The effect of TEAS on irradiation-induced follicle count and ovarian morphology. a The numbers of primordial, primary, secondary, and antral follicles in each group from the ovary with H&E staining (n = 10/group). b Histological examinations of ovaries in each group were analyzed by H&E staining. White arrows: primordial follicles, black arrows: primary follicles. The data represent the mean ± SEM. ** P < 0.01 vs. control- group; ## P < 0.01 vs. IR 2D- group. A white arrow shows the primordial follicles, and a black arrow shows the primary follicles. The scale bars represent 80 μm (first line), 20 μm (second line), and 10 μm (third line)
