Embryo cryopreservation, or embryo freezing, is done on the 3rd or 5th day after egg retrieval. This is highly successful, and has no adverse effect on the embryo at all. This allows healthy embryos, which are not transferred to be saved, i.e. frozen. Should the transfer of fresh embryos be unsuccessful, or should you want another baby, these embryos can be thawed and transferred at a later date. This is a highly successful procedure, and allows for the transfer of embryos without going through the process of ovulation induction, and oocyte retrieval. The shelf life of the embryos is indefinite. Some couples that want or need to postpone pregnancy can electively have all the embryos cryopreserved. This is important as age and fertility are intimately linked in women. We are using Vitrification method
