Mitochondrial DNA quantity as a biomarker for blastocyst implantation potential

Mitochondrial DNA quantity as a biomarker for blastocyst implantation potential
Of all the factors currently available for the evaluation of embryonic potential, chromosomal status appears to be the most definitive. The debate around this hotly contested issue does not focus on the question of whether aneuploidy is detrimental to development, but on whether current preimplantation genetic testing for aneuploidy methods are capable of accurately determining whether an embryo is chromosomally normal, aneuploid or a mixture of normal and abnormal cells (i.e., mosaic). Despite the importance of aneuploidy, it is clear that this is only one factor amongst many of relevance to embryo viability, as evidenced by the fact that even the transfer of a chromosomally normal embryo cannot guarantee a pregnancy.
