Estrogen and progesterone contents and ERα expression level in cultured D10 follicles. (A) The secretion levels of estrogen by D10 follicles (ng/L). (B) The secretion levels of progesterone by D10 follicles (ng/ml). (C) The expression levels of ERα in D10 follicular granulosa cells were detected with Western blot analysis. Compared with control, ^aP < 0.05; and compared with BPA group, ^bP < 0.05.
