女性女性安装是广泛存在于哺乳动物物种，但很少有人知道这种行为的近端功能。虽然这种安装通常被认为是一个'男性'的特点，它的广泛发生可能表明，它服务于特定的功能范围内的女性-女性的社会行为。我们在标准观察室和自然围栏中评价了Long-Evans大鼠的雌性坐骑行为。在这些条件下，我们研究了一些潜在的因素，可能会影响安装，包括发情周期，社会阶层，熟悉和男性的存在。雌性的安装不受她自己的发情周期，但不同的发情周期的刺激女性。社会上占主导地位的女性安装显着超过下属的女性，安装由占主导地位的女性是最常见的下属女性时，性接受。女性安装（和战斗）不熟悉的女性显着比他们熟悉的笼。当有雄性存在时，雌性-雌性的交配数量急剧减少。进一步的测试表明，女性安装并不影响怀孕的孕前期状态的诱导，这表明女性安装不作为一个pseudomale行为，可以替代男性提供的生殖器刺激。根据这些数据，女性骑跨本身似乎不是一种性行为，而是一种女性社会行为，与女性群体中女性的社会地位有关。在这方面，本研究的结果表明，女性安装是正常女性的复杂的行为剧目的一部分，并不一定反映一些潜在的神经基板的男性化。(C)1999年，动物行为研究协会。
Female-female mounting is widespread among mammalian species, but little is known about the proximal function of this behaviour. While such mounting is often regarded as a 'masculine' trait, its widespread occurrence may indicate that it serves specific functions within the context of female-female social behaviour. We valuated female mounting behaviour in Long-Evans rats in standard observation chambers and in a seminatural enclosure. Under these conditions, we examined a number of potential factors that might influence mounting, including the oestrous cycle, social hierarchy, familiarity and male presence. The female's mounting was not influenced by her own oestrous cycle, but did vary with the oestrous cycle of the stimulus female. Socially dominant females mounted significantly more than subordinate females, and mounting by the dominant female was most frequent when the subordinate female was sexually receptive. Females mounted (and fought with) unfamiliar females significantly more than they did with familiar cagemates. Female-female mounting was dramatically reduced when males were present. Further testing showed that female mounting did not affect the induction of the progestational state of pregnancy, suggesting that female mounting does not function as a pseudomale behaviour that can substitute for genital stimulation provided by the male. Based on these data, female mounting does not appear to function as a sexual behaviour per se, but may serve as a form of female social behaviour related to maintenance of the female's social status within female groups. In this regard, the results of this study suggest that female mounting is part of the normal female's complex behavioural repertoire and does not necessarily reflect masculinization of some underlying neural substrate.
