Embryo Freezing

Cryopreservation of eggs, sperms, and embryo

Cryopreservation is a technique in which organelles, tissues, cells are stored at low temperatures to maintain their vitality. It is used to preserve sperms, eggs, and embryos for the process of in-vitro fertilization (IVF) or infertility treatments. The sperms, oocytes, embryos are usually thawed and cryopreserved to be used in the fertility treatment cycle.

IVF is a technology used for the treatment of infertility and gestational surrogacy.

Cryopreservation of Embryo

It is a process of freezing and storing extra embryos left during the IVF cycle. An embryo may be cryopreserved at any stage between day one and day seven after egg retrieval.

It provides one with another opportunity for getting pregnant if the IVF performed for the first time fails.

Embryo Freezing


The eggs and sperms are fused in the labs, or the healthy embryos are selected.

The embryos are then treated with the cryoprotectant to prevent cryo injury.

Following methods are used for performing cryopreservation of the embryo.

Slow freezing

In this method, the embryo is slowly frozen, and the cryoprotectants are added gradually in increasing concentrations.

The embryo is then slowly frozen in a machine and is immersed in liquid nitrogen at -196° C.


It is a rapid freezing method in which the embryos are directly placed in liquid nitrogen after adding cryoprotectants. This process changes them into a solid-state without the formation of ice.
