CAUSES OF URETHRITIS
Most episodes of urethritis are caused by infection by bacteria that enter the urethra from the skin around the urethra’s opening. Bacteria that commonly cause urethritis include:
- Gonococcus, which is sexually transmitted and causes gonorrhea.
- Chlamydia trachomatis, which is sexually transmitted and causes chlamydia.
- Bacteria in and around stool.
- The herpes simplex virus (HSV-1 and HSV-2) can also cause urethritis. Trichomonas is another cause of urethritis. It is a single-celled organism that is sexually transmitted.
Sexually transmitted infections like gonorrhea and chlamydia are usually confined to the urethra. But they may extend into women’s reproductive organs, causing pelvic inflammatory disease (PID).
In men, gonorrhea and chlamydia sometimes cause epididymitis, an infection of the epididymis, a tube on the outside of the testes. Both PID and epididymitis can lead to infertility.
