A hydrocele is a collection of fluid in the scrotum, the pouch that holds the testicles. It is not harmful to the testicles and does not cause discomfort.
- Hydroceles are sometimes present at birth or may develop later.
- They can occur on one or both sides of the scrotum.
- The fluid typically makes the scrotum look enlarged.
Hydroceles often go away on their own and no treatment is typically needed. If the hydrocele has not disappeared by the time your son turns 1 or becomes very large, or if your son has an open hydrocele, he may need a simple operation to remove the hydrocele.
