Erectile Dysfunction


Erectile dysfunction (ED) is a common condition affecting a man’s ability to achieve or maintain an erection sufficient for sexual intercourse.

Erectile dysfunction was often referred to as impotence in the past, but ED is used now to more accurately describe the condition where achieving or maintaining an erection for sexual activity is difficult.

While it’s more prevalent among older men, ED can happen at any age.

Erectile dysfunction symptoms include:

  • Struggling to obtain an erection: Experiencing difficulties in obtaining an erection during one or several attempts, even with the intention to engage in sexual activity.
  • Challenges in sustaining an erection: Managing to initiate an erection but finding it challenging to keep it as long as desired for sexual activity.
  • Decrease in libido: Noticing a decline in sexual desire or interest, which may be associated directly with the emotional or psychological distress resulting from ED.

The implications of ED extend far beyond sexual health alone – the impact can be seen on a man’s emotional and psychological well-being and in relationships, too.

Erectile Dysfunction


The causes of ED are complex and can include both physical and psychological aspects.

Physical Causes of Erectile Dysfunction

Cardiovascular diseases: Conditions that affect the heart and blood vessels, such as atherosclerosis, can impede blood flow to the penis, crucial for achieving an erection. Atherosclerosis is characterized by the hardening and narrowing of the arteries due to plaque buildup on the artery walls.

Diabetes: High glucose, or blood sugar, levels can damage nerves and blood vessels, making it more challenging to achieve or maintain an erection.

Hypertension: Hypertension, or high blood pressure, can harm blood vessels, including those leading to the penis, which can affect erectile function.

High cholesterol: Elevated cholesterol levels can lead to atherosclerosis, which narrows and hardens arteries, limiting blood flow and potentially causing ED.

Obesity: Being overweight or obese can increase the risk of vascular disease and diabetes, two major contributors to ED. Obesity can also lower testosterone levels, impacting sexual function.

Neurological conditions: Disorders that affect the nervous system, such as Parkinson’s disease, multiple sclerosis, and spinal cord injuries, can disrupt signals between the brain and the penis necessary for an erection.

Side effects of medications: Many medications, including antidepressants, antihypertensives, and medicines for prostate conditions, can have side effects that include ED.

Hormonal imbalances: Hormonal issues, such as thyroid problems, can affect erectile function.

Psychological Causes of Erectile Dysfunction

Stress: The body’s response to stress can interfere with sexual arousal and erectile function.

Anxiety: Performance anxiety, or fear of sexual failure, can trigger a cycle of ongoing ED. Generalized anxiety disorders may also contribute to the problem.

Depression: Depression can lead to a decrease in libido. This can affect a person’s ability to experience pleasure, including sexual pleasure.

Relationship Issues: Emotional strain due to relationship problems can affect sexual function.

The Connection Between Low Testosterone and Erectile Dysfunction

Low testosterone (low T) can be a contributing factor to ED. Testosterone is a key hormone in the male body, influencing libido and erectile function. While not all cases of ED are linked to low T, men with lower testosterone levels may experience a decrease in sexual desire and a higher incidence of erectile dysfunction.

Diagnosing low T involves a simple blood test. If low levels are detected, hormone replacement therapy might be recommended as part of the treatment plan for ED.


Treating ED involves a comprehensive approach that addresses both the physical and psychological aspects of the condition. Some treatment options for ED include:

1. Lifestyle modifications

Changes to one’s lifestyle can have a significant impact on improving symptoms of ED, including:

  • reducing alcohol intake
  • quitting smoking
  • exercising regularly
  • maintaining a healthy diet

2. Medications

Oral type 5 inhibitors, commonly known as PDE5 inhibitors, are the most popular choice for men experiencing ED. These medications work by enhancing the effects of nitric oxide, a natural chemical your body produces that relaxes muscles in the penis. This relaxation allows for increased blood flow into the penile tissues, facilitating the achievement and maintenance of an erection when combined with sexual stimulation. Examples of these medications include:

  • sildenafil (Viagra)
  • tadalafil (Cialis)
  • vardenafil (Levitra)

3. Mental health support

Seeking psychological support is a critical component for men whose ED is rooted in factors such as stress, anxiety, depression, or relationship problems. Working with a licensed mental health practitioner can help to address these issues, moving toward the goal of improving ED symptoms and enhancing sexual intimacy.

4. Vacuum erection devices

These devices consist of a tube placed over the penis with a pump to create a vacuum. The vacuum pulls blood into the penis, inducing an erection. A band placed at the base of the penis maintains the erection. Vacuum devices are effective for many men and can be used in combination with other treatments.

5. Surgical options

When other treatments are ineffective, surgical options may be considered.

  • Penile implants: Devices are surgically placed into the sides of the penis. These implants can be inflatable or malleable rods, allowing for manual adjustment to achieve an erection.
  • Vascular surgery: Though rarely recommended, it’s considered for younger men with specific blood vessel injuries.

The treatment of ED is highly personalized and includes addressing underlying health conditions that may be contributing. Working closely with your doctor will help you identify potential causes and choose the best treatment plan for you. With the right strategy, most men can experience improved erectile function.


Can lifestyle changes really improve ED?

Yes, lifestyle changes can absolutely impact ED. Healthy weight management, regular physical activity, and a balanced diet can improve cardiovascular health. Reducing stress and avoiding substances like tobacco and excessive alcohol can also make a big difference in improving erectile function.

Are ED medications safe for everyone?

While ED medications are safe for most men, they’re not the best choice for everyone, especially those with certain heart conditions or who take nitrate drugs. Be sure to have your doctor’s approval before starting any ED medication.

How do I know if my ED is caused by low T?

Symptoms of low T include reduced sex drive, mood changes, fatigue, and difficulty concentrating, alongside ED. A blood test can accurately measure your testosterone levels to determine if low T is contributing to your ED.
