Varicocele causes

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

A varicocele forms when valves inside the veins along the spermatic cord prevent blood from flowing properly. This causes the blood to back up, leading to swelling and widening of the veins. (This is essentially the same process that leads to varicose veins, which are common in the legs.)
