Undergoing treatment for prostate cancer is a major life event and while survival rates are high, many men are left with erectile dysfunction as a lasting side effect. This can feel frustrating, isolating, and overwhelming. There are effective, non-invasive tools to support your recovery.
One of the most important and often underutilised tools 
is the Vacuum Erection Device (VED). Also known as a penis pump, the VED is not just for sexual activity – it plays an important part in penile rehabilitation after prostate cancer treatment.
Why does erectile dysfunction happen after prostate cancer?
- Post surgery
Radical prostatectomy (removal of the prostate gland) often leads to erectile dysfunction even when nerve-sparing techniques are used. The nerves that control erections are delicate and can be temporarily or permanently affected during surgery.
- Radiation treatment
Radiation therapy (external beam or brachytherapy) may cause gradual damage to blood vessels and nerves, leading to delayed onset erectile dysfunction over months or years.
In both cases, the result is reduced blood flow and difficulty achieving or maintaining erections making early intervention essential.
It is more than just a treatment for erectile dysfunction
While commonly used to achieve erections for sexual intercourse, pumps also serve a crucial medical role in preserving penile tissue health after prostate cancer treatment. This process is known as penile rehabilitation.
What is penile rehabilitation and why is it important?
Penile rehabilitation refers to a proactive strategy aimed at maintaining erectile tissue health, blood flow, and function following prostate cancer treatment. Without regular erections, either natural or assisted, the penis receives less oxygen-rich blood, increasing the risk of:
- Tissue scarring (fibrosis)
- Loss of length or girth
- Long-term erectile dysfunction
Regular use, even if not for sexual activity, helps keep the erectile tissue functional until natural erections potentially return.
When should you start using a pump after surgery or radiation?
Most clinics recommend starting pump therapy about 4 to 6 weeks after radical prostatectomy, once the surgical site has healed.
For radiation patients, pump use may begin as soon as ED symptoms appear, or even pre-emptively in some cases.
NOTE: Always follow your healthcare provider’s guidance on when and how to begin.
How does a penis pump work?
A pump consists of:
- A plastic cylinder that fits over the penis
- A manual or battery-powered pump that creates negative pressure
- A constriction ring (optional) placed at the base of the penis to maintain the erection
How it helps rehab:
- The vacuum draws blood into the penis
- This mimics a natural erection and delivers oxygen to the tissues
- When used regularly, this supports healing and function
How often should you use a pump for rehabilitation?
Typical rehabilitation protocols recommend:
- Daily or 3–5x per week use
- Hold the erection for 1-2 minutes to allow oxygenation and repeat
- Use a water-based lubricant for comfort and safety
This routine can be maintained for 6–12 months or longer, depending on your recovery timeline and treatment plan.
Can a pump be combined with other ED treatments?
Yes! Pumps are often part of a multimodal approach to ED recovery:
- With oral medications (Viagra, Cialis) to boost natural blood flow
- With penile injections if additional firmness is needed
- With pelvic floor therapy to improve muscle control and function
Is a pump right for every man?
Pumps are generally safe and effective for most men, but may not be suitable if you have:
- Severe bleeding disorders
- Significant curvature (Peyronie’s disease)
- Certain blood clotting conditions

What to look for in a medical-grade pump
When choosing a pump, make sure it’s:
- Clinically approved
- Made of medical-grade materials
- Customisable ring sizes and pressure control
- Covered by a warranty or support program
Avoid novelty or non-medical “penis pumps” sold online without clinical backing.
If you’re recovering from prostate cancer treatment, you don’t have to accept erectile dysfunction as a permanent outcome. Vacuum erection devices offer a powerful, non-invasive way to support your sexual recovery…not just in the bedroom, but in your overall sense of self.
