Small cysts are best left alone, as are larger cysts that are an asymptomatic condition. Only when the cysts are causing discomfort and are enlarging in size, or the patient wants the spermatocele removed, should a spermatocelectomy be considered. Pain may persist even after removal.

Spermatocelectomy can be performed on an outpatient basis, with the use of local or general anesthesia.

A spermatocelectomy will not improve fertility.

Ultrasound is useful if the cause is not certain based on the above measures. If the diagnosis of torsion is certain, imaging should not delay definitive management such as physical maneuvers and surgery.

Spermatocele () is a retention cyst of a tubule of the rete testis or the head of the epididymis distended with barely watery fluid that contains spermatozoa. Small spermatoceles are relatively common, occurring in an estimated 30 percent of all men. They vary in size from several millimeters to many centimeters. Spermatoceles are generally not painful. However, some men may experience discomfort from larger spermatoceles. They are not cancerous, nor do they cause an increased risk of testicular cancer. Additionally, unlike varicoceles, they do not have a negative impact on fertility.

Fournier's gangrene ( an aggressive and rapidly spreading infection of the perineum ) usually presents with fever and intense pain. It is a rare condition but fatal if not identified and aggressively treated with a combination of surgical debridement and broad spectrum antibiotics.

An epididymal cyst is a cyst of the epididymis containing serous liquid. They are difficult to differentiate from a spermatocele except by aspiration, since a spermatocele contains milky-appearing sperm.
