Chlamydial urethritis in men is an infection of the urethra caused by the sexually transmitted disease (STD) chlamydia. The urethra carries urine from the bladder, through the penis, and to the outside of the body.
This condition often causes swelling and inflammation of the urethra, accompanied by penile discharge. But as with many STDs, men often don’t show symptoms. An infected person and all recent and current sexual partners must receive treatment for STDs to prevent reinfection.
The bacteria Chlamydia trachomatis causes chlamydial urethritis. It’s spread through oral, anal, and vaginal sex. Both men and women can develop this common type of infection.
According to the Centers for Disease Control and Prevention (CDC), chlamydia is the most prevalent STD in the United States. Many of these cases are in adolescents and young adults.
People who have unprotected sex with multiple partners are more likely to contract chlamydial urethritis than those who practice safe sex and are in a monogamous relationship. Sexually active people before the age of 25 are also more likely to contract STDs in general, including chlamydia, according to the Mayo Clinic.
Men with chlamydial urethritis may not show symptoms at all, or they may only start to show symptoms several weeks after exposure to the bacteria. Symptoms of chlamydia and the related inflammation of the urethra usually occur between one and three weeks after exposure to the bacteria.
The signs of infection include:
The urethra becomes inflamed during infection, making urinating more difficult. Discomfort in the penis is generally limited to the tip, where the urethra ends.
Symptoms of chlamydial urethritis in men can mimic the symptoms of gonorrhea. Gonorrhea and chlamydia infections often occur at the same time, and anyone infected may require treatment for both STDs.
Your doctor will perform a series of lab tests to diagnose chlamydial urethritis. You’ll be asked to give a urine sample, which will be tested for the presence of the chlamydia organism.
You may also need a urethral discharge culture, or swab test, to rule out gonorrhea. Gonorrhea symptoms often look like the symptoms of chlamydia. It’s possible to have both at the same time.
A technician will swab the head of your penis with alcohol or another sterile agent. Next, the technician or your doctor will insert a cotton swab into your urethra at the tip of your penis. The discharge or fluids collected will be analyzed to determine the cause of your infection.
If you’re diagnosed with chlamydial urethritis, you and any of your sexual partners must be treated with antibiotics. It’s important for your partners to receive treatment, even if they don’t show signs of an infection.
This helps prevent reinfection. Without proper treatment, sexual partners may continue to pass the bacteria back and forth.
Several antibiotics can eliminate chlamydial urethritis, including:
In most cases, your doctor will prescribe antibiotics for 5 to 10 days. But the CDC notes that a higher dose of 1 gram of azithromycin taken once may also be an effective treatment.
Most infections will resolve within a week or two. It’s important that you abstain from sexual activity for at least seven days after completing a course of antibiotics to prevent reinfection.
It’s important to seek treatment for STDs as soon as symptoms occur. Untreated infections can spread and lead to more serious health complications in men, including:
Men often don’t show signs of infection right away. Regular screenings for STDs can diagnose STDs even if no symptoms are present. This is especially important when changing partners or if you have multiple partners.
Regular screenings for STDs, including HIV, are important for anyone who’s sexually active, and especially for those with multiple partners.
