Nowadays, there is not enough medical evidence to say that we need to offer elective freezing in all IVF cycles. It’s true that we perform that kind of technique quite often, in many IVF cycles for different reasons. The main reason is that we are increasing the number of patients that undergo preimplantation genetic screening of the embryos and because of that all the embryos should be frozen before we get results from the geneticists. However, it doesn’t mean that if a patient is not undergoing that testing in the embryos, the patient has to undergo that kind of technique I mean, that the patient needs to do the elective freezing of all the embryos because is not clear that the result could be better. Of course, there is a medical reason to recommend freezing the embryos but it doesn’t mean that all patients need to do that because the data that we have at this moment doesn’t say that the implantation rate could be higher in that kind of cycle.
