In 2 independent experiments, we measured and correlated in maturing male Japanese quail the individual variations in sexual and aggressive behavior, cloacal gland size, testes weight, plasma testosterone concentrations and intracellular testosterone metabolism by hypothalamus and cloacal gland. Cloacal gland area was only weakly related to plasma testosterone levels but was positively correlated with the production of active androgenic metabolites and negatively related to the production of 5 beta-reduced androgens (inactive) in the glandular tissue. Several measures of behavior were correlated with aspects of the testosterone metabolism in the anterior hypothalamus. In both experiments, the behavior of the birds was also strongly correlated with their testes weight and their cloacal gland area but weakly or not at all with their plasma testosterone levels. These studies suggest that testosterone metabolism is involved in the control of hormone action in maturing animals.
在两项独立实验中，我们对成熟雄性日本鹌鹑的性行为和攻击行为、泄殖腔腺大小、睾丸重量、血浆睾酮浓度以及下丘脑和泄殖腔腺的细胞内睾酮代谢的个体差异进行了测量和关联分析。泄殖腔腺面积与血浆睾酮水平仅呈弱相关，但与活性雄激素代谢产物的产生呈正相关，与腺组织中5β-还原雄激素（无活性）的产生呈负相关。多项行为指标与下丘脑前部的睾酮代谢情况相关。在两项实验中，鸟类的行为也与其睾丸重量和泄殖腔腺面积密切相关，但与血浆睾酮水平的相关性较弱或根本不相关。这些研究表明，睾酮代谢参与了成熟动物体内激素作用的调控。
