The natural cycle of transfer can be tested regularly through follicular development testing, embryo transfer, and blood HCG testing. This can help patients improve the success rate of embryo transfer. 1. Follicular development test: Follicular development test usually starts from the ninth day after the end of menstruation, which is to detect the development of follicles through ultrasound, to observe whether the follicles are ruptured and the time of discharging eggs, and the doctor will take out the eggs for the patient when they are mature. 2. Embryo transfer: After removing the sperm and eggs, the embryo will be fertilized in vitro. After successful fertilization, the embryo will be cultured for 3-5 days, and then the fertilized egg will be implanted into the mother’s body for gestation, and progesterone will be implanted into the mother’s body to help pregnant women replenish the luteinizing body within the body, and to assist in preservation of the fetus. 3. Blood HCC test: It can help detect the implantation of the fertilized egg in the mother and observe whether the conception is successful. If after the IVF transplantation, the patient’s body has uncomfortable symptoms, it is recommended to consult a doctor in time.
