Hey there! Let’s chat about something really important in the world of fertility—grading embryos. If you’re diving into the journey of IVF, understanding embryo grading can be super helpful in navigating your options.
When an egg is fertilized, it begins a fascinating journey of development. Specifically, we look at something called pronuclei. For example, a normally fertilized egg has two pronuclei—one from the mother and one from the father. However, sometimes things can go awry, and you might end up with an egg that has three pronuclei due to two sperm fertilizing it. Unfortunately, this usually leads to the embryo not surviving past 48 hours because it has too much genetic material.
Grading of Embryos
Now, let’s talk about the actual grading of embryos.
- Grade 1: Picture this—a perfect 8-cell embryo with cells that are all the same size, no fragments, just beautiful harmony. This is the gold standard!
- Grade 2: Here, we have an embryo that’s a little behind the curve with only 5 cells when it should ideally have 8. The cells are also of different sizes, which puts it in the grade 2 category.
- Grade 3: This one has 8 cells but comes with a lot of cellular fragments. The sizes of the cells are uneven too. However, a positive sign is that the cells are flattening against each other, indicating the embryo is alive and trying to develop.
