Fresh embryos are fertilized eggs formed by the combination of sperm and eggs. Early embryos will be formed in about 3 days and are usually implanted in IVF treatment; while frozen embryos are cultured and high-quality embryos are stored in - 196 degrees, waiting for the appropriate cycle for embryo implantation. Frozen embryos (frozen embryos) refer to phone database embryos that are stored in liquid nitrogen at -196°C, thawed and implanted in the uterine cavity when the mother is in good condition. Embryo freezing technology began in the 1980s. Dr. Johnson from Australia froze fertilized eggs, thawed them, and implanted them back into the mother's body. After the successful birth of a frozen baby at the end of 1984, it is still widely used in IVF treatment. There are two reasons for needing to freeze embryos: The mother itself still needs time to recuperate, such as polycystic patients, hormonal problems and difficult implantation, cancer/ovarian surgery, etc. Due to fertility planning, such as being limited by the restriction of IVF embryos, not planning to have children for the time being, and wanting to have a second baby in the future, etc. According to the "Artificial Reproduction Law", although the frozen embryo is limited to ten years, it is recommended that couples who have a childbearing plan should still prepare well in advance to avoid becoming a high-risk elderly mother.
