Is 8 fertilized eggs a good number?

Having at least 6-8 fertilized eggs is certainly desirable, and frequently there are more than this. How is embryo quality assessed? By 72 hours, or Day 3 of development, the most favorable embryos consist of at least 6 cells, and an embryo with 7 or 8 cells is considered ideal.

What percentage of fertilized eggs make it to Day 5?

Remember, even if all of your embryos are perfect on day 3, on average only 40-50% of them will become blastocyst on day 5.

How many eggs can be injected with ICSI with IVF?

If IVF is being done, all eggs are going to get inseminated (as eggs are left in their fluffy cumulus cells) and the next morning we will see which ones are fertilized. Again, the immature ones will not fertilize. With 12 eggs collected, 10 can be injected with ICSI, or only 10 will be able to be fertilized by the sperm with IVF.

What percentage of eggs that are retrieved will fertilize?

Generally, 70 to 80 percent of the eggs retrieved will fertilize. The average may be lower if sperm or if egg quality is a known problem. Some attrition at this stage is normal and expected. Step 3: Embryos that make it to Day 5 (blastocyst)

Do all eggs get inseminated during IVF?
