An epididymal cyst (ep·i·did·y·mal - cyst) – also known as spermatocele (sper·mato·cele) – is a cyst on the scrotum on top of the testicle.
Overview
What is a pediatric epididymal cyst (spermatocele)?
A spermatocele (epididymal cyst) is a fluid-filled cyst that develops in the long, tightly coiled tube that is located above and behind each testicle (epididymis). The fluid in the cyst may contain dead sperm. A spermatocele feels like a smooth, firm lump in the scrotum on top of the testicle. Having an epididymal cyst does not affect fertility.
