The temporal and dynamic characteristics (duration, frequency, rhythmicity, and vigor) of pelvic thrusting displayed by 17 male golden hamsters during their copulatory behavioral responses: mounts, intromissions, ejaculations, and long intromissions, as well as their temporal correlation with the genital contacts established by intravaginal penile insertion, were studied by an accelerometric and polygraphic technique. Pelvic thrusting in all copulatory behavioral responses appeared as series or trains of rhythmical, synchronic, vigorous movements. The various pelvic thrusting trains lasted around 1 s on average, but those of mounts were significantly longer than the trains displayed in the other behavioral responses. The frequencies of pelvic thrusting were similar in all responses (around 15 thrusts per s) excepting mounts which had lower values. In intromission, ejaculation, and long intromission responses, when penile insertion occurred, pelvic thrusting either was interrupted or showed changes in its characteristics: penile insertion was related to a period without thrusting in intromissions, to a series of intravaginal thrusting of higher frequency (16.4 thrusts per s) and lower vigor in ejaculations, and to a prolonged period of 6 to 25 s of slow intravaginal pelvic thrusting (1-2 thrusts per s) in long intromissions. Penile insertion lasted longer in ejaculations than in intromissions and it was significantly shorter in both of these responses than in long intromissions. These results provide information about some dynamic aspects of sexual behavior in hamsters, as well as a temporal correlation between the motor and genital components of this behavior.
通过加速度测量和多导记录技术，研究了17只雄性金黄地鼠在交配行为反应（爬跨、插入、射精和长时间插入）中所表现出的骨盆推顶的时间和动态特征（持续时间、频率、节律性和力度），以及它们与通过阴茎插入阴道所建立的生殖器接触的时间相关性。在所有交配行为反应中，骨盆推顶均表现为有节奏、同步、有力的运动系列或序列。各种骨盆推顶序列平均持续约1秒，但爬跨时的序列明显长于其他行为反应中的序列。除爬跨时频率较低外，所有反应中骨盆推顶的频率相似（约每秒15次推顶）。在插入、射精和长时间插入反应中，当阴茎插入时，骨盆推顶要么中断，要么其特征发生变化：阴茎插入在插入反应中与一段无推顶期相关，在射精反应中与一系列频率较高（每秒16.4次推顶）且力度较低的阴道内推顶相关，在长时间插入反应中与一段持续6至25秒的缓慢阴道内骨盆推顶（每秒1 - 2次推顶）相关。阴茎插入在射精反应中的持续时间长于插入反应，且在这两种反应中的持续时间均明显短于长时间插入反应。这些结果提供了有关地鼠性行为一些动态方面的信息，以及这种行为的运动和生殖器成分之间的时间相关性。
