Physical Examination

During a physical exam, the scrotum is usually found to be swollen but not tender. Often, the testicle cannot be felt because of the surrounding fluid. The size of the fluid-filled sack can sometimes be increased and decreased by pressure to the abdomen or the scrotum.
If the size of the fluid collection varies, it is more likely to be associated with an inguinal hernia.
Hydroceles can be easily demonstrated by shining a flashlight (transillumination) through the enlarged portion of the scrotum. If the scrotum is full of clear fluid, as in a hydrocele, the scrotum will light up.
