Do Men Get UTIs? Male UTI Symptoms and When It’s a UTI vs an STI

Intro

Yes, men can get UTIs, but they’re less common in men than in women, which is exactly why urinary symptoms in men deserve a little more attention. In younger men, burning or discomfort when urinating can sometimes be linked to urethritis (often STI-related) rather than a bladder infection. In older men, issues like an enlarged prostate can make it harder to empty the bladder fully, which increases the chance of infection.

This guide is designed to help you quickly understand:

• What a UTI in men looks like
• Which symptoms are “routine” vs urgent
• How to think about UTI vs STI without guessing.

Quick answer 

Yes, men can get UTIs, but they’re less common and often worth checking properly. Symptoms may include burning when urinating, frequent/urgent urination, cloudy or strong-smelling urine, lower abdominal discomfort, and sometimes blood in urine. Fever, chills, back/flank pain, or vomiting can suggest a more serious infection (kidney involvement) and needs prompt medical review. In men, urinary symptoms can also be caused by STIs or prostate issues, so testing is important before self-treating.

What is a UTI in men? 

A UTI (urinary tract infection) usually means bacteria have entered the urinary tract and started multiplying most commonly in the bladder. The urinary tract includes the urethra (tube that carries urine out), the bladder, the ureters, and the kidneys.

In men, doctors tend to take UTIs more seriously for a practical reason: a bladder infection is less common, so when it happens it may be linked to something that makes infection easier, such as:

• Incomplete bladder emptying (often from prostate enlargement with age)
• Urinary blockage or kidney stones
• Catheter use
• Diabetes or reduced immunity

This doesn’t mean every case is dangerous, it means the goal is to treat it properly and rule out factors that increase recurrence or complications.

UTI symptoms in men (and red flags)

Most men notice urinary symptoms first, and they usually show up in a few predictable ways.

Common symptoms (lower urinary tract / bladder-focused)

• Burning or stinging when you urinate
• Urgency (feels like you need to go immediately)
• Frequency (going often, sometimes only small amounts)
• Lower abdominal or pelvic discomfort
• Cloudy urine or stronger-than-usual urine smell
• Blood in urine (can happen should be assessed, especially if significant)

Some men may also feel discomfort in the perineal area (between scrotum and anus) or rectal pressure as this can sometimes suggest prostate involvement and should be discussed with a clinician rather than ignored.

Red flags

These symptoms raise concern for kidney involvement or a more complicated infection:

• Fever and chills.
• Back/flank pain (pain under the ribs on either side of the spine).
• Nausea or vomiting.
• Feeling markedly unwell or weak.
• Inability to pass urine.

If any of these are present, it’s safer to get a medical review quickly rather than trying to manage at home.

Common reasons why do men get UTIs?

Because UTIs are less common in men, it helps to think in terms of “what made infection easier this time?” Most of the time, it comes down to one of three things: bacteria getting access to the urinary tract, urine not draining well, or an underlying condition increasing susceptibility.

1) Age-related factors (especially prostate changes)

As men age, the prostate can enlarge (often called benign prostatic hyperplasia, or BPH). When the prostate enlarges, it can partially block urine flow and lead to incomplete bladder emptying. Stagnant urine gives bacteria more time to multiply, which increases infection risk.

Practical clue: If you have UTI symptoms plus long-term symptoms like weak stream, straining, or waking at night to urinate, mention it because treating the infection alone may not prevent recurrence if emptying remains poor.

2) Stones, blockages, or urinary tract abnormalities

Kidney stones or urinary blockages can cause urine to back up or irritate the urinary tract lining. This can make infection more likely and can also make symptoms feel more severe.

3) Catheters and recent procedures

A catheter or recent urinary procedure can increase infection risk because it can introduce bacteria into the urinary tract or disturb normal protective barriers.

4) Diabetes or reduced immunity

Higher blood sugar levels and immune changes can increase susceptibility to infection. If you have diabetes and new urinary symptoms, it’s usually better to seek assessment earlier.

5) Sexual exposure and urethritis

In younger men, “UTI-like” symptoms are sometimes not a bladder infection at all. Burning, discomfort, or urinary irritation can come from urethritis, which is often linked to STIs like chlamydia or gonorrhoea. That’s why the next section UTI vs STI is such a big part of this blog.

Is it a UTI or an STI? How to tell (without guessing)

This is the most important section for men, because the treatment and testing are different. Many men assume urinary burning automatically means a UTI, but in men it can be caused by:

• Bladder infection (UTI)
• Urethritis (often STI-related)
• Irritation/dehydration
• Prostate inflammation

A simple way to think about it

UTI (bladder-focused) often comes with:

• Urgency and frequency (feels like you constantly need to go)
• Lower abdominal discomfort
• Cloudy/strong-smelling urine
• Sometimes blood in urine

STI-related urethritis is more likely when:

• Symptoms started after a recent new partner or unprotected sex
• There’s urethral irritation that feels more “at the tip” rather than bladder pressure
• There may be discharge (not always)
• Urinary symptoms are present without the typical bladder “fullness” feeling

That said, there’s overlap so the goal isn’t self-diagnosis. The goal is to choose the right test panel based on the exposure history and symptom pattern.

Why testing matters (and why “trial antibiotics” isn’t ideal)

If symptoms are STI-related and you treat it like a UTI, you risk:

• Using the wrong antibiotics
• Delaying proper treatment
• Missing partner notification needs
• Ongoing irritation or complications

If you’re unsure, it’s usually safer to do a proper assessment and testing rather than guessing.

How UTIs are diagnosed in men (what tests doctors use)

Diagnosis is usually straightforward, but the test selection matters especially when it’s unclear whether symptoms are UTI vs STI.

1) Urine testing (the starting point)

Most clinicians begin with:

• A urine dipstick/urinalysis to look for signs of infection/inflammation
• A urine culture to identify the bacteria and guide antibiotic choice if needed

Culture is useful in men because it helps confirm that this is a bacterial UTI and not something else.

2) STI testing when appropriate

If your symptoms and exposure history suggest urethritis, clinicians may recommend STI testing (often urine or swabs depending on exposure sites). This avoids missing a treatable STI and ensures the right treatment plan.

3) Extra evaluation for recurrent or complicated cases

If UTIs are recurrent, severe, or associated with red flags, the clinician may consider:

• Prostate evaluation if prostatitis/BPH is suspected
• Imaging (to look for stones or obstruction)
• Referral to a urologist in some cases

The key idea is: in men, testing is not “overkill” it’s often what prevents recurrence and ensures the cause is treated properly.

Treatment for UTI in men (what usually happens)

Treatment depends on what’s causing your symptoms. If testing confirms a bacterial UTI, treatment is usually straightforward but in men, clinicians often take a more careful approach because the infection can sometimes be linked to the prostate or an underlying urinary issue.

If it’s confirmed as a bacterial UTI

A clinician will usually recommend:

• Antibiotics targeted to the bacteria (often guided by urine culture when available)
• Supportive steps such as hydration and avoiding bladder irritants (alcohol, excess caffeine, spicy foods) during recovery

Many people start feeling better within a couple of days of appropriate treatment, but it’s important to follow the prescribed plan so the infection clears properly.

If prostatitis is suspected

If symptoms suggest prostate inflammation/infection (for example, fever with pelvic/perineal pain, significant urinary symptoms, or systemic unwellness), treatment may be different and sometimes longer. This is another reason self-treating or delaying assessment can backfire.

If it’s STI-related urethritis instead

If testing suggests an STI cause, treatment is different again and may also include partner-related steps. That’s why the “UTI vs STI” distinction and testing is so important for men.

When it’s serious (and when to seek urgent care)

A straightforward bladder infection is uncomfortable, but it becomes more urgent when there are signs the infection is affecting the kidneys, causing significant dehydration, or you’re unable to pass urine.

Seek urgent medical care if you have:

• Fever and chills
• Back/flank pain (pain under the ribs on either side of your spine)
• Nausea/vomiting
• Severe weakness, confusion, fainting, or signs of dehydration
• Difficulty passing urine (urinary retention)
• Heavy or persistent blood in urine

These symptoms can suggest kidney involvement or a complicated infection and should not be managed with “wait and see.”

Book a GP/telehealth review soon if:

• Symptoms persist beyond 24–48 hours without improvement
• Symptoms keep returning
• You have underlying risks like diabetes, kidney stones, or prostate symptoms
• You’re unsure whether symptoms are UTI vs STI

How men can reduce UTI risk (simple prevention)

Not every UTI is preventable, but many men can reduce risk by addressing the most common drivers: hydration, bladder emptying, and avoiding triggers.

Daily habits that help

• Hydrate consistently (steady water intake supports regular flushing)
• Don’t hold urine for long periods
• Urinate after sex if you’re prone to post-sex urinary symptoms
• Avoid dehydration-heavy habits during illness or travel (alcohol excess, long gaps between fluids)

If prostate symptoms are present, address them

If you have slow stream, straining, or frequent nighttime urination, it may signal incomplete emptying. Managing these issues can reduce recurrence risk.

If UTIs are recurrent, don’t self-manage indefinitely

Recurrent UTIs in men are a reason to get evaluated for underlying causes (prostate, stones, obstruction). Treating each infection without addressing the driver can lead to repeat episodes.

FAQs about UTIs in Men

1) How do you tell if a male has a UTI?

Common signs include burning when urinating, urgency/frequency, lower abdominal discomfort, and sometimes cloudy or bloody urine. If there’s fever, chills, back/flank pain, or vomiting, it may be more serious (kidney involvement) and should be assessed promptly.

2) What is the most common reason a man gets a UTI?

In many adult men, a key driver is incomplete bladder emptying, often linked to prostate enlargement with age. In younger men, “UTI-like” symptoms are sometimes due to STI-related urethritis, which is why testing matters.

3) What is mistaken for a UTI in a man?

Common look-alikes include STI-related urethritis, prostatitis, dehydration/irritation, and sometimes kidney stones. That’s why clinicians often recommend urine testing (and STI testing if relevant) rather than guessing.

4) How serious can UTI be in men?

Many cases are treatable, but UTIs in men are taken more seriously because they’re less common and can be linked to underlying issues (prostate, stones, obstruction). It’s more urgent if there are red flags like fever, flank pain, vomiting, confusion, or urinary retention.

5) How long do UTIs in men last?

With appropriate treatment, many people feel improvement within 24–48 hours, but full recovery depends on the cause and severity. If symptoms persist, worsen, or keep returning, it needs reassessment rather than repeated self-treatment.

6) What are the red flags for UTI in men?

Red flags include fever/chills, back or flank pain, nausea/vomiting, severe weakness/confusion, heavy blood in urine, or inability to pass urine (retention). These require prompt medical review.

7) How to clear a UTI in men?

A confirmed bacterial UTI is usually cleared with clinician-prescribed antibiotics based on urine testing/culture when appropriate, plus hydration and rest. If symptoms are due to STI-related urethritis or prostatitis, treatment differs so testing first is important.

8) How do you test a guy for a UTI?

Testing usually starts with a urine dipstick/urinalysis and often a urine culture to identify bacteria and guide treatment. If STI exposure is possible, clinicians may add STI testing as well.

9) What is the first stage of UTI?

Early on, symptoms are usually bladder/urethra-focused: mild burning, urgency, and frequency. If infection spreads upward, symptoms can escalate to fever, flank pain, and vomiting so early assessment is helpful if symptoms worsen.

Conclusion

Yes, men can get UTIs but because they’re less common in men, urinary symptoms should be assessed properly to rule out STIs, prostate issues, stones, or obstruction. If symptoms are mild and improving, that’s reassuring. But if you have red flags like fever, flank pain, vomiting, heavy blood in urine, or trouble passing urine, seek medical care promptly. Early testing and the right treatment plan usually leads to faster recovery and helps prevent recurrence.
