Considering its stage and development stage, the embryologist will determine which one has the highest implantation potential. Even though class C embryos (low quality) have a limited implantation chance, some are able to cause a pregnancy. For this reason, if an embryologist considers that there are chances for it to implant and there are no other embryos of better quality, it will not be discarded but chosen for the transfer.
If you see a poor-quality embryo in a video, do you automatically discard it?
