Most men facing prostatectomy focus on one thing: getting the cancer out. Sexual function is an afterthought — something to deal with later. Then surgery happens, and suddenly it is all they can think about.
A 2025 survey published in Clinical Oncology found that more than 98% of prostate cancer patients reported new-onset sexual problems after treatment, with erectile dysfunction affecting 91% of those who had surgery. [1] And yet the majority received little to no guidance about what to expect or what to do about it.
This article is the conversation your urologist probably did not have time to have with you.

What Actually Happens to Sexual Function After Surgery
Prostatectomy affects sexual function in several ways simultaneously. Understanding all of them — not just erectile dysfunction — is the first step toward honest recovery expectations.
Erectile Dysfunction (ED)
The most discussed side effect. Nearly all men experience some degree of ED immediately after surgery. Recovery varies widely based on age, pre-operative function, surgical technique, and whether nerve-sparing was performed.
Dry Orgasm (Anejaculation)
The prostate and seminal vesicles are removed during surgery, which means ejaculation as you knew it no longer occurs. Orgasm is still possible — and for many men remains pleasurable — but it will be dry. This is permanent and expected. Many men are not adequately warned about this before surgery.
Penile Shortening
A 2024 review identified penile shortening as a common and distressing consequence of prostatectomy, affecting up to 70% of men. [1] This occurs due to smooth muscle changes in the erectile tissue when erections are absent for extended periods — which is exactly why early penile rehabilitation matters.
Loss of Sexual Desire and Confidence
A 2025 qualitative study found that many men develop what researchers described as a state of "no demand for sexual life, no expression" — suppressing sexual needs entirely rather than confronting the changes surgery has caused. [3] This psychological withdrawal is common, understandable, and addressable.
Why ED Occurs — The Nerve Injury Explained
The erectile nerves — the cavernous nerves — run directly alongside the prostate. Even in nerve-sparing surgery, these nerves experience trauma: stretching, compression, heat, and temporary loss of blood supply. The nerves are not cut, but they are injured.
Recovery depends on nerve regeneration, which is slow. In the meantime, the erectile tissue of the penis — the corpus cavernosum — is at risk of permanent structural change if it receives no oxygenation. Erections are how the penis oxygenates itself. Without erections, smooth muscle fibers can be replaced by fibrous tissue, making recovery harder over time.
Key InsightThis is why early intervention matters so much. The window for protecting penile tissue is in the first 6–12 months after surgery. Waiting to "see what happens" can reduce the chances of meaningful recovery.
Nerve-Sparing vs. Non-Nerve-Sparing Surgery
Research consistently shows that bilateral nerve-sparing radical prostatectomy offers significantly better erectile function recovery outcomes. A 2024 systematic review found that robotic-assisted radical prostatectomy showed higher rates of erectile function recovery at all time points from 1 to 18 months compared to open surgical approaches. [4] However, nerve-sparing is not always oncologically appropriate — your surgeon's decision must prioritize cancer control first.
Realistic Recovery Timeline
One of the most damaging things men experience is unrealistic expectations. They are told erections "may return" without being told that for many men, full recovery takes 2 years or more — and for some, it never returns to baseline without help.
A 2025 study found that sexual function recovery rates fluctuate between 0 and 40% at 12 months post-surgery, and only 3 to 44% at 24 months follow-up. [3] The wide range reflects individual variation — but it also reflects the difference between men who pursue active rehabilitation and those who do not.
General Timeline0–3 months: Focus on incontinence recovery first. Erections unlikely but spontaneous activity is encouraging. 3–6 months: Early penile rehabilitation interventions most impactful. 6–12 months: Progressive improvement with consistent rehabilitation. 12–24 months: Continued gradual recovery. After 24 months: Plateau for most men without intervention, though improvement is still possible.
Factors That Affect Recovery
- Age — younger men generally recover faster and more completely
- Pre-operative erectile function — better baseline = better recovery
- Bilateral vs. unilateral nerve sparing — bilateral is significantly better
- Diabetes and cardiovascular health — a 2024 Memorial Sloan Kettering study found diabetes substantially worsens long-term ED recovery after prostatectomy [5]
- Smoking — associated with significantly worse urinary and sexual function recovery [6]
- Early rehabilitation — the single most modifiable factor
Penile Rehabilitation — What the Research Shows
Penile rehabilitation refers to using medical interventions proactively — not waiting until you want to have sex, but starting treatment early to protect tissue and support nerve recovery.
A 2024 review from Indiana University defined penile rehabilitation as "the use of any drug or device at or after radical prostatectomy to maximize recovery of erectile function." [2] Multiple strategies have evidence behind them.
PDE5 Inhibitors (Sildenafil, Tadalafil)
Medications like Viagra (sildenafil) and Cialis (tadalafil) are often prescribed early after surgery — not for sexual activity, but as a rehabilitation tool. The REACTT trial demonstrated that daily tadalafil was significantly more effective than placebo for drug-assisted erectile function after bilateral nerve-sparing prostatectomy. Daily low-dose tadalafil also showed reduced penile length loss versus placebo at 9 months. [2] Discuss early prescription with your urologist.
Vacuum Erection Devices (VED)
A vacuum erection device draws blood into the penis mechanically. Used early and regularly — even without sexual intent — it helps maintain penile tissue oxygenation and may reduce fibrotic changes. Most rehabilitation protocols recommend starting VED use within 4–6 weeks of catheter removal.
Intracavernosal Injections
For men who do not respond to oral medications, penile injections (typically alprostadil) can produce erections reliable enough for sexual activity while also supporting tissue rehabilitation. Though the idea sounds daunting, most men who try them find them manageable and effective.
The Multidisciplinary Approach
The Indiana University review emphasized that optimal outcomes require a multidisciplinary approach — combining patient education, psychological counseling, pelvic floor physical therapy, and the appropriate medical interventions tailored to the individual. [2] No single intervention alone produces the best results.
The Pelvic Floor Connection Most Men Miss
Here is what most men — and many urologists — do not fully appreciate: the pelvic floor muscles play a direct role in erectile function and orgasm quality.
The bulbocavernosus and ischiocavernosus muscles, which are pelvic floor muscles, contract rhythmically during orgasm and help maintain erection by compressing the veins that allow blood to leave the penis. When these muscles are weak, uncoordinated, or inhibited — which often happens after prostatectomy surgery — erectile rigidity and orgasm intensity are reduced even when nerve function is intact.
This means pelvic floor rehabilitation is not just about bladder control. It is directly relevant to sexual function recovery.
Clinical PearlMen who achieve urinary continence faster after prostatectomy — through structured pelvic floor training — also tend to report better sexual function outcomes. The two systems are anatomically and functionally intertwined.
Proper pelvic floor training after prostatectomy is not simply doing Kegel exercises. It requires understanding how to coordinate contraction and relaxation, how to avoid the common mistake of bearing down instead of lifting, and how to progress exercises appropriately through your recovery phases. This is exactly what our post-surgery classes address.
Intimacy Beyond Intercourse
One of the most important — and least discussed — aspects of sexual recovery after prostatectomy is redefining what intimacy means during the recovery period.
Research consistently shows that men who adopt a rigid definition of sexual success — penetrative intercourse with a firm erection — suffer more psychologically and report worse relationship satisfaction than men who expand their definition of intimacy. [3]
A 2025 study published in Frontiers in Oncology found that prostate cancer and its treatment function as a "family disease" — profoundly affecting the couple's relationship, communication, and shared identity, not just the patient's individual experience. [3]
What this means practically:
- Orgasm is still possible after prostatectomy — even without an erection — through manual or oral stimulation
- Dry orgasms, though different, can still be pleasurable
- Physical closeness, touch, and emotional intimacy have independent value and should not be abandoned while waiting for erectile function to return
- Avoiding all sexual contact "until things work again" often extends the psychological impact and can damage relationships
Your Partner's Experience Matters Too
Men going through prostatectomy recovery are not the only ones affected. Partners experience their own anxiety, grief, and uncertainty — and they are frequently left out of the medical conversation entirely.
A 2025 study on non-penetrative sexuality found that partners of prostatectomy patients experience significant changes in their own sexual satisfaction and need their own support and information. [7] Partners often suppress their own needs to avoid pressuring the man during recovery — which can create distance and misunderstanding.
If you have a partner, consider:
- Talking openly about what you are both experiencing — silence typically makes things worse
- Attending a pelvic health education class together when appropriate
- Seeking couples counseling with a therapist who specializes in sexual health if needed
- Reassuring each other that this recovery phase is temporary and that intimacy can evolve
What Actually Helps — Practical Steps
Based on the current evidence, here is what gives men the best chance of meaningful sexual function recovery after prostatectomy:
1. Start Pelvic Floor Training Before Surgery
Men who begin pelvic floor exercises before surgery consistently show faster recovery of both continence and sexual function post-operatively. Our Pre-Surgery Preparation Class covers pelvic floor anatomy, correct technique, and what to expect — giving you the foundation to protect your recovery from day one.
2. Ask Your Urologist About Early Penile Rehabilitation
Within 4–6 weeks of catheter removal, discuss PDE5 inhibitors and vacuum erection device use with your urologist. Do not wait until you feel ready for sexual activity — the rehabilitation window is early.
3. Continue Structured Pelvic Floor Training After Surgery
Pelvic floor PT is not just for continence. The muscle coordination, blood flow, and nerve signaling that pelvic floor training supports are all relevant to erectile and orgasmic function. Our post-surgery recovery classes walk you through each phase of recovery from Month 1 through Month 10.
4. Address the Psychological Component
Suppressing sexual needs entirely, as many men do, is associated with poorer long-term outcomes. A brief course of sex-positive counseling — even 3–5 sessions — can significantly change a man's relationship with his own recovery.
5. Modify Lifestyle Risk Factors
Smoking, poor cardiovascular health, and uncontrolled diabetes are each independently associated with worse erectile function recovery after prostatectomy. [5,6] The best thing you can do for your sexual recovery is the same as what is good for your overall health.
6. Give It Time — But Stay Active
Recovery after prostatectomy is a marathon, not a sprint. Two years is a realistic timeline for maximum natural recovery. But passive waiting produces worse outcomes than active rehabilitation. Stay engaged with your recovery.
