Learn About Pregnancy Rates
The American Society of Reproductive Medicine is "Infertility's" self-governed body.
The Society for Assisted Reproductive Technology is where fertility centers must report
their statistics. Both societies state that any advertisements of comparative pregnancy
rates include the following:
"As entry criteria are highly variable for each program,
a center-by-center comparison of results is not valid."
As a patient, you are interested in selecting the right fertility center. We are a very
experienced fertility center. We understand what you are looking for but we also understand
how confusing and frustrating it can be. Although we have great statistics, we encourage you
to look beyond statistics and costs to get a total assessment of which center you will trust
with this important decision. The statistics may indicate the competence of a fertility center,
but we regret to inform you that they may indicate something else. Please be careful.
The following provides you with insight to 5 ways in which a fertility center can increase their
pregnancy rates without increasing the care provided:
The Right Type of Patient
Regarding patient selection, who are the right patients? They are young patients, with normal
clomiphene challenge tests, with a previous pregnancy, no prior IVF or gonadotropin IUI failures,
no prior pregnancy loss, short duration of unexplained infertility, known tubal blockage, low FSH
values, and have a partner with normal sperm. These are just some of the criteria an initial
consultation/screening process may include. From two different centers, a couple may hear two different responses:
a) "I'd only be taking your money."
b) "Your chances are lower, but we are willing to help."
"Higher pregnancy rates" will then be used as a marketing tool to lure the right type of patients,
while simultaneously provided difficult patients to the competing fertility center.
The Right Classification of Patient
There are two main ways to classify patients to improve pregnancy rates. The first is research.
If a center has a difficult patient, that patient can be a reseCRM patient. The statistics from
research patients are not reported.
The other method is to convert cycles mid-stimulation. If an IVF cycle stimulation does not
look good, it can be converted to an IUI cycle and avoid reporting. Conversely, if an IUI
cycle looks good, it can be "enhanced" as an IVF cycle and be reported. The patient may
have gotten pregnant anyway.
There are proper times to convert cycles, it is the frequency of this occurrence that should be alarming.
The Right Type of Therapy
There are basically three types of advanced infertility therapy. They are gonadotropin IUI, IVF and
donor IVF. Patients can be encouraged to accept a therapy that is beyond their current need. A patient
likely to get pregnant on a simple Ovulation Induction cycle is even more likely to conceive with an IVF
cycle. This drives IVF pregnancy rates up, and makes the choice between the two therapies even more distinct
and confusing for future patients. The same holds true for IVF patients with somewhat questionable egg quality
and the choice to pursue donor IVF.
The Right Time to Stop Therapy
There are two strategies to improve pregnancy rates regarding stopping therapy. The first is canceling
a cycle mid-stimulation and thus avoiding the reporting requirement. Although canceling a cycle is
sometimes necessary, it is important to know a fertility center's cancellation rate and how often
IVF cycles are converted to Ovulation Induction cycles.
The second strategy is to encourage difficult patients to quit therapy. Although there is a time for
this, typically the pregnancy rates stagnate after the fourth attempt. If a center can avoid the
fifth attempt, their rates will not be compromised.
The Right Embryos
The chance of becoming pregnant increases with the number of embryos transferred. Therefore, some
physicians are more aggressive, and often carry a higher multiple birth rate. (With the existence
of selective reduction, it is important to know multiple rates before reductions.) Sometimes more
embryos are encouraged to transfer because of their "poor quality". Sometimes this "poor quality"
embryo discussion leads to another strategy.
Frozen cycle pregnancy rates are not as high as fresh cycles (or as expensive). Overall pregnancy
rates improve with fewer cycles that are frozen embryo transfers. Therefore, there are subtle ways
to discourage freezing embryos.
The Right Thing to Do
There are many other ways pregnancy rates can be improved. One can just look at a specific time period.
We hope that you will look at all the factors that ultimately make up success. Our experience speaks
for itself. We encourage you to speak to medical professionals about our character, philosophy and
treatment. We are here to help.
