These days, the issues of infertility arise more than often. Even though the medical industry has done a lot to deal with the problem, new methods and techniques continue to emerge regularly. Embryo vitrification is one of the most recent discoveries in the world of reproductive medicine.
The vitrification is usually used when the number of received embryos is high. Some of them get transferred for the woman to get pregnant, while the others are vitrified and stored for later, in case something goes wrong.
If you wonder when it is possible to vitrify an embryo, the method is applicable to all stages up to blastocyst formation.
