Embryonic diapause [a] (delayed implantation in mammals) is a reproductive strategy used by a number of animal species across different biological classes.In more than 130 types of mammals where this takes place, the process occurs at the blastocyst stage of embryonic development, [1] and is characterized by a dramatic reduction or complete cessation of mitotic activity, arresting most often ...
This process usually takes about a week; after that, implantation happens. "[Implantation] usually occurs about 5 days after fertilization," explains Dr. Langdon, but of course, every body is ...

As of 2019, only contraceptives are commercially available.
