Scrotal masses
Testicular mass; Scrotal growthA scrotal mass is a lump or bulge that can be felt in the scrotum. The scrotum is the sac that contains the testicles.
Causes
A scrotal mass can be noncancerous (benign) or cancerous (malignant).
Benign scrotal masses include:
- Hematocele -- blood collection in the scrotum
- Hydrocele -- fluid collection in the scrotum
- Spermatocele -- a cyst-like growth in the scrotum that contains fluid and sperm cells
- Varicocele -- a varicose vein along the spermatic cord
Varicocele
A varicocele is the swelling of the veins inside the scrotum. These veins are found along the cord that holds up a man's testicles (spermatic cord)....

Scrotal masses can be caused by:
- Abnormal bulge in the groin (inguinal hernia)

Exams and Tests
During a physical exam, your health care provider may feel a growth in the scrotum. This growth may:
- Feel tender
- Be smooth, twisted, or irregular
- Feel liquid, firm, or solid
- Be only on one side of the body
The inguinal lymph nodes in the groin on the same side as the growth may be enlarged or tender.
The following tests may be done:
- Biopsy

Treatment
A provider should evaluate all scrotal masses. However, many types of masses are harmless and do not need to be treated unless you are having symptoms.
In some cases, the condition may improve with self-care, antibiotics, or pain relievers. You need to get medical attention right away for a growth in the scrotum that is painful.
Self-care
Testicle pain is discomfort in one or both testicles. The pain can spread into the lower abdomen.
If the scrotal mass is part of the testicle, it has a higher risk of being cancerous. Surgery may be needed to remove the testicle if this is the case.
A jock strap or scrotal support may help relieve the pain or discomfort from the scrotal mass. A hematocele, hydrocele, spermatocele, or scrotal abscess may sometimes need surgery to remove the collection of blood, fluid, pus or dead cells.
Outlook (Prognosis)
Most conditions that cause scrotal masses can be easily treated. Even testicular cancer has a high cure rate if found and treated early.
Have your provider examine any scrotal growth as soon as possible.
Possible Complications
Complications depend on the cause of the scrotal mass.
When to Contact a Medical Professional
Contact your provider if you find a lump or bulge in your scrotum. Any new growth in the testicle or scrotum needs to be checked by your provider to determine if it may be testicular cancer.
Prevention
You can prevent scrotal masses caused by sexually transmitted diseases by practicing safe sex.
To prevent scrotal masses caused by injury, wear an athletic cup during exercise.

Hydrocele - illustration
A hydrocele is a collection of fluid inside the area of the scrotum, surrounding the testicle. Hydroceles are common in newborn infants and normally resolve after a few months after birth. The main symptom is a painless, swollen testicle, on one or both sides, which feels like a water-filled balloon. Hydroceles are usually not dangerous, and they are usually only treated when they cause discomfort or embarrassment, or they get so large that they threaten the blood supply of the testicle.

Spermatocele - illustration
A spermatocele is a cyst-like mass that forms within the epididymis. It is usually filled with fluid and dead sperm cells. A spermatocele can be left untreated unless it is growing too large or causing the individual discomfort.
