Common Symptoms

Discharge from the Penis

White, cloudy, or watery discharge from the tip of the penis. May be more noticeable in the morning.

Burning or Pain When Urinating

A burning or stinging sensation when you pee, also known as dysuria.

Testicular Pain or Swelling

Pain, tenderness, or swelling in one or both testicles (this may indicate epididymitis).

Itching or Irritation

Itching, burning, or irritation around the opening of the urethra at the tip of the penis.

Important: About 50% of men with chlamydia have no symptoms. If you've had unprotected sex, consider getting tested even without symptoms.

When to Get Tested

You should consider a chlamydia test if:

  • You have any of the symptoms listed above
  • You've had unprotected sex with a new partner
  • A sexual partner has tested positive for chlamydia
  • You have multiple sexual partners
  • You're under 25 and sexually active (routine screening recommended)
  • You haven't been tested in the last year

Complications if Left Untreated

Untreated chlamydia in men can lead to serious health issues, though these are preventable with early treatment:

  • Epididymitis (painful swelling of the tubes next to the testicles)
  • Reactive arthritis
  • Urethritis (inflammation of the urethra)
  • Increased risk of HIV transmission
  • Rarely, infertility

Good news: All these complications are preventable with early detection and treatment.
