[Effect of chronic stress in prepubertal period on sexual arousal in the male rats].

Effects of two models of chronic stress were studied in adult male rats with inherited stress-induced arterial hypertension (ISIAH) and in Wistar rats. Intact males of both rat strains demonstrated a similar behavioural and hormonal activation in sexual arousal. Prepubertal chronic stress decreased the female-induced behavioural response and the effect depended on the character of stress and the animal genotype. No long-lasting effects of pre-pubertal stress on the plasma corticosterone level in males under sexual arousal were observed.
