What percentage of donor eggs can make blastocysts?

The number of blastocysts and the quality of different parameters have a direct influence on one another. These parameters include the quality of donor eggs after the thawing, the quality of an IVF laboratory, experience of the embryologist and sperm quality.
If all these conditions are adequate, we expect a blastocysts rate of up to 50% of from donor eggs. However, of course, the number of blastocysts and quality of blastocysts alone will not give a complete depiction of a patient’s chance of pregnancy. We still need to consider the genetic potential of an embryo, as this is a very important factor.
