It Takes A Few Days For An IVF Egg To Be Transferred

In the process of ivf egg retrieval and transplantation, there are usually two cases: one is the 3-day frozen embryo transplantation of IVF baby, and the other is the 5-day blastocyst transplantation of IVF baby, which can be determined according to the patient's physical condition. The growth condition before 5 days of embryo transfer of test-tube baby can be divided into the following six kinds: 1. Embryo culture day: after the ova is taken out of the body, it must be immediately put into the prepared embryo culture medium for cultivation in advance, and sperm fertilization will be carried out several hours later. 2, the first day of embryo culture: observe whether the egg has been fertilized in the morning. 3, the second day of embryo culture: observe whether the fertilized egg of test-tube baby divides, is a few cells, whether there are fragments, whether symmetry. 4, the third day of embryo culture: the same day, to see how many cells, to see whether there are fragments and whether symmetry. Typically, two or three embryos are selected for transfer on the third day. The embryo should be 8 cells divided three times, sometimes 4 to 7 cells or larger than 8 cells may appear. If the embryos are not transferred, they should be transferred to a petri dish for approximately 48 to 72 hours. 5. The fourth day of embryo culture: the embryo develops to the morula stage. 6, the fifth day of embryo culture: embryo development to blastocyst stage. At this point, the embryo should have divided more than six times and formed a blastocyst. Some blastocysts have begun to hatch or have hatched completely from the zona pellucida. In the preparation of ivf pregnancy, it is suggested that expectant mothers in the period of taking eggs, reasonable adjustment of work and rest time, so as to contribute to the development and growth of ivf embryos.
