Hydrocele

Reviewed by Dr Abhishek Kumar on 23 September 2026

A hydrocele is a build-up of clear fluid in the thin sac that normally surrounds a testicle, producing a soft, usually painless swelling on one or both sides of the scrotum. It can be present from birth, when it is common and usually closes on its own, or appear later in life, sometimes after an injury, an infection, or — rarely — alongside a testicular tumour that needs to be ruled out.

Book a private consultation

A hydrocele is diagnosed on examination and confirmed by shining a light through the swelling or, more reliably, with a scrotal ultrasound, which also checks the testicle underneath and distinguishes the fluid from a hernia or a solid lump^[1]. In a newborn boy, a hydrocele is often a leftover open channel from before birth and typically seals and drains away on its own within the first year or two of life; in an adult, a new one is treated as needing an explanation rather than left alone, because it can occasionally point to infection, a twisted testicle, or a tumour^[1]. The fluid itself sits inside a closed membrane, and whatever caused it, the swelling is a physical space that has filled up — a fact that shapes every option offered for it.

When to see a doctor

Seek care without delay if

Sudden, severe pain in the scrotum needs emergency care the same day, since it may signal testicular torsion rather than a straightforward hydrocele.
A scrotal swelling that rapidly increases in size, turns red or hot, or is accompanied by fever needs urgent assessment.
A hard lump felt within or alongside the swelling needs prompt in-person evaluation.
Nausea or vomiting alongside sudden scrotal pain needs emergency care.
A swelling that appears suddenly after an injury to the groin or scrotum needs same-day assessment.

Book a consultation when

A new painless scrotal swelling in an adult is worth a routine consultation rather than being left unassessed.
A swelling present since infancy that has not closed by around the first or second birthday is worth reviewing with a doctor.
A hydrocele that is growing slowly over weeks or months, without severe pain, is still worth booking an appointment for.
Discomfort, heaviness or a dragging sensation in the scrotum that is not severe is worth mentioning at a routine visit.

Some symptoms need prompt care: when to seek emergency or specialist care.

How each system of medicine approaches Hydrocele

System	Approach	Typical review period
Modern medicine	Assessment usually begins with examination and, when needed, ultrasound to confirm the hydrocele and check for other causes of scrotal swelling, such as a hernia, infection, or an underlying testicular abnormality^[1].	Hydrocelectomy is usually a day-case procedure with a return to normal activity over 1-2 weeks; aspiration is quicker to do in clinic, but a systematic review comparing the two found the fluid comes back more often after aspiration and sclerotherapy than after surgery^[2].	Supported by clinical evidence Diagnosis is based on clinical examination and, when needed, ultrasound. Treatment options include observation, hydrocelectomy, or aspiration with sclerotherapy depending on the patient's age, symptoms, cause, and clinical findings.

Modern medicine for Hydrocele

Definitive treatment empties and closes the space itself: a surgeon either removes or folds back the sac at open surgery, or a doctor draws off the fluid with a needle and instils a sclerosing agent to scar the space shut so fluid cannot reaccumulate there.

Watch or treat depends on the situation: many infant hydroceles resolve without treatment during early childhood, while a new hydrocele in an adult may require assessment to identify an underlying cause^[1].
Two ways to treat it: surgery removes or repairs the hydrocele sac, while aspiration with sclerotherapy avoids an operation but has a higher risk of recurrence and may require repeat treatment^[2].
Why medicines do not usually shrink it: a hydrocele is a collection of fluid around the testicle. There is no established oral medicine, herbal treatment, or homeopathic treatment that reliably removes the fluid or permanently closes the underlying space.

What is known and what remains uncertain

Known: a scrotal ultrasound reliably distinguishes a hydrocele from a hernia or a solid testicular lump.
Known: most hydroceles present at birth close and drain away on their own within the first year or two of life.
Known: a systematic review found the fluid returns more often after needle aspiration and sclerotherapy than after surgical removal of the sac.
Uncertain: no oral herbal or homeopathic remedy has been shown in trials to drain the fluid or close the membrane around it.

Questions to ask your doctor

Is this a straightforward hydrocele, or do we need an ultrasound to rule out a hernia or something else?
Given my age and how long I have had it, would you recommend watching, aspiration or surgery?
How does the chance of the fluid coming back differ between aspiration and surgery?
What should I expect during recovery after a hydrocelectomy?
Are there any risks specific to my case, such as effects on fertility?
What symptoms after the procedure would mean I need to come back urgently?

Frequently Asked Questions

Will a hydrocele go away without treatment?

In a newborn boy, usually yes — most close and drain away by themselves within the first year or two of life^[1]. In an adult, a hydrocele is less likely to disappear by itself and is usually assessed rather than simply watched.

How is a hydrocele different from a hernia?

Both can cause a scrotal or groin swelling, but a hydrocele is fluid inside a closed membrane around the testicle, while a hernia is bowel or fatty tissue pushed through the abdominal wall; examination and ultrasound tell them apart^[1].

Can Ayurveda or homeopathy shrink a hydrocele?

No remedy taken by mouth has been shown to drain the fluid or close the membrane around it, so this page offers only the modern-medicine route, and a consultation in any system leads to the same assessment.

Does aspiration avoid the need for surgery?

It avoids an operation on the day, but the fluid returns more often after aspiration and sclerotherapy than after surgical removal of the sac, according to a review comparing the two^[2].

Is a hydrocele dangerous?

A straightforward hydrocele is not dangerous by itself, but a new one in an adult is assessed to rule out a hernia, infection, or, rarely, a testicular tumour, so it is worth having it looked at rather than assumed^[1].
