ED After Prostate Surgery: What to Expect

Why prostate surgery affects erections

The nerves responsible for triggering an erection run in close proximity to the prostate gland, in bundles on either side of it. During a radical prostatectomy (surgical removal of the prostate, usually for prostate cancer), surgeons aim to preserve these nerve bundles wherever it's oncologically safe to do so — known as a "nerve-sparing" approach. Even with nerve-sparing surgery, the nerves are handled and can be temporarily bruised or stretched, and full nerve function typically takes time to return, if it returns fully at all. When nerve-sparing isn't possible because of the cancer's location or extent, erectile difficulties are typically more pronounced and less likely to substantially improve without help.

What recovery generally looks like

Every person's recovery differs based on age, pre-surgery erectile function, the extent of surgery, and whether one or both nerve bundles were preserved, but some general patterns are common:

• Erectile difficulties immediately after surgery are expected, even with successful nerve-sparing surgery
• Gradual improvement can continue for many months, and sometimes over a year or more, as nerves heal
• Some men regain erectile function close to their pre-surgery baseline; others experience a lasting change that needs ongoing management
• Younger men and those with good erectile function before surgery generally have a better chance of recovery, though outcomes still vary considerably from person to person

Because nerve healing is slow, it's important to have realistic expectations and not to judge progress too early or measure it against someone else's timeline.

Penile rehabilitation

Many urology teams recommend a structured approach sometimes called "penile rehabilitation," starting soon after surgery, with the aim of maintaining blood flow and tissue health in the penis while nerves are healing. This might involve:

• Scheduled use of PDE5 inhibitor medicines, as prescribed and directed by your surgical team
• Vacuum erection devices, which draw blood into the penis mechanically
• In some cases, other prescribed treatments to support blood flow to the area

The specific rehabilitation plan, timing, and any medicine involved should always be decided by your treating urologist or surgical team, since they know your surgical details, cancer treatment plan, and overall health. This isn't something to self-manage. If PDE5 inhibitor medicines are part of your plan, remember they are Schedule 4 Prescription Only Medicines requiring a valid prescription, and they must never be combined with nitrate medicines — make sure your full medical team, including any other prescribers, is aware of everything you're taking.

Working with your surgical and urology team

Your urologist and surgical team are your primary resource throughout this process, because they understand exactly what was done during your surgery and how it affects your individual recovery. It's worth:

• Attending all scheduled follow-up appointments, even once you feel physically recovered
• Asking directly about expected timelines and what "normal" progress looks like for your specific surgery
• Reporting any new symptoms, including urinary changes, alongside erectile concerns
• Asking about referral to a specialist continence or sexual health service if extra support would help

The emotional side of recovery

Prostate cancer treatment and its effects on sexual function can understandably affect mood, self-image, and relationships, on top of everything else involved in cancer treatment and recovery. It's common, not a sign of weakness, and support is available — many hospitals and cancer support organisations offer counselling specifically for men recovering from prostate cancer treatment, and your GP can also help coordinate this support.

Looking beyond the immediate recovery period

If erectile function hasn't returned to a level you're satisfied with once initial healing is complete, there are still options to discuss with your urologist, ranging from ongoing medicine use to other treatments suited to nerve-related erectile difficulty. This is a genuinely individual conversation that depends on your surgical history and general health, so it's best had directly with your specialist rather than guessed at from general information. You can also read general background on causes and treatment approaches for erectile difficulties on our erectile dysfunction page, though your urology team's guidance takes priority given your surgical history.

The takeaway

Erectile difficulties after prostate surgery are common and largely explained by the close relationship between the prostate and the nerves controlling erections. Recovery is typically gradual, varies significantly between individuals, and is best supported by close, ongoing involvement with your urology and surgical team, who can tailor a rehabilitation plan and monitor progress over the months and years that follow.
