A spermatocele (SPUR-muh-toe-seal) is an abnormal sac (cyst) that develops in the epididymis — the small, coiled tube located on the upper testicle that collects and transports sperm. Generally painless and noncancerous, a spermatocele usually is filled with milky or clear fluid that may contain sperm.
The exact cause of spermatoceles is unknown but may be due to a blockage in one of the tubes that drains sperm.
Spermatoceles, sometimes called spermatic cysts, are common. They typically don't reduce fertility or require treatment. If a spermatocele grows large enough to cause discomfort, your doctor may suggest surgery.
