What is a testicular hydrocele?
A hydrocele is an accumulation of serous fluid in the tunica vaginalis, the membrane that covers the testicle. This accumulation causes painless swelling or enlargement of the scrotum. It is a common condition in newborns, but it can also affect men of any age as a result of injury or inflammation.

Communicating hydrocele
This type is more common in babies. It occurs when the processus vaginalis doesn't close completely. This allows peritoneal fluid to flow into the scrotum and accumulate. The main characteristic is that the size of the hydrocele can vary throughout the day and usually decreases when lying down.
Simple hydrocele
In this case, the processus vaginalis is closed, but the body is unable to reabsorb the fluid that remains trapped around the testicle. It is common in adults, and the testicle's size usually remains stable. Often, no clear cause is identified, or it may be secondary to inflammation, infection, or trauma.
Causes
The causes of hydrocele vary depending on age:
- In newborns: It is a normal condition due to incomplete closure of the processus vaginalis. It usually resolves spontaneously during the first year of life.
- In adults:
- Inflammation or infection in the epididymis or testicle.
- Trauma, or a direct blow to the scrotum.
- Complication of a surgery, such as inguinal hernia or varicocele surgery.
- Sexually transmitted infections.
- Testicular cancer or Testicular cancerIn rare cases, a hydrocele can be a sign of an underlying testicular tumor.
Characteristic symptoms and signs
- Painless swelling on one or both sides of the scrotum.
- A feeling of heaviness or discomfort in the lower abdomen or scrotum, especially with increased size.
- The skin of the scrotum does not redden or become painful to the touch unless there is an underlying infection.
- The size may increase throughout the day or with physical exertion in communicating hydroceles.
- Upon palpation, the mass is soft and cannot be reduced or pushed into the abdomen.
Diagnosis and medical tests
- Physical exploration: The doctor palpates the scrotum, and transillumination is used, by applying a bright light behind the scrotum, to confirm that the contents are clear fluid.
- Scrotal ultrasound: This imaging test is used to confirm the diagnosis, rule out other pathologies, and evaluate the condition of the testicles and epididymis.
Differential clinical diagnoses
It is important to differentiate hydrocele from other conditions that also cause scrotal swelling.
Testicular hydrocele and varicocele
A varicocele is a dilation of the veins, not a fluid buildup. It feels like a bag of worms and is more prominent, while a hydrocele is a uniform, fluid-filled swelling.

Testicular hydrocele and hernia
A hernia occurs when abdominal contents protrude into the scrotum. Unlike a hydrocele, a hernia is usually reducible and can cause digestive symptoms if it becomes strangulated.
Testicular hydrocele and testicular torsion
Testicular torsion (read more about the Testicular torsion causesA traumatic encephalopathy (TE) is a medical emergency that causes acute and unbearable pain, whereas a hydrocele is typically painless or causes only mild discomfort.
Testicular hydrocele and testicular cancer
Testicular cancer usually presents as a hard, irregular lump within the testicle itself. A hydrocele is a fluid-filled sac around the testicle, which can sometimes mask an underlying tumor, making ultrasound crucial.
What treatment is available for hydrocele?
Pharmacotherapy
There are no medications to eliminate a hydrocele itself. However, antibiotics or anti-inflammatories may be prescribed to treat the underlying cause.
Needle aspiration or drainage
A needle is inserted into the scrotum to drain the fluid. This procedure is simple, but it has a high recurrence rate and carries risks of infection or bleeding. It is not usually a permanent solution.
Hydrocelectomy
This is the definitive surgery for treating hydrocele. A small incision is made in the scrotum or groin to drain the fluid, and the tunica vaginalis is removed or folded to prevent the fluid from accumulating again.
Is the treatment the same for adults and children?
No. In most infants, a hydrocele resolves spontaneously during the first year of life. Surgery is only considered if it persists, grows significantly, or is complicated by a hernia. In adults, surgery is the treatment of choice when it causes discomfort or is of a concerning size.
How to eliminate a hydrocele without surgery?
For small, asymptomatic hydroceles, conservative measures can be considered, but it is crucial to understand that there are no proven non-surgical methods to permanently remove a hydrocele.
Observation and controlled waiting
If the hydrocele is small and does not cause pain, the most sensible option is simply to monitor it with regular medical checkups.
Home or natural remedies
Some sources suggest using anti-inflammatory infusions or applying cold compresses to relieve discomfort. However, these methods do not eliminate the accumulated fluid, and their effectiveness is not scientifically proven.
Use of a sports jockstrap
Wearing a jockstrap or supportive underwear can help relieve the feeling of heaviness and discomfort, especially during physical activity, by providing better support to the enlarged scrotum.

What are the risks and consequences of this condition?
Inconvenience and practical problems
A large hydrocele can be uncomfortable, affect mobility, cause difficulties in dressing or having sex, and generate aesthetic complexes.
Complications from infection or strangulated hernia
If the hydrocele is communicating, there is a risk that it will develop into an inguinal hernia or that an associated hernia will become strangulated, which constitutes a surgical emergency.
Post-surgical complications (if surgery is performed)
Although rare, surgery can carry risks such as infection, bleeding, hematoma, damage to nearby structures, or recurrence of the hydrocele.
Does testicular hydrocele affect fertility?
Generally, no. A hydrocele itself does not affect sperm production or testicular hormone function. However, if the hydrocele is secondary to an underlying condition that can impact fertility, then the underlying condition could affect it. Surgery to correct a hydrocele does not usually have a negative impact on fertility.
Prevention and home care
- Injury protection. Wear protective equipment during contact sports.
- Practice safe sex to reduce the risk of sexually transmitted infections that can lead to epididymitis.
- See a doctor if you notice any signs of infection or inflammation in your genitals.
- Regular testicular self-exams to detect any abnormal changes early.
- For hydroceles that have already been diagnosed and are under observation, wear supportive underwear and avoid activities that put excessive pressure on the area.
Frequently Asked Questions (FAQs)
What infections cause hydrocele?
Infections such as epididymitis, orchitis, mumps, and sexually transmitted infections can cause an inflammatory reaction that leads to a secondary hydrocele.
When should a hydrocele be operated on in adults?
Surgery is recommended when the hydrocele is large, causes significant pain or discomfort, interferes with daily activities, has a doubtful diagnosis, or grows rapidly.
How much does a testicular hydrocele operation cost?
The cost varies greatly depending on the country, clinic, surgeon, and healthcare system. It can range from a few hundred to several thousand euros. A specific quote is required.
What happens if a hydrocele is not operated on?
If it's small and asymptomatic, it's unlikely to cause any problems. However, if it's large and left untreated, it can continue to grow, causing further discomfort, and in very rare cases, putting pressure on the testicle that could affect its blood supply.
How long does it take for a hydrocele to go down?
After surgery, postoperative swelling can take several weeks or even a few months to disappear completely.
Can a hydrocele be dangerous?
In the vast majority of cases, no. It is a benign condition. The danger lies in failing to correctly diagnose the underlying cause or in the complications of a large, untreated communicating hydrocele.

Conclusion
A hydrocele can be alarming due to the swelling it causes, but it is generally a benign condition. An accurate diagnosis by a urologist is essential to differentiate it from other, more serious conditions. Treatment ranges from simple observation in asymptomatic cases to surgery when it causes discomfort or complications; surgery is the only definitive method for its removal. Talk to your doctor without fear and improve your quality of life.
