Figure 1.
Serological and histological identification of the PNA mice and the control mice. (A) Determination of the proportion of estrus (the proportion of estrus data multiply by 100 to ensure the height of the ordinate with no change of P value), serum testosterone (nmol/L), and number of secondary follicles in PNA mice and the control mice (**P<0.01, ***P<0.001). (B) Ovarian section in HE staining of the control mice. (C) Ovarian section in HE staining of PNA mice, the original follicles were marked by the arrows. PNA, prenatally androgenized; HE, hematoxylin-eosin.
