Varicocele as a cause for male infertility

Varicocele
July 2008

Varicocele is a network of tangled blood vessels in the
scrotum which prevents the normal circulation of blood
through the veins in the testicles, causing low sperm
count and infertility. It's not sure what causes varicoceles,
but it is believed that abnormal valves within the veins
prevent normal blood flow. The resulting backup causes
the veins to dilate.

Varicoceles usually occur in the region of the left testicle,
most likely because of the position of the left testicular
vein. Varicocele do not often produce symptoms. If you
feel pain or notice any abnormality, you should see
doctor.

Varicoceles are very common. About 20% of all men
have them. For males who are infertile, the figure is
higher — about 40 percent. Varicoceles are the most
common cause of low sperm production and decreased
sperm quality. However, not all of these cause infertility
or need to be treated.

Researchers has found that embolization, a minimally
invasive radiological procedure can correct the problem,
and improve a couple's chances of having a baby. In
embolization, doctor inserts a small catheter into the
groin and place that catheter in the varicocele. Then, the
doctor inserts a tiny platinum coil and an agent to ensure
the closure of the gonadic vein. Most patients have a
short recovery time and are able to go home next day
More than 95 percent of the time the procedure corrects
the problem.

A study showed, on average, that sperm motility and
sperm count had significantly improved.

Other treatments include open surgery and laparoscopic
surgery.
