Abstract

Selection of the most viable embryo to transfer and at which stage of development remains one of the most challenging aspects of in vitro fertilization. There is little consensus regarding the observations to make and how frequently to record them. Many schemes use a combination of criteria, including the addition of pronuclear morphological scores, early cleavage, and more controversially aneuploidy screening, as adjuncts to those used routinely. Attempts to draw conclusions on the effectiveness of current observational embryo grading and selection tools have been hampered by a lack of generic terminology and methodology. There is a clear need for a standard embryo scoring/selection system and the introduction of external quality assessment schemes, currently being piloted in the UK. It is hoped that with the introduction of consistent terminology and reduced operator scoring variability, this will permit large-center studies and allow more definitive correlations to be drawn leading us closer to defining what indicates a viable embryo. There is increasing evidence to support the proposition that amino acid profiling reflects the developmental capacity of early embryos. By measuring a group of 18 compounds, amino acid profiling provides a snapshot of embryo phenotype by virtue of the many roles played by amino acids during embryo development. Amino acid profiling differs from conventional metabolic assays, where typically, only one or two metabolites are measured.
