How is a varicocele treated?
The most common treatment is surgery. An incision is made in the groin and the spermatic cord (which contains the vas deferens and blood vessels going to the testicle) is examined. Veins are tied off while arteries, the vas deferens, and lymph vessels are left
alone. This surgery is done as an outpatient procedure under either general or local anesthesia.
Two thirds of men see improvement in their semen analyses and about 40% can achieve a pregnancy. An alternative to surgery is embolization, performed by a radiologist. During embolization, the radiologist uses a catheter to put a coil or fluid in the vein to block blood flow through the vein.
What are the risks of varicocele surgery?
Serious complications are rare. Risks include bleeding, infection, injury to the testicle, blood clots in the legs, and the risks of general anesthesia. About 10%15% of men who
have varicocele surgery will have a recurrence or persistence of varicocele after surgery.
