What is a Hydrocele?
A hydrocele is a condition in which fluid collects around a testicle, causing painless swelling of the scrotum. The fluid builds up in a thin sac that surrounds the testicle.
Hydroceles are common in newborn baby boys and usually disappear on their own within the first year of life. In adult men, hydroceles typically develop due to inflammation, infection, or injury in the scrotum. While most hydroceles are harmless, large or long-standing hydroceles can cause discomfort, heaviness, and cosmetic concerns, and may need treatment.
Types of Hydrocele
Congenital (communicating) hydrocele: Present at birth, caused by failure of processus vaginalis to close, may fluctuate in size, fluid can flow between abdomen and scrotum
Acquired (non-communicating) hydrocele: Develops later in life, closed sac with trapped fluid, usually results from injury or infection
Symptoms of Hydrocele
Painless swelling on one or both sides of the scrotum
Feeling of heaviness or dragging in the scrotum
Swelling that increases during the day or with activity
Discomfort due to the size or weight of swelling
Scrotum may glow when light is shone through it (transillumination)
Usually no pain unless very large or infected
In babies, swelling may come and go

When to See a Doctor
Seek immediate medical care if you experience:
Sudden scrotal pain or rapid swelling
Fever with scrotal swelling
Nausea or vomiting with testicular pain
Schedule a doctor’s visit if:
You notice any scrotal swelling, even if painless
Swelling continues to increase
Heaviness or discomfort affects daily activities
You are concerned about changes in the scrotum or testicles
Doctors usually confirm hydrocele with physical examination and ultrasound, which helps rule out serious conditions such as testicular tumors or hernias.
