title: Sexual differentiation of androgen-sensitive and estrogen-sensitive regulatory systems for aggressive behavior.
abstract: CF-1 female mice were treated with either testosterone (T), diethylstilbestrol (DES), or methyltrienolone (R1881) on the day of birth and were subsequently tested for their responsiveness to the aggression-promoting property of androgen or estrogen during adulthood. The results showed that neonatal exposure to androgen enhanced subsequent sensitivity to androgenic stimulation but did not alter responsiveness to estrogens. Neonatal estrogen treatment established the capacity to exhibit aggression in response to estrogenic stimulation in adulthood but had little effect on responsiveness to androgens. These data indicate that the androgenic and estrogenic metabolites of T have distinct roles in masculinization of the neural substrate for aggressive behavior.
