成年雄性日本鹌鹑由长日照转为短日照。血浆睾酮和二氢睾酮迅速下降，这种内分泌反应随后导致泄殖腔腺（雄激素靶器官）的退化。大约一个月后，在一些但不是所有的鸟类中观察到性腺活动的自发恢复。它与昼夜节律系统的明显变化无关。讨论了这种自发恢复的生理基础以及血浆睾酮和泄殖腔腺大小之间的详细关系。
Adult male Japanese quail were transferred from long to short days. Plasma testosterone and dihydrotestosterone quickly decreased and this endocrine response was followed by a regression of the cloacal gland, an androgen-target organ. After about a month, a spontaneous recovery of gonadal activity was observed in some but not all birds. It was not associated with obvious shifts in the circadian system. The physiological bases of this spontaneous recovery are discussed as well as the detailed relationships between plasma testosterone and cloacal gland size.
