Embryo cryopreservation is a process where embryos are frozen and stored in liquid nitrogen for future use. This technique allows individuals or couples undergoing in vitro fertilization (IVF) to preserve embryos for future use . Prior to cryopreservation, embryos are monitored and assessed for their developmental stage and quality. 

Here’s an overview of the embryo cryopreservation process: 

1. Selection for Freezing: Embryos that have reached a certain stage of development, exhibit normal morphology, and have a high likelihood of surviving the freezing and thawing process are selected for cryopreservation. Embryo(s) that do not meet the criteria will not be selected fr cryopreservation. The number of embryos frozen depends on various factors, including the individual's age, egg/sperm quality, and fertility diagnosis. 
2. Cryopreservation and Storage: The selected embryo(s)are first placed in cryoprotectant solutions to protect them during freezing. The embryo(s) are then loaded onto their predetermined cryopreservation device. Cryopreservation devices are labeled to ensure proper identification. They are then transferred to storage tanks filled with liquid nitrogen, where they are stored for later use without significant loss of viability. 
3. Thawing and Transfer: Once the individual or couple is ready for their transfer, the selected embryo(s) will then be thawed in a controlled manner. The thawed embryo(s) are transferred into the uterus of the female partner or gestational carrier (GC). 

Embryo cryopreservation offers several benefits, including the ability to preserve embryo(s) for future use, and the option to pursue pregnancy later without the need for additional egg retrieval procedures. It is an important step for individuals or couples undergoing fertility treatment who wish to maximize their chances of achieving pregnancy.
