Because the exact cause is not known, prevention is hard. Preventing acute epididymitis may reduce the risk. Acute epididymitis is often a sexually transmitted disease, or STD. Using safer sex can help prevent STDs. However, some men get chronic epididymitis without having these risk factors.
Chronic epididymitis may cause chronic pain. However, it has no other serious long-term effects.
Chronic epididymitis is not contagious. It poses no risk to others.
