Varicoceles are enlarged vein that occur in the scrotum. They are thought to affect fertility by causing blood to back up in veins supplying the testicles and also to possibly raise the temperature of the testicles. The effect is damaging to the sperm quality.
There are two types of repair that can be done. The surgical approach involves a small incision to the abdomen using local or general anesthetic whereby the surgeon can clip the vein producing the varicocele. The non-surgical approach involves threading a small catheter through one of the larger veins in your neck or groin to the varicocle, which then can be blocked by a ballon, coil, or medicine, eliminating the varicocele.
Both are outpatient procedures so you can go home the same day and should be able to resume normal activities within a few days.
