What does orchitis mean?
Orchitis is the medical term for inflammation of a testicle. The condition can produce pain, swelling, and tenderness and may affect either one testicle or both. Orchitis can be associated with several infections, notably mumps, as well as other causes that require medical assessment. The word comes from Greek orchis, meaning “testicle,” combined with the suffix -itis, meaning “inflammation.” In general use, the formal expression is most common in medical discussions, diagnoses, and health information, while speakers usually describe it as testicular or testicle inflammation. The distinction from epididymitis is important because the two conditions affect adjacent parts of the male reproductive system and may have different causes and treatments.
