When a patient has a varicocele causing pain or low sperm counts, correction may be recommended. This is performed by laparoscopic varicocelectomy or microscopic varicocelectomy. Laparoscopic varicocelectomy involves small incisions made in the abdomen to fill it with gas. Clipping of the vein is performed where the vein originates in the abdomen. Microscopic varicocelectomy involves a small incision in the groin and then clipping all the veins individually.
