UTI Symptoms in Men: How Infections Affect Performance & Next Steps

Urinary tract infections (UTIs) are often thought of as a women's health issue, but men can get them too—especially as they age. When a UTI happens, it can cause uncomfortable urinary symptoms and, in some cases, affect sexual performance.

A common question many men ask is: Can a urinary tract infection cause ED (erectile dysfunction)?

The short answer is yes, it can—but usually temporarily. Let's break down why that happens, what symptoms to watch for, and what to do next.

What Is a UTI in Men?

A urinary tract infection occurs when bacteria enter the urinary system. This includes:

• The urethra (tube that carries urine out)
• The bladder
• The prostate
• In more serious cases, the kidneys

In men, UTIs are less common than in women but can be more complicated when they occur. They are sometimes linked to:

• Enlarged prostate (BPH)
• Kidney stones
• Urinary retention (not fully emptying the bladder)
• Catheter use
• Diabetes
• A weakened immune system

When infection or inflammation affects nearby structures like the prostate, sexual function can also be impacted.

Common UTI Symptoms in Men

UTI symptoms in men can range from mild to severe. Common signs include:

• Burning or pain during urination
• Frequent urge to urinate
• Feeling like you can't fully empty your bladder
• Cloudy or strong-smelling urine
• Blood in the urine
• Pelvic or lower abdominal discomfort
• Fever or chills (in more serious cases)

If the prostate becomes infected (a condition called prostatitis), symptoms may also include:

• Pain between the scrotum and anus
• Pain during ejaculation
• Erectile difficulties
• Flu-like symptoms

If you have fever, back pain, nausea, or severe weakness, seek medical care right away, as this could signal a more serious kidney infection.

Can a Urinary Tract Infection Cause ED?

Yes, a urinary tract infection can cause ED—but typically in a temporary and treatable way.

Here's how it happens:

1. Inflammation Affects Blood Flow

Erections depend on healthy blood flow. When there's infection and inflammation in the urinary tract or prostate, nearby tissues can swell. This inflammation can:

• Interfere with nerve signaling
• Reduce blood flow efficiency
• Cause discomfort that disrupts arousal

2. Prostatitis and Erectile Dysfunction

When a UTI spreads to the prostate, it can trigger prostatitis. Research shows that prostatitis is linked with:

• Erectile dysfunction
• Painful ejaculation
• Reduced libido

The prostate plays a key role in sexual function. Inflammation there can directly interfere with erection quality.

3. Pain and Psychological Impact

Pain changes how your body responds to sexual stimulation. If urination or ejaculation hurts, your brain may subconsciously reduce sexual response.

Temporary ED during a UTI is often caused by:

• Physical discomfort
• Anxiety about pain
• Fatigue from fighting infection
• Stress

The good news: once the infection is treated, erectile function often improves.

How Common Is ED During a UTI?

ED during a simple bladder infection is not extremely common, but it is more likely when:

• The prostate is involved
• Symptoms are severe
• The infection is untreated
• The man already has mild ED

Men over 50 are more likely to experience both UTIs and erectile dysfunction due to overlapping risk factors like prostate enlargement and vascular changes.

How Long Does ED Last After a UTI?

In most cases:

• ED caused by a UTI improves within days to weeks after treatment
• Antibiotics clear the infection
• Inflammation subsides
• Sexual function gradually returns

However, if erectile issues continue after the infection has cleared, other factors may be involved, such as:

• Diabetes
• Cardiovascular disease
• Hormonal imbalances
• Chronic prostatitis
• Anxiety or stress

Persistent ED should always be evaluated by a doctor.

Treatment for UTI in Men

Treatment usually involves prescription antibiotics. It's important to:

• Take the full course exactly as prescribed
• Avoid stopping early, even if symptoms improve
• Drink plenty of water
• Avoid alcohol if advised

If prostatitis is present, treatment may last longer (sometimes several weeks).

In some cases, doctors may also:

• Check prostate health
• Order urine or blood tests
• Perform imaging if infections keep returning

Prompt treatment reduces the risk of complications and improves sexual recovery.

When to See a Doctor

Men should always take UTI symptoms seriously. Unlike women, UTIs in men are often considered "complicated" infections.

Speak to a doctor promptly if you notice:

• Burning with urination
• Fever
• Pelvic pain
• Erectile dysfunction that appears suddenly
• Blood in your urine
• Back or flank pain

Seek urgent care if you develop:

• High fever
• Severe back pain
• Vomiting
• Confusion
• Weakness

These could signal a kidney infection or systemic infection, which can be serious.

---

Can UTIs Cause Long-Term Erectile Dysfunction?

In most healthy men, no—a UTI does not cause permanent ED.

However, complications can increase risk if:

• The infection spreads to the prostate and becomes chronic
• There is delayed treatment
• There is repeated infection
• There are underlying vascular conditions

Chronic prostatitis, in particular, can contribute to ongoing sexual performance issues.

The key factor is early treatment.

Reducing Your Risk of UTIs and ED

While not all infections are preventable, you can lower your risk by:

• Staying well hydrated
• Urinating regularly (don't hold it in for long periods)
• Managing diabetes carefully
• Practicing safe sex
• Treating prostate enlargement if present
• Maintaining heart health (blood pressure, cholesterol, weight)

Because erections rely heavily on blood flow, anything that supports cardiovascular health also supports erectile function.

---

The Bottom Line: Can a Urinary Tract Infection Cause ED?

Yes, a urinary tract infection can cause ED—but usually temporarily.

Most cases improve once the infection and inflammation are treated. The connection typically happens due to:

• Prostate inflammation
• Pain
• Disrupted blood flow
• Stress on the body

If erectile dysfunction continues after the infection clears, it may signal another underlying issue that deserves evaluation.

Final Thoughts

UTIs in men are treatable, and temporary sexual performance changes during infection are not uncommon. The important thing is not to ignore symptoms.

If you're experiencing urinary symptoms, erectile issues, or both:

• Don't self-diagnose
• Don't ignore persistent symptoms
• Don't feel embarrassed—this is common and treatable

Before your doctor's appointment, you can check your symptoms using Ubie's free AI-powered symptom checker tool to help organize your concerns and get personalized insights about what might be happening.

Most importantly, speak to a doctor about any symptoms that could be serious, especially fever, blood in urine, severe pain, or ongoing erectile dysfunction. Early treatment protects both your urinary health and your sexual health.

Taking action early makes recovery smoother—and helps you get back to feeling like yourself again.
