In IVF technology, the embryo grading report is one of the most important indicators for assessing embryo quality and success rates. However, many people are often confused when faced with this complex report and its various medical terms. Today, we'll demystify this "report card" for you, helping you better understand embryo grading and fully prepare for your pregnancy preparation journey.

 

 

Embryo grading is a central part of the IVF process for evaluating an embryo's developmental potential. Doctors primarily use a combination of morphological grading and genetic screening (IVF-PGT) to comprehensively assess embryos.

 

- Morphological Grading: This can be understood as the embryo's "appearance," where it is graded by observing its external morphological characteristics.

- Genetic Screening: This focuses more on the embryo's "inner quality," delving into the chromosomal level to ensure the embryo is genetically healthy and stable.

 

By combining morphological grading with IVF-PGT, doctors can evaluate embryo quality from multiple angles, significantly increasing the success rate of IVF and giving prospective parents greater hope for a healthy pregnancy.

 

IVF-PGT analyzes the chromosomes of an embryo to precisely screen for healthy embryos with a normal chromosome count. This effectively reduces the risk of miscarriage and birth defects caused by chromosomal abnormalities. This technology is particularly suitable for older women or couples with a risk of genetic diseases and is a core advantage of IVF-PGT technology.

 

The entire IVF-PGT process typically includes several key steps:

 

1. Biopsy: When the embryo develops into a blastocyst around day 5, a small sample of cells is taken from its outer layer.

2. Genetic Testing: Using molecular biology techniques, such as NGS (Next-Generation Sequencing), the chromosomes of the biopsied sample are analyzed in detail.

3. Comprehensive Grading: Based on the test results, the embryo's chromosomes are evaluated for normalcy. Only embryos with normal chromosomes are considered viable and are prioritized for transfer.

 

An embryo's morphological grade is based on its external features and is assessed primarily on the following aspects:

 

1. Cell Count: On day 3 of embryo development, the ideal cell count should be between 6 and 8.

2. Cell Size and Uniformity: The more uniform the cell morphology, the better the embryo quality.

3. Fragmentation Rate: The fewer fragments produced during cell division, the higher the grade, which indicates healthier embryonic development.

4. Blastocyst Quality: On day 5 of embryo development, the doctor assesses the size of the blastocyst cavity and the quality of the inner cell mass (ICM) and trophectoderm cells (TE), which are key factors in determining whether the embryo will successfully implant.

 

Morphological grading is typically categorized into four grades: A, B, C, and D. Grade A embryos are considered the best quality and are the first choice for transfer. For example, an embryo graded as "4AA" signifies a good developmental stage with Grade A quality for both the inner cell mass and trophectoderm, making it a priority choice for transfer.
