Ovariectomized, estrogen-primed, adult female rhesus macaques were preselected for the display of high (HLP) and low (LLP) levels of sexual performance. Eight sexually vigorous adult males were selected as partners. For 13 consecutive days each month, females received 0, 2.5, 5.0, and 10.0 micrograms of estradiol benzoate (EB) and were tested on Days 12 and 13 of injection. Blood samples were taken before and on the last day of each of the four injection series, and serum levels of estradiol, progesterone, and testosterone were determined with a radioimmunoassay. The HLP females (n = 5) displayed higher levels of receptivity and proceptivity and received more mounts, intromissions, and ejaculations when tested without EB treatment than LLP females (n = 5) did when they were tested with 10.0 micrograms of EB. Female receptivity, proceptivity, and attractiveness cannot be explained by estrogen action alone. The effectiveness of estrogen is limited by the somatic characteristics of the individual on which it acts.
对成年雌性恒河猴进行卵巢切除、雌激素预处理，预先挑选出性行为表现水平高（HLP）和低（LLP）的个体。挑选8只性活力旺盛的成年雄性作为配偶。每月连续13天，雌性接受0、2.5、5.0和10.0微克苯甲酸雌二醇（EB）注射，并在注射的第12天和第13天进行测试。在四个注射系列的每个系列开始前和最后一天采集血样，用放射免疫分析法测定雌二醇、孕酮和睾酮的血清水平。与接受10.0微克EB测试的LLP雌性（n = 5）相比，未接受EB治疗进行测试时，HLP雌性（n = 5）表现出更高水平的接受性和求偶性，且接受了更多的爬跨、插入和射精。雌性的接受性、求偶性和吸引力不能仅用雌激素作用来解释。雌激素的有效性受到其作用个体的躯体特征的限制。
