This is something to take to a clinician. The Atlas can tell you what is known about radical prostatectomy & erectile dysfunction in general. It cannot tell you what is happening in your body, and the difference matters most for exactly the symptoms that bring people to this page.
Radical prostatectomy removes the entire prostate and seminal vesicles to cure localized prostate cancer. Because the cavernous nerves run on the posterolateral prostate surface, the operation routinely injures erectile function. Walsh's anatomic nerve-sparing technique (1982) and later robotic approaches improved outcomes, but recovery is slow (12-24+ months of neuropraxia) and incomplete: realistic potency-recovery figures vary enormously by age, baseline function, nerve-sparing status, and surgeon volume. 'Penile rehabilitation' (early PDE5 inhibitors, sometimes injections or a vacuum device) is widely practiced to preserve cavernosal tissue, though high-quality RCT support for it is surprisingly weak.
Curing the cancer is the easy part; getting the erection back is the long, uncertain part.
What people take it for
What it is taken for. Approval, where it exists, covers only some of these.
- Localized prostate cancer
- Intermediate/high-risk or younger patients favoring surgery over radiation
- Penile rehabilitation
- Early PDE5 inhibitors, intracavernosal injection, or vacuum device after nerve-sparing surgery
How it works
Even with meticulous bilateral nerve-sparing, the cavernous nerves undergo traction, thermal, or ischemic injury during dissection, producing neuropraxia, a temporary or permanent conduction failure. Without nocturnal/spontaneous erections, the cavernosal smooth muscle becomes hypoxic and can undergo apoptosis and fibrosis (collagen deposition, penile shortening). The rationale for penile rehabilitation is to maintain oxygenation and tissue health during the months of nerve recovery so that, if the nerves recover, the erectile machinery is still intact to respond.
What the consent conversation often understates
Three realities are frequently soft-pedaled. First, even bilateral nerve-sparing in expert hands does not guarantee return of erections sufficient for intercourse; outcomes depend heavily on baseline function and age, and many series overstate success by counting 'erections with PDE5 inhibitors' as recovery. Second, ejaculation is gone permanently, the prostate and seminal vesicles are removed, so orgasm becomes dry. Third, the much-promoted 'penile rehabilitation' protocols rest on a thin RCT foundation; the largest trials (e.g., scheduled vs on-demand PDE5 use) have not consistently shown that rehabilitation changes long-term unassisted potency, even though it is near-universal practice.
Safety in detail
This is a major oncologic surgery with documented, often permanent effects on erectile and ejaculatory function and on continence. Decisions require evaluation by a qualified urologic oncologist and a frank pre-operative discussion of realistic sexual outcomes.
What people get wrong
Often saidRobotic surgery means you keep your erections
ActuallyThe robot improves visualization but does not change the fundamental nerve-injury problem; potency still depends on age, baseline, and nerve-sparing.
Often saidPenile rehabilitation is proven to restore function
ActuallyIt is standard, biologically rational, and may help tissue health, but RCT evidence that it restores unassisted erections is weak and inconsistent.
Who profits, and who pushes back
Nobody is named here yet, because we have not done that work on this entry. Read that as unfinished. Somebody almost certainly sells this, and somebody almost certainly disputes it. Assume both until we have checked.
What we do not know
- Whether any penile-rehabilitation protocol improves long-term unassisted potency.
- Best timing and modality (PDE5 vs injection vs vacuum) remain unsettled.
At a glance
- Erectile nerve location

- Recovery window
- 12-24+ months (neuropraxia)
- Ejaculation after RP
- Permanent dry orgasm (no prostate or seminal vesicles)
- Rehab RCT support

What this entry does not yet cover
What follows is unfinished work on our side, not a finding about Radical Prostatectomy & Erectile Dysfunction. A short entry is not a safe entry.
- Timeline. We have not built the dated record of research and regulatory events.
- Cost and market. We have not documented what it sells for or who sells it.
- Supply chain. We have not mapped where it is made.
- Who uses it. We have not documented the user groups.
- What could change. No forward-looking summary yet.
- How it compares. We have not set it against the alternatives.
- Children and teenagers. We have not checked what is known about younger people.
- What can go wrong. We have not written the risk line for this one. Read the safety section below rather than treating its absence as reassurance.
