Fig. 2From: Synergistic effect of Huyang Yangkun Formula and embryonic stem cells on 4-vinylcyclohexene diepoxide induced premature ovarian insufficiency in miceThe POI model of mice was created successfully. a Estrus cycle monitoring: a.proestrus b.estrus c.postestrus d.diestrus. b The estrus cycle of most mice disordered after modeling. c Changes in ovarian morphology before and after modeling. Ovaries in CON group and ovaries in MOD group were shown as presented. d The numbers of follicles at all levels was decreased in the MOD group compared with the CON groupBack to article page
