Scrotal cysts are almost always removed through a minor outpatient surgery, though many don’t need removal at all. The type of cyst you have, whether it sits on the skin surface or deeper inside the scrotum, determines the specific procedure. Most scrotal cyst removals take under an hour, use local or general anesthesia, and allow you to go home the same day.
Which Type of Scrotal Cyst You’re Dealing With
The word “scrotal cyst” covers a few different things, and the removal approach depends entirely on which one you have. The two most common types are epididymal cysts (including spermatoceles) and sebaceous cysts.
Epididymal cysts form inside the scrotum, typically at the top of the epididymis, the coiled tube behind each testicle. They’re filled with clear or slightly cloudy fluid and are remarkably common. Ultrasound studies find them in 20% to 40% of men with no symptoms, and some research puts the number as high as 75%. When these cysts contain sperm and protein debris, they’re called spermatoceles. Most are tiny (2 to 4 mm), but they can grow to 5 cm or larger.
Sebaceous cysts sit in the skin of the scrotum itself. They form when oil glands get blocked, creating firm, round lumps just under the surface. These are the ones you can see and feel on the skin, unlike epididymal cysts which sit deeper inside.
An ultrasound is the standard way to tell these apart. It shows the cyst’s exact location, size, internal contents, and whether blood flow is present, which helps rule out anything more serious.
When Removal Is Actually Necessary
Most scrotal cysts, particularly epididymal cysts and spermatoceles, don’t require treatment. They generally don’t cause pain or complications, and “watching and waiting” is the default recommendation. Over-the-counter pain relievers like ibuprofen or acetaminophen can manage mild discomfort if it comes and goes.
Removal typically becomes the right call when a cyst is large enough to cause persistent pain or pressure, when it keeps growing, or when it interferes with daily activities. Cosmetic concern is the usual reason for removing sebaceous cysts on the scrotal skin, since they’re visible and can multiply. There’s no strict size cutoff that automatically triggers surgery. The decision comes down to how much the cyst bothers you.
How Epididymal Cysts Are Surgically Removed
The procedure for removing an epididymal cyst or spermatocele is called a spermatocelectomy (or epididymal cystectomy). It’s performed as an outpatient procedure under local or general anesthesia.
The surgeon makes a small incision, usually around 10 mm, through the scrotal skin and the underlying muscle layer called the dartos. Once the cyst wall is visible (it appears slate grey), the cyst is punctured and drained. The fluid inside is typically crystal clear or slightly cloudy. After enough fluid drains to expose the cyst wall, the surgeon grasps the wall, pulls it through the incision, and cuts it away completely. Any remaining attachments are sealed off with heat or tied. The incision is then closed with dissolvable stitches.
The entire procedure is designed to remove the cyst wall in one piece. This matters because leaving fragments behind increases the chance the cyst will refill and come back.
How Sebaceous Cysts Are Removed
Sebaceous cysts on the scrotal skin are removed using what’s called the minimal excision technique. The surgeon makes an elliptical (oval-shaped) incision around the cyst and removes it whole, including the entire cyst sac. Removing the sac intact is critical. If the capsule ruptures during removal, remnants left behind can seed a new cyst in the same spot. The incision is closed with dissolvable stitches.
When multiple sebaceous cysts are present, they can usually all be removed in the same session. Each cyst is sent for examination under a microscope to confirm it’s benign, which is routine.
Why Aspiration Isn’t a Lasting Fix
Needle aspiration, where a doctor drains the cyst fluid with a needle, is sometimes offered as a less invasive alternative. It can provide temporary relief, but the cyst wall stays in place. Because the structure that produced the fluid is still there, the cyst typically refills. Aspiration is sometimes paired with injecting a chemical irritant to scar the cyst wall shut, but this approach still has higher recurrence rates than surgical excision. For most people who want a cyst gone permanently, surgery is the more reliable option.
Risks and Complication Rates
A study of 222 patients undergoing scrotal surgery for benign conditions found an overall complication rate of 27.4%. That sounds high, but most complications were minor and self-resolving. The breakdown: hematoma (blood pooling at the surgical site) occurred in 9% of cases, infection in 5%, recurrence or persistence of swelling in 7.2%, and chronic pain in just 0.2%.
The complication that deserves the most thought is potential damage to fertility. The epididymis is the passageway sperm travel through after leaving the testicle. Surgery in this area carries a small risk of scarring or blocking that pathway, which could affect sperm transport on the treated side. For this reason, doctors often recommend delaying spermatocelectomy until you’re done having children. If the discomfort is too significant to wait, sperm banking before surgery is worth discussing.
What Recovery Looks Like
You’ll go home the same day. The stitches are dissolvable and don’t need to be removed manually. Expect some swelling, bruising, and soreness in the first few days. Wearing supportive underwear or a jockstrap helps reduce movement and discomfort during this period.
Light activity is fine shortly after the procedure, but you should avoid sports, heavy lifting, and strenuous exercise for three to four weeks. Swimming in pools or open water should wait at least two weeks to reduce infection risk at the incision site. Most people return to desk work within a few days, though physically demanding jobs may require one to two weeks off. The area can remain tender for several weeks even after the incision has healed on the surface.
Ice packs (wrapped in cloth, applied for 15 to 20 minutes at a time) help with swelling in the first 48 hours. Over-the-counter pain relief is usually sufficient for managing discomfort during recovery.
