Treatment and prevalence of erectile dysfunction after prostatectomy.
Erectile dysfunction after prostatectomy is common because surgery can damage the erection nerves, but most men improve significantly within a year.

Erectile dysfunction after prostatectomy is common: removing the prostate for cancer can damage the nearby nerves that control erections, and around 85% of men report erection difficulties in the period following surgery. The encouraging news is that most men improve significantly within a year, effective treatments exist, and structured penile rehabilitation is now considered standard care.
A radical prostatectomy removes the prostate gland to treat prostate cancer. Because the nerves responsible for erections run right alongside the prostate, they can be bruised or removed during surgery — which is why ED is one of the most common complications and why recovery takes patience.
How common is ED after prostatectomy?
Reported rates vary widely — studies cite anywhere from 14% to 90% — because of differences in surgical technique, patient age and how ED is defined. A commonly cited figure is that about 85% of men experience erection difficulties after the procedure, and nearly all men have at least some ED in the first few months. The wide range reflects how individual recovery is, not uncertainty about whether the problem is real.
The recovery timeline
Recovery of erectile function is usually gradual. Most men see meaningful improvement within a year or so of surgery, and for some it can take up to two years to return to regular erections. Nerve-sparing surgical techniques, which aim to preserve the erection nerves, have improved outcomes — though even with them, ED can persist for a significant time. Setting realistic expectations is important: the absence of erections in the early months does not mean function will not return.
Treatments for ED after prostatectomy
Several effective treatments are available, and they are often combined as part of a rehabilitation plan:
| Treatment | How it helps |
|---|---|
| Oral medications (PDE5 inhibitors) | Improve blood flow to the penis to facilitate an erection |
| Penile injections | Medication injected into the penis to produce an erection |
| Vacuum erection devices | Draw blood into the penis mechanically, drug-free |
| Penile implants | A surgical device for men who do not respond to other options |
Vacuum erection devices in particular are a useful drug-free option during recovery, as we explain in our article on vacuum pumps for ED. Oral medications like Viagra are frequently used too, though their effectiveness after surgery depends heavily on whether nerves were spared.
Penile rehabilitation and the emotional side
Penile rehabilitation — a structured program of treatments started early to maintain blood flow and tissue health — is now considered the standard of practice after radical prostatectomy. Just as important is the emotional dimension: ED after cancer treatment can be distressing, and psychosocial support such as counseling and support groups helps men and their partners cope. A holistic plan that addresses both the physical and the emotional aspects gives the best chance of recovery.
Work with your healthcare provider
Because outcomes vary so much between individuals, the right approach is a tailored plan developed with your healthcare provider. If your treatment involved radiation rather than, or in addition to, surgery, see our related article on whether Viagra works after prostate radiation.
