The preimplantation embryo undergoes dynamic changes in energy demand during development. Oxygen consumption rate (OCR), representing overall oxidative metabolism, has been reported in several species but few studies have examined the components of OCR. Individual blastocyst OCR was measured using a non-invasive oxygen probe (unisense), whereas OCR of grouped blastocysts was determined using the Oxygen Biosensor fluorometric assay (BD Bioscience). Respiratory chain inhibitors ...
