Abstract

Orchidectomized rats were given estrogen and progesterone and tested for feminine behavior in the presence of a mounting male after accessory olfactory bulb removal (AOBR). Complete AOBR caused a rise in the number of estrogen-progesterone-treated male rats responding by lordosis behavior to male mounts as compared to controls and sham-operated animals. By contrast, LQ scores did not appear to differ in these three groups of animals. The results are discussed in terms of involvement of the main and the accessory olfactory systems in the regulation of feminine behavior in the male rat.

摘要

对去势大鼠给予雌激素和孕酮，并在切除副嗅球（AOBR）后，在有正在爬跨的雄性大鼠存在的情况下测试其雌性性行为。与对照组和假手术动物相比，完全切除副嗅球导致接受雌激素-孕酮处理的雄性大鼠中，以脊柱前凸行为对雄性爬跨做出反应的数量增加。相比之下，这三组动物的LQ评分似乎没有差异。根据主嗅觉系统和副嗅觉系统在雄性大鼠雌性性行为调节中的作用对结果进行了讨论。
