Accumulation of fluid formed around a testicle is called a hydrocele. It is a kind of swelling in the scrotum which occurs when the fluid collects in the thin sheath around the testicle. It occurs mainly on one side of the testicle but it can occur over both testicles as well. It is commonly found in babies but can also develop in adult boys and men. Hydrocele can affect any male irrespective of his age. Hydrocele in babies does not require any treatment as it is painless and causes no harm as such. It vanishes on its own till the baby turns one. Even if it doesn’t disappear, it is not a worrisome matter as it does not hurt any baby. However, one must see a doctor and discuss the problem with him. The risk of a hydrocele is more in the babies who are born prematurely.
Though it is not threatening, a scrotum swelling is a serious issue. In order to avoid serious medical conditions such as testicular cancer due to swelling, one must consult a doctor. Hydrocele and varicocele are two different conditions. The abnormal enlargement of veins (pampiniform plexus) inside the scrotum is known as varicocele.
