Vitrification is an exciting new technique which is used to cryopreserve (freeze) supernumerary eggs and embryos. Using ultrarapid (flash) freezing techniques, it's now possible to efficiently store spare eggs and embryos, so they can be used later on to achieve a pregnancy after thawing. Because our embryologist, Dr Sai , has so much experience and expertise, our survival rates after vitrification are nearly 100% .


The principle is simple. Vitrification is dependent on the placement of the oocyte/embryo in a very small volume of vitrification medium which is then cooled at an extreme rate, so that the embryos are flash frozen and preserved intact.

Because our thaw survival rates after vitrifying are so good, we now advice all our patients to freeze all their embryos - even if they have only one - and to then transfer them in the next cycle, when endometrial receptivity is optimised for allowing implantation to occur.
