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
- A feeling of heaviness in the testicle with the spermatocele
- A mass, or 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, be sure to 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.
