Epididymal cyst removal surgery. Surgeon operating on a 58-year-old man with a benign (non-cancerous) cyst on the epididymis of his right testicle. The epididymis is a narrow tightly-coiled tube of the male reproductive system that carries sperm from the testes (testicles). It connects the efferent ducts from the rear of each testicle to its vas deferens. Here, the testicle (lower centre) and epididymis (red, upper centre) have been exposed through an incision in the scrotum (top).
