Four adult male rhesus monkeys were provided access individually to a group of receptive females. Each male assumed dominance and engaged in frequent copulations. Plasma testosterone levels increased two- to threefold during this period. Next, each male was subjected to sudden and decisive defeat by a large all-male group, and plasma testosterone fell following this experience. Two males were later reintroduced to the females, and plasma testosterone rose rapidly to the previous elevated levels.
四只成年雄性恒河猴被分别给予接近一群处于发情期雌性的机会。每只雄性都占据主导地位并频繁交配。在此期间，血浆睾酮水平增加了两到三倍。接下来，每只雄性都被一个大型全雄性群体突然决定性击败，经历此事后血浆睾酮水平下降。后来，两只雄性被重新引入雌性群体中，血浆睾酮迅速上升至先前的升高水平。
