Fructose improves titanium dioxide nanoparticles induced alterations in developmental competence of mouse oocytes.

Aims: We investigated the effects of intraperitoneal injections of titanium dioxide nanoparticles (TiO NPs, 100 mg/kg) for 5 consecutive days on the developmental competence of murine oocytes. Furthermore, study the effects of TiO NPs on antioxidant and oxidative stress biomarkers, as well as their effects on expression of apoptotic and hypoxia inducing factor-1α (HIF1A) protein translation. Moreover, the possible ameliorating effects of intraperitoneal injections of fructose (2.
