What can go wrong
Beyond ED and ejaculatory loss, treatments carry incontinence (surgery), bowel and urinary irritation (radiation), and the systemic effects of ADT. Penile shortening, climacturia (urine leakage at orgasm), and altered orgasm are also reported. Sexual outcomes should be weighed against oncologic benefit for each individual.
This is something to take to a clinician. The Atlas can tell you what is known about prostate cancer treatment & sexual function 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.
Every major prostate cancer treatment carries sexual consequences. Radical prostatectomy injures the cavernous nerves and removes the prostate and seminal vesicles, causing erectile dysfunction and permanent loss of ejaculation; recovery of erections depends heavily on nerve-sparing status and patient factors. Radiation causes a more gradual decline in erectile function over months to years. Androgen deprivation therapy collapses libido and erectile function as a class effect. Penile rehabilitation and nerve-preservation techniques improve - but do not guarantee - recovery.
Curing the cancer and preserving sexual function are different goals - and patients deserve honest numbers.
What people take it for
What it is taken for. Approval, where it exists, covers only some of these.
How it works
Prostatectomy damages the neurovascular bundles running alongside the prostate that carry the nerve signals for erection, and removes the structures responsible for ejaculate, producing dry orgasm. Radiation injures penile vasculature and nerves progressively via fibrosis and microvascular damage. ADT removes the androgen drive for libido and erectile tissue health. Outcomes vary enormously by surgeon experience, nerve-sparing extent, baseline function, age, and comorbidity.
Why the numbers vary so widely
Reported potency-recovery figures after prostatectomy range from roughly 40% to over 90%, which can mislead patients. The spread reflects differences in definition of 'recovery,' baseline function, nerve-sparing status (bilateral outperforms unilateral, which outperforms none), surgeon volume, and whether penile rehabilitation was used. Rehabilitation (early PDE5 inhibitors, vacuum devices, sometimes injections) has shown higher recovery in some series but evidence is mixed; orgasm without ejaculation is permanent after prostatectomy regardless.
Safety in detail
Prostate cancer treatment decisions involve significant, often permanent physiological effects and require evaluation and counseling by a qualified urologic oncology team. Sexual outcome expectations should be discussed before treatment.
What people get wrong
Often saidNerve-sparing surgery guarantees you keep erections
ActuallyNerve-sparing improves the odds substantially but does not guarantee recovery; outcomes depend on baseline function, age, surgeon, and rehabilitation.
Often saidYou can still ejaculate after prostatectomy
ActuallyRemoval of the prostate and seminal vesicles makes orgasm dry and ejaculation permanently absent.
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.
Set against the alternatives
Surgery removes the gland and ends ejaculation immediately but offers clear pathological staging; radiation preserves ejaculation longer but erectile decline accumulates over years and is often irreversible; ADT (alone or added) reliably suppresses libido and erections. Active surveillance avoids all of these in appropriate low-risk disease.
At a glance
- Prostatectomy
- ED + permanent loss of ejaculation
- Bilateral nerve-sparing recovery
- commonly ~60-75% potency in selected series
- Radiation
- gradual ED over months-years
- ADT
- libido + erectile collapse (class effect)

The studies that matter
Modern nerve-sparing robotic prostatectomy series2010s-2020s
Bilateral intrafascial nerve-sparing yielded high potency recovery in selected patients, far exceeding non-nerve-sparing
Penile rehabilitation comparisons2010s
Rehabilitation groups showed greater erectile recovery (e.g., ~60% vs ~38%) in some studies, though RCT evidence is mixed
Long-term post-prostatectomy ED data2000s-2020s
ED affects a large majority within 2-5 years absent nerve preservation and rehabilitation
