                                        A quick guide to Egg Vitrification
                                    
                                    
                                        Women’s eggs are difficult to freeze – they are the biggest cell in the body and contain a large amount of water. Previous freezing techniques had a low egg survival rate because the water inside the cell created crystals that destroyed it. 90% of the eggs survive the vitrification process and 98% of these eggs then survive the thawing process.
