When and at what age a couple wants to have a child does not have to be limited because of a biological clock. Cryopreservation given couples the choice to have a child at a later stage in their life as well. This process can help people preserve fertility and let couples get pregnant any time in the future. Cryopreservation is the process of freezing eggs, sperm, or embryos to sub-zero temperatures for later use. When the eggs, sperm or embryos are needed, they are thawed and fertilized or used in a fertility treatment cycle.

- Two methods can be used for cryopreservation at IVF labs: vitrification and slow freezing. In recent years, vitrification has become highly popular and has been used more increasingly because of the benefits it offers, including low risk of cell damage.
- It is possible to freeze the embryo at any point prior to the blastocyst stage. The blastocyst stage occurs 5-7 days after fertilization. Before freezing the embryos, a cryoprotectant solution is used for lowering the freezing point of the embryo. This step is necessary for preventing ice crystals from forming inside the cells, which might cause damage.
- Frozen embryos are known to be extremely resilient. They remain frozen safely for extremely long durations. Around 2/3rd of embryos do not get harmed from freezing and thawing. There have even been cases of frozen embryos from 20 years ago being used to help couples get pregnant successfully.
