Variococele Repair
Varicoceles are dilated veins in the scrotum surrounding the testes.
Approximately 15% of all men have varicoceles and for most men, they do
not seem to impair testicular function. However, about 40% of all
men
with infertility have varicoceles and it is generally believed that
their presence, impairs sperm production. Although the precise
pathophysiological mechanisms of the varicocele effect have not been
delineated, many investigators believe that a secondary increase in
testicular temperature causes impaired spermatogenesis. Whatever the
cause, many studies have demonstrated that.
A varicocele is made up of enlarged veins within the scrotum. They
are similar to varicose veins of the legs. Varicoceles are found in
about 15% of the normal male population and about 40% of
men with
infertility. Most evidence indicates that
varicoceles can hinder sperm
production often resulting in infertility. It is important to remember
that female factors can also contribute to infertility. Therefore,
successful outcomes can depend on both partners being treated. Both you
and your partner should have complete evaluations before any
treatment
choices are made.
Not all men with varicoceles are infertile. However, most
infertile
men with varicoceles have improvement of semen quality after
varicocele
repair, and some infertile men with
varicoceles are able to achieve a
conception after varicocele repair.
Varicoceles are found by doctors on
physical examination. Further tests include at least two semen analyses
which may be performed to find out whether the
varicocele is associated
with infertility. Once an evaluation is completed, your doctor can tell
you about treatment options that are available for you and your partner.
To the doctor, a varicocele feels like a bag of worms when you are in
the standing position.
If you are your partner are trying to conceive a child and you have
been told you have a varicocele, you should think about
treatment when
the following are present:
- The varicocele can be felt when your doctor examines the
scrotum.
- Your and your partner have been unable to get pregnant.
- Your partner has normal fertility or a treatable cause of female
infertility.
- Your semen analyses or sperm function tests are not normal.
There are a number of surgical options, and your doctor will discus
with you the details of these approaches. Surgical repair of a
varicocele is done in an outpatient surgical center with general or
local anesthesia. The operation takes about an hour. Surgery for
surgical correction of a varicocele is successful in 90% of cases and
about 60% of men have improved sperm count and motility after repair of
the varicocele. About 40% of couples will subsequently initiate a
pregnancy following varicocele repair. Many urologists prefer an
operative approach that employs microscopic techniques. The use of this
higher magnification better ensures prevention of damage to other
important structures with effective ligation of those veins contributing
to the varicocele.
