These types of embryos have a low probability of implanting, as their quality is poor. They have signs of degeneration, serious morphological alterations such as high fragmentation or vacuolization, or an abnormal division rhythm. It is advisable to avoid transferring this type of embryos but if there is no other of better quality they can be transferred. Even if the possibilities are low, they could lead to pregnancy.
Is it possible to do a D-grade embryo transfer?
