Definition

By Mayo Clinic staff

Epididymitis is an inflammation of the coiled tube (epididymis) at the back of the testicle that stores and carries sperm. Pain and swelling are the most common signs and symptoms. Males of any age can get epididymitis, but it's most common in men between the ages of 19 and 35.

Epididymitis is most often caused by a bacterial infection or by a sexually transmitted disease (STD) such as gonorrhea or chlamydia. In some cases, the testicle may also become inflamed — a condition called orchitis.
