The transfer success rate of fresh embryos is higher and has some differences. Because the development of embryos is related to many factors, such as genetic material and environment, frozen embryos may change and the success rate is low. Embryo transfer requires a certain level of hormones in the body to avoid severe rejection and unstable embryo implantation, which can lead to transfer failure. After the transfer, you need to take more rest, avoid strenuous exercise, stay up late, eat a light diet and avoid stimulating food to prevent miscarriage. Pay attention to any abdominal pain, vaginal bleeding, etc. Regular hormone tests and abdominal ultrasound examinations are needed to see how the embryo is developing.
