Characteristics of behavior and stress reactivity of the hypophyseal-adrenocortical system in rats with prenatal inhibition of testosterone metabolism

The effects of administration of the aromatase blocker 1,4,6-androstatrien-3,17-dione (ATD) to female rats in the last third of pregnancy on the stress reactivity of the hypophyseal-adrenocortical system (HACS), behavior in a novel environment (an open field), and anxiety in an elevated cross maze in their adult offspring of both genders were studied. Inhibition of testosterone aromatization in the brain during the prenatal period of development was found to lead to a decrease in the basal activity of the HACS in males and longer-lasting hormonal stress responses in animals of both genders. However, the intergender differences in the nature of the stress reactivity of the system in the experimental animals persisted. Prenatal administration of ATD also induced increases in the levels of anxiety and emotionality and the duration of grooming reactions in males and females and eliminated intergender differences between control males and experimental females in terms of measures of behavior in a new environment such as movement activity, duration of the freezing reaction, and grooming. These data led to the conclusion that impaired testosterone metabolism in the brain during the prenatal period of development induced by administration of the aromatase blocker leads to changes in the nature of the stress response of the HACS in adult male and female rats and impairs the formation of sexual dimorphism in anxiety levels and the extent of behavioral reactions to environmental novelty in females. __________ Translated from Rossiiskii Fiziologicheskii Zhurnal imeni I.
