Hi, Varicocele treatment may not be necessary. However, if your varicocele causes pain, testicular atrophy or infertility or if you are considering assisted reproductive techniques, you may want to undergo varicocele repair... Percutaneous embolization. This procedure is done during local anesthesia on an outpatient basis. A radiologist inserts a tube into a vein in your groin or neck through which instruments can be passed. Viewing your enlarged veins on a monitor, the doctor releases coils or a solution that causes scarring to create a blockage in the testicular veins, which interrupts the blood flow and repairs the varicocele. This procedure isn't as widely used as surgery.
