Quick answer
What is Hydrocele?
A hydrocele is a collection of fluid in the sac that surrounds a testicle, causing a soft, usually painless swelling on one or both sides of the scrotum. It is common in newborn babies, where it often clears by itself in the first year, and can also develop in adults, sometimes after inflammation, injury or with no clear cause.
- How it is treated: Many hydroceles, especially small and painless ones, need no treatment and can simply be monitored — and in babies most resolve on their own.
- Self-care: No specific lifestyle measures prevent a hydrocele.
- When to seek help: See a GP for any new scrotal swelling so the cause can be confirmed.
What it is
A hydrocele is a collection of fluid in the sac that surrounds a testicle, causing a soft, usually painless swelling on one or both sides of the scrotum. It is common in newborn babies, where it often clears by itself in the first year, and can also develop in adults, sometimes after inflammation, injury or with no clear cause. Hydroceles are generally harmless, but a new scrotal swelling should always be examined to be sure of the cause, as it is important to distinguish it from other conditions. An ultrasound may be used if there is any doubt.
How it is treated
Many hydroceles, especially small and painless ones, need no treatment and can simply be monitored — and in babies most resolve on their own. When a hydrocele is large, uncomfortable or causing concern, it can be treated by a small operation to remove or repair the sac, or sometimes by draining the fluid. The right approach depends on age, size, symptoms and the underlying cause, and is decided with a doctor. Any new or changing scrotal swelling is assessed first to confirm it is a hydrocele.

Beyond medication
Lifestyle and self-care
No specific lifestyle measures prevent a hydrocele. The key point is to have any new scrotal swelling examined so the cause is confirmed and reassurance or treatment given.
When to get help
When to see a doctor
See a GP for any new scrotal swelling so the cause can be confirmed. Seek urgent care for sudden severe testicular pain, redness, or a swelling that appears suddenly with pain.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
Answers
Hydrocele: frequently asked questions
Is a hydrocele serious?
Usually not — it is a generally harmless build-up of fluid. However, any new scrotal swelling should be examined to confirm the cause and rule out other conditions.
Do hydroceles go away on their own?
In babies they often clear by themselves in the first year. In adults they may persist; treatment is offered if they are large, uncomfortable or causing concern.
