Clinically, there are often such patients, because the remaining embryos have a relatively low score, they are less willing to transfer, afraid that the embryo quality is too poor to give birth to the baby is prone to deformity. So, if the IVF embryo score is very low, will it be prone to deformity? AA69 Fertility Center consulted a professional IVF specialist to see the answers.
First, let's take a look at how embryologists rate embryos.
In general, embryo ratings are related to several factors, the number of cells in the embryo, the degree of uniformity of cells after division, and the degree of fragmentation. Here is a relatively common grading method, from the first level to the fourth level, the first level is the best, the fourth level is the worst:
Primary cells divide evenly; No debris
Secondary cell division is uniform; There are a few fragments
Grade 2.5 cells divide roughly evenly, with some fragmentation
Tertiary cell division is uneven; There are no fragments or some fragments
Tetralevel cell division is uniform or uneven; Fragmentation is severe.
It can be seen that the embryologist's rating of the embryo is only observed by the naked eye, so the embryo seen by the naked eye may be of good quality, but its developmental potential may not be very good. On the contrary, embryos that do not look very good do not necessarily develop poorly, and the score of the embryos does not indicate whether the child is healthy or not, and whether there will be deformities after conception.
In general, there is no difference between the high-rated embryos and the rated embryos, and the deformity rate of the pregnancy is not the same, because many abnormal embryos cannot implant and cannot be conceived smoothly.
And the development process of the embryo is an extremely delicate and complex process, if it is disturbed in the process of cell development (the influence of the internal and external environment), it is easy to cause malformations, so whether it is natural pregnancy or IVF fertility, pregnant mothers should pay attention to stay away from teratogenic factors, do a good job of obstetric examination, and be responsible for the healthy development of the fetus.
The rating of the embryo does not mean that the embryo with a low score on the health of the embryo is also likely to implant smoothly and successfully conceive!
