Spermatocele (/spɜrˈmætəsiːl/) 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. Spermatoceles are the most common cystic condition encountered within the scrotum.[citation needed] 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 harmless.
