Selective activation of androgen receptors in the subcortical brain of male cynomolgus macaques by physiological hormone levels and its relationship to androgen-dependent aromatase activity

Aromatase activity (AA) is androgen dependent and independent in subcortical regions of the nonhuman primate brain, but the correlation of androgen receptor (AR) content with AA has not been demonstrated. Thus, we castrated 10 adult male cynomolgus monkeys (Macaca fascicularis) and divided them into 2 groups. One group (n = 6) received empty Silastic capsules, whereas the second group (n = 4) rece…
