It is unlikely that a testicular cyst is due to excessive masturbation. Epididymal cysts can occur with increased frequency in male offspring of mothers who used diethylstilbesterol during pregnancy.
Epididymal cysts are not associated with cancer and no treatment is indicated. If the cysts cause discomfort, they can be removed in an outpatient procedure.
Followup with your personal physician is essential.
