The lordosis response was regularly elicited from 24 of 31 intact, adult male hamsters, using manual somatosensory stimulation of the dorsal rear body. In these males there was no correlation between measures of male-typical behavior and lordosis. Castration had no effect on male lordosis duration scores even when intromissions were eliminated. Combined treatment with estradiol benzoate and progesterone significantly increased male lordosis duration scores. The body surface was mapped with a standardized brush stimulus. For eliciting lordosis, effectiveness of stimulation increased in an almost identical manner for hormone-primed males and females from the anterior to the posterior part of the body, with the stimulation of flanks, rump, and perineum the most effective. Within each skin zone, absolute effectiveness was greater in females than in males. Various types of somato-sensory stimulation were compared for their effectiveness in eliciting lordosis. Females were more responsive to these stimuli than males, even when males were hormonally primed. These behavioral data have implications for concepts of the neural organization of male- and female-typical mating responses existing within the same individual.
通过对31只完整成年雄性仓鼠的背部身体进行手动体感刺激，有规律地诱发了其中24只仓鼠的脊柱前凸反应。在这些雄性仓鼠中，雄性典型行为指标与脊柱前凸之间没有相关性。即使消除了插入行为，去势对雄性脊柱前凸持续时间评分也没有影响。苯甲酸雌二醇和孕酮联合治疗显著提高了雄性脊柱前凸持续时间评分。用标准化的刷子刺激对体表进行映射。为了诱发脊柱前凸，对于激素预处理的雄性和雌性仓鼠，从身体前部到后部，刺激的有效性以几乎相同的方式增加，刺激胁腹、臀部和会阴最为有效。在每个皮肤区域内，雌性的绝对有效性高于雄性。比较了各种类型的体感刺激诱发脊柱前凸的有效性。即使雄性经过激素预处理，雌性对这些刺激的反应也比雄性更敏感。这些行为数据对同一动物体内存在的雄性和雌性典型交配反应的神经组织概念具有启示意义。
