Why are embryos frozen?
Embryos suitable for storage may remain after IVF or ICSI. Freezing can allow them to be used in a later treatment cycle. In some plans, the team may recommend freezing embryos before any transfer takes place.
What is vitrification?
Vitrification is a rapid freezing technique used for embryos. The laboratory uses protective solutions and stores the embryos at very low temperatures. Not every embryo is suitable for freezing, and some may not survive warming.
What happens when I want a transfer?
The clinic reviews your circumstances and plans the preparation for a frozen embryo transfer. The laboratory warms the embryo and assesses whether it is suitable to transfer. Your specialist will explain the schedule for your own cycle.
