B The proportion of rats with normal estrous cycles at the end of the 3rd and 4th weeks of intragastric administration. The proportion of rats with normal estrous cycles is shown by bar plots. Fisher’s exact test for multiple rates comparisons (*P < 0.05). C Hematoxylin and eosin (H&E) staining of ovarian tissue of the PCOS, BSTJF and control groups. All scale bars are 100 μm. D The pregnancy of PCOS, BSTJF and control groups
