Enlarged testicles can result from the swelling of soft tissues, a lump or a cyst inside the testicle, but injury is the most common cause, states Healthgrades. This condition may occur in one or both testicles and may include pain, swelling or fever. In some cases, an enlarged testicle may be a sign of a life-threatening condition, such as testicular torsion, and requires emergency medical care.

Treatment for an enlarged testicle includes a physical exam, tests such as a urinalysis and ultrasound, and antibiotics when the cause is a bacterial infection. Treatment for pain and swelling reduction may include applying hot or cold packs, elevating the scrotum in snug briefs or an athletic supporter, and taking acetaminophen, ibuprofen or naproxen, although ibuprofen and other NSAIDs are not recommended if the patient has heart failure or kidney failure, according to WebMD.

An enlarged testicle may be due to serious diseases and failure to seek medical treatment may result in complications such as infarction of the testicular tissue, infertility, scrotal abscess, spread of cancer, spread of infection and testicle removal, states Healthgrades.
