在雌性大鼠的伴侣偏好测试中使用的刺激动物各不相同。为了检验替代刺激动物调节对完整雄性的偏好这一假设，性腺切除（GDX）雌性大鼠接受苯甲酸雌二醇加孕酮或油溶剂，并测试与GDX雌激素致敏雌性配对的完整雄性或与GDX雄性配对的完整雄性的伴侣偏好。在限制身体接触（无接触）或允许性互动（接触）的条件下对大鼠进行测试。刺激动物的条件是不是一个主要的决定因素的合作伙伴的偏好。相比之下，接触条件和激素治疗调制的偏好，以及活动水平和显示的接受行为。我们的研究结果表明，在这里测试的替代刺激动物的特性不发挥重要作用，在调节伴侣偏好的雌性大鼠。
The stimulus animals used in tests of partner preference in female rats vary. To test the hypothesis that the alternative stimulus animal modulates the preference for an intact male, gonadectomized (GDX) female rats received estradiol benzoate plus progesterone or the oil vehicle and were tested for partner preference with either an intact male paired with a GDX hormone-primed female or an intact male paired with a GDX male. Rats were tested under conditions that limited physical contact (No Contact) or allowed sexual interaction (Contact). Stimulus animal condition was not a primary determinant of partner preference. In contrast, contact condition and hormone treatment modulated preference, as well as activity levels and the display of proceptive behaviors. Our findings demonstrate that the characteristics of the alternative stimulus animals tested here do not play a significant role in modulating partner preference in female rats.
