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.
