Epididymitis is inflammation and infection of the long, tightly coiled tube that lies behind each testicle and collects sperm (epididymis). Epididymitis can be caused by a urinary tract infection, a sexually transmitted disease, an enlarged prostate, or a urologic procedure.

Epididymitis usually starts suddenly. Symptoms can include pain, scrotal swelling, painful or frequent urination, and fever or chills.

Bacterial epididymitis is treated with antibiotics. Other treatments for epididymitis may include bed rest, ice packs, scrotal support with a jock strap, and pain medicine.

A person with symptoms of epididymitis should avoid sexual intercourse until he sees a doctor. This will reduce the risk of spreading a possible infection to his sex partner or partners. It is important for sex partners to be evaluated and treated for a possible infection.
