GLRX and endometriosis: Our redox experiments, using microinjection of the Grx1-roGFP2 biosensor, revealed that oocytes exposed to fluid from women without endometriosis exhibited a more significant reduction (mean change in r/o ratio 0.17, p < 0.001) than those exposed to fluid from women with endometriosis (mean change 0.07, p < 0.001).
