The pros of a freeze-all IVF cycle could be that first of all, we can select and do the treatment at the best moment for the patient at the same time we are also able to do the preimplantation genetic screening of the embryos and it may mean that we need to delay a little bit the embryo transfer, postpone it. So, we can also find the best moment for the patient to undergo the frozen IVF cycle. At the same, it would be also important to consider, as a pro, that we are able, or we can at least offer the patient the task of doing the preparation of the uterus in a natural cycle without adding any estradiol intake to make the endometrium bit thicker. So, in the end, also we make sure that the patient is undergoing the treatment in the most comfortable conditions for them. However, if we are talking about the cons, it means if we freeze all the embryos, we need to postpone the embryo transfer which can cause some problems to the patients. However, it could be the only con that can have that kind of treatment.
