Swollen testicle: A cause for concern?

A swollen testicle or scrotum with no other signs or symptoms can have many causes. These include:

• Fluid accumulation, such as a hydrocele or spermatocele
• Enlargement of the veins around the testicle (varicocele)
• Tumor

Typically, a testicular tumor is very firm to the touch and painless. Testicular tumors are most common in young men between the ages of 20 and 40 years old. Swelling caused by fluid accumulation or enlarged blood vessels is usually soft and compressible.

Even if your husband has no pain, he should be evaluated by a doctor to determine the cause of the swelling.
