is an abnormal enlargement of the vein
that is in the scrotum
draining the testicles. Upward flow
of blood in the veins is ensured by small one-way valves that prevent backflow. 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. Since there is a structural problem (defective valves, compression), oral
medications are not known to help as it is important to correct the problem. Hence surgery is the best option for conditions like varicocele.
