Figure 1. (A) shows ovarian tissue in the control group. In this group, more coherence was seen in the tissue than in other groups. (B) shows the H&E staining in the vitrification group and the primordial follicles can be seen. Also, tissue cohesion due to the vitrification and staining steps is less than in the control group. (C) indicates tissue incoherence, and primary follicles were seen in this group. (D) reveals the incoherence of primary and secondary tissues and Graafian follicles.
