is an abnormal enlargement of the vein that is in the scrotum
draining the testicles. The testicular blood vessels originate in the abdomen and course down through the inguinal canal
as part of the spermatic cord
on their way to the testis. Upward flow of blood in the veins is ensured by small one-way valves that prevent back flow. Defective valves, or compression of the vein by a nearby structure, can cause dilatation of the veins near the testis, leading to the formation of a varicocele.
No diet or exercise can cure it.Surgery is the only answer for varicocele.
