What does frozen embryo grade mean?

The level of frozen embryos is the level of frozen embryos. Frozen embryos are the only way to preserve fertility in a mature way in the world. This technology is to keep the embryos obtained by in vitro culture technology in a liquid nitrogen environment of-196℃ for a long time. Put the embryo and freezing liquid into a freezing tube.

A method of keeping embryos still by slow and rapid cooling and storing them in 196 degree liquid nitrogen. If there are surplus embryos with good quality, they can be frozen and stored, and then implanted into the uterine cavity after thawing in natural cycle or artificial cycle, which will increase the chance of pregnancy. It can be used in a superovulation cycle to obtain a large number of embryos with good quality without one-time transplantation.

In the process of "test-tube baby" for infertile patients, the number of mature eggs is generally increased by stimulating ovulation drugs, which often leads to more than ten eggs growing in the ovary at a time. But in fact, only 1-3 embryos are transplanted back into the uterine cavity in each "IVF" course.

Implanting too many embryos may increase the risk of multiple births, so the remaining embryos can be frozen. If the treatment cycle is unsuccessful, the preserved embryos can be transplanted back to the mother in the future natural ovulation cycle or hormone replacement cycle without superovulation, which not only saves the pain of injection, but also saves a lot of money.
