Epididymitis

DEFINITION

Epididymitis is an inflammation of the coiled tube (epididymis) at the back of the testicle that stores and carries sperm. Males of any age can get epididymitis.

Epididymitis is most often caused by a bacterial infection, including sexually transmitted infections (STIs), such as gonorrhea or chlamydia. Sometimes, a testicle also may become inflamed — a condition called epididymo-orchitis.

CAUSES

Causes of epididymitis include:

  • STIs. Gonorrhea and chlamydia are the most common causes of epididymitis in young, sexually active men.
  • Other infections. For boys and men who aren’t sexually active, epididymitis can be caused by a nonsexually transmitted bacterial infection. In boys and men with urinary tract or prostate infections, bacteria might spread from the infected site to the epididymis.
  • Amiodarone (Pacerone). This heart medication can cause inflammation of the epididymis.
  • Urine in the epididymis (chemical epididymitis). This condition occurs when urine flows backward into the epididymis, possibly because of heavy lifting or straining.
  • Trauma. A groin injury can cause epididymitis.
  • Tuberculosis. Rarely, epididymitis can be caused by tuberculosis infection.

SYMPTOMS

Signs and symptoms of epididymitis might include:

  • A swollen, red or warm scrotum
  • Testicle pain and tenderness, usually on one side
  • Painful urination or an urgent or frequent need to urinate
  • Discharge from the penis
  • Painful intercourse or ejaculation
  • A lump on the testicle
  • Enlarged lymph nodes in the groin
  • Pain or discomfort in the lower abdomen or pelvic area
  • Blood in the semen
  • Less commonly, fever

Chronic epididymitis

Epididymitis that lasts longer than six weeks or that recurs is considered chronic. Symptoms of chronic epididymitis might come on gradually. Sometimes the cause of chronic epididymitis is not identified.

When to see a doctor

Never ignore scrotal pain or swelling. Scrotal pain can be caused by a number of conditions, and some of them require immediate treatment to avoid permanent damage.

If scrotal pain is severe, seek emergency treatment. Also see a doctor if you have discharge from your penis or pain when you urinate.
