Decidualization is important for embryo implantation and placenta formation. Abnormal decidualization can cause infertility. Our study focuses on the anti-oxidative stress mechanism during decidualization, involving the glutathione antioxidant system. Glucose metabolism and the enzyme G6PD play a crucial role in this process. Inhibiting glutathione synthesis or G6PD impairs decidualization. Targeting these processes may be a new treatment for infertility.
