Definition of Epididymitis

Epididymitis: Inflammation of the epididymis. Epididymitis can be caused by sexually acquired bacteria, such as gonorrhea and chlamydia; or by bacteria that come from somewhere else, such as E. coli from the bowel. Sometimes no bacteria are found to be associated. Bacterial epididymitis is treated with antibiotics. If no bacterial cause is detected, medications to reduce inflammation are sometimes helpful.
