Oppositely sexed pairs of gorillas were tested behaviorally during the menstrual cycle to determine the relationship between hormone concentrations of the female and the frequency of sexual activity by the pair. Five females were tested individually during two cycles with each of two males, but serum samples for hormone assay were obtained from each female only during the first cycle of testing. There was no clear relationship between hormones and behavior for the single cycle in which the serum samples were obtained, with the exception that no copulations occurred after the early luteal phase, when progesterone was greater than 5 ng/ml. Normalized behavioral data from all four test cycles for all pairs suggested that female-solicited copulations were restricted primarily to the periovulatory period. Male sexual initiative (by one of the males) accounted for most copulations temporally dissociated from the periovulatory period. Normalized hormone data for all of the females suggested that (1) attractivity was associated with estradiol concentrations during the follicular phase, (2) proceptivity with estradiol and testosterone at midcycle, whereas (3) receptivity was not associated with hormone patterns or cycle phase. The data suggest that hormones are one of several variables that contribute to the regulation of sexual behavior in gorillas.
在月经周期中，对性别相反的大猩猩配对进行行为测试，以确定雌性激素浓度与配对中性行为频率之间的关系。五只雌性大猩猩在两个周期内分别与两只雄性大猩猩中的每一只进行测试，但仅在第一个测试周期从每只雌性大猩猩获取用于激素检测的血清样本。在所获取血清样本的单个周期中，激素与行为之间没有明确的关系，唯一的例外是在黄体期早期之后没有发生交配，此时孕酮大于5纳克/毫升。所有配对的四个测试周期的标准化行为数据表明，雌性主动要求的交配主要限于排卵期前后。雄性的性主动行为（由其中一只雄性发起）占大多数与排卵期前后时间上不相关的交配。所有雌性大猩猩的标准化激素数据表明：（1）在卵泡期，吸引力与雌二醇浓度有关；（2）在周期中期，性接受倾向与雌二醇和睾酮有关，而（3）接受性与激素模式或周期阶段无关。数据表明，激素是影响大猩猩性行为调节的几个变量之一。
