Abstract
At 120 hours, there are distinct differences in degree of development of embryos within the same litter. Some embryos are beginning implantation, i. e., the blastocyst closely adheres to the undamaged uterine epithelium (Fig. 32). In other cases, there is advanced erosion of the mucous membrane. Some 4-day embryos are also closely adhered to the undamaged uterine epithelium, and so the beginning of implantation is estimated to occur at 4 1/2 days.
