Considerations

A testicular lump that doesn't hurt may be a sign of cancer. Most cases of testicular cancer occur when men are between ages 15 and 40, although it can happen at older or younger ages.

Common Causes

Here are some possible causes of a painful testicle:

• Injury or trauma
  
• Epididymitis
  
• Infection of the scrotal sac
  
• Mumps
  
• Orchitis (testicular infection)
  
• Testicular torsion
  
• Testicular cancer
  
• Spermatocele (a cyst-like mass within the scrotum that contains fluid and dead sperm cells)
  
• Varicocele (a varicose vein along the spermatic cord)
  

Here are some possible causes if the testicle is not painful:

• Testicular cancer
  
• Hydrocele (fluid collection in the scrotum)
  
• Varicocele
  
• Spermatocele
  
• Loop of bowel from a hernia
  

Call your health care provider if

Call your health care provider right away if you notice any unexplained lumps or any other changes in your testicles.

What to expect at your health care provider's office

Your health care provider will perform a physical examination, which may include inspecting and palpating the testicles and scrotum, and ask questions about the lump, such as:

• When did you notice the lump?
  
• Have you had any previous lumps?
  
• Is there any pain?
  
• Does the lump change in size?
  
• Is only one testicle involved?
  
• Exactly where on the testicle is the lump?
  
• Have you had any recent injuries or infections?
