If you are a male and experiencing pain in the scrotum or testicle, then it might be attributed to epididymitis, orchitis or a combination of the two. The information below will give you a head start in learning more about these conditions and aid in you in your discussions with a urologist.
What are epididymitis, orchitis and epididymo-orchitis?
Epididymitis is inflammation of the epididymis—the coiled tube that collects sperm from the testicle and passes it on to the vas deferens. There are two forms of this disease, acute and chronic. Acute epididymitis comes on suddenly with severe symptoms and subsides with treatment. Chronic epididymitis is a long-standing condition, usually of gradual onset, for which the symptoms can be improved with treatment but may not completely be eradicated. Most cases of epididymitis occur in adults.
Orchitis is inflammation of the testicle. It is almost always comes on suddenly and subsides with treatment. Chronic orchitis is not well-defined, and instead is considered to be one of the many conditions related to chronic testicular pain (orchalgia).
Epididymo-orchitis is the sudden inflammation of both the epididymis and the testicle.
