The most common scale uses a number and two letters to describe each embryo 4AB for example. Transfers using excellent grade blastocysts have a pregnancy rates of about 65. When the blastocyst grade is average studies show the pregnancy rate drops to 50.

What are the success rates of Embryo Grading. Embryo grading results are not objective and reliable They dont explain the internal genetic condition of the embryo. Research has revealed many cases of embryos with poor grades that make a pregnancy and cases where embryos with good grades dont make a pregnancy.

Grading of embryos come at different stages of the embryos growth. Most of the transfers occurs on either of Day 3 or Day 5 the grading. An embryo thats dividing well should ideally have between 6 to 10 cells by day 3.

Research shows that 8 is best. Day 3 embryos that had 8 or more cells showed a significantly. We have broken down the system we use for grading blastocyst success at ORM in the following chart.

The degree of the expansion of the embryos cavity ranging from 2-6. 2 cavity fills 13 of the embryo. 3 partial expansion fills 70 of the embryo.

4 fully expanded cavity. Success rate with fresh embryos. Between 32 years but up to 37 years.

Between 37 years but up to 45 years. That was in 2017. They have since amended their stats and report 70 success regardless of whether transferring one or two PGS normals.

For untested embryos from a young donor their stats are 45-50 when transferring one and 65-70 when transferring 2. So thats quite a. Rhenman 2015 looked at Day 2 single embryo transfers average age 34.

Having 4 cells was ideal 30 live birth and dropped to 3-8 with 2-3 cells 50 was about 10. Live birth rates from poor quality Day 23 embryos are about half what they are from good quality. All they said is AA was the highest rating and BB was good.

When the embryo is 5 it means that half of the embryo has done the hatching and a 6 blastocyst means that the embryo is completely out of the zona pellucida. The embryo is considered regular of intermediate quality with a lower probability of implantation. Its morphological characteristics are as follows.

2 or 6 blastomeres on DAY 2 or 6 or 12 blastomeres on DAY 3. Grade 2 embryo its a good quality embryo with around 10 of fragmentation. They have mostly equal and regular blastomeres.

Grade 3 embryo is an embryo that starts to have quite a bit of fragmentation the blastomeres are not equal in size anymore. You will see small blastomeres and big blastomeres in the same embryo and you might even have amorphous so they are not quite round. 10 common questions about 2 embryo transfer success rate 1 Does transferring 2 embryos increase chances.

Under ideal conditions some embryo transfers can have implantation rates. A simplified system to use for grading blastula success within the following chart. The degree of the enlargement of the embryos cavity starting from 2-6.

2 cavity which fills 13 of the embryos. 3 partial enlargement fills seventieth of the embryo. 4 totally distended cavity.

5 embryo has distended and split open the body structure. In Grade 2 the cells may be uneven in size. Fragmentation of the cytoplasm.

The degree of fragmentation required for the different grades vary according to the center at which the IVF is being performed.
