1 large 1 small testicle

Hi there! Men who've had inflammation of a testicle due to mumps or another cause on one side will be left with one small testicle. But if one testicle is normal and the other is larger, something else is responsible for the difference. Most often, it's a hydrocele; a benign collection of fluid around a normal testicle. A simple test called transillumination can tell doctors when fluid is present, since a bright light will pass though fluid but not a solid mass. Acute infections can cause a testicle to enlarge, these conditions are very painful and the swollen structures are red, warm and tender, do you suffer from those symptoms? The most severe possibility is testicular cancer, which typically produces a hard, non-tender lump or mass. Fortunately, the disease is highly curable. You should check your testicles in the nearest hospital, just in case. Better safe than sorry.
