Embryo Freezing And Storage
Often after a cycle of IVF or ICSI, there are a number of successfully fertilized embryos that we can freeze and store for your future use. Whether your cycle was successful or unsuccessful, frozen embryo transfer gives you another chance of pregnancy from the initial egg collection with a much reduced cost and without having to go through an egg collection again.
There are two methods of embryo freezing: slow freezing and vitrification. Slow freezing has been used for many years with good results, but vitrification is a newer method showing much higher success rates – often as high as fresh transfers.
The embryologist will decide if any of your embryos are suitable for freezing. They do need to be of good quality as poor quality embryos do not survive the freezing/warming process.
