The difference between a high-quality embryo and an ordinary embryo is that a high-quality embryo has a high developmental potential, with uniformly sized and regularly shaped blastomeres that are virtually free of fragments, while an ordinary embryo cell is the opposite. High-quality embryo blastomeres are uniform in size, regular in shape, and almost free of fragments. Compared with high-quality embryos, ordinary embryos have significantly lower developmental potential, not as high developmental potential as high-quality embryos, serious irregularities in size and shape as well as in the color and density of individual cells, too slow development, more fragmentation, and the use of these embryos will reduce the success rate of IVF. However, it does not necessarily mean that all regular embryos are bad embryos. Blastocyst culture of them eliminates the poor quality embryos and enables the regular embryos left behind to develop and form blastocysts. After transferring the embryos, women should be careful to take pregnancy tests on time. If the pregnant woman has abdominal pain and other symptoms, it is recommended to seek medical treatment in time, under the guidance of the doctor, improve the relevant examination, clarify the cause of the disease, and symptomatic treatment.
