What Happens If You Don’t Have a Prostate?

Losing a prostate, whether through surgery for cancer or, very rarely, through a congenital condition, changes several bodily functions at once. The prostate sits at the crossroads of the urinary and reproductive systems, contributing roughly a third to nearly half of the fluid in each ejaculate and acting as a muscular valve that helps control both urine flow and the mechanics of orgasm. When it is gone, ejaculation stops entirely, urinary control takes a hit (sometimes temporarily, sometimes permanently), and erectile function often declines. The story is more nuanced than that summary, though, and recovery trajectories vary widely depending on the surgical technique, the individual’s anatomy, and what kind of support they receive afterward.

What the Prostate Actually Does Day to Day

The prostate is a walnut-sized gland wrapped around the urethra just below the bladder. Its primary job is producing a slightly alkaline fluid rich in enzymes and proteins that mixes with sperm during ejaculation. A study measuring the relative contributions of each reproductive gland found the prostate accounted for about 37 to 44 percent of the total ejaculate volume, with the seminal vesicles supplying most of the rest.1PubMed Central. A new method to estimate quantitatively seminal vesicle and prostate gland contributions to ejaculate Beyond reproduction, the prostate’s muscular tissue contracts during orgasm, contributing to the physical sensation of climax, and its position around the urethra means it plays a structural role in urinary continence. Removing it means all of these roles must be absorbed by surrounding tissues or simply go unfilled.

Ejaculation Stops, but Orgasm Does Not Necessarily Disappear

After a radical prostatectomy, there is no ejaculate. The prostate and seminal vesicles, which together produced the vast majority of semen fluid, are both removed. Sperm are still produced in the testes, but they have no route to exit the body during sex. This is one of the changes that surprises people the most: the sensation of orgasm can persist, but the physical release of fluid does not.

That said, the character of orgasm often changes. Without the rhythmic contractions of the prostate and seminal vesicles, the sensation can feel muted, shorter, or qualitatively different. Research has found that the absence of those contractions, along with the loss of ejaculation itself, can compromise how satisfying orgasm feels, even when libido and erections are preserved.2PubMed. Orgasm after radical prostatectomy Some men describe it as an orgasm without the “punctuation mark” at the end. Others adapt over months and report the sensation gradually becoming more recognizable again. The experience is highly individual.

Climacturia and the Urine-at-Orgasm Problem

One of the more distressing surprises for people after prostate removal is climacturia, the involuntary loss of urine during orgasm. A study of men who had undergone radical prostatectomy found that about 45 percent reported climacturia, though the majority said it happened rarely or only occasionally.3PubMed. Climacturia following radical prostatectomy: prevalence and risk factors Most described losing only a few drops, while a smaller group reported more than an ounce. About half said the symptom did not bother them much, while the other half found it significantly distressing. A larger study of prostate cancer survivors found orgasm-associated urinary incontinence in roughly a fifth of the population, the majority of whom were otherwise continent during everyday activities.4The Journal of Sexual Medicine. Orgasm‐Associated Urinary Incontinence and Sexual Life After Radical Prostatectomy

The mechanism is straightforward: the prostate once served as part of the seal between the bladder and the urethra. With it gone, the muscular control needed to prevent urine from escaping during the intense pelvic-floor contractions of orgasm is weaker. Emptying the bladder before sex and using a constriction ring at the base of the penis are two commonly recommended workarounds, though neither eliminates the problem for everyone.

Urinary Continence and How It Recovers

Beyond the specific situation of orgasm, everyday urinary control is one of the biggest quality-of-life concerns after prostate removal. The surgery disrupts the internal urethral sphincter, which the prostate helped support, leaving the external sphincter to do a job it was never solely designed for. Most men experience some degree of leakage in the weeks and months after surgery. How quickly and completely continence returns depends on surgical technique, age, body weight, and how much pelvic-floor training the person does.

Pelvic floor muscle training is the first-line treatment. A meta-analysis pooling data from multiple trials found that men who did structured pelvic-floor exercises had significantly better continence at one, three, six, and twelve months after surgery compared to those who did not.5PubMed Central. The therapeutic effect of pelvic floor muscle training on stress urinary incontinence following prostatectomy: a systematic review and meta-analysis A randomized controlled trial found that starting exercises before surgery (prehabilitation) helped men return to continence faster and experience less leakage overall.6PubMed Central. Pelvic floor muscle training in radical prostatectomy: a randomized controlled trial of the impacts on pelvic floor muscle function and urinary incontinence These exercises are essentially what people know as Kegels, targeted at strengthening the muscles that squeeze the urethra shut.

For men whose incontinence persists beyond the first year despite conservative treatment, surgical options exist. Both male slings and artificial urinary sphincters have been shown to reduce pad use by about three pads per day and achieve cure rates around 60 percent.7PLoS ONE. Surgical treatment for urinary incontinence after prostatectomy: A meta-analysis and systematic review Slings are less invasive and do not require the manual dexterity needed to operate a mechanical sphincter, making them attractive for some patients.8PubMed Central. Male Slings for Post-prostatectomy Incontinence The artificial urinary sphincter remains the most established option for severe cases, though it requires more complex surgery and potential revisions down the line.9PubMed Central.

Erectile Function and the Nerve-Sparing Question

The nerves responsible for erections run along both sides of the prostate in delicate bundles. Even when surgeons use nerve-sparing techniques, trying to peel the prostate away without damaging those bundles, some degree of erectile dysfunction is common afterward. Nerve-sparing approaches have reduced the incidence, but they have not eliminated it.10Siberian Journal of Clinical and Experimental Medicine. Current and future strategies for managing erectile dysfunction following nerve-sparing robot-assisted radical prostatectomy (literature review) Surgical refinements continue: research comparing cold (non-thermal) dissection to traditional thermal instruments during nerve-sparing robotic surgery found that avoiding heat damage led to consistently better erectile function recovery.11PubMed Central. Comparative Analysis of Cold Versus Thermal Dissection in Nerve-Sparing Robot-Assisted Radical Prostatectomy

One persistent question is whether medications like sildenafil (Viagra) or tadalafil (Cialis) can rehabilitate erections if taken regularly after surgery. Despite early optimism, large randomized trials have not shown that daily use of these drugs leads to better long-term unassisted erectile function compared to taking nothing.12PubMed Central. PDE-5 inhibitors should be used post radical prostatectomy as erection function rehabilitation? | Opinion: No. They can help produce erections when taken on demand for sex, but the idea that consistent use “trains” the tissue back to health has not held up under rigorous testing. Many urologists still prescribe them in the hope of maintaining penile blood flow, but the evidence for permanent recovery from that approach is thin.

Temporary Changes in Penile Length

A concern that rarely gets discussed before surgery is a measurable but usually temporary shortening of the penis. One study found that stretched penile length dropped by about half a centimeter on average one month after robotic prostatectomy.13PubMed. Changes in penile length after robot-assisted laparoscopic radical prostatectomy A longer-term prospective study tracked men for five years and found that average length decreased by about a centimeter at three months, and this difference persisted through the two-year mark. By four and five years, however, the difference from the pre-surgery baseline was no longer statistically significant, and erectile function was a predictor of how quickly length returned.14PubMed. The natural history of penile length after radical prostatectomy: a long-term prospective study The likely explanation involves a combination of nerve injury, reduced blood flow, and disuse atrophy in the erectile tissue during the period when erections are impaired. As nerve function and blood flow recover, so does length for most men.

What Happens to Hormones After Removal

The prostate itself does not produce testosterone; the testes do. So removing the prostate does not directly strip away the body’s main source of male hormones. That said, the hormonal picture is not entirely static. One study found that mean serum testosterone dropped from about 425 ng/dL before surgery to about 372 ng/dL afterward, a decline of roughly 12 percent.15International Journal of Impotence Research. Pre- and post-radical prostatectomy testosterone levels in prostate cancer patients Men with more aggressive tumors (higher Gleason grades) tended to have bigger drops. The reasons are not fully understood but likely involve the stress of major surgery, changes in the hypothalamic-pituitary feedback loop, and in some cases the use of temporary hormone therapy around the time of surgery.

Interestingly, an older study found the opposite direction for some hormones: testosterone, free testosterone, estradiol, and two pituitary hormones (LH and FSH) all rose significantly after prostatectomy, while dihydrotestosterone (DHT) fell.16PubMed. Influence of radical prostatectomy on serum hormone levels The drop in DHT makes sense because the prostate is one of the major sites where testosterone is converted into DHT. With the gland gone, less conversion occurs. The rise in testosterone in that study may reflect the removal of a tissue that was consuming testosterone locally. These two studies examined different populations and timeframes, which likely explains the divergent findings, but the key point for someone living without a prostate is that testosterone production continues, and dramatic hormonal collapse is not typical.

PSA Monitoring Without a Prostate

Prostate-specific antigen (PSA) is produced almost exclusively by prostate tissue. After a complete prostatectomy, PSA should drop to undetectable levels. If it starts climbing again, that is a strong signal that prostate cancer cells have survived somewhere in the body, a situation called biochemical recurrence. Modern ultrasensitive PSA tests can detect extremely low levels, which is both a benefit and a source of anxiety. Very faint detectable readings may not always indicate true recurrence because the test becomes less reliable at extremely low thresholds, and the false-positive rate rises as the detection limit falls.17PubMed Central. Prognostic Implications of an Undetectable Ultrasensitive Prostate-Specific Antigen Level after Radical Prostatectomy Still, regular PSA checks remain the cornerstone of post-surgery cancer surveillance.

Fertility After Prostate Removal

Without a prostate or seminal vesicles, natural conception is off the table. No ejaculate means no way for sperm to reach a partner during intercourse, even though the testes keep producing sperm. For younger men or those who want biological children in the future, sperm cryopreservation (banking sperm before surgery) is the simplest option. After surgery, it is still possible to retrieve sperm directly from the testes through a procedure called testicular sperm extraction, which can then be used with assisted reproductive technologies like IVF.18PubMed Central. Prostate Cancer Treatments and Their Effects on Male Fertility: Mechanisms and Mitigation Strategies

Awareness of these options is surprisingly low. A survey of men undergoing radical prostatectomy found that only 2 percent knew that testicular sperm extraction was a possibility after surgery.19PubMed. Knowledge and Attitudes Towards Fertility Preservation in Patients Undergoing Radical Prostatectomy Prostate cancer is increasingly being diagnosed in younger men, and fertility counseling before treatment remains inconsistent. If future parenthood matters to you, the conversation about sperm banking needs to happen before the surgery, not after.

Bladder Neck Contracture and Strictures

When the prostate is removed, the surgeon must reconnect the bladder directly to the remaining urethra. That junction can sometimes scar down and narrow over time, a complication known as bladder neck contracture. It can cause a weak urine stream, difficulty emptying the bladder, or urinary retention. The rates of this complication appear similar across different prostate cancer treatments, including surgery, radiation, and newer ablation techniques.20PubMed. Management of Urethral Stricture and Bladder Neck Contracture Following Primary and Salvage Treatment of Prostate Cancer

Most cases respond to relatively simple endoscopic treatments such as dilation or incision.21PubMed Central. Management of bladder neck stenosis and urethral stricture and stenosis following treatment for prostate cancer For the small number of people who develop recurrent or stubborn strictures, more complex reconstruction may be needed, which itself carries a risk of worsening urinary incontinence. This is a complication worth knowing about because the symptoms, a gradually weakening stream or increasing difficulty urinating, can develop months or even years after surgery and are sometimes mistaken for other problems.

How Prostate Removal Compares to Radiation

Not everyone with prostate cancer has their prostate removed. Radiation therapy treats the gland in place, and the side-effect profiles of the two approaches are notably different. A large register-based study comparing outcomes one year after treatment found that urinary incontinence was reported by about 13 percent of men after robotic prostatectomy versus 6 percent after radiation. But radiation carried its own burdens: irritative urinary symptoms were roughly twice as common, obstructive symptoms about three times as common, and bowel urgency affected about a third of radiation patients compared to 14 percent after surgery. Erectile dysfunction rates were similar between the two groups, around three-quarters of men in both arms.22European Urology Oncology. Patient-reported Side Effects 1 Year After Radical Prostatectomy or Radiotherapy for Prostate Cancer: A Register-based Nationwide Study

Newer focal treatments such as prostate gland ablation aim to destroy just the cancerous area while preserving surrounding tissue. A large retrospective study found that ablation was associated with lower early rates of erectile dysfunction and urinary incontinence compared to full prostate removal, though urinary retention was about three times more common with ablation.23PubMed. Real-world functional and oncologic outcomes of prostate gland ablation vs. standard of care therapies for localized prostate: A retrospective cohort study using the TriNetX database The trade-offs are real, and the “best” treatment depends on the cancer’s characteristics, the person’s priorities, and their baseline function.

The Emotional and Relationship Dimension

Living without a prostate is not just a physical adjustment. Studies show that anxiety and depression scores actually improve substantially in the first month after surgery for many men, likely because the immediate threat of untreated cancer has been addressed.24PubMed Central. Effect of radical prostatectomy on anxiety, depression, and quality of life in patients diagnosed with prostate cancer Overall quality of life in most domains outside urinary and sexual function tends to return to baseline within about five months. Urinary function, however, takes longer, with only about two-thirds of men reaching their pre-surgery baseline by the end of the first year.25PubMed. Quality of life following radical prostatectomy

Fear of cancer recurrence is a persistent psychological burden, and its impact on quality of life depends partly on how satisfied the person feels with their treatment. Research has found that men who reported higher treatment satisfaction were better buffered against the mental-health toll of worrying about recurrence.26PubMed. Fear of recurrence, treatment satisfaction, and quality of life after radical prostatectomy for prostate cancer This sounds circular, but the practical implication is that clear pre-surgical communication about what to expect, including the less-discussed side effects like climacturia and altered orgasm, may help set realistic expectations that lead to greater satisfaction down the line.

Partners are often an overlooked part of the equation. Studies on couples recovering sexual intimacy after prostatectomy have found that partners frequently hold back their own feelings and concerns, which damages both their well-being and the couple’s intimacy.27PubMed Central. Predictors of Patient and Partner Satisfaction Following Radical Prostatectomy Couples who adapted most successfully tended to be those who pursued sexual activity intentionally and openly, where patients accepted the use of erectile aids and partners expressed their own interest in maintaining intimacy. The endpoint these couples described was not a return to pre-surgical erectile function but rather reaching a point where sex felt unselfconscious again.28PubMed Central. What couples say about their recovery of sexual intimacy after prostatectomy: toward the development of a conceptual model of couples’ sexual recovery after surgery for prostate cancer

Born Without a Prostate

Almost every discussion of “not having a prostate” assumes surgical removal, but a tiny number of people are born without one. Congenital prostate agenesis is exceptionally rare and is usually discovered incidentally, sometimes during a procedure for an unrelated urological complaint. A recent case report describes a generally healthy man who presented with flank pain and reduced semen volume; the absence of his prostate was discovered during an endoscopic procedure.29PubMed Central. Congenital agenesis of the prostate accompanied by bilateral ectopic ureters and retrograde ejaculation: A case report

The condition tends to show up alongside other urogenital anomalies like ectopic ureters, absent vas deferens, absent seminal vesicles, or penile abnormalities. Embryologically, the prostate develops from the urogenital sinus under the influence of androgens and the enzyme 5-alpha reductase. Deficiencies in that enzyme, or in certain developmental genes like the Hox gene family, can prevent the gland from forming at all. Because the condition is so rare and usually accompanied by other structural differences, people born without a prostate face a different constellation of challenges than those who lose one to surgery. Reduced semen volume and retrograde ejaculation (where semen flows backward into the bladder) are typical findings.

Transgender Women and the Prostate

Transgender women who undergo gender-affirming vaginoplasty typically retain their prostate, which means prostate cancer screening remains relevant throughout their lives. On rare occasions, prostate cancer does develop in transgender women, and treatment can be complicated by the altered anatomy. A case report of prostatectomy after vaginoplasty emphasized the need for lifelong follow-up with clinicians equipped to perform neovaginal exams when indicated.30Urology Case Reports. Prostateectomy after gender-affirming vaginoplasty for a transgender woman with prostate cancer Long-term estrogen therapy suppresses PSA levels, which can mask early cancer signals. This is a population for whom the question “what if you don’t have a prostate?” takes on a different slant: the prostate is present but often forgotten in clinical care, creating its own set of risks.
