How to judge the grade of IVF eggs

The development of IVF technology has made many infertile couples realize their dream of becoming parents. For IVF infants, the quality of fertilized eggs is one of the key factors that determine their survival and implantation ability. Therefore, it is very important to evaluate and screen the fertilized eggs. This article will introduce how to judge the level of IVF eggs from the aspects of embryo shape, development speed, genetic normality and the degree of cell fragments.

Embryonic shape

Embryo shape is the first index to evaluate the quality of fertilized eggs. Generally speaking, the normal fertilized egg has a regular shape without obvious abnormality, and the embryonic cells divide evenly with equal cell spacing. The abnormal fertilized egg has irregular shape, uneven division of embryonic cells, and uneven cell spacing. By observing the shape of the fertilized egg under the microscope, we can preliminarily judge whether the fertilized egg is healthy. In addition, some hospitals have introduced AI technology to help judge the quality of fertilized eggs. AI can evaluate the shape of the fertilized egg by analyzing a large amount of data, and give more objective judgment results. This method not only improves the accuracy of evaluation, but also reduces the burden of manual evaluation.

Growth rate

The development rate of normal fertilized eggs is another important evaluation index. Generally speaking, a healthy fertilized egg should gradually develop into a mass of 4 to 8 cells in a culture dish. If it is still single cell or develops slowly in a specific time, it may mean that the fertilized egg has some problems and needs further screening. By observing the development speed of the fertilized egg, the health status of the fertilized egg can be preliminarily judged. Of course, when evaluating the development speed, it is also necessary to make a comprehensive judgment based on the shape of the fertilized egg and other indicators.

Genetic normality

The genetic normality of fertilized eggs is also one of the important criteria for evaluating the quality of fertilized eggs. Chromosome abnormality is one of the main reasons for embryo implantation failure. At present, some hospitals use gene detection technologies, such as PGS (embryonic chromosome screening) or PGD (embryonic gene diagnosis), to screen for genetic abnormalities in fertilized eggs. PGS and PGD technology can help judge whether there are chromosome abnormalities, genetic diseases and other problems in the fertilized eggs. Through the detection of these technologies, doctors can screen out fertilized eggs with normal genetic combination, and improve the success rate of IVF.

Cell debris degree

The degree of cell fragments is one of the important indicators to evaluate the quality of fertilized eggs. Too many cell fragments often mean cell death or deformity, which will affect the viability and implantation ability of the fertilized egg. When evaluating the degree of cell fragments, doctors usually use a microscope to observe the fragmentation of the fertilized egg, and judge the quality of the fertilized egg by calculating the percentage of cell fragments. Higher levels of cell fragmentation may require further screening.

summary

The success rate of IVF is closely related to the quality of fertilized eggs. By evaluating and screening the shape, development speed, genetic normality and cell fragment degree of the fertilized eggs, we can select high-quality fertilized eggs and improve the success rate of IVF. When evaluating the quality of fertilized eggs, hospitals can introduce AI technology to improve the accuracy and efficiency of evaluation. With the progress of science and technology and the continuous development of medicine, the method of accurate assessment of fertilized eggs will be more and more perfect.
