Chlamydia Symptoms in Men: Key Signs and Prevalence
Chlamydia is a common sexually transmitted infection (STI) that often affects men without causing noticeable symptoms. When symptoms do occur, they can include discharge from the penis, a burning sensation during urination, and pain or swelling in one or both testicles 17. These symptoms are most commonly linked to urethritis, which is inflammation of the urethra 3489.
Asymptomatic Chlamydia Infections in Men
A significant number of men with chlamydia do not experience any symptoms. Studies show that up to 50% of men with chlamydia may be asymptomatic, meaning they do not notice any signs of infection 2789. This lack of symptoms is important because it allows the infection to go undetected and untreated, increasing the risk of complications and transmission to others 279.
Common Symptomatic Presentations: Urethritis and Testicular Pain
When chlamydia does cause symptoms in men, the most frequent issues are:
- Discharge from the penis
- Burning or pain during urination
- Pain and swelling in one or both testicles 1789
Chlamydia is a leading cause of nongonococcal urethritis (NGU), which is urethral inflammation not caused by gonorrhea. Men with NGU often report the above symptoms, and chlamydia is a common underlying cause 3489.
Chlamydia at Other Anatomical Sites: Rectal and Pharyngeal Infections
Chlamydia can also infect the rectum and throat, especially in men who have sex with men (MSM). Rectal chlamydia may cause symptoms like rectal pain, discharge, or bleeding, but it is often asymptomatic. Pharyngeal (throat) chlamydia is usually without symptoms, though a small number of men may report throat discomfort 256.
Importance of Screening and Early Detection
Because chlamydia in men is frequently asymptomatic, regular screening is recommended for those at risk, including sexually active young men and MSM. Early detection and treatment with antibiotics are important to prevent complications and reduce the spread of infection 1279.
Conclusion
Chlamydia in men most often presents with no symptoms, but when symptoms do occur, they typically include penile discharge, burning during urination, and testicular pain or swelling. Asymptomatic infections are common, making regular screening essential for early detection and prevention of complications. Chlamydia can also infect the rectum and throat, often without symptoms, especially in MSM. Early treatment is effective and helps prevent long-term health issues and further transmission.
