Uterine Preparation for Blastocyst Attachment

Existing models used to analyze uterine receptivity to blastocyst attachment have thus far failed to account for non-genotypic embryonic loss following in vitro fertilization and embryo transfer in any species. Although application of the technology for biochemistry and molecular biology has yielded useful information about the uterus at a molecular level, the regulatory mechanisms of ovoreceptivity and implantation remain elusive.
