title: A crucial step in assisted reproduction technology: human embryo selection using metabolomic evaluation.
abstract: We present a new methodology to predict embryo viability in assisted reproductive technology (ART) treatments by determining the relative amino acid concentrations in human embryo culture medium on day 3, using high-performance liquid chromatography with mass spectroscopy analysis without derivatization. The model was performed with soft independent modeling of class analogy for the samples from nonpregnancy and pregnancy cases.
