An epididymal cyst is a non-cancerous (benign) growth filled with clear liquid which is found at the top end of the testis (testicle) where the spermatic cord (vas deferens) is attached. This area is known as the epididymis.
Men are most likely to develop epididymal cysts around the age of 40. Children rarely get them before they become teenagers. The exact number of people who develop epididymal cysts is unknown.
If the cyst is small and is not causing a problem you may not need treatment. You just need to keep an eye on it and seek medical advice if it gets larger or becomes painful.
Large or painful cysts can be removed surgically. The operation is a simple one and recovery is usually uneventful. The procedure is usually performed under a general anaesthetic and on a day case basis. The procedure itself takes about 30 minutes and is performed through an incision in the scrotum using absorbable stitch material.
