Alterations in cellular homeostasis that affect protein folding in the. In the presence of chloride ion, H2O2 is converted to hypochlorous acid (HOCl). Finally, while using exogenous antioxidants as a method to counteract the adverse effects of oxidative stress has been proven to be effective for natural pregnancy, randomized, double-blind, prospective, and placebocontrolled studies are still needed to demonstrate their effectiveness in assisted reproductive techniques.
