Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is persistent or recurrent pelvic, perineal, genital or prostate-region pain in which an ongoing bacterial infection does not explain the symptoms. Pain is the central feature, but men can also experience urinary frequency or urgency, difficulty voiding, painful ejaculation, sexual problems, pelvic-floor muscle tenderness and symptom flares. CP/CPPS is therefore different from chronic bacterial prostatitis even though the two conditions can produce similar symptoms.
01. What Is CP/CPPS and What Symptoms Does It Cause?
What does CP/CPPS mean?
CP/CPPS stands for chronic prostatitis/chronic pelvic pain syndrome.
It is the NIH category III prostatitis syndrome.
Unlike chronic bacterial prostatitis, CP/CPPS does not have a demonstrated bacterial infection that explains the chronic symptom pattern.
The European Association of Urology increasingly uses the term primary prostate pain syndrome for persistent or recurrent pain perceived in the prostate region when there is no proven infection or another obvious local disease explaining it.
The terminology differs slightly between guideline systems, but the central clinical idea is similar: persistent prostate-region or pelvic pain can exist without ongoing bacterial infection.
How long do symptoms need to last?
Current EAU chronic-pelvic-pain guidance defines pain syndromes clinically from persistent or recurrent pelvic pain with other specific disease processes excluded for a minimum of approximately three months.
The time criterion helps distinguish a chronic pain syndrome from a short-lived acute urinary or prostate infection.
Duration alone, however, is not enough.
A man who has repeated positive urine cultures over three months may still have bacterial disease rather than CP/CPPS.
Where can CP/CPPS pain occur?
The pain is not restricted to one anatomical point.
Common locations include:
- the perineum between the scrotum and anus;
- deep pelvic or prostate-region pain;
- the penis;
- the testicles or scrotal region;
- the suprapubic lower abdomen;
- the rectal region;
- the groin;
- and sometimes the lower back or other body regions.
A multinational analysis of 1,563 men with CP/CPPS found perineal discomfort to be the most frequently reported pain location, followed by testicular, pubic-area and penile pain. Pain during ejaculation was also common.
The broader symptom pattern is covered in Prostatitis Symptoms.
Can CP/CPPS cause urinary symptoms?
Yes.
Men can experience:
- urinary frequency;
- urgency;
- hesitancy;
- weak or interrupted flow;
- discomfort associated with urination;
- or a sensation of incomplete emptying.
These symptoms are important because treatment may need to target the urinary component separately from the pain component.
Urinary symptoms do not prove that the prostate is enlarged or infected.
Can CP/CPPS cause painful ejaculation or sexual problems?
Yes.
Pain during or after ejaculation is a recognized feature of CP/CPPS.
Men may also report:
- avoiding sexual activity because they anticipate a flare;
- erectile difficulties;
- reduced sexual satisfaction;
- pelvic pain after orgasm;
- or anxiety about whether sexual activity will worsen symptoms.
Sexual symptoms should be evaluated directly rather than dismissed as secondary or unrelated.
Can CP/CPPS symptoms flare and then improve?
Yes.
Fluctuation is common.
A patient may have relatively quiet periods followed by several days or weeks of increased:
- perineal or penile pain;
- urinary urgency;
- pain after ejaculation;
- pelvic-floor tightness;
- or discomfort associated with sitting, physical activity or another individual trigger.
A flare does not automatically represent a new infection.
If a flare is accompanied by fever, chills, systemic illness or a positive urine culture, the interpretation changes and bacterial infection must be considered.
02. What Causes CP/CPPS if It Is Not a Bacterial Infection?
Is there one known cause of CP/CPPS?
No.
Current EAU guidance states that no single explanation has been established for primary prostate pain syndrome.
Possible initiating or maintaining factors include:
- a previous infectious or inflammatory event;
- pelvic-floor muscle dysfunction;
- myofascial pain;
- peripheral nerve sensitization;
- central nervous-system pain amplification;
- immune or inflammatory mechanisms;
- anatomical or urinary factors;
- and individual behavioral or psychological responses to persistent pain.
More than one mechanism can be active in the same person.
For the broader comparison of infectious and noninfectious mechanisms, see What Causes Prostatitis?.
Can an old infection trigger pain that continues after the infection is gone?
Possibly.
An infection or inflammatory event may provide the initial peripheral trigger in some men.
After the original trigger resolves, persistent changes in muscle tone, nerve sensitivity or central pain processing may help maintain symptoms.
This explains an important clinical pattern:
a previous infection can be part of the history without an ongoing infection being the current cause of the pain.
What is pelvic-floor myalgia?
Pelvic-floor myalgia refers to pain arising from tender, overactive or poorly relaxing pelvic-floor muscles.
A trained examiner may identify:
- increased muscle tone;
- trigger points;
- tender levator ani or other pelvic muscles;
- difficulty relaxing after voluntary contraction;
- or reproduction of the patient’s familiar pain during palpation.
Current EAU guidance specifically recommends looking for myofascial trigger points in chronic pelvic-pain assessment.
Pelvic-floor overactivity is also considered one input capable of driving ongoing nervous-system sensitization.
What is peripheral sensitization?
Peripheral sensitization means that local nerves become more responsive after repeated or prolonged stimulation.
Signals from muscles, prostate-region tissues, bladder structures or other pelvic organs can then produce disproportionate pain or discomfort.
What is central sensitization?
Central sensitization describes increased amplification of pain within the spinal cord and brain.
Once this develops, the relationship between visible tissue damage and the amount of pain becomes less direct.
A person may experience:
- pain from normally mild stimuli;
- pain spreading beyond the original location;
- greater sensitivity during symptom flares;
- or persistent pain after the original tissue trigger has healed.
Current EAU guidance recognizes neuroplastic and neuropathic mechanisms in chronic prostate-region pain.
Does stress cause CP/CPPS?
Stress should not be presented as a simple cause of CP/CPPS.
However, chronic pain and stress can influence one another.
Pain may worsen sleep, anxiety and activity levels, while increased stress can increase muscle guarding, autonomic arousal and pain sensitivity in some individuals.
Current EAU guidance specifically states that there is no evidence that psychological distress makes pelvic pain unreal or that multiple symptoms imply that the pain is fabricated.
Is inflammation always present?
No.
The traditional NIH category III system divided CP/CPPS into:
- IIIA: inflammatory CP/CPPS, where leukocytes are identified in selected prostate-associated samples;
- IIIB: non-inflammatory CP/CPPS, where those inflammatory findings are absent.
Both can produce substantial symptoms.
This is another reason the term “chronic prostatitis” can be misleading when used without defining the actual syndrome.
Does sitting or ejaculation cause CP/CPPS?
They are better understood as potential symptom triggers in some individuals rather than established universal causes.
A person may report greater pain after:
- prolonged sitting;
- sexual activity;
- ejaculation;
- high-intensity exercise;
- certain bowel movements;
- or another personal trigger.
Another patient may experience none of these associations.
A pain diary can help identify reproducible patterns without assuming that every fluctuation represents disease progression.
03. How Is CP/CPPS Diagnosed and Measured?
Is there a single test that proves CP/CPPS?
No.
Current EAU guidance states that there is no single specific diagnostic test for chronic primary pelvic-pain syndromes.
The clinical process has two goals:
- characterize the pain and associated urinary, sexual, bowel, muscular and neurological symptoms;
- identify or exclude a specific disease that would better explain the symptoms.
Evaluation is therefore individualized.
What conditions need to be considered before calling it CP/CPPS?
Depending on the presentation, clinicians may need to assess for:
- bacterial prostatitis or urinary tract infection;
- urethritis or sexually transmitted infection;
- urinary stones;
- urinary retention or significant obstruction;
- bladder pain syndrome;
- testicular or epididymal disease;
- pelvic-floor muscle dysfunction;
- neurological or spinal disease;
- anorectal disorders;
- and other urological disease when clinically indicated.
That is why persistent pelvic pain is not diagnosed from pain location alone.
What does the physical examination look for?
The examination is broader than simply checking whether the prostate is tender.
EAU guidance recommends assessment of:
- abdominal and pelvic tenderness;
- external genital structures;
- prostate abnormalities;
- pelvic-floor muscle tenderness;
- trigger points;
- and the ability of the pelvic floor to contract and relax.
A musculoskeletal and neurological examination may also be useful when the symptom distribution suggests a wider pain mechanism.
Can prostate localization cultures still be used?
They can be used when the main clinical uncertainty is whether bacterial prostatitis is present.
However, in suspected primary prostate pain syndrome, EAU evidence notes that positive prostate-localization cultures occur in only a small minority and at a frequency similar to that seen in asymptomatic men.
This means culture can help separate infection from noninfectious pain, but a sophisticated culture procedure does not “prove” CP/CPPS when it is negative.
What is the NIH Chronic Prostatitis Symptom Index?
The NIH Chronic Prostatitis Symptom Index (NIH-CPSI) is a validated questionnaire used to measure symptom severity and quality-of-life impact in chronic prostatitis/CPPS.
The standard scoring system has three domains:
- Pain: 0–21 points;
- Urinary symptoms: 0–10 points;
- Quality-of-life impact: 0–12 points.
The total score ranges from 0 to 43, with higher values representing a greater symptom burden.
The questionnaire is particularly useful for tracking change over time because pain location alone does not reliably represent overall disease severity.
Why is a pain diary useful?
A pain diary can reveal relationships that are difficult to recall accurately during a short clinic visit.
Useful variables can include:
- daily pain intensity;
- pain location;
- urination;
- ejaculation or sexual activity;
- bowel activity;
- sitting time;
- exercise;
- sleep;
- medication use;
- and major symptom flares.
EAU guidance specifically recognizes pain diaries as useful tools for monitoring chronic pelvic pain in the patient’s normal environment.
04. How Is CP/CPPS Managed?
Is there one best treatment?
No.
CP/CPPS is heterogeneous, so treatment works best when it targets the symptom pattern and the mechanisms identified in the individual patient.
The 2025 AUA guideline emphasizes a multimodal and sometimes multidisciplinary approach.
Current EAU guidance similarly recommends personalized management rather than expecting one intervention to treat every patient.
What role does patient education have?
Education is part of treatment.
Understanding that chronic pain can exist without ongoing tissue infection can reduce the cycle of repeatedly searching for a hidden bacterial cause after appropriate infection testing has remained negative.
A useful treatment discussion explains:
- what has been ruled out;
- which symptom domains appear most important;
- what improvement realistically means;
- which treatments are being tested;
- and how response will be measured.
Can pelvic-floor physical therapy help?
Yes, when pelvic-floor myalgia, overactivity or trigger points are present.
Treatment can include:
- manual myofascial techniques;
- learning pelvic-floor relaxation;
- breathing and down-training;
- stretching shortened muscles;
- improving pelvic movement and coordination;
- and biofeedback in selected cases.
This is different from simply performing repeated strengthening contractions.
A painful overactive pelvic floor may need to learn to relax before strengthening is considered.
Current EAU guidance supports myofascial treatment and recognizes pelvic-floor relaxation as an important strategy for interrupting a pain–spasm–pain cycle.
Are alpha-blockers used?
They can be useful when CP/CPPS is accompanied by bothersome voiding symptoms.
The 2025 AUA guideline recommends offering an alpha-blocker to patients with CP/CPPS who have voiding symptoms.
The purpose is to address the urinary component—not to imply that alpha-blockers directly eliminate every mechanism causing pelvic pain.
Can anti-inflammatory medicines help?
Nonsteroidal anti-inflammatory drugs can provide symptom improvement for some patients.
Current EAU evidence reports a moderate overall treatment effect for NSAIDs in primary prostate pain syndrome.
They are generally considered one component of treatment rather than a long-term cure, and gastrointestinal, kidney, cardiovascular and other medication risks must be considered.
What about medicines for nerve-related pain?
Neuropathic pain features may lead clinicians to consider treatments used for nerve-related pain in selected patients.
However, the evidence differs substantially by medicine.
The fact that pain may have a neurological component does not mean every neuropathic-pain drug has proven efficacy in CP/CPPS.
For example, current EAU evidence does not support pregabalin as an effective general treatment for primary prostate pain syndrome.
Should antibiotics be used?
This requires careful interpretation.
Some guideline evidence supports a limited antimicrobial trial in selected treatment-naïve patients early in the course of prostate pain syndrome.
That is very different from repeatedly prescribing antibiotics for years whenever pelvic pain returns.
The 2025 AUA guideline specifically advises clinicians to refrain from repeated courses of antimicrobial therapy for CP/CPPS when urine cultures and sexually transmitted infection testing are negative.
Repeated empirical antibiotics can expose patients to:
- drug adverse effects;
- antimicrobial resistance;
- microbiome disruption;
- and delayed treatment of the actual pain mechanism.
If recurrent infection is demonstrated, the diagnosis should instead be reconsidered in the direction of chronic bacterial prostatitis.
Can lifestyle changes help?
Yes, when they are individualized.
Potential strategies include:
- regular tolerable physical activity;
- avoiding prolonged inactivity;
- adjusting sitting when it clearly provokes perineal pain;
- maintaining sleep routines;
- identifying—not universally banning—foods or drinks that repeatedly trigger symptoms;
- managing constipation or bowel straining when relevant;
- and pacing activity during major pain flares.
There is no single “prostatitis diet” proven to work for every patient.
What role can psychological treatment play?
Chronic-pain-focused psychological treatment can help patients whose pain is accompanied by substantial fear, anxiety, depressive symptoms or major functional disruption.
This is not because the pain is imaginary.
Cognitive-behavioral strategies can help reduce pain-related fear, catastrophizing, avoidance and the life disruption that develops around chronic symptoms.
EAU guidance recommends referral for chronic-pelvic-pain-focused psychological treatment when significant psychological distress is present.
Are surgery or prostate procedures used to treat CP/CPPS?
Not simply to remove chronic pelvic pain.
Current EAU evidence does not support prostate surgery such as TURP or radical prostatectomy as treatment for primary prostate pain syndrome.
The 2025 AUA guideline likewise advises against prostate surgery solely to relieve chronic pelvic pain unless another legitimate indication—such as bladder outlet obstruction or prostate cancer—is present.
Can CP/CPPS get better?
Yes.
Improvement may be gradual rather than immediate.
Useful treatment goals include:
- lower pain intensity;
- fewer or shorter flares;
- improved urination;
- less painful ejaculation;
- better sleep;
- return to exercise, work and sexual activity;
- less fear of symptoms;
- and improved quality of life.
For a chronic pain syndrome, meaningful recovery does not always require that every sensation disappears before function improves.
When should the diagnosis be reconsidered?
The clinical picture should be reassessed if new features develop, especially:
- fever or shaking chills;
- new positive urine cultures;
- blood in the urine;
- progressive inability to urinate;
- a new testicular mass;
- unexplained weight loss;
- progressive neurological symptoms;
- or another major change from the person’s established chronic pattern.
New systemic illness should not automatically be attributed to an existing CP/CPPS diagnosis.

Educational disclaimer: This article provides general medical education about chronic prostatitis/chronic pelvic pain syndrome. Chronic pelvic pain has several possible causes, and symptoms should not be self-diagnosed as CP/CPPS without appropriate medical evaluation. New fever, shaking chills, inability to urinate, blood in the urine, a testicular mass, progressive neurological symptoms or a major change from a person’s usual chronic pattern requires medical assessment for other conditions.
