- Hi, this is Dr. Hossam Elzeiny.
I am one of the fertility specialists with Melbourne IVF.
I'm a sub-specialist in infertility
and reproductive endocrinology,
working with Melbourne IVF for 20 years now.
How many eggs we are expecting to get from the IVF cycle?
This is a good question.
And for us to answer that,
we would say it depends on the goal
and the purpose of doing the IVF cycle.
Obviously we know that we want to end up
with a child at the end, a live birth,
but at the same time,
we also want to take certain things into consideration
like safety.
And also we may take what we call
cumulative pregnancy rate in consideration,
like having more than one child from one side.
So we can say that the response of the patient
during the IVF can be divided into four or five categories,
depending on the number of eggs
that we will collect from them.
And obviously the number of eggs will depend
on the egg reserve of the patient,
and the amount of hormones that they are taking
during the cycle.
So before starting the cycle, we do our measurements,
we check the AMH,
we do an ultrasound to check the antral follicle count,
and then we come up with the dosage that will give us
the number that we are aiming for.
Now, as we said before,
depending on the number of eggs that we have,
we consider patients who have up to four eggs,
low responder.
And then we have between five and nine eggs,
we call them sub optimal responder.
And then you have from nine to 15,
that's the normal respond.
And then from say 15 to 20 is okay region.
After that,
we are putting ourself in risk
of developing ovarian hyperstimulation syndrome.
So there are situations when we want to get more eggs,
say, we want to be in the zone of between 15 and 20 eggs,
like say patients who are doing egg freezing, for example.
We can once, from one cycle only
we can get the number of eggs that we need,
or patients who are doing genetic testing for their embryos.
They will need decent number of eggs
so that they can have decent number of embryos
that can be tested.
Obviously,
there are studies that has been done to show
what is the number of eggs that is associated
with the highest pregnancy rate.
And we find that between 13 and 15 eggs,
that is what's required in a standard IVF cycle.
And then after these, if we have bigger numbers after that,
then the success rate will plateau,
but you may have a higher cumulative pregnancy rates.
Like with having more embryos,
you probably can have more children in the future.
So it is the judgment of the clinician
to be able to tell at the end of the stimulation,
if the patient is going to respond overly or not,
and here we also can prevent ovarian hyperstimulation
from happening by giving the patient
a specific type of treatment.
So the treatment is much more safer than before,
but also this is not going to give us the,
the green light to, to, to overstimulate the patients.
But between 13 and 15 eggs,
this is the perfect number for the ovarian stimulation.
And I wish the best for every couples.
