Abstract

Since Hertig and Rock (1,2) described human embryonic development from fertilization until the late implantation stage, very few morphological studies on the human peri-implantation embryo have been reported (3,4,5). Hertig and Rock’s material detailed the normal light-microscopic morphology of the human embryo until the blastocyst stage, and from the implanted blastocyst until the 17th day of gestation. Unfortunately, they were unable to include the implanting blastocyst stage. Human embryos have been studied in detail at the ultrastructural level during the immediate preimplantation (3) and early postimplantation (days 10–11) stages. Thus, morphological information about the process of implantation itself is still lacking for the human.
