Ovarian tissue pathology assessment in mice of each group. a Representative photography by Hematoxylin & Eosin (40 × , 100 × , and 400 ×). The black, blue, red and white arrows indicate primary follicles, secondary follicles, antral follicles and atretic follicles respectively. b follicle counting. PF: primordial follicle; PrF: primary follicles; SF: secondary follicles; AnF: antral follicles; AF: atretic follicles. All data are expression as mean ± standard deviation mean (‾x ± SD) (n = 6). ^★P < 0.05 and ^★★P < 0.01 compared with the CTX group; ^▲P < 0.05 and ^▲▲P < 0.01 compared with the Con group
