beyond your control. When medications increase the risk of erectile dysfunction, for example, you may need to maintain your regular medication schedule until you have a chance to talk to your doctor and discuss switching medications. Further medical treatment can also improve erectile health.
Can Diabetes cause Erectile Dysfunction?
Is Erectile Dysfunction a sign of heart disease?
Could Erectile Dysfunction be related to blood flow problems?
Many people think of erectile dysfunction primarily as a sexual health issue. However, for some men, ED may be linked to an underlying vascular condition affecting blood flow. An erection requires healthy arteries to deliver blood into the penis and healthy veins to retain that blood long enough to maintain an erection. Conditions such as diabetes, high blood pressure, high cholesterol, smoking, and atherosclerosis can affect this process.
In some cases, erectile dysfunction may even serve as an early warning sign of cardiovascular disease. Because the penile arteries are smaller than coronary arteries, symptoms of reduced blood flow may appear in the penis before cardiovascular symptoms develop elsewhere in the body. Understanding whether poor blood flow is contributing to your ED may help determine whether vascular-focused treatment options should be considered.
What is a Venous Leak?
Which doctor should I see for Erectile Dysfunction?
Depending on the underlying cause, evaluation may involve specialists in men’s health, urology, endocrinology, or vascular and interventional medicine.
Which Erectile Dysfunction treatment is right for me?
Treatment depends on the cause of erectile dysfunction and individual patient circumstances.
Lifestyle Modification
Lifestyle changes are often recommended as a foundation for treatment.
Examples include:
- Smoking cessation
- Weight management
- Exercise
- Blood pressure control
- Diabetes management
These measures may improve both erectile function and overall cardiovascular health.
Oral Medications
Common medications include:
- Sildenafil (Viagra)
- Tadalafil (Cialis)
These medications are often effective for mild to moderate erectile dysfunction.
Surgical Intervention
Advanced Minimally Invasive Treatments
For selected patients with confirmed vascular causes of erectile dysfunction, minimally invasive image-guided procedures may be considered over surgical intervention. Endovascular interventional procedures are day surgery procedures done under sedation with quick recovery within a day . There are two categories of endovascular procedures available. These are both done at same time in most patients in a single session of treatment of about 60-90 minutes.
Venous Leak Embolization
This procedure may help selected men diagnosed with venous leak by reducing abnormal venous drainage.
Arterial Inflow Procedures
Men with reduced arterial blood flow may be candidates for arterial inflow procedures designed to improve circulation.
