Intrahypothalamic implantation of oestradiol and dihydrotestosterone rapidly restored sexual behaviour in castrated, sexually inactive Anolis carolinensis. Implants in areas other than the anterior hypothalamus-preoptic area failed to elicit sexual behaviour. Male aggressive behaviour was unaffected by intracranial hormone implants. Histological examination of the renal sex segment, a secondary sex structure, gave no indication of leakage into the peripheral plasma. The effectiveness of oestradiol and dihydrotestosterone in inducing male courtship behaviour when administered intracranially was compared with the relative ineffectiveness of systemic injections of these hormones.
在下丘脑内植入雌二醇和双氢睾酮能迅速恢复阉割后失去性行为的卡罗来纳安乐蜥的性行为。在前下丘脑-视前区以外的区域植入未能引发性行为。雄性攻击行为不受颅内激素植入的影响。对作为第二性征结构的肾性节进行组织学检查，未发现有激素泄漏到外周血浆中的迹象。将颅内注射雌二醇和双氢睾酮诱导雄性求偶行为的有效性与这些激素全身注射时相对无效的情况进行了比较。
