What is embryo freezing?
Embryo freezing could be a procedure that enables embryos to be preserved for later use. the primary healthy maternity resulting from freezing a woman’s fresh embryos was within the 1980s. Since then, several embryos are frozen for later use.
The embryos are also kept to lead to a next time maternity, to donate to others, for medical analysis or for testing functions.

The process begins by utilizing hormones and different medications to stimulate the production of probably fertile eggs. The eggs are then extracted from the woman’s ovaries to either be impregnated in a research laboratory or frozen for later use.
Successful fertilization could result in at least one healthy embryo, which might then be transferred to the woman’s female internal reproductive organ or uterus. Hopefully, the embryo can develop and also the woman will carry the developing kid through maternity to a birth. Since fertilization typically ends up in more than one embryo, the remaining embryos may be preserved through freezing. The main goal of embryo freezing is to preserve the embryo for later use. The largest issue is that the water inside the cells. Once water freezes, crystals will be formed. This enlargement will burst the cell, inflicting it to die.
To prevent this from happening, the water within the embryo’s cells is replaced with a protective substance known as a cryo-protectant. The embryos are left to incubate in increasing levels of cryoprotectant before they’re frozen.
Once most of the water has been removed, the embryo is cooled to its preservation state through one among 2 ways of embryo freezing:

Slow freezing: This involves protecting the embryos from harm in sealed tubes then slowly lowering the temperature within the tubes. This prevents the embryo cells from ageing and turning into injured. Embryos will last for much longer in their frozen state than in their contemporary state. However, slow freezing is long, and it needs expensive machinery.

Vitrification: during this method, the cryoprotected embryos are frozen so quickly that the water molecules within the embryos don’t have time to make ice crystals. This helps to guard the embryos and to extend their survival rate throughout thawing.
After freezing, the embryos are kept in liquid nitrogen until they’re required for future use.

Success rates of thawing frozen embryos

The process of thawing an embryo is comparatively made. Some analysis has indicated that embryos frozen through vitrification have an improved probability of endurance, each at the freezing stage and through thawing.

Which countries provide Time-lapse embryo imaging?

Most of the countries like Denmark, UK, Russia, Turkey, Cyprus, Georgia, India, Greece, Sweden, Albania, Andorra, Hungary, Romania, Spain, Dubai, France, Italy, Bulgaria, Estonia, Norway, Switzerland, Finland, Azerbaijan.
