Surgery Overview
Varicoceles are enlarged
varicose veins that occur in the
scrotum. They are fairly common, affecting 15% of men
overall, and 40% of men with known
infertility.1 Varicoceles
occur most often in the left
testicle.
Varicocele repair is performed 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
medication.
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 performed to improve the fertility of men who
have both a varicocele and impaired sperm.
Varicocele repair is a controversial practice. Many infertility
experts express concern that it is not effective as an infertility
treatment.2
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.3, 4
A recent review of research has found no benefit of varicocele
repair for male or unexplained infertility.2
Risks
- Infection at the site of
surgery
- Fluid buildup in the scrotum (hydrocele) that requires
draining
- Injury to the arteries or nerves in the pubic area
What To Think About
There is no proof that fertility rates improve after this surgery.
However, 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.4
Small varicoceles that are only apparent with
ultrasound testing do not require repair.
