A hydrocele is a fluid-filled sac surrounding the testicle within the scrotum, the sac that hangs below the penis. It typically occurs when fluid gathers in the tissue surrounding the testicle, leading to swelling and enlargement of the scrotum. Hydroceles can vary in size and are usually painless. While they may occur at any age, they are more commonly found in newborns and older men. In infants, hydroceles often resolve on their own within the first year of life without treatment. However, in adults, treatment may be necessary if the hydrocele causes discomfort or grows significantly in size. Treatment options include observation, draining the fluid, or surgical removal of the hydrocele sac.
