What Researchers Did
Researchers conducted a systematic review of randomized controlled trials to evaluate penile rehabilitation and treatment options for erectile dysfunction following radical prostatectomy and radiotherapy.
What They Found
They found that while animal studies support phosphodiesterase type 5 inhibitors (PDE5i) for erectile dysfunction after cavernous nerve damage, human study results are contradictory. Evidence for non-medical treatments like vacuum device therapy, hyperbaric oxygen therapy, yoga, aerobic, or pelvic floor training was scarce, and clear guidelines for penile rehabilitation are not yet available.
What This Means for Canadian Patients
Canadian patients experiencing erectile dysfunction after prostate cancer treatments like radical prostatectomy or radiotherapy may find limited clear guidance on effective penile rehabilitation strategies. They should discuss available options with their healthcare providers, understanding that current evidence for many treatments, including PDE5i and non-medical therapies, is often contradictory or scarce.
Canadian Relevance
This systematic review does not have a direct Canadian connection.
Study Limitations
The primary limitation identified by the review is the scarcity of robust evidence and contradictory results from human studies regarding penile rehabilitation and treatment options.
