Embryo Grading Basics
In order to ensure patients have the best chance for a successful IVF cycle, it is important that embryologists select the highest quality embryos for transfer. The process of grading embryos uses several points of evaluation in an attempt to identify the embryos that are most likely to result in a pregnancy. Using high quality embryos is one of the best ways to improve the success rate of IVF treatment. However, selecting a quality embryo does not guarantee success of an IVF cycle. Grading systems are a means of standardizing the subjective process of determining embryo quality.
Grading System Explanation
There are a number of things that embryologists evaluate while grading embryos:
- The number of cells in an embryo – As an embryo matures, the number of cells contained within it increases. Embryos with a slower rate of cell increase may be less suited for a successful pregnancy than other embryos developing more quickly.
- Cell size – The next step is to evaluate the size of the cells within the embryo. The cells within an embryo should be uniform in size. If large size discrepancies exist, that may be indicative of a larger medical complication.
- Fragmentation – Sometimes, sections of cells within an embryo can break off, resulting in fragments inside of the embryo. Less fragmentation is indicative of a healthy embryo.
Ideally, embryos will have a large number of cells that are of an equal size paired with low fragmentation. Generally speaking, the number of cells within an embryo is considered the most important factor. For example, an embryo with eight cells and moderate fragmentation may be seen as more favorable than an embryo with four cells and little fragmentation.
