Spermatocele (Epididymal Cyst) - Topic Overview

What is a spermatocele?

A spermatocele (epididymal cyst) is a sperm-filled cyst in the long, tightly coiled tube that lies above and behind each testicle (epididymis). It feels like a smooth, firm lump in the scrotum on top of the testicle.

What causes spermatoceles?

Although the cause of a spermatocele is often unknown, it may be caused by obstruction of the tubes that carry sperm from the testicles (epididymal ducts).

Don’t Be a Home Improvement Disaster

You walk into Home Depot or Lowe's to pick up a lightbulb. Instead, you leave with some new flooring, a circular saw, a framing square, and big ideas about re-tiling your kitchen. The problem? You've never done anything more than change a lightbulb by yourself. Growing numbers of Americans are tackling do-it-yourself home improvement projects that once might have been left to professionals. One reason for the shift: Stores like Home Depot, along with TV shows on networks like HGTV or the DIY...

What are the symptoms?

Often a spermatocele does not cause symptoms. You may notice what looks or feels like an extra lump or mass above the testicle on one side of your scrotum. Or you may notice a general enlargement of your scrotum. Symptoms, when present, can include pain, swelling, or redness of the scrotum or a feeling of pressure at the base of the penis.

How is a spermatocele diagnosed?

A spermatocele is usually diagnosed by examining the scrotum. As part of the exam, your doctor will shine a light behind each testicle (transillumination) to check for solid masses that may be caused by other problems, such as cancer of the testicle. Spermatoceles are filled with fluid, so light will shine through them (transillumination). Light will not pass through solid masses that may be caused by other problems, such as cancer of the testicle. An ultrasound may be used to confirm the diagnosis of a spermatocele.

How is it treated?

Spermatoceles are not usually dangerous and are treated only when they cause pain or embarrassment or when they decrease the blood supply to the penis (rare). Treatment is not usually needed if a spermatocele does not change in size or gets smaller as the body reabsorbs the fluid.

If the spermatocele gets larger or causes discomfort, a procedure to remove the spermatocele (spermatocelectomy) may be needed.
