Hydrocele

A hydrocele is a sac filled with fluid that forms around a testicle. Hydroceles are most common in babies.

Nearly 10 percent of males are born with a hydrocele. However, they can affect males of any age.

Hydroceles generally don’t pose any threat to the testicles. They’re usually painless and disappear without treatment. However, if you have scrotal swelling, see your doctor to rule out other causes that are more harmful such as testicular cancer.

A hydrocele (HI-droe-seel) is a type of swelling in the scrotum that occurs when fluid collects in the thin sheath surrounding a testicle. Hydrocele is common in newborns and usually disappears without treatment by age 1. Older boys and adult men can develop a hydrocele due to inflammation or injury within the scrotum.

 A hydrocele usually isn’t painful or harmful and might not need any treatment. But if you have scrotal swelling, see your doctor to rule out other causes.
