Scanning electron micrographs (SEM) of mature oocytes after being denuded and assigned to either the control or experimental groups. (A) is a control mouse oocyte with a normal round shape and size; (B) oocytes from mice treated with 100 mg/kg TiO₂Nps i/p have damage to their surface causing loss of round shape and becoming atretic; and (C) exposure of mouse oocytes to 2.75 mM retain a more regular morphology following exposure to toxic effects of TiO₂ NPs (100 mg/kg)
