Varicocele Repair for Infertility
Varicoceles are enlarged varicose veins that occur in the scrotum. They are fairly common, affecting 15 out of 100 men overall and 40 out of 100 men with known infertility.1 Varicoceles occur most often in the left testicle.
Varicocele repair is done to improve male fertility. It can usually be done surgically on an outpatient basis using local or general anesthetic. A small incision is made in the abdomen close to where the testicles originally descended through the abdominal wall. The veins that produce the varicocele are identified and cut to eliminate blood flow to the varicocele.
Alternatively, a nonsurgical procedure called percutaneous embolization can be done to repair a varicocele. A small catheter is inserted through a large vein in the groin or neck and advanced to the varicocele, which is then blocked off by a balloon, coil, or medicine.
What To Expect After Surgery
Varicocele repair typically is done on an outpatient basis. You can expect to go home within 4 hours of a routine varicocele surgery. Pain medicine is prescribed for a few days after surgery.
You should be able to resume light work duties 1 to 2 days after surgery and full strenuous activities within 1 week.
Why It Is Done
Varicoceles are thought to raise the temperature of the testicles or cause blood to back up in the veins supplying the testicles. Although the mechanism by which varicoceles affect fertility is poorly understood, varicoceles seem to help damage or kill the sperm.1 Varicocele repair is typically done to improve the fertility of men who have both a varicocele and impaired sperm.
How Well It Works
While some researchers have observed that varicocele repair produces favorable pregnancy rates, others have noted that these pregnancy rates are the same as the rates of couples who have chosen not to have a varicocele repaired.2
What To Think About
There is no proof that fertility rates improve after this surgery. But some doctors think that larger varicoceles are linked to sperm problems. It is also possible that varicocele surgery would improve the semen quality, making other fertility treatments easier.2
Small varicoceles that are only apparent with ultrasound testing do not require repair.
