Does Prostate Cancer Treatment Cause Erectile Dysfunction?

Understanding the Link Between Prostate Cancer Treatment and Erectile Dysfunction

If you’ve been diagnosed with prostate cancer, concerns about erectile dysfunction (ED) are completely normal—and very common. Many men ask, “Will I still be able to have sex after treatment?” or “How long will it take for erections to return?”

The honest answer is that some treatments for prostate cancer can affect sexual function, but the degree and duration vary from person to person. With the right surgical technique, expert care, and supportive therapies, many men regain their ability to have satisfying sexual experiences.

Dr. David B. Samadi, a world-renowned prostate surgeon and urologic oncologist, has helped thousands of men navigate this journey with confidence. Here’s what you need to know.

Why Does Erectile Dysfunction Happen After Prostate Cancer Treatment?

The prostate is located close to key nerves and blood vessels that control erections. During surgery or radiation therapy, these delicate structures can be affected—leading to temporary or, in some cases, long-term erectile dysfunction.

Common causes include:

• Nerve damage from prostatectomy
  
  
• Reduced blood flow after radiation
  
  
• Pelvic muscle changes post-treatment
  
  
• Psychological stress or anxiety
  
  

Which Prostate Cancer Treatments Affect Erections Most?

1. Radical Prostatectomy (Surgery)

• Surgical removal of the prostate may affect the neurovascular bundles on either side.
  
  
• The impact depends on:
  
  
• Whether nerve-sparing surgery is performed
  
  
• Your age and pre-surgery erectile function
  
  
• Overall health and lifestyle
  
  

Dr. Samadi’s SMART (Samadi Modified Advanced Robotic Technique) approach is designed to preserve these critical nerves, offering a better chance of recovering erectile function.

2. Radiation Therapy

• Radiation can damage the nerves and blood vessels around the prostate over time.
  
  
• ED may develop gradually—often months or years after treatment.
  
  

3. Hormone Therapy

• Androgen deprivation therapy (ADT) lowers testosterone, which can reduce libido and cause difficulty achieving erections.
  
  

How Common Is ED After Prostate Cancer Treatment?

It’s estimated that 30–80% of men experience some level of erectile dysfunction after treatment, depending on the type of therapy and individual health factors.

However, the majority of men do regain function, especially with nerve-sparing surgery and the right recovery plan.

Can Erectile Function Return?

Yes—many men recover over time, particularly those who had good function before treatment and received expert surgical care.

Recovery timelines:

• 3–6 months: Some men begin seeing improvement
  
  
• 6–12 months: Continued progress for many
  
  
• 12–24 months: Full recovery possible in certain cases
  
  

How Dr. Samadi Helps Patients Recover Sexual Function

Dr. Samadi takes a proactive approach to protecting and restoring erectile function:

• Nerve-sparing technique: His SMART surgery minimizes trauma to surrounding structures.
  
  
• Early rehabilitation: He often recommends early intervention, such as:
  
  
• Oral medications (e.g., Viagra, Cialis)
  
  
• Vacuum erection devices
  
  
• Penile injections or suppositories
  
  
• Pelvic floor exercises
  
  
• Personalized care: Recovery plans are customized for each patient’s needs and goals.

Erectile dysfunction is more than a physical issue—it affects confidence, relationships, and overall well-being. Dr. Samadi encourages open, judgment-free conversations about sexual health so men can get the support and solutions they deserve.
