"Blastocyst formation does not mean that embryos are normal. We are performing PGD and i noticed that chromosomally abnormal embryos might reach to blastocyst stage, even 3PN do so sometimes.<br>
Age, as mentioned before Endometrium thickness might also affect the implantation.<br>
As for the sperm, abnormalities in sperm such as (genes, chromosomes, centromere...)even if they were morphologically normal might also affect. Partcularly from OAT pateints. It might be related to Y chromosome microdeletions. <br>
Hope this will help."

"A hatching blastocyst does not mean it will implant. A 3PN embryo can reach blastocyst stage and even hatch, but does not result in a pregnancy. Chromosomal normality, endometrial receptivity all affect implantation"
