n. inflammation of the testis. This causes pain, redness, and swelling of the scrotum, and may be associated with inflammation of the epididymis (epididymo-orchitis). The condition may affect one or both testes; it is usually caused by infection spreading down the vas deferens but can develop in mumps. Mumps orchitis affecting both testes may result in sterility. Treatment of epididymo-orchitis is by local support and by administration of analgesics and antibiotics; mumps orchitis often responds to corticosteroids.
