Without any doubt, the more eggs we have, the better chances for the patient. I know that for some years, we’ve been told that at some point, the extra oocytes that we can get from a cycle may not be of the same quality compared to if we just get 7-8 eggs.

However, I think that current evidence is strong enough to confirm that this is not true. The more oocytes we get, the more embryos we’re going to have, the higher the chances to get that optimal embryo. If we don’t get that, the higher chances that the patients can get pregnant after the first or second cryotransfer without having to go through a new IVF or stimulation again.

When we do IVF, we’re always aiming at trying to get as many eggs as we can.

This is a question that we hear a lot. Actually, I always say the same thing. Because fertility is related to age and the quality of the eggs, everything is related to the number of eggs. We depend, of course, on the eggs that we have. It’s the same thing. The more eggs we have the better options we have to find the good egg and the good embryo that we’re looking for.

What do we do to try to have a good number of eggs? We stimulate the ovaries with hormones that we give, an external medication that we give. And we try to get the maximum number of follicles that we can. This, of course, depends on the ovarian reserve that the patient has because this is something that we cannot change.

Every month we work with what we. We cannot change that. The thing is that we give a certain dose of hormones to try to boost all the possible follicles, but always within a safe level for the patient. For example, when we want to do everything personalized, we depend on the age of the patient, on the height and the weight of the patient, and on the ovarian reserve of the patient, all these factors. We take these factors into consideration to know what dose to give to every patient. For example, we avoid problems like ovarian hyperstimulation syndrome, which is related to a high ovarian reserve in a high ovarian response. So that’s the reason we always try to do everything personalized, but the general idea is the more eggs we have the better options we have.
