In this study, study investigators will collect embryo culture media on day 5 of vitro fertilization (IVF) culture, prior to vitrification and embryo transfer for testing via Metabolomic screening. Metabolomics is a new, non-invasive method of embryo selection which involves testing discarded embryo culture media for analytes secreted by the developing embryo. These analytes can be used to determine the implantation potential, and ploidy, of the embryo. This study will take place at multiple locations in the United States and Spain.
