The degree of achieved blastocyst expansion is dependent on TE functionality, including the success of adjuvant blastomere compaction, and tight-junction formation, and the capacity of various cellular mechanisms to pump water and other ions in and out of the cell.[34] It is possible that the degree of blastocyst expansion does not predict the pregnancy outcome because at the analyzed stage of development, this parameter does not yet affect embryonic development.
