A hydrocele is fluid-filled sac within the scrotum of a male — essentially a backup of fluid around one or both testicles.[1] The condition is relatively common, with an estimated 5% of baby boys born with one. They can also develop in older children or adult men due to an infection or injury to the scrotum.[2] In most cases, hydroceles are not harmful and tend to go away on their own, without treatment, but scrotal swelling should always be evaluated by a healthcare provider to rule out other causes. Curing a persistent hydrocele typically requires surgery, although some home remedies may also help.
Draining a Hydrocele at Home
If your hydrocele is painless, take a warm bath with Epsom salt for 15 to 20 minutes with your legs spread. If it causes pain or other symptoms, talk to your doctor. A medical professional can drain the fluid in the scrotum with a needle or have the entire hydrocele surgically removed.
Steps
Try an Epsom salt bath. If you notice a painless swelling in your testicle(s)/scrotum, take a very warm bath with at least a few cups of Epsom salt added.[3] Relax in the tub for between 15 – 20 minutes with your legs slightly spread, so that the water engulfs your scrotum. The warmth of the water can stimulate the movement of body fluids (which may help unblock a blockage) and the salt can pull fluid out through your skin and reduce swelling. Epsom salt is also a rich source of magnesium, which helps to relax muscles/tendons and soothe any tenderness.- If there is pain associated with your hydrocele, then exposing your scrotum to warm water (or any source of heat) may create more inflammation and make your symptoms worse.
- Don't make the bath too hot (to prevent scalding) and don't sit in the tub for too long (to prevent dehydration).
Recognize the signs and symptoms. The first indication of a hydrocele is a painless swelling or enlargement of the scrotum, representing a collection of fluid around one or both testicles.[4] Babies rarely have complications from a hydrocele and the vast majority disappear before the age of 1 without treatment. In contrast, men with hydroceles may eventually experience discomfort as the scrotum swells and gets heavy. It can create difficulty sitting or walking/running in extreme cases.- Pain or discomfort from a hydrocele is generally correlated to its size — the bigger it gets, the more likely you are to feel it.[5]
- Hydroceles tend to be smaller in the morning (upon waking) and then get more swollen as the day progresses.[6] Straining may cause certain hydrocele's to increase in size.
- Babies born prematurely have a greater risk of having hydroceles.[7]
Did you know: There are 2 main types of hydrocele: communicating and noncommunicating. In a communicating hydrocele, fluid travels between the scrotum and the abdominal cavity, causing the hydrocele to fluctuate in size. In a noncommunicating hydrocele, the fluid comes from the tissues of the scrotum itself, so the amount of fluid tends to stay constant throughout the day.

Be patient with a hydrocele. In the vast majority of cases among baby boys, teenagers, and men, hydroceles go away on their own without any specific treatment.[8] The blockage or congestion near the testicle(s) resolves itself and the hydrocele drains and gets absorbed into the body. Thus, if you notice an enlarged scrotum and it's not painful or causing problems with urination or during sex, give it some time to resolve itself.[9]- For baby boys, hydroceles usually fade away on their own within 1 year of being born.
- For men, hydroceles often gradually disappear within 6 months, depending on the cause. Larger ones may take more time, but shouldn't go beyond 1 year without medical intervention.
- However, in children and adolescents, hydroceles can be caused by infection, trauma, testicular torsion, or tumor, so these conditions must be excluded by examination from a doctor.
- Hydroceles are similar to fluid-filled ganglions that form in tendon sheaths near joints and then gradually disappear.
Avoid trauma to the testes and STDs. The cause of hydroceles is unknown in baby boys, although it's thought to be a backup of fluid from poor circulation due to the baby's position in the womb. In older boys and men, however, the cause is usually related to trauma to the scrotum or an infection.[10] Trauma can occur from wrestling, martial arts, cycling, and various sexual activities. Infections in the testes/scrotum are often related to sexually transmitted diseases.[11] Therefore, protect your scrotum from trauma and practice safe sex.- If you play contact sports, always wear an athletic supporter with a plastic cup to protect your scrotum from injury.
- Always use a new condom when having sex in order to significantly reduce your risk of infection. STDs don't always infect the testicles, but it's not uncommon, either.
Know when to seek medical treatment. You should seek medical attention for your baby boy if his swollen scrotum doesn't disappear after a year, or it continues to get larger.[12] Men should see their doctor if a hydrocele persists for more than 6 months, or if it gets big enough to cause pain/discomfort or disfigurement.- A testicular infection is not the same as a hydrocele, but it can cause one secondarily. Testicular infections are very painful and should be treated because they increase your risk of infertility. Always seek medical treatment if you experience scrotal swelling and fever.
- It's also time to see your doctor if the hydrocele is affecting the way you run, walk, or sit.
- Hydroceles don't directly impact fertility.
See your doctor for an examination. If the hydrocele persists for longer than normal or it's causing pain and other symptoms, then see your family physician for an examination. Hydroceles are not serious, but your doctor will want to rule out other relatively serious conditions that can appear similar, such as: an inguinal hernia, varicocele, infection, benign tumor or testicular cancer.[13] Once a diagnosis of a hydrocele is made, your options are essentially all surgical. Medications are not effective.- Your doctor will start with a physical exam to check for tenderness or signs of a hernia. They may use diagnostic ultrasound, an MRI, or a CT scan to better visualize what's going on inside the scrotum.[14]
- Shining a bright light through the scrotum can reveal if the fluid is clear (indicating a hydrocele) or murky, which could be blood and/or pus.
- Blood and urine tests are helpful to rule out infections, such as epididymitis, the mumps, or various STDs.
Get the fluid removed. Once the hydrocele is diagnosed, the least invasive procedure is to have the fluid drained from the scrotum by a needle, which is called aspiration.[15] After a topical anesthetic is given, a needle is inserted into the scrotum to penetrate the hydrocele, then the clear fluid is removed. If the fluid is bloody and/or pus-filled, then that indicates an injury, infection, or perhaps cancer. This procedure is very quick and doesn't require much recovery time — usually just a day or so.- Needle drainage of a hydrocele is not done all that often because the fluid usually accumulates again, requiring more treatment.[16]
- Sometimes the needle has to be inserted through the inguinal (groin) area if the hydrocele has formed higher in the scrotum or partially outside of it.
Have the entire hydrocele surgically removed.[17] The most common and effective way of dealing with a persistent and/or symptomatic hydrocele is to remove the hydrocele sac along with the fluid — called a hydrocelectomy.[18] This way, there's only about a 1% chance of the hydrocele developing again.[19] The surgery is either performed with a scalpel or a laparoscope, which has a tiny camera attached to a long cutting device. Hydrocele surgery is typically done at an outpatient clinic under general anesthesia. Recuperation can take up to a week or more, depending if the abdominal wall has to be cut into.- With babies, surgeons usually cut into the groin (inguinal region) to drain the fluid and remove the sac. Stitches are then used to strengthen the muscle wall — which is essentially the same as a hernia repair surgery.
- In adults, surgeons often cut into the scrotum to drain the fluid and remove the hydrocele sac.[20]
- After a hydrocelectomy, you might need a tube inserted into your scrotum to drain any excess fluid for a few days.
- Depending upon the type of hydrocele, surgical repair may be recommended to decrease the risk of a hernia to the area that is cut off from blood supply.
Take it easy while recovering. Recovery from a hydrocele operation is relatively quick in most cases. Otherwise healthy people can typically go home a few hours after surgery — it rarely requires staying overnight in a hospital.[21] Kids should limit their activity (no rough stuff) and get extra bed or couch rest for about 48 hours or so post-surgery. Adults should follow the same advice, as well as delaying sexual activities for up to a week just to be on the safe side.- In most patients following a hydrocele operation, normal activity can restart after 4 to 7 days.[22]
- Potential complications from surgery to look out for include: allergic reaction to anesthesia (breathing problems), bleeding within or outside the scrotum that won't stop, and potential infection.
- Signs of bacterial infection include groin pain, inflammation, redness, a foul odor, and possibly a mild fever.

Board Certified Urologist & Urological SurgeonSmall hydroceles can be monitored if they don't cause pain. However, hydroceles larger than 5 cm in diameter usually make sitting and/or exercise uncomfortable. Surgical removal of the hydrocele is the gold standard treatment to fix the problem. You can have the hydrocele drained via needle in your doctor's office, but this has a high recurrence rate.

Tips
- To ease discomfort after a hydrocelectomy, consider using a scrotal support strap and crushed ice (wrapped in a thin cloth) to help reduce any swelling.Thanks
- Don't be embarrassed to self-examine your scrotum from time-to-time. It's a good way of detecting problems (such as hydroceles) before they develop into more serious conditions.Thanks
- Although unusual, hydroceles can form due to a filarial worm (parasitic) infection of the testes that can lead to severe swelling and elephantiasis.Thanks
Warning
- If your scrotum is painful and begins to swell rapidly, see a doctor immediately.

If you think you have a hydrocele, look for symptoms like swelling in your scrotum that becomes painful when you walk or run. While most hydroceles will drain and get absorbed into the body on their own within 6 months, you can help speed up the process with Epsom salt baths. To get the most out of a salt bath, sit in the water with your legs spread for 15 to 20 minutes, as the warmth will stimulate the movement of body fluids while relaxing your muscles. However, avoid heat if your hydrocele is painful, since any warmth can make your symptoms worse. If your hydrocele doesn’t go away on its own or becomes so big that it causes pain or disfigurement, see a doctor for medical treatment.
