What is a spermatocele?

Dr. Mark S. Litwin, MD

A spermatocele is a cyst on the testicle. Doctors often have men visit them because they feel the cyst and worry that it is a tumor. The cyst contains sperm and fluid normally found around the sperm.

If you have a testicle lump, see a urologist or general doctor for an exam. An ultrasound may be done to confirm your diagnosis. If you have a spermatocele, you will not need a follow up appointment. A spermatocele may go away on its own. Or, it may stay the same or get bigger. Doctors say it might just be part of you to have to learn to love.

A spermatocele is an area of abnormal dilatation, or enlargement of the epididymis, a tube that transports sperm from the testicle to the urethra. A spermatocele generally presents as an asymptomatic soft round mass on the back of the testicle. Spermatoceles do not generally require treatment but may rarely be surgically removed as some may cause chronic pain.
