This is an important, well-established form of treatment. Often fertility treatments, such as IVF, ICSI and egg donation, generate surplus healthy embryos. In around 50% of cases these embryos are of good enough quality to be frozen and stored for future use.
Embryos are cooled under controlled conditions and immersed in liquid nitrogen at low temperatures (-196ºC) in a tank for long-term storage. Once frozen, embryos can be stored in this way for many years before being thawed and used in treatment. Pregnancies have been reported from frozen-thawed embryos stored for more than 9 years. The risk of birth defects is not increased as a result of embryo freezing.
Vitrification is the most common method used for the embryo freezing, widely considered as the best method for this purpose including and the egg freezing. At Life Clinic, paying attention to every detail that can contribute to success, we are only using the best freezing kits in the market (and of course the most expensive Kitazato’s kit).
Embryo freezing maximises the use of embryos produced from a fresh cycle and increases the chances to conceive from the same batch of embryos. The use of frozen-thawed embryos is much less invasive procedure for the woman than undergoing a fresh IVF cycle.
Also, it ensures the future use of unused embryos in order to reduce the number of multiple births and offers to couples greater flexibility in their family planning. An annual fee is charged for embryo storage.
