BACKGROUND Recently described slow-cooling cryopreservation protocols involving elevated sucrose concentration have improved survival frequencies of human oocytes, potentially overcoming a major hurdle that has limited the adoption of oocyte storage. Because implantation rates of embryos from frozen oocytes remain generally low, it is still debated whether, irrespective of survival rates, this ...
Modifying cryopreservation protocols may be seen as a way to simplify cryobanking procedure and increase satisfying outcomes. The aim of the study was to evaluate the influence of slow cooling protocol and vitrification on IVF outcomes using embryos preserved in the 5th or 6th day after oocyte retrieval. The study compared 2 groups of human embryos underwent slow cooling protocol (n=189) and vi...
