Previous research demonstrated a relationship between the temporal pattern of heterosexual activity and an index of ovarian functioning. In the current study, this relationship was investigated in 147 menstruating heterosexual women (aged 19-53). They kept prospective daily records of menses, basal body temperature, sexual activity, and other behaviors for three consecutive menstrual cycles. In contrast to previous findings, women with intermediate levels of sexual activity displayed more frequent optimal menstrual cycles. Pheromones, semen absorption, and orgasm-related changes were tested as mediators for a causal influence of sexual activity on ovarian functioning; none was supported. Exploratory analyses tested the hypothesis that anovulatory cycles (with presumably lower progesterone) would display more sexual activity than ovulatory cycles. This hypothesis was supported, and the difference in sexual activity was limited to the second half of the cycle, after ovulation would have occurred. Thus, the findings incorporate temporal precedence of ovulation to support the idea that physiological processes influence the level of sexual activity in heterosexual women.
先前的研究表明异性恋活动的时间模式与卵巢功能指标之间存在关联。在当前的研究中，对147名处于月经期的异性恋女性（年龄在19至53岁之间）进行了此项关联调查。她们连续三个月经周期前瞻性地每日记录月经情况、基础体温、性活动及其他行为。与先前的研究结果相反，性活动水平处于中等的女性表现出更频繁的最佳月经周期。对信息素、精液吸收以及与性高潮相关的变化作为性活动对卵巢功能产生因果影响的中介因素进行了测试；但均未得到证实。探索性分析检验了如下假设：无排卵周期（推测孕酮水平较低）相比有排卵周期会表现出更多的性活动。这一假设得到了证实，并且性活动的差异仅限于排卵后周期的后半段。因此，这些研究结果纳入了排卵的时间先后顺序，以支持生理过程影响异性恋女性性活动水平这一观点。
