All veins contain valves that reduce back pressure and keep blood flowing in one direction - toward the heart. If one of these valves becomes weak or fails to function properly, back pressure can build up inside the vein, producing a pool of heavy, stagnant blood. Over time, this pooled blood and back pressure can build up enough to cause swelling in the vein, producing a varicose vein or varicocele.
It is helpful to draw an analogy between the body's circulatory network and the cooling system in an automobile. Most people know that a typical automobile engine is protected from overheating by a system that circulates a cooling fluid through it in a continuous loop. A similar process occurs in the human body: blood pumped to the outer extremities by the heart is cooled to a constant temperature as it returns through the veins.
However, because blood flows sluggishly through a varicose vein, cooling of the blood in a varicocele is incomplete. When a varicocele develops in one of the veins of the spermatic cord (known collectively as the pampiniform plexus), the temperature of the blood within it increases. This, in turn, raises the temperature of the testes. Because sperm are sensitive to heat, this increase in temperature can decrease the production of healthy sperm, leading to male infertility.
Although a varicocele can develop in either or both testicles, in most men the problem occurs on the left testicle. There is a physiological reason for this, too: The spermatic cord on the left side is longer and takes a more circuitous route back toward the heart. It connects to the left kidney vein, which has higher blood pressure within it. The higher blood pressure on this side increases the likelihood of swelling in a weakened vein. By contrast, the right testicular vein is usually shorter. It connects directly to the vena cava - the primary vein leading to the heart - which is characterized by lower blood pressure. For this reason, varicoceles of the right testicle are uncommon.
