Scrotal mass
Scrotal mass


A scrotal mass is a lump or bulge that can be felt in the scrotum, the sac that contains the testicles.

Alternative Names:

Hematocele; Spermatocele

Causes, incidence, and risk factors:

A scrotal mass can be benign (generally harmless) or malignant (cancerous). Benign scrotal masses include:

  • Varicocele -- a varicose vein along the spermatic cord
  • Hydrocele -- fluid collection in the scrotum
  • Hematocele -- blood collection within the scrotum
  • Spermatocele -- a cyst-like mass within the scrotum that contains fluid and dead sperm cells

Scrotal masses can be caused by inflammatory or infectious diseases (for example, epididymitis ), physical injury to the scrotum, herniation (inguinal hernia ), or tumors.


Signs and tests:

During a physical examination, the doctor may feel a mass within the scrotum and make note of its features:

  • Tender or non-tender
  • Uniform, smooth, twisted, or irregular
  • Fluctuant (feels liquid), firm, or solid
  • Typically only on one side

The inguinal lymph nodes in the groin may or may not be enlarged or tender on the affected side.

The following tests may be performed to help diagnose a scrotal mass:

To discover any lumps as early as possible, all men should perform testicular self-examination each month.


ALL scrotal masses should be evaluated by a primary health care provider. Hematoceles, hydroceles, and spermatoceles are usually harmless and do not require treatment. Sudden, temporary conditions may respond to local comfort measures and, in some situations, antibiotics or pain relievers.

A scrotal support (jock strap) may provide some relief of the pain or discomfort associated with the scrotal mass. A hematocele, hydrocele, or spermatocele may occasionally require surgery to remove the collection of blood, fluid, or dead cells.

Expectations (prognosis):

Most conditions that cause scrotal masses can be easily treated. Even testicular cancer has a high cure rate with early diagnosis and treatment. Nevertheless, any scrotal mass should be examined promptly by a qualified doctor.


Complications depend on the underlying reason for the scrotal mass. For example, varicoceles may lead to infertility.

Calling your health care provider:

Call your health care provider if you find any kind of lump or bulge within your scrotum.


Scrotal masses linked to sexually transmitted diseases (for example, epididymitis) may be prevented by practicing safe sex.

Scrotal masses resulting from injury may be prevented by wearing an athletic cup during exercise.

Monthly testicular self-examination can catch testicular cancer early, and improve the chances of curing it. All men 15 years or older should learn how to perform testicular self-examination.
