Symptoms

A spermatocele usually causes no signs or symptoms and might remain stable in size. If it becomes large enough, however, you might feel:

• Pain or discomfort in the affected testicle
• Heaviness in the testicle with the spermatocele
• Fullness behind and above the testicle

When to see a doctor

Because a spermatocele usually doesn't cause symptoms, you might discover it only during a testicular self-exam, or your doctor might find it during a routine physical exam.

It's a good idea to have your doctor evaluate any scrotal mass to rule out a serious condition, such as testicular cancer. Also, call your doctor if you experience pain or swelling in your scrotum. A number of conditions can cause testicular pain, and some require immediate treatment.
