Reduction in oxygen tension to 2% in extended culture: a more physiologic system may mean more blastocysts available for transfer

Since the earliest days of IVF, embryo culture systems have been designed to mimic the in  vivo environment to the highest degree possible. Exhaustive studies of the normal conditions of the female reproductive tract have produced our contemporary culture systems, with carefully calibrated amino acid and carbohydrate substrate levels, precise pH control, and tight temperature regulation . However, the facet of embryo culture that has perhaps received the greatest research attention is oxygen tension.
