In
Infertility/IVF
treatment tests have major role
and many doctor go for series
of tests. For doctor it’s much
easier to order a test than
to talk to the patient, which
means that many doctors will
mindlessly order a battery of
tests in order to make a diagnosis.
Few patients ( or even doctors
for that matter) , question
the cost effectiveness or utility
of these tests, which are mechanically
performed on a “routine” basis,
especially in many US clinics.
“Overtesting”
just wastes money, sometimes
it does have more serious consequences.
Ordering tests is easy, but
interpreting them intelligently
is hard ! Consider the common
example of the presence of “pus
cells “ found in a semen analysis.
Often these cells seen on microscopic
examination are actually sperm
precursor cells which are found
in normal semen. However, they
are very commonly misreported
as “pus cells” and many doctors
then promptly label the man
as having a genital tract infection,
and treat him with an endless
variety of antibiotics, in order
to try to “clear up “ the infection.
The unreliability of medical
tests also poses a major problem
today. The most obvious reason
can be attributed to laboratories
whose functioning is marked
by factors such as poor quality
control, unskilled manpower
and obsolete equipment.
Unfortunately, when infertile
patients change their doctor,
many doctors insist on repeating
all the tests all over again,
because they do not trust the
results of any lab other than
their own. This is very unfortunate,
and patients often end up wasting
even more time and money.
Ironically, it is true that
sometimes doctors do tests because
the patients demand them. This
is very common, for example,
with couples who have unexplained
infertility, who often demand
that the doctor continue performing
tests till he can accurately
diagnose what the reason for
their infertility is.
What is our approach towards
testing our patients ? We try
to simplify testing, by explaining
that there are only 4 things
we need to test:
-
eggs
-
sperms
-
uterus
-
and
tubes.

The semen analysis to check
the husband's sperm count and
motility, after requesting him
to abstain from ejaculation
for at least 3 days .
The wife's blood is then tested
for measuring the levels of
her four key reproductive hormones:
prolactin, LH ( luteining hormone)
, FSH ( follicle stimulating
hormone) , TSH ( thyroid stimulating
hormone). Since these levels
vary during the menstrual cycle,
they should be done between
Day 3-5 of the cycle.
We then do a hysterosalpingogram
(an X-ray of the uterus and
tubes) for her after the menstrual
bleeding has stopped - between
Day 5-7, to confirm her uterus
and tubes are normal.
We then see the couple on Day
9 with all these reports and
review the results . These three
basic tests allow us to check
whether the eggs, sperm, uterus
and tubes are normal.
Here are some of the tests which
many doctors will subject their
infertile patients to, which
we feel are wasteful and unnecessary.
An
endometrial biopsy ( EB ) or
D&C ( dilatation and curettage)
for endometrial sampling
-
TORCH tests.
-
Doppler
test
-
Sperm
function tests
-
Laparoscopy.
-
PCR
for endometrial TB.
-
Immune
testing for patients
with repeated IVF failures
and repeated miscarriages
.

Interestingly, just like over-testing
can lead to problems, we have
also noted that under- testing
can be equally problematic !
Thus, we have seen many men
who have been advised to undergo
IVF treatment, based on the
report of just a single semen
analysis report, which was abnormal.
It is essential that the semen
analysis be repeated, after
a period of 4- 6 weeks, to confirm
that the abnormality is persistent,
because sperm counts do vary
considerably, even in normal
men.
You should also make sure that
your doctor examines your original
scans and X-rays, and not just
the reports, because his interpretation
may be different from the radiologist's.
If you have undergone a series
of scans, they should be arranged
in chronological order, so that
the doctor can compare them
easily.
Here's a checklist of questions
you should ask your doctor when
a test is recommended:
1. Why is the test being ordered?
2. How definitive is the test?
Is it the 'gold standard' for
making the diagnosis? Will it
reveal for sure that a condition
is present or not, or must it
be repeated or followed by more
sophisticated tests?
3. What precisely will the doctor
be looking for in the results
of these tests? What does he
hope to learn from the tests?
How accurate are they?
