About the procedure

Varicocele Embolization is a minimally-invasive IR procedure used to treat the development of varicose veins known as varicoceles in the testicles or groin area. This condition affects approximately 10% of all men. Typical symptoms of these swollen veins are mild and may not require treatment, but occasionally they can cause pain, fertility problems, and atrophy (shrinkage) of the testicles.


In healthy veins, one-way valves keep the blood flowing the right direction – from the testicles and scrotum back to the heart. But in a varicocele, the valves malfunction and become “leaky,” allowing blood to flow in the reverse direction, which causes the affected veins to become enlarged.

One of the most common symptoms of varicoceles is an aching pain, often felt when the person has been standing or sitting for an extended time, allowing pressure to build up in the swollen veins. This pain is sometimes brought on or made worse by lifting heavy objects.

Another symptom of varicoceles can be infertility or subfertility. Although no direct cause-and-effect relationship has been proved, one study found that 40% of men who were subfertile had varicoceles. Other studies have found that the presence of varicoceles can be linked to decreased sperm count, decreased sperm motility, and an increase in the number of deformed sperm. The mechanics of this link have not been determined, but one theory is that the varicoceles raise the temperature of the testicles and thus hinder sperm production. Some studies have shown that men with fertility problems often see an improvement in sperm quality and quantity after treatment to repair the varicoceles. As a third symptom, untreated varicoceles can result in impaired blood flow and the shrinking or atrophy of one or both testicles.

Varicoceles are often diagnosed during a physical examination, because the presence of the swollen veins can make the scrotum appear lumpy. A suspected diagnosis of varicoceles can be verified via noninvasive imaging such as color flow ultrasound.

Traditional treatment of varicoceles has usually involved invasive surgery, which involves general anesthesia, incisions and stitches, and often a long and painful recovery period. Varicocele Embolization provides a minimally-invasive varicocele treatment that is as effective as surgery, but with less risk, less pain, and much less recovery time.

What to expect

The Varicocele Embolization procedure is an outpatient procedure, and one that is so gentle that patients almost never have to stay overnight in the hospital. During the procedure, the interventional radiologist inserts a catheter into a tiny incision in the jugular vein in the neck. The catheter is then guided using X-ray to the damaged veins. The catheter then uses filament-bearing coils or Sotradecol foam to clot the blood and seal the faulty vein.

After a short stay in the recovery area, patients usually return home the same day. You may be advised to avoid strenuous activity for 24 hours, but most patients return to their full activities in a day or two. In rare cases there may be some minor bruising at the catheter insertion site, and some patients report nausea or a backache, but this is uncommon. There is no effect on sexual function.

Studies have shown that Varicocele Embolization can improve semen analysis. And although there is no 100% guarantee, some studies have shown that pregnancy rates improve after varicocele repair by 30 to 50%.
