Has anyone had a varicocele embolization? What can I expect?

Ask Doc... The experience from varicocele embolization will be just like a patient receiving angiography - an arterial imaging study by interventional radiologist. However, the degree of pain/pressure may highly vary depending upon the varying complexity ; patient's tolerance/coping ability among individuals. Note: the detail of a procedure is never the same among individuals; it's fact of life.
Yes . This was popular 20-25 years ago and may still be done some places. The idea is to put something into the spermatic vein to promote clotting in the vein. This prevents the retrograde flow of blood to the testis.
