Embryo freezing is the process where embryos created in the laboratory are frozen using the latest Vitrification technique (also known as fast freezing) and stored safely for future use.
Embryos can be frozen as a way of preserving fertility or as part of IVF treatment, where any embryos of good quality not transferred are frozen. Any embryos frozen can be thawed and transferred into the womb during a simple procedure called a Frozen Embryo Transfer.
Frozen embryos have a longer history of success than frozen eggs and can give women more freedom to choose when to have a baby. Frozen embryos may offer women a better chance of a successful pregnancy in later life than trying to conceive naturally or using their older, fresh eggs in fertility treatment.
