After a radical prostatectomy, erectile dysfunction usually lasts months to 2 years, and for some men it is permanent. Cleveland Clinic says erections should start improving about 3 to 6 months after surgery and that full hardness may take 2 years or longer; a 2009 meta-analysis of 9,965 operations found that 58% of men recovered erections overall, 77% of those under 60. While you wait, a treatment ladder of tablets, creams, injections, vacuum pumps and implants can give usable erections at almost any stage.
How long does erectile dysfunction last after a radical prostatectomy?
Erectile dysfunction after radical prostatectomy lasts at least several months for nearly every man, improves for up to 2 years, and is permanent for a minority. Cleveland Clinic states that "erections may not return for several months", that function "should start improving about three to six months after surgery", and that full hardness and sexual function "may take two years or longer". Macmillan Cancer Support tells patients that erections may slowly return but that this can take 1 to 2 years. Cancer Research UK says plainly that "almost all men have problems getting an erection after surgery" and that for some men the problem is permanent.
The timeline reflects the injury: Cancer Research UK explains that surgery damages the nerves and blood vessels next to the prostate that are needed for an erection, and stretched nerves recover slowly.
| Milestone | What the sources say |
|---|---|
| Weeks 0 to 6 | Catheter out, wound healing; Macmillan advises waiting 6 weeks before anal sex |
| 3 to 6 months | Erections should start improving (Cleveland Clinic) |
| 12 months | Most improvement has happened; 58% recovery across 22 studies (Tal 2009) |
| 18 to 24 months | Recovery still rising; studies with 18-month follow-up report 60% vs 56% (Tal 2009) |
| Beyond 2 years | Further recovery is uncommon; permanent ED for some (Cancer Research UK) |
Macmillan adds that recovery is less likely if hormone therapy or radiotherapy follows surgery.
How do age and nerve-sparing change the odds of recovery?
Younger men and men whose nerves were spared on both sides recover far more often. The 2009 meta-analysis by Tal, Mulhall and colleagues pooled 22 studies covering 9,965 radical prostatectomies (mean age 61). The recovery rate was 77% in men under 60 against 61% in men 60 and over, and 60% after bilateral nerve-sparing against 47% after unilateral.
| Factor | Erection recovery rate (Tal 2009) |
|---|---|
| All men | 58% (95% CI 56 to 60%) |
| Under 60 years | 77% |
| 60 years and over | 61% |
| Bilateral nerve-sparing | 60% |
| Unilateral nerve-sparing | 47% |
| Follow-up 18 months or more | 60% |
| Follow-up under 18 months | 56% |
"Recovery" in those studies often meant an erection firm enough for intercourse, sometimes with tablets. A stricter study by Nelson, Mulhall and colleagues (Journal of Sexual Medicine, 2013) asked how many of 180 men got back to their own pre-surgery erection score at 24 months. The answer was 43% with or without a PDE5 inhibitor tablet, and 22% without one. Among men who had good erections before surgery, only 16% were back to baseline without tablets; men under 60 managed 23% against 4% of men 60 and over.
Two cautions apply in India: the studies come from high-volume Western centres, and they used 22 different definitions of success. Ask your urologist which nerves were spared and what their own patients report.
What about erectile dysfunction after TURP?
After TURP for a benign enlarged prostate, erectile dysfunction is a possible but not expected side effect, and most men who have sexual problems recover within a year. The NHS lists "difficulty getting or keeping an erection" among the possible complications of TURP, alongside having no semen on ejaculation, which it says does not change how sex feels. The NHS does not give frequencies and says the surgeon will discuss the chance of each complication.
The US National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) says surgery for an enlarged prostate may temporarily affect the ability to have sex, and that "most men regain their ability to have sex within a year", depending on the type of surgery and how long symptoms lasted beforehand. The NIDDK adds that bladder control problems after these operations usually go away over several months.
The expected change after TURP is dry or reduced ejaculation, not loss of erection. The NHS says you may have no semen when you ejaculate, which affects fertility. Macmillan Cancer Support notes that a previous TURP is one of the factors that lowers the chance of erection recovery if a radical prostatectomy follows later.
In India, TURP is widely available in government district hospitals and medical colleges as well as private centres. If erections were normal before TURP and have not returned by 6 to 12 months, see a urologist: the NIDDK and NHS both treat persistent problems as something to assess, not something to accept.
What is the treatment ladder for erections after prostate surgery?
The treatment ladder runs from tablets, to creams or pellets, to injections, to vacuum pumps, and finally to a penile implant; each step works for some men the previous step failed.
| Step | How it works | Onset and duration (Cancer Research UK) |
|---|---|---|
| PDE5 inhibitor tablets (sildenafil, tadalafil, vardenafil, avanafil) | Increase blood flow; need sexual stimulation | Taken before sex; side effects include headache, flushing, indigestion |
| Alprostadil cream | Applied to the opening of the penis | Erection in 5 to 30 minutes, lasts 1 to 2 hours |
| Alprostadil urethral pellet | Placed in the urethral opening | Erection in about 10 minutes, lasts up to 60 minutes |
| Alprostadil injection | Injected into the side of the penis | Erection within 15 minutes, lasts up to an hour |
| Vacuum pump with ring | Draws blood in; ring holds it | Ring off within 30 minutes |
| Penile implant | Inflatable or malleable rods placed in a short operation | Permanent; considered when other treatments fail |
The NHS calls PDE5 inhibitors "the main treatments". The NIDDK says clinicians teach men to self-inject and that "most people with ED do not need surgery". Cancer Research UK says inflatable implants are the most common type.
In India, sildenafil and tadalafil are prescription medicines; injections, pumps and implants come through urology and andrology departments in larger cities. Ask the urologist which steps the hospital offers and what each costs.
When should each treatment start and how long should you try it?
Start treatment early, use tablets on demand, and move up a step when a fair trial fails rather than waiting for erections to return on their own. Cancer Research UK recommends starting penile rehabilitation "before or soon after" treatment, whether or not you are sexually active, with the aim of keeping blood flowing to the penis. Macmillan says rehabilitation may begin soon after prostatectomy because the operation "can cause ED problems quickly", but adds that "there is not enough evidence to show how effective it is yet".
For tablets, a 2018 Cochrane review of 8 randomised trials and 1,699 men found that scheduled daily PDE5 inhibitors "may not promote self-reported potency and erectile function any more than on demand use", with very low quality evidence.
If tablets fail, the next steps do not depend on nerves. Alprostadil cream, pellets and injections act directly on the erectile tissue, and a vacuum pump works mechanically. Cleveland Clinic lists PDE5 inhibitors, injection therapy and a pump as the options after radical prostatectomy and says intercourse and masturbation help maintain blood flow.
The NIDDK sets the safety limits: an erection lasting over 4 hours (priapism) after any tablet, injection or pellet needs care right away, and so does sudden loss of vision or hearing after a tablet. An implant is a last step, and Cancer Research UK says it is considered only when other treatments have not worked.
How do you cope with the emotional side of erectile dysfunction?
The emotional damage is real, common and treatable, and partners usually cope better than men expect. A 2017 mixed-methods study in BMC Urology (Albaugh and colleagues) interviewed 27 men treated for prostate cancer 1 to 5 years earlier, 92.6% of them by surgery, and 9 partners. Many men reported depression and anxiety, some reported suicidal thoughts, and many linked erectile dysfunction to feeling "less of a man". Yet "few partners reported being upset about their male partners' sexual dysfunction", and the authors found that "communication was at the heart of" the support men valued. Many couples kept intimacy through non-penetrative sex.
Macmillan Cancer Support says sexual difficulties can be "very difficult to cope with", with or without a partner, and that body image may change. It advises talking openly, bringing a partner to appointments, and asking the team for a referral to an ED clinic or sex therapist. Cancer Research UK says counselling can be arranged through a GP or specialist nurse and that healthy living, including stopping smoking and cutting alcohol, may improve erections and interest in sex.
The NHS says counselling and therapy help when emotional or mental health issues are involved, and the NIDDK lists counselling, with partners invited, as part of ED treatment. In India, psychosexual counselling is offered by psychiatrists and clinical psychologists in most medical college hospitals; a referral from the urologist is the usual route. If low mood lasts more than 2 weeks, or you have thoughts of harming yourself, tell a doctor the same day; in an emergency call 112.
When should you see a urologist about erectile dysfunction?
See a urologist before surgery to plan rehabilitation, at 3 months if nothing is prescribed, and at any point when a treatment fails or a side effect appears. The NHS advises seeing a doctor whenever "erection problems keep happening", because they can signal a treatable condition; Cancer Research UK says sexual health can be raised at any stage of cancer care, more than once.
Get help the same day if an erection lasts more than 4 hours after a tablet, injection or pellet, if you suddenly lose vision or hearing after a tablet, if the penis becomes very painful, bent or swollen, or if you have chest pain during sex. In India call 112 for an ambulance or go to the nearest emergency department.
Book a routine urologist visit when: no rehabilitation plan was given at discharge; tablets have not worked after several attempts at full dose with stimulation; you want to move to injections, a pump or an implant; erections have not begun to return by 12 months; or you have hormone therapy or radiotherapy planned, since Macmillan says these lower the chance of recovery.
For the mood changes, ask for a psychiatrist or psychologist referral; Macmillan and Cancer Research UK both treat counselling as part of ED care. In India, government medical college hospitals have urology and psychiatry outpatient departments, and andrology clinics in larger cities offer the full ladder.
