Do Guys Get Utis? What Research Says

Yes, men get UTIs. The idea that urinary tract infections are a women’s problem is one of the most persistent myths in everyday health. Men have shorter, wider urethras than women, and that anatomy does make infection less common. But “less common” is not “rare,” and it is not “never.” Men account for a meaningful share of urinary tract infections, and when a man does get one, the cause and the right response can look quite different from the typical female case.

Research consistently shows that UTIs in men are less frequent than in women but often more complicated. Many are tied to an underlying problem — an enlarged prostate, a kidney stone, or a catheter — rather than to simple anatomy alone. That distinction matters, because it changes how a man should think about symptoms, testing, and treatment.

Why Do Men Get UTIs If Their Anatomy Is Different?

Anatomy explains most of the difference in how often men and women get UTIs. A woman’s urethra is short and sits close to the anus, so bacteria have a short, easy path to the bladder. A man’s urethra is longer and the distance to the bladder is greater, which makes it harder for bacteria to travel upward. This is the main reason UTIs are far more common in women.

But the male urinary tract has its own vulnerabilities. The prostate surrounds the urethra just below the bladder. When the prostate enlarges — as it commonly does with age — it can slow or block urine flow. Urine that does not fully empty gives bacteria more time to multiply. This is why benign prostatic enlargement is one of the most common underlying factors in UTIs in older men.

There is a useful distinction worth knowing. In women, most UTIs are “uncomplicated” — an infection in an otherwise healthy urinary tract. In men, clinicians often treat a UTI as “complicated” by default, because it so often signals something else going on. That label is not about severity of symptoms. It is about the likelihood that an underlying cause needs to be found.

What Causes UTIs in Men?

Bacteria cause the great majority of UTIs in men, most often Escherichia coli that travels up the urethra. In many cases the trigger is something that disrupts normal urine flow or introduces bacteria into the tract. The most common contributors include:

• Enlarged prostate — slows urine flow and prevents full bladder emptying
• Urinary catheters — a well-established risk factor, especially with longer use
• Kidney or bladder stones — can trap bacteria and block flow
• Diabetes — higher urine sugar and altered immune function can raise risk
• Narrowing of the urethra (stricture) — restricts urine flow
• Recent urinary procedures — instrumentation can introduce bacteria
• Weakened immune function — from illness or certain medications

Sexual activity can also move bacteria toward the urethra, and this is a recognized route of infection in men as well as women. It is not the only route, and it is not the main explanation for most UTIs in older men. For younger men without an enlarged prostate, sexual activity and sexually transmitted infections become more relevant considerations.

One point that gets lost: not every UTI in a man points to a hidden structural problem. Some are straightforward infections. But because the odds of an underlying cause are higher in men, clinicians tend to look harder rather than assume a simple explanation.

What Are the Symptoms of a UTI in Men?

The core symptoms of a bladder infection are similar in men and women. The most common include a burning or stinging sensation when urinating, a frequent and urgent need to urinate, and cloudy or strong-smelling urine. Some men notice blood in the urine or a feeling of pressure in the lower abdomen.

Men can also develop symptoms that point to the prostate or the upper urinary tract. These are worth knowing because they change the picture:

• Fever and chills — suggest the infection may have moved beyond the bladder
• Pain in the back or side — can indicate a kidney infection
• Pelvic or perineal pain — sometimes points to prostate involvement
• Difficulty urinating or a weak stream — often tied to an enlarged prostate

Fever, chills, and back or side pain are the symptoms that should prompt prompt medical attention. A kidney infection is more serious than a bladder infection and needs treatment without delay. This is not a situation to watch and wait on.

How Is a UTI Diagnosed in Men?

Diagnosis usually starts with a urine test. A urinalysis can detect signs of infection such as white blood cells, and a urine culture can identify the specific bacteria and which antibiotics are likely to work. In men, a culture is often especially useful because it guides treatment and helps confirm the diagnosis.

Because UTIs in men frequently have an underlying cause, clinicians may look further. Depending on the situation, this can include:

• A physical exam, sometimes including a prostate exam
• Imaging such as an ultrasound to check for blockages or stones
• Blood tests, particularly if there is fever or signs of a more serious infection
• Evaluation for sexually transmitted infections in younger men or when symptoms suggest it

How far the workup goes depends on the man’s age, how many infections he has had, and whether there are signs of a complication. A single uncomplicated infection in a healthy younger man may need less investigation than repeated infections in an older man with urinary symptoms.

How Are UTIs Treated in Men?

Bacterial UTIs in men are treated with antibiotics. The choice and duration depend on the specific bacteria, the man’s health, and whether the infection is complicated. Clinicians generally favor a urine culture to guide the choice, because resistance to common antibiotics is a real and growing issue.

It is worth being honest about what the evidence does and does not show. Antibiotics are established as the effective treatment for bacterial UTIs. What varies is which antibiotic and for how long, and that is a clinical decision based on culture results and the individual case — not something to self-manage. Men should not assume a short course is always enough; complicated infections often need longer treatment, and some clinicians treat male UTIs more aggressively than uncomplicated female cases for this reason.

For infections tied to an underlying cause, treating the infection is only part of the job. If an enlarged prostate, a stone, or a catheter is driving the problem, addressing that factor reduces the chance of recurrence. Pain relief and drinking enough fluids support comfort, but they do not replace antibiotics for a bacterial infection.

When Should a Man See a Doctor?

Any man with symptoms of a UTI should see a clinician rather than wait it out. The symptoms themselves are uncomfortable, and untreated infections can spread. The clearest reasons to seek care quickly — or urgently — include fever, chills, back or side pain, vomiting, or blood in the urine.

Recurring infections deserve attention too. If a man has UTIs that keep coming back, that pattern is a signal to look for an underlying cause rather than simply treating each one in isolation. Repeated infections can point to a prostate problem, a stone, or another issue that has not yet been identified.

A word of caution about self-treatment. Over-the-counter products marketed for urinary discomfort may ease symptoms, but they do not treat a bacterial infection. Relying on them can delay proper care. This is one area where the honest advice is simple: symptoms of a UTI in a man are a reason to get evaluated, not to wait and see.

Can UTIs in Men Be Prevented?

Some prevention steps are well established and low-risk. Drinking enough fluids helps flush the urinary tract. Urinating when the urge arises rather than holding it in supports normal bladder emptying. Good hygiene matters, and for men with catheters, proper catheter care is a recognized way to lower risk.

For men whose infections are linked to an enlarged prostate or another structural issue, the most effective prevention is treating that underlying problem. General healthy habits — managing diabetes well, staying hydrated — support urinary health, though the evidence that any single lifestyle change prevents UTIs is limited and varies by individual.

It is fair to say that no diet, supplement, or home remedy has strong clinical evidence for preventing UTIs in men. Some products are marketed with confident claims. The research does not back those claims strongly, and men should treat prevention marketing with skepticism.

How Common Are UTIs in Men Compared With Women?

UTIs are substantially more common in women, and that gap is well documented. The shorter female urethra is the main reason. But the frequency in men rises with age, largely because prostate enlargement becomes more common and because catheter use increases in older adults.

The practical takeaway is not a number but a mindset. A UTI in a man is common enough to take seriously and uncommon enough that it often warrants a closer look. The two ideas are not in conflict — they are both true at once.
