The influence of Estradiol benzoate (EB), Testosterone propionate (TP) and Progesterone (P) on the female's partner preference for sexually active males was investigated and compared to levels of receptive and proceptive behaviors observed in a tethered male test situation. Doses of EB (1 micrograms), TP (500 micrograms) and P were selected on the basis of previous investigations indicating that female rats treated with these dosages will show comparable levels of lordosis behavior. The results indicate that TP stimulates partner preference for sexually active males over estrous females in ovariectomized female rats. Females treated with EB tended to prefer the company of sexually active males more than Oil-treated females and less and TP-treated females. However, preference behavior of EB-treated females was not significantly different from that of Oil- or TP-treated females. Additional treatment with P (100 micrograms) did not influence partner preference of Oil-, EB- or TP-treated females. In the tethered male tests, P stimulated proceptivity of EB- or TP-treated females and receptivity of EB-treated females. Significant differences in proceptive and receptive behaviors between EB- or TP-treated were not found. Although facilitation of receptive and in particular, proceptive behaviors were found to be generally accompanied by an increased partner preference for males, it is concluded that gonadal hormones are differentially affecting aspects of female rat sexuality: Relative to the activation of receptive behavior, TP was found to be more effective (than EB) to increase preference for a male; P (given to EB- or TP-treated females) was found to stimulate receptive and proceptive behaviors considerably, while being ineffective to stimulate preference for a male.
研究了苯甲酸雌二醇（EB）、丙酸睾酮（TP）和孕酮（P）对雌性动物对性活跃雄性伴侣偏好的影响，并与在束缚雄性测试情境中观察到的接受和求偶行为水平进行了比较。根据先前的研究选择了EB（1微克）、TP（500微克）和P的剂量，这些研究表明用这些剂量处理的雌性大鼠将表现出相当水平的脊柱前凸行为。结果表明，TP刺激去卵巢雌性大鼠对性活跃雄性而非发情雌性的伴侣偏好。用EB处理的雌性比用油处理的雌性更倾向于选择性活跃雄性的陪伴，但比用TP处理的雌性少。然而，用EB处理的雌性的偏好行为与用油或TP处理的雌性没有显著差异。额外给予P（100微克）并不影响用油、EB或TP处理的雌性的伴侣偏好。在束缚雄性测试中，P刺激了用EB或TP处理的雌性的求偶行为以及用EB处理的雌性的接受行为。未发现用EB或TP处理的雌性在求偶和接受行为上有显著差异。尽管发现接受行为尤其是求偶行为的促进通常伴随着对雄性伴侣偏好的增加，但得出的结论是，性腺激素对雌性大鼠性行为的各个方面有不同影响：相对于接受行为的激活，发现TP（比EB）在增加对雄性的偏好方面更有效；（给予用EB或TP处理的雌性）P被发现能显著刺激接受和求偶行为，而在刺激对雄性的偏好方面无效。
