Erectile Dysfunction: Causes, Treatments, and Diagnostic Tests

Erectile dysfunction 2

Hello Dr.
Hsu, thank you for your response.
However, I find that while watching adult films, I do feel stimulated, but the hardness of my erection is consistently insufficient.
I do experience nocturnal erections, but my morning erections and those during sexual activity are not satisfactory.
Even when I do achieve an erection, it often lacks firmness or quickly becomes soft.
Sometimes, during sexual intercourse, even if I tightly grip the base of my penis, I cannot achieve a firm erection.
What treatment options are available for this condition? Additionally, you mentioned "penile erection Doppler ultrasound"; do major hospitals offer this type of examination? What is the process for the examination? Thank you, Dr.
Hsu.

Hello, the hardness of an erection must be measured objectively using instruments.
If it is indeed insufficient, further clarification is needed to determine the underlying cause, whether it is arterial, venous, neurological, purely psychological factors, or simply insufficient stimulation.
It cannot be diagnosed solely based on your subjective statement of "not hard enough." Penile Doppler ultrasound is typically only available at major hospitals or medical centers, and it is usually performed by urologists who have undergone specialized training.
You can start by calling the urology department for inquiries.
If there are any details that are not clear, feel free to ask again, and we can discuss and research further.
The Taitung Hospital of the Department of Health, Executive Yuan, cares about your urological health.
Director Xu Wei-kai.

More Info

Erectile dysfunction (ED) is a common condition that affects many men at various stages of life. It is characterized by the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. Understanding the causes, treatments, and diagnostic tests for ED is crucial for effective management.

Causes of Erectile Dysfunction
ED can arise from a variety of physical and psychological factors. Some common causes include:
1. Physical Causes:
- Cardiovascular Diseases: Conditions such as hypertension, atherosclerosis, and heart disease can impede blood flow to the penis, making it difficult to achieve an erection.

- Diabetes: High blood sugar levels can damage nerves and blood vessels, leading to erectile dysfunction.

- Hormonal Imbalances: Low testosterone levels can affect libido and erectile function.

- Neurological Disorders: Conditions like multiple sclerosis or Parkinson's disease can interfere with nerve signals from the brain to the penis.

- Medications: Certain medications, including those for high blood pressure, depression, and anxiety, can have side effects that contribute to ED.

2. Psychological Causes:
- Anxiety and Stress: Performance anxiety or stress related to work or personal life can hinder sexual arousal.

- Depression: Mental health issues can significantly impact sexual desire and function.

- Relationship Issues: Problems with a partner can lead to emotional distress that affects sexual performance.

Treatments for Erectile Dysfunction
Treatment options for ED vary depending on the underlying cause. Some common treatments include:
1. Lifestyle Changes: Improving diet, exercising regularly, quitting smoking, and reducing alcohol consumption can enhance overall health and improve erectile function.

2. Medications: Oral medications such as sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra) are commonly prescribed to help achieve an erection by increasing blood flow to the penis.

3. Therapy: If psychological factors are contributing to ED, counseling or therapy may be beneficial. This can include cognitive-behavioral therapy or couples therapy.

4. Vacuum Erection Devices: These devices create a vacuum around the penis, drawing blood into it and helping to achieve an erection.

5. Penile Injections or Suppositories: Medications can be injected directly into the penis or inserted as a suppository to facilitate an erection.

6. Surgery: In severe cases, surgical options such as penile implants may be considered.

Diagnostic Tests for Erectile Dysfunction
To determine the underlying cause of ED, healthcare providers may recommend several diagnostic tests:
1. Physical Examination: A thorough physical exam can help identify any physical causes of ED.

2. Blood Tests: These tests can check for conditions like diabetes, hormone levels, and cholesterol levels.

3. Urinalysis: This test can help identify signs of diabetes or other underlying health conditions.

4. Ultrasound: A penile Doppler ultrasound can assess blood flow to the penis. This test is often performed after injecting a medication that causes an erection.

5. Nocturnal Penile Tumescence (NPT) Test: This test measures erections that occur during sleep to determine if the ED is due to psychological or physical causes.

Conclusion
If you are experiencing difficulties with erectile function, it is essential to consult a healthcare professional for a comprehensive evaluation. They can help identify the underlying causes and recommend appropriate treatments tailored to your specific needs. Additionally, many hospitals and clinics offer diagnostic tests, including penile Doppler ultrasound, to assess erectile function. Addressing ED can significantly improve quality of life and overall well-being, so seeking help is a vital step.
