Graphene oxide (GO) and Fe3O4 super paramagnetic material are good candidate for some applications such as drug delivery. It has been shown that combining Fe3O4 with graphene oxide increases the biological efficiency of GO. The use of novel assisted reproductive technologies such as gonadotropins injection has been able to help the fertility of infertile people, but the side effects of these methods and high costs are still problems. The aim of the present study was to investigate the effect of magnetic graphene oxide (MGO) on the in vivo maturation of mouse oocytes. Thirty 6–8-week old female Naval Medical Research Institute (NMRI) mice were treated with intra peritoneal (I.P) injection of MGO mixed with hormones. 12 h after I.P. injection of MGO mixed with PMSG and HCG, the number of metaphase II (MII) oocytes obtained from the left fallopian tubes was counted in each group. Also, immuno-cytochemical staining of glutathione and morphometric analysis of ovaries were studied. The results of this study showed that the simultaneous use of MGO, pregnant mare serum gonadotropin (PMSG), and human chorionic gonadotrophin (HCG) increases the number of MII oocytes and helps to increase maturation of oocytes. It could be concluded that MGO can increase the efficiency of super ovulating hormones due to increase in adsorption of serum hormones and growth factors.
