Prostatitis is a term used to describe inflammation of the prostate gland. Depending on the type of prostatitis, it may temporarily affect sperm quality and male fertility, particularly if inflammation is severe or prolonged. However, for most men these changes are temporary rather than permanent, and fertility often improves once the inflammation settles.
Many men also worry that prostatitis could eventually develop into prostate cancer. This is understandable because both conditions can cause similar symptoms and both may increase the prostate-specific antigen (PSA) blood test. Fortunately, there is currently no convincing evidence that prostatitis directly causes prostate cancer. While chronic inflammation has been investigated as a possible contributor to cancer development, current research has not demonstrated that prostatitis itself transforms into prostate cancer.
One of the challenges is that prostatitis and prostate cancer can look similar. Both may cause urinary symptoms, pelvic discomfort and a raised PSA. This is why further investigations such as multiparametric MRI (mpMRI) and, in selected cases, a prostate biopsy are sometimes required to distinguish between the two.
This article explains what the latest evidence tells us about prostatitis, fertility and prostate cancer, why prostatitis can affect sperm quality, when these changes are reversible and how doctors investigate men whose symptoms overlap with prostate cancer.
Can Prostatitis Cause Infertility or Prostate Cancer?
The short answer is yes and no.
What is prostatitis?
Prostatitis means inflammation of the prostate gland. The prostate is a small gland located below the bladder that produces part of the fluid found in semen. Although the name suggests a single disease, prostatitis actually describes several different conditions that have different causes, treatments and long-term outcomes.
The four recognised categories are:
- Acute bacterial prostatitis – a sudden bacterial infection causing severe urinary symptoms, fever and pain. This requires urgent antibiotic treatment.
- Chronic bacterial prostatitis – a persistent bacterial infection causing recurrent urinary tract infections and pelvic discomfort.
- Chronic prostatitis/chronic pelvic pain syndrome (CPPS) – the commonest form, accounting for around 90–95% of prostatitis diagnoses. Most men with CPPS do not have an ongoing bacterial infection. Instead, symptoms are thought to result from a combination of pelvic floor muscle dysfunction, nerve sensitisation, inflammation and lower urinary tract dysfunction.
- Asymptomatic inflammatory prostatitis – inflammation is found incidentally, usually during investigations for another condition, without causing symptoms.
Understanding which type of prostatitis you have is essential because the impact on fertility, PSA and long-term management differs considerably.
Can prostatitis cause infertility?
This question is one of the commonest concerns among younger men diagnosed with prostatitis.
The reassuring news is that most men with prostatitis do not become permanently infertile.
However, inflammation of the prostate can temporarily affect several aspects of sperm function, particularly when symptoms are severe, prolonged or associated with bacterial infection.
The prostate contributes approximately 20–30% of the fluid that makes up semen. This fluid contains nutrients, enzymes and protective substances that help sperm survive, move efficiently and fertilise an egg.
When the prostate becomes inflamed, the composition of this fluid may change. Inflammatory cells release chemicals known as reactive oxygen species (ROS). In small amounts these molecules are normal, but when present in excess they can damage sperm membranes and genetic material.
Researchers have shown that inflammation may lead to:
- Reduced sperm motility (how well sperm swim)
- Increased abnormal sperm shape (morphology)
- Higher levels of sperm DNA fragmentation
- Reduced semen quality
- Increased oxidative stress within semen
These changes do not necessarily mean that a man is infertile. Instead, they may reduce the likelihood of conception while inflammation is active.
Importantly, many of these changes improve after appropriate treatment and resolution of inflammation.
How does prostatitis affect sperm?
To understand why prostatitis may influence fertility, it is helpful to understand how healthy sperm function.
For natural conception to occur, sperm need to do the following:
- Be produced in sufficient numbers.
- Swim effectively through the female reproductive tract.
- Have a normal structure.
- Carry intact genetic material.
- Survive long enough to fertilise the egg.
Inflammation within the prostate can interfere with several of these processes.
Reduced sperm motility
Sperm motility refers to how effectively sperm move.
Healthy sperm must swim through the cervix, uterus and fallopian tubes to reach the egg. Even if sperm numbers are normal, poor movement can reduce fertility.
Inflammatory chemicals released during prostatitis may damage the sperm tail or alter the surrounding seminal fluid, making it more difficult for sperm to move efficiently.
Several studies have demonstrated lower sperm motility in men with chronic prostatitis compared with healthy men, although the severity varies considerably between individuals.
Changes in sperm morphology
Sperm morphology describes the size and shape of sperm.
A normal sperm has an oval head, a well-formed midpiece and a long tail that propels it forwards.
Inflammation and oxidative stress may increase the proportion of abnormally shaped sperm. Although many men naturally have a mixture of normal and abnormal sperm, a significant reduction in normal forms may reduce fertility.
Fortunately, sperm production is a continuous process. New sperm are produced approximately every 74 days, meaning improvements in inflammation may be reflected in semen quality over the following two to three months.
Can prostatitis damage sperm DNA?
One of the most important advances in fertility research has been the recognition of sperm DNA fragmentation.
Even when sperm appear normal under the microscope, inflammation may cause microscopic damage to the DNA contained within the sperm head.
High levels of oxidative stress caused by inflammation can increase DNA fragmentation, which has been associated with reduced fertility, lower pregnancy rates and, in some studies, a higher risk of miscarriage.
Not every man with prostatitis develops significant DNA damage, but this mechanism helps explain why chronic inflammation may temporarily affect fertility even when standard semen analysis appears relatively normal.
This is known as sperm DNA fragmentation.
DNA fragmentation has become an area of increasing interest because standard semen analysis cannot detect it.
High levels of DNA fragmentation have been associated with:
- Reduced natural pregnancy rates.
- Lower fertilisation rates during IVF.
- Reduced embryo quality.
- Increased miscarriage rates in some studies.
Fortunately, sperm DNA damage caused by inflammation is often reversible. As inflammation improves and new sperm are produced, DNA quality may recover over the following few months.
Should I have sperm DNA fragmentation testing?
For most men with prostatitis, no.
Routine sperm DNA fragmentation testing is not recommended for every patient because the test is expensive, not universally available and its role remains uncertain in many clinical situations.
However, it may be considered in selected men, particularly if:
- Standard semen analysis is normal despite persistent infertility.
- There have been repeated miscarriages without another explanation.
- Previous IVF or ICSI treatment has been unsuccessful.
- There is persistent severe prostatitis or recurrent infection.
- Other risk factors for oxidative stress are present, such as smoking or varicocele.
The results should always be interpreted alongside a complete fertility assessment rather than in isolation.
What is leukocytospermia?
Another important finding in some men with prostatitis is leukocytospermia, also known as pyospermia. This means that semen contains an increased number of white blood cells, the immune cells responsible for fighting infection and inflammation.
Although white blood cells play an essential role in protecting the body, excessive numbers within semen may contribute to fertility problems by releasing large amounts of reactive oxygen species.
Leukocytospermia is more commonly seen in bacterial prostatitis, but it may also occur in some men with non-bacterial inflammatory conditions.
Importantly, the presence of white blood cells in semen does not automatically mean there is an active bacterial infection. In many cases, they simply reflect ongoing inflammation.
Does chronic prostatitis (CPPS) affect fertility in the same way as bacterial prostatitis?
Not necessarily.
Men with chronic bacterial prostatitis are generally more likely to experience inflammatory changes within the prostate fluid because bacteria trigger a prolonged immune response.
In contrast, chronic prostatitis/chronic pelvic pain syndrome (CPPS) is usually not caused by infection. Instead, symptoms often arise from pelvic floor muscle dysfunction, altered pain processing and lower urinary tract dysfunction.
Although some studies suggest that men with CPPS may have increased oxidative stress within semen, the evidence linking CPPS alone to significant infertility is much weaker than for chronic bacterial prostatitis.
For most men with CPPS, the overall outlook for fertility remains reassuring.
Is infertility caused by prostatitis permanent?
For the vast majority of men, the answer is no.
This is one of the biggest misconceptions surrounding prostatitis. Many men worry that once inflammation affects the prostate, they will never be able to father children. Fortunately, this is rarely the case.
Unlike conditions that permanently damage the testicles, prostatitis mainly affects the environment in which sperm travel rather than permanently stopping sperm production.
The prostate provides nutrients, enzymes and protective substances that help sperm survive after ejaculation. When the prostate becomes inflamed, the composition of this fluid changes. Once the inflammation settles, the prostate often returns to producing healthier seminal fluid, allowing sperm function to improve.
This explains why fertility often recovers after successful treatment.
Several studies have shown improvements in semen quality once infection or inflammation resolves, although the degree of recovery varies depending on:
- The type of prostatitis.
- How long symptoms have been present.
- The severity of inflammation.
- Whether other male fertility problems are also present.
- Age and general health.
For men with chronic prostatitis/chronic pelvic pain syndrome (CPPS), there is currently no convincing evidence that the condition causes permanent infertility in most cases. While semen quality may be temporarily affected in some men, particularly during symptom flare-ups, long-term irreversible infertility appears to be uncommon.
This is reassuring because CPPS is often a chronic condition that fluctuates over time. Even men who have experienced symptoms for several years frequently go on to father children naturally.
Can fertility improve after prostatitis treatment?
In many cases, yes.
The outlook is generally encouraging because sperm are continually produced throughout adult life. A complete cycle of sperm production takes approximately 74 days, followed by around two weeks for maturation and transport through the reproductive tract.
This means that improvements in semen quality are often not immediate. Even after successful treatment, it may take two to three months before healthier sperm are present in the ejaculate.
Clinical studies have reported improvements in:
- Sperm motility.
- Semen quality.
- Oxidative stress markers.
- White blood cell counts in semen.
- DNA integrity in selected men.
The greatest improvements are generally seen when the underlying cause of inflammation is successfully addressed. In bacterial prostatitis this may involve antibiotic treatment, whereas men with CPPS often benefit from a multimodal approach that includes pelvic floor physiotherapy, symptom-directed medication, regular exercise and lifestyle measures.
The reassuring message for most patients is that prostatitis is far more likely to cause temporary changes in fertility than permanent infertility. With appropriate treatment and time for new sperm to develop, many men experience significant improvements in semen quality and go on to achieve successful natural conception.
Acute bacterial prostatitis
When prostatitis is caused by a bacterial infection, appropriate antibiotics usually eliminate the infection. As inflammation settles, semen quality often improves over the following weeks to months.
Chronic bacterial prostatitis
This condition can be more challenging because bacteria may persist within the prostate despite treatment.
Successful treatment may improve:
- Sperm motility.
- Semen quality.
- Oxidative stress.
- DNA fragmentation.
Some men require prolonged antibiotic treatment because antibiotics penetrate the prostate poorly.
Chronic prostatitis/chronic pelvic pain syndrome (CPPS) treatment overview
Treatment focuses on improving symptoms rather than eliminating bacteria.
Depending on the individual, management may include:
- Pelvic floor physiotherapy.
- Tadalafil.
- Alpha-blockers.
- Anti-inflammatory treatments where appropriate.
- Stress reduction.
- Regular exercise.
- Dietary modification.
Although these treatments primarily improve pain and urinary symptoms, improving pelvic muscle function and reducing inflammation may also create a healthier environment for sperm.
More research is still needed to determine exactly how much CPPS treatment improves fertility.
Can prostatitis reduce sperm count?
It can, but this is not always the case.
One of the challenges in studying prostatitis is that research findings are sometimes inconsistent.
Some studies have demonstrated lower sperm concentrations in men with chronic prostatitis, while others have found little difference compared with healthy controls.
The reason is that prostatitis affects men differently.
Some experience predominantly:
- Pelvic pain.
- Urinary symptoms.
- Erectile dysfunction.
Others develop more obvious inflammatory changes within the semen.
Overall, current evidence suggests that prostatitis is more likely to affect sperm quality than sperm quantity.
This means that prostatitis may affect movement, function and DNA integrity more consistently than the absolute number of sperm.
Can prostatitis affect sperm DNA?
Yes.
One of the most important discoveries in male fertility research has been the recognition that sperm may appear normal under the microscope while carrying microscopic damage within their genetic material.
This is known as sperm DNA fragmentation.
Inflammation increases the production of harmful molecules called reactive oxygen species (ROS).
When these exceed the body's natural antioxidant defences they create oxidative stress, damaging cell membranes, proteins and DNA.
Higher levels of sperm DNA fragmentation have been associated with:
- Reduced natural conception rates.
- Lower success rates during IVF.
- Reduced embryo quality.
- Higher miscarriage rates in some studies.
Not every man with prostatitis develops significant DNA damage.
However, this mechanism helps explain why some couples experience difficulty conceiving despite apparently normal semen analysis.
Research into antioxidant treatments aimed at reducing oxidative stress remains ongoing.
Should I have a semen analysis if I have prostatitis?
Not necessarily.
A semen analysis measures several aspects of semen and sperm health, including:
- Semen volume.
- Sperm concentration.
- Motility.
- Morphology.
- White blood cells.
- Other laboratory parameters.
For many men with prostatitis, a semen analysis is not routinely required.
It becomes more useful when:
- A couple has been trying unsuccessfully to conceive.
- Symptoms have persisted for a prolonged period.
- Recurrent bacterial prostatitis is present.
- There are concerns regarding fertility.
A normal semen analysis is reassuring, but it does not guarantee fertility.
Likewise, an abnormal result does not necessarily mean that pregnancy cannot occur naturally.
Because sperm production takes approximately 74 days, repeat testing is often recommended before drawing conclusions, particularly if inflammation has recently been treated.
Can prostatitis affect IVF or ICSI success rates?
For most couples, prostatitis does not mean that IVF (in vitro fertilisation) or ICSI (intracytoplasmic sperm injection) will be needed. Many men with prostatitis continue to conceive naturally, particularly once inflammation has settled and symptoms improve.
However, in some men, prolonged inflammation may temporarily affect sperm quality. Changes in sperm motility, increased oxidative stress (an imbalance between harmful molecules and the body's natural antioxidant defences) and higher levels of sperm DNA fragmentation (damage to the genetic material within sperm) may reduce the chances of successful fertilisation.
When fertility problems persist despite appropriate treatment, a fertility specialist may recommend assisted reproductive techniques.
With IVF, eggs are mixed with sperm in the laboratory to encourage fertilisation. With ICSI, a single healthy sperm is injected directly into an egg. ICSI is often considered when sperm motility, sperm count or sperm quality are significantly reduced.
Current evidence suggests that treating prostatitis, reducing inflammation and improving semen quality before assisted reproduction may improve outcomes in selected men, although the evidence remains mixed and depends on the underlying cause of infertility. Importantly, many couples achieve successful pregnancies following appropriate management of prostatitis without requiring assisted reproduction.
If conception has not occurred after a reasonable period of trying, a comprehensive fertility assessment should evaluate both partners, as male and female factors commonly contribute together. Focusing solely on prostatitis risks overlooking other treatable causes of infertility.
Can prostatitis affect sexual function?
Yes.
Although infertility and erectile dysfunction are often discussed separately, they are closely related in men with chronic prostatitis.
Studies consistently show that men with CPPS report higher rates of:
- Erectile dysfunction.
- Reduced sexual desire.
- Pain during ejaculation.
- Pain after ejaculation.
- Reduced sexual confidence.
- Anxiety surrounding intercourse.
There are several reasons why this occurs.
Persistent pelvic pain naturally reduces sexual desire.
Pelvic floor muscle tension may interfere with normal erections and ejaculation.
Fear of triggering pain may lead some men to avoid sexual activity altogether.
Over time this can affect confidence, relationships and overall quality of life.
The good news is that successful treatment of CPPS often improves sexual function as symptoms improve.
Can prostatitis affect testosterone?
Many men with chronic prostatitis or chronic prostatitis/chronic pelvic pain syndrome (CPPS) worry that their symptoms mean they have low testosterone. This is understandable because tiredness, reduced sex drive, erectile dysfunction and low mood can occur in both conditions.
The reassuring news is that prostatitis does not usually reduce testosterone levels directly. Current evidence does not show that inflammation of the prostate causes the testicles to stop producing testosterone.
However, prostatitis can indirectly affect how men feel, producing symptoms that are often mistaken for testosterone deficiency.
Persistent pelvic pain can disrupt sleep, reduce physical activity and make regular exercise difficult. Chronic pain also places the body under continuous physical and psychological stress, which may contribute to fatigue, reduced libido and poorer sexual performance. Anxiety about persistent symptoms, concerns about fertility or fear of prostate cancer can further reduce confidence and sexual wellbeing.
Erectile dysfunction is also relatively common in men with CPPS. In many cases, this is related to pelvic floor muscle dysfunction, chronic pain, altered blood flow and psychological factors rather than low testosterone itself.
If symptoms such as reduced libido, persistent fatigue or loss of muscle strength continue despite improvement in prostatitis, a simple blood test can determine whether testosterone levels are genuinely low. It is important not to assume that prostatitis is the cause of every symptom, as hormone deficiency and prostatitis may occasionally occur together but require different treatments.
For most men, successfully treating prostatitis, improving pelvic floor function, sleeping better, exercising regularly and reducing chronic pain often lead to significant improvements in energy levels, sexual function and overall wellbeing without the need for testosterone replacement therapy.
Can prostatitis cause prostate cancer?
This is probably the question that worries patients the most.
The reassuring answer is that current evidence does not show that prostatitis directly causes prostate cancer.
Scientists have been investigating the relationship between chronic inflammation and prostate cancer for many years.
Inflammation is known to contribute to the development of some cancers elsewhere in the body.
For example, chronic inflammatory bowel disease increases the risk of colorectal cancer, while chronic viral hepatitis increases the risk of liver cancer.
Researchers therefore questioned whether chronic inflammation within the prostate might produce similar effects.
Some observational studies have reported an association between previous prostatitis and prostate cancer.
However, association does not prove causation.
There are several reasons why these studies should be interpreted carefully.
Men with prostatitis are:
- More likely to visit a urologist.
- More likely to undergo PSA testing.
- More likely to have MRI scans.
- More likely to undergo prostate biopsy.
As a result, prostate cancer may simply be detected more frequently, rather than occurring more often.
This is known as detection bias.
When researchers account for these factors, the evidence supporting prostatitis as a direct cause of prostate cancer becomes much weaker.
Current European and international guidelines therefore do not regard prostatitis as a proven cause of prostate cancer.
Instead, prostatitis should be viewed as a condition that can mimic prostate cancer, particularly because both conditions may produce similar symptoms and temporarily raise PSA levels.
Can prostatitis increase PSA?
Yes. Prostatitis is one of the commonest non-cancerous causes of a raised prostate-specific antigen (PSA) blood test.
PSA is a protein produced by cells within the prostate gland. Although it is widely used to help detect prostate cancer, PSA is not a cancer-specific test. Any condition that disrupts the normal structure of the prostate can allow more PSA to leak into the bloodstream.
This includes:
- Acute bacterial prostatitis.
- Chronic bacterial prostatitis.
- Chronic prostatitis/chronic pelvic pain syndrome (CPPS), although usually to a lesser degree.
- Benign enlargement of the prostate.
- Recent ejaculation.
- Recent urinary catheterisation.
- Vigorous cycling.
- Recent prostate biopsy or surgery.
The largest PSA rises are usually seen in acute bacterial prostatitis, where inflammation is severe. In some men, PSA levels may increase dramatically before gradually returning towards their previous baseline once the infection has resolved.
For men with CPPS, PSA elevations are generally smaller and less predictable.
The important point is that a raised PSA does not automatically mean prostate cancer.
This is one reason why PSA should never be interpreted in isolation. Age, symptoms, prostate examination, MRI findings, PSA density and previous PSA measurements all contribute to understanding an individual's risk.
If PSA is measured during an episode of prostatitis, it is often appropriate to repeat the test after the inflammation has settled, as many men experience a significant reduction.
Can prostatitis look like prostate cancer?
Unfortunately, yes.
This is one of the reasons why prostatitis can be such a worrying condition for patients.
Both prostatitis and prostate cancer may cause:
- A raised PSA.
- Urinary frequency.
- Urinary urgency.
- Difficulty passing urine.
- Pelvic discomfort.
- Pain during ejaculation.
On multiparametric MRI (mpMRI), prostatitis can sometimes produce areas that appear suspicious for prostate cancer because inflammation changes the appearance of prostate tissue.
Similarly, during a digital rectal examination (DRE), inflammation may occasionally make part of the prostate feel firmer than expected.
Fortunately, experienced radiologists and urologists consider the whole clinical picture rather than relying on one investigation alone.
Features such as the pattern of MRI changes, PSA density, PSA trend over time, age, symptoms and family history all help determine whether further investigation is necessary.
How do doctors tell prostatitis from prostate cancer?
Although the two conditions can overlap, modern investigations allow doctors to distinguish between them in most men.
The assessment usually begins with a careful clinical history.
Symptoms suggesting prostatitis include:
- Pelvic pain.
- Pain after ejaculation.
- Burning when passing urine.
- Symptoms that fluctuate over time.
- Previous urinary tract infections.
- Fever and feeling generally unwell in acute bacterial prostatitis.
What symptoms should I expect if I have prostate cancer
Early detection of prostate cancer is often challenging due to the absence or ambiguity of symptoms. When symptoms do occur, they are frequently similar to those caused by benign prostate enlargement rather than prostatitis. However, there are five primary indicators that raise suspicion:
2. Blood in the urine or bloody semen
5. Lower back pain
Your doctor may ask for the following tests;
PSA blood test
A PSA result is interpreted alongside age, prostate size and previous PSA values rather than in isolation.
Digital rectal examination (DRE)
This allows assessment of the size, shape and consistency of the prostate.
Multiparametric MRI (mpMRI)
MRI has transformed prostate cancer diagnosis.
It helps identify areas that may represent clinically significant cancer while also demonstrating changes that are more suggestive of inflammation.
MRI has greatly reduced the number of unnecessary prostate biopsies performed in men with raised PSA.
Prostate biopsy
If MRI and PSA suggest a significant risk of prostate cancer, a biopsy may be recommended.
A biopsy remains the only way to confirm or exclude prostate cancer with certainty.
When should prostatitis be investigated further?
Most men with prostatitis do not require extensive investigations.
However, further assessment becomes important when symptoms or test results suggest another condition may also be present.
Additional investigation may be recommended if there is:
- A persistently raised or rising PSA after inflammation has settled.
- An abnormal prostate examination.
- A suspicious lesion on MRI.
- Blood in the urine.
- Recurrent urinary tract infections.
- Difficulty emptying the bladder.
- Weight loss without explanation.
- Bone pain.
- Failure to improve despite appropriate treatment.
- Diagnostic uncertainty.
These situations do not necessarily mean that prostate cancer is present, but they justify further assessment to exclude significant disease.
What do the European Association of Urology (EAU) Guidelines say?
The European Association of Urology (EAU) recognises that prostatitis is not a single disease but a group of conditions with different causes and treatment strategies.
For chronic prostatitis/chronic pelvic pain syndrome (CPPS), the guidelines recommend a multimodal approach, as no single treatment is effective for every patient.
Management should be individualised according to the dominant symptoms and may include:
- Pelvic floor physiotherapy.
- Pain management.
- Lifestyle modification.
- Alpha-blockers in selected men.
- Phosphodiesterase type 5 inhibitors, such as tadalafil, may be appropriate.
- Psychological support when chronic pain significantly affects quality of life.
Importantly, the guidelines do not consider prostatitis to be a proven cause of prostate cancer.
Similarly, while prostatitis may affect semen quality in some men, the evidence does not support the conclusion that most men will develop permanent infertility.
This is reassuring for patients and reflects the growing understanding that prostatitis should be managed according to its underlying mechanisms rather than using a single treatment for all men.
Are you looking for a consultant urologist who specialises in prostatitis and prostate cancer in Sussex?
Mr Edward Calleja is a Consultant Urological Surgeon specialising in chronic prostatitis/chronic pelvic pain syndrome (CPPS), prostate cancer and men's urinary symptoms. He regularly assesses men with persistent pelvic pain, raised PSA, urinary symptoms and concerns about fertility using an evidence-based, personalised approach.
Because prostatitis can have several contributing factors, including pelvic floor dysfunction, inflammation, lower urinary tract symptoms and nerve sensitisation, management focuses on identifying the underlying causes rather than relying on a single treatment. Treatment plans are tailored to the individual and follow the latest European Association of Urology (EAU) guidance, combining therapies where appropriate to improve symptoms and quality of life.
Myth vs Fact: Common misconceptions about prostatitis
Myth: Prostatitis causes prostate cancer.
Fact: Current evidence does not show that prostatitis directly causes prostate cancer. Although both conditions may raise PSA levels and sometimes produce similar symptoms, they are separate conditions. Chronic inflammation has been studied extensively, but a direct cause-and-effect relationship has not been proven.
Myth: Every raised PSA means prostate cancer.
Fact: A raised PSA does not automatically indicate cancer. PSA can increase because of prostatitis, an enlarged prostate, recent ejaculation, urinary infection, cycling or recent medical procedures involving the prostate. PSA should always be interpreted alongside symptoms, prostate examination, MRI findings and PSA trends over time.
Myth: Chronic prostatitis always causes infertility.
Fact: Most men with prostatitis remain fertile. While inflammation may temporarily reduce sperm quality, motility or DNA integrity in some men, permanent infertility is uncommon. Many men go on to conceive naturally once inflammation has improved.
Myth: If antibiotics do not work, nothing else will help.
Fact: Most men with chronic prostatitis/chronic pelvic pain syndrome (CPPS) do not have an ongoing bacterial infection. Treatments such as pelvic floor physiotherapy, tadalafil, alpha-blockers, lifestyle modification and pain management often play a much greater role than repeated courses of antibiotics.
Myth: Prostatitis only affects older men.
Fact: Prostatitis can affect men of almost any adult age and is one of the most common urological conditions in younger and middle-aged men. CPPS, in particular, is frequently diagnosed in men under 50.
Myth: Prostatitis is always caused by an infection.
Fact: Approximately 90–95% of prostatitis diagnoses are chronic prostatitis/chronic pelvic pain syndrome (CPPS), which is usually not caused by a bacterial infection. Instead, symptoms often result from a combination of pelvic floor muscle dysfunction, nerve sensitisation, inflammation and lower urinary tract dysfunction.
Myth: Prostatitis will shorten my life.
Fact: Although prostatitis can significantly affect quality of life, work, relationships and mental wellbeing, it is not generally associated with a reduced life expectancy. With an accurate diagnosis and an individualised treatment plan, most men can achieve significant improvements in their symptoms and daily functioning.
Frequently asked questions about prostatitis, infertility and prostate cancer
Can prostatitis make you infertile?
It can temporarily affect fertility in some men by reducing sperm quality, but permanent infertility is uncommon.
Does chronic prostatitis permanently damage sperm?
Current evidence suggests that, for most men, any changes in sperm quality improve once inflammation settles.
Can prostatitis reduce sperm count?
It may, although prostatitis is more likely to affect sperm function than the overall number of sperm produced.
Can prostatitis affect sperm motility?
Yes. Inflammation may reduce the ability of sperm to swim effectively.
Can prostatitis damage sperm DNA?
It can increase oxidative stress, which may increase sperm DNA fragmentation in some men.
Should I have a semen analysis?
A semen analysis is usually recommended only when there are concerns about fertility or difficulty conceiving.
Can prostatitis cause prostate cancer?
There is no convincing evidence that prostatitis directly causes prostate cancer.
Can prostatitis increase PSA?
Yes. Inflammation of the prostate is a well-recognised cause of raised PSA.
Can prostatitis look like prostate cancer on MRI?
Yes. Inflammation may occasionally produce MRI appearances that resemble prostate cancer, which is why MRI findings must always be interpreted alongside the clinical picture.
Will prostatitis shorten my life?
No. Prostatitis can significantly affect quality of life, but it is not generally associated with a reduced life expectancy.
Can I still have children if I have prostatitis?
Most men with prostatitis remain fertile, and many who experience temporary changes in semen quality go on to conceive naturally.
Can prostatitis cause infertility or prostate cancer? Key points to remember
Prostatitis is a common condition that can understandably cause anxiety, particularly when men worry about future fertility or prostate cancer. The reassuring news is that most men do not develop permanent infertility, and current evidence does not support the idea that prostatitis directly causes prostate cancer.
Inflammation within the prostate can temporarily affect sperm quality by increasing oxidative stress and altering the composition of seminal fluid. These changes may reduce fertility while inflammation is active, but they are often reversible once the underlying condition improves.
Prostatitis can also raise PSA and mimic prostate cancer, making careful assessment essential. Modern investigations, including PSA testing, multiparametric MRI and, where appropriate, prostate biopsy, allow doctors to distinguish between these conditions in most men.
Understanding the type of prostatitis is essential for appropriate treatment. Whether symptoms are caused by a bacterial infection or chronic pelvic pain syndrome (CPPS), management should be individualised and based on the latest clinical evidence.
