Spermatoceles are often found at a man's testicular self-exam, or by a doctor at a health exam. Self-exams should be done at least once a month. Your health care provider can train you in the right technique. If you note any suspicious changes, such as larger size or unusual firmness, you should call your health care provider.
Light can be shined through a spermatocele. This generally shows if the mass looks like a solid tumor or a benign (not cancerous) cyst. Ultrasound (a test using sound waves to make images of organs) is a better way to check a cyst. This method is relatively quick, noninvasive and inexpensive.
