Age-dependent gene expression changes in fetal ovarian steroidogenic enzymes (top 3 panels) between day 65 (left graph) and day 90 (right graph) of gestation in control (C; open bars) and BPA-treated (closed bars) females. Results for 3β1HSD, 3β2HSD, and 17βHSD of control and BPA-treated females were combined for testing age effects when there was no treatment effect within age. Treatment effects were observed only with Cyp19 and 5α-reductase expression (2 bottom panels). Asterisks represent statistical differences between ages (P < .005) or treatment groups. Control (n = 4 and 5, respectively, at day 65 and day 90) and prenatal BPA-treated (n = 5, both ages) groups.
