Erectile Dysfunction After Prostate Cancer Surgery: Treatment Paths
Why does erectile dysfunction occur after radical prostatectomy, and does it recover? Penile rehabilitation, medication and when a penile implant comes up — an informative guide.
Prostate cancer surgery (radical prostatectomy) is a life-saving treatment; yet an important problem many men face afterwards is erectile dysfunction. Overshadowed by surviving cancer, the subject often goes unspoken. In reality, post-operative sexual function is a medical matter that can be managed with a structured plan.
Why does prostate surgery affect erections?
The nerve bundles responsible for erection run immediately alongside the prostate. In radical prostatectomy the safe removal of the tumour comes first; even when the nerves are spared, their function can be affected by surgical trauma, stretching or the tumour's location. In the months after surgery, reduced nerve signalling to the penis can lower tissue oxygenation and lead to structural changes over time.
If nerve-sparing surgery was performed, will erections return?
In a proportion of patients operated on with nerve-sparing technique, erections can recover gradually over months. The process varies from person to person and may extend to twelve to twenty-four months. The main factors are age, pre-operative erectile function, the degree of nerve preservation and accompanying conditions such as diabetes or vascular disease. Where the nerves could not be preserved, spontaneous recovery is unlikely, and the treatment plan should be clarified earlier.
What is penile rehabilitation?
Penile rehabilitation is a structured programme applied after surgery to preserve the oxygenation and elasticity of penile tissue. Oral medication, vacuum devices and, where needed, injection therapy can be used within the programme. The aim is to limit tissue shrinkage and permanent structural change while nerve recovery is awaited. An early start is generally preferred; content and duration are tailored to the patient.
Which treatment options are used?
- Oral medication (PDE5 inhibitors): the first step; can be effective when nerve function is partly preserved.
- Vacuum erection devices: used both for rehabilitation and as support before intercourse.
- Injection therapy: an effective option when oral medication does not work.
- Penile prosthesis: the surgical option considered when the other steps do not provide adequate benefit.
When does a penile implant come up?
If erections have not returned despite an adequate waiting and rehabilitation period, and medication and injections have proved insufficient, a penile implant is considered. Men who have undergone prostate cancer surgery are among the groups reporting the highest satisfaction with penile implants: the cause of the problem is clear, and the implant restores function reliably. The decision is made at an appropriate point in oncological follow-up, together with the patient and, where needed, the oncology team.
Do not hesitate to raise this with your doctor
Bringing up sexual health after cancer treatment is not ingratitude or a luxury; it is a legitimate part of quality of life. Talking about the problem is the first step towards solving it. A well-timed andrology assessment clarifies which step is right for you.
