[237] found that EGCG acts mainly by regulating ROS (reactive oxygen species) levels, which affect the expression of CAT, superoxide dismutase 1 (SOD1), superoxide dismutase 2 (SOD2) and glutathione peroxidase, which delays germ cell and oocyte infertility. The gene discussed is SOD1; the disease is Infertility.
