Spermatoceles can be discovered as incidental scrotal masses found on physical examination by a physician or by self-inspection of the scrotum and testicles.

Finding a painless, cystic mass at the head of the epididymis that is clearly separate from the testicle can indicate a spermatocele.
Shining a light through the mass through a process known as transillumination can also help differentiate between a fluid-filled cyst and a tumor, which would not allow as much light to pass.
If uncertainty exists, ultrasonography of the scrotum can confirm the presence of a spermatocele.
