1 Our previous studies have revealed that single oral administration of TCDD (1 jg/kg) to pregnant rats at gestational day (GD) 15 attenuates the fetal expression of testicular steroidogenic proteins such as steroidogenic acute-regulatory protein (StAR) and cytochrome P450 (CYP) 17 by targeting the fetal production of pituitary gonadotropins.

3 When pregnant Wistar rats were orally treated with TCDD, the fetal expression of CYP21, CYP11B1 and CYP11B2 mRNAs was either induced or tended to be induced in the male adrenal gland during GD17 and GD19, while the expression of mRNAs coding for StAR, CYP11A1 and 313-hydroxysteroid dehydrogenase was insensitive to TCDD treatment.
