The number of fertilized eggs could be good or bad depending on how many eggs were inseminated. It means that if we have 3 eggs that have been fertilized, and we have done ICSI on 12 eggs, the outcome is going to be poor because the standard fertilization rate is 80-85%. If we only got 3 eggs and all 3 fertilized, that’s going to be a good outcome for that cycle.

However, that is the first step of fertilization. Then, depending on the age, what we want is day 5 embryos, blastocysts. If we have 3 embryos and the patient is 32, it seems quite likely that we may get 1 or 2 blastocysts. If the patient is 43, and we only have 3 embryos, it seems very difficult that we can end up with a good transfer.

Once more, the fertilization rates, the number of eggs, the number of embryos that we get could be good or bad depending on the patient’s age.

A very important thing to know about that is the age of the patient. I’m sorry for that. We, fertility experts, are always talking about that because we don’t know what the quality of the eggs is. So that’s why we are always talking about age because we have the statistics related to age and the quality of the eggs.

Three fertilized eggs is not a very high number. Of course, it will depend on how many eggs we have. So, for example, you can have three eggs from the egg retrieval. Three of them were mature and three of them are getting fertilized. It’s a good thing. It’s a good thing because we have the maximum that we could.

But, of course, if we had, for example, six mature eggs and just three were fertilized. We have to look for other strategies in case we do another cycle to try to increase it if it’s possible. I think that with patients that, for example, are less than 35 years old, three fertilized eggs could lead to have 1-2 embryos to transfer. So probably that would be the outcome. On the other hand, if the patient is over 40, because of age and quality, probably these three fertilized eggs would not meet one or two embryos and probably a maximum of one. There would be no embryo. It is something that is very age-dependent. And of course, it depends on every patient as well because the quality depends on every person.

Again, it depends on the age of the patient and concomitant diseases. For patients under 35, IVF programs are often suitable in a natural cycle. Always, the use of mild stimulation, where we receive one, two, or three oocytes. It is also a good prevention of hyper-stimulation syndrome.

About this question:

What is the chance that 3 fertilitzed oocytes will lead to day 3 or day 5 embryo?

Is having 3 fertilized eggs a good prognosis for a successful IVF? Is this age-dependent? How many eggs usually get fertilized during IVF?
