Other namesOrchiditis

Orchitis is inflammation of the testicles.[1] It can also involve swelling, pains and frequent infection, particularly of the epididymis, as in epididymitis. The term is from the Ancient Greek ὄρχις meaning "testicle"; same root as orchid.

Signs and symptoms[edit]

Symptoms of orchitis are similar to those of testicular torsion. These can include:[citation needed]


Orchitis can be related to epididymitis infection that has spread to the testicles (then called "epididymo-orchitis"), sometimes caused by the sexually transmitted infections chlamydia and gonorrhea. It has also been reported in cases of males infected with brucellosis.[2] Orchitis can also be seen during active mumps, particularly in adolescent boys.[citation needed]

Ischemic orchitis may result from damage to the blood vessels of the spermatic cord during inguinal herniorrhaphy, and may in the worst event lead to testicular atrophy.[3]

  • Urine – Cultural & Sensitivity test
  • Ultrasound scanning


In most cases where orchitis is caused by epididymitis, treatment is an oral antibiotic such as cefalexin or ciprofloxacin until infection clears up. In both causes non-steroidal anti-inflammatory drugs such as naproxen or ibuprofen are recommended to relieve pain. Sometimes stronger pain medications in the opiate category are called for and are frequently prescribed by experienced emergency department physicians.[citation needed]

Other animals[edit]

Orchitis is not rare in bulls and rams.[citation needed] It has also been described in roosters.[4]
