Male rats castrated and given androstenedione neonatally can show high levels of both masculine and femine copulatory behavior in adulthood. In the present study, intact female and male hamsters castrated at birth were treated for their first 20 days with oil, free testosterone, or androstenedione. All neonatal androgen treatments mimicked the naturally occurring developmental process of the male in that all androgenized groups were capable of high levels of male behavior (males but not females showing ejaculation patterns) as well as moderate levels of lordotic receptivity. There were no significant differences in effect among neonatal androgen treatments. The results were discussed as they relate to species differences, sex differences, hamster "bisexuality," and posthormone copulatory performance.
新生期阉割并给予雄烯二酮的雄性大鼠在成年后可表现出高水平的雄性和雌性交配行为。在本研究中，出生时阉割的完整雌性和雄性仓鼠在出生后的前20天接受油、游离睾酮或雄烯二酮处理。所有新生期雄激素处理都模拟了雄性自然发生的发育过程，因为所有雄激素化组都能够表现出高水平的雄性行为（只有雄性表现出射精模式）以及中等水平的脊柱前凸接受性。新生期雄激素处理之间在效果上没有显著差异。讨论了这些结果与物种差异、性别差异、仓鼠“双性恋”以及激素后交配表现的关系。
