Summary
Drugs may interfere with the organizing action of circulating hormones such as gonadal and adrenal steroids on the developing brain and by this mechanism induce long-lasting alterations in brain function. In the rat, prenatal exposure to nicotine on gestational days 12–19 affects sexually dimorphic behavior and causes sex-dependent neurochemical changes. Prenatal nicotine suppresses a characteristic peak of plasma testosterone in the male rat fetus and results in depressed, female-like activity of brain aromatase which converts testosterone to estradiol, at a particular, early postnatal (PN) stage (PN 6).
