Fig. 1From: Transferrin and antioxidants partly prevented mouse oocyte oxidative damage induced by exposure of cumulus-oocyte complexes to endometrioma fluidEffects of endometrioma fluid on mitochondrial polarization of mouse oocytes. COCs were denuded and stained for mitochondrial function. a, d Green fluorescence indicates low polarized mitochondria (δΨm ≤ − 100 mV). b, e Red fluorescence indicates high polarized mitochondria (δΨm ≥ − 140 mV)Back to article page
