IVF procedure is used to treat infertility in
couples when all other assisted reproductive technology failed to provide the
results. IVF depends on a many factors and hence the success rate of IVF also
varies. The outcome of IVF procedure is different for different women. Learn
more about the factors affecting IVF and the success rate here.
When an individual patient or a couple chooses the IVF
procedure the average statistics may not be contextually applicable. There are
a host of factors that determine the outcome of the IVF
procedure and thus ascertain its success rate.
Factors Affecting IVF
age of the woman - This gives a clear picture of her ovarian reserve.
status of the uterus – whether it is absolutely normal, the quality of the
semen must also be cultured.
success or failure rate of the fertilisation
and cleavage in the vitro procedure.
total number, the maturity level and the quality of eggs that are
retrieved play a vital role too.
total number of embryos that have been transferred and cyro-preserved
the luteal phase post transfer is adequate or not
of infertility is also a major factor that determines the success rate
of the IVF
It is also important to note here, the success rate of the
IVF increases with the increase of the IVF stimulation attempts. It usually
ranges for a maximum of 3-4 stimulation cycles.
The Other Relevant
The success rate also depends on how well the physician or
the clinic supports a couple wanting to undergo the IVF procedure. It has been
found that when the patients are not preselected, there are maximum chances of
the women attaining their dream to become mothers. Female patients who are low
responders and those who have a failed IVF cycle in the past should not act as
deterrents. But pregnancies are found to happen in many of these ‘negative’
cases as well.
The success rate can be improved when a female who is older
than forty-three years, or has an FSH level that is higher than 15 mIU /ml on a
basal cycle day – 3, can be asked to opt for egg
donations. This increases the chances of conception a lot.
With the rise in the number of IVF stimulation attempts, the
success rate also increases simultaneously. The most recent results for the IVF
and the donor egg cycles are taken into account along with the cyro-cycle pregnancy
rates and the combined pregnancy rate for the current decade. All these factors
determine the potential reproductive success rate.
How is IVF Success
Females with a good prognosis, that is who are less than 38
years of age have a positive chance of thawed embryo transfer or
cyro-preservation. They generally have a normal ovarian reserve that is
determined through serum day – 3 FSH level and they also have undergone
stimulation through the luteal or the Lupron protocol. It has been observed
that those who receive donor eggs and have a great prognosis contribute in
higher success rates.
The options to enhance the odds of pregnancy are to freeze
the extra pre-embryos or to go for repeated attempts. Patients, who are able to
produce a fair amount of healthy embryos, can actually have a pregnancy option
at their disposal at a comparatively much lower cost, thus resulting in cost
The other important factor comprises of the reproductive
potential success rates. This is basically the number of pregnancies resulting
from a single stimulated cycle. This ought to follow from a fresh embryo
transfer cycle along with an additional cycle of the transfer of the
cryo-preserved embryo that is obtained from the same stimulation. Apart from
being cost effective, this enhances the chances of pregnancy by over 60%.
