The role for HIF in oocyte maturation is less understood, as efforts to replicate the low oxygen environment of the in vivo follicle are not achievable by culturing in low oxygen alone. There is potential for other factors present in vivo, but lost in vitro, to be involved in oxygen regulation. One factor of interest is haemoglobin, the oxygen-binding protein, which brings the exciting possibility of sensitive oxygen regulation, consequently affecting HIF-regulated gene expression. A thorough understanding of oxygen regulation within
