The quick answer to that question is no. It is not because of the COVID-19 that we’ll be using a freeze-all policy. Within our clinic and many other clinics in the UK and worldwide, there’s been a move towards frozen transfer cycles anyway, and there is growing evidence, and there is published literature to indicate that the chances of a successful IVF cycle ending with a live birth are not significantly affected by the freezing, thawing and transfer of blastocyst. In our centre, the live birth rate of cycles, with the transfer of frozen versus fresh blastocysts is very much the same. This will certainly depend on the patient population, on the quality of the embryos, but more importantly on the freezing and thawing expertise policies and procedures available within each lab. Within our laboratory, we have 98% of our cryopreserved blastocysts that survive the thawing process, so 98% of blastocysts survive and are suitable for transfer.
