Lower extremity venography is a test used to see the veins in the leg. X-rays are a form of electromagnetic radiation like light, but of higher energy, so they can go through the body to form an image on film.
The network of veins often appear visibly blue through the scrotum and feel like a bag of worms . When the patient lies down symptoms are less evident. Varicose veins people get in their legs are similar to a varicocele. Varicoceles can lower a man's sperm count and undermine the quality of his sperm.he valves in the veins that go along the spermatic cord do not work properly, a similar process as varicose veins in the legs. A defect in the valves leads to a backflow of blood into the pampiniform plexus, raising pressure there and causing the veins to dilate, and eventually damaging testicular tissue.
