Previous research has found that women at peak fertility show greater interest in extra-pair sex. However, recent replications have failed to detect this effect. In this study, we add to this ongoing debate by testing whether sociosexuality (the willingness to have sex in the absence of commitment) is higher in women who are at peak fertility. A sample of normally ovulating women ( = 773) completed a measure of sociosexuality and had their current fertility status estimated using the backward counting method. Contrary to our hypothesis, current fertility was unrelated to sociosexual attitudes and desires, even when relationship status was included as a moderator. These findings raise further doubts about the association between fertility and desire for extra-pair sex.
先前的研究发现，生育高峰期的女性对婚外性行为表现出更大的兴趣。然而，最近的重复研究未能检测到这种效果。在这项研究中，我们通过测试生育高峰期女性的性行为开放性（在没有承诺的情况下发生性行为的意愿）是否更高，来加入到这场持续的争论中。我们的样本由正常排卵的女性（=773）组成，她们完成了性行为开放性的测量，并使用回溯计数法估计了她们当前的生育状况。与我们的假设相反，即使将关系状况作为调节变量，当前的生育能力与性行为开放性的态度和欲望也没有关系。这些发现进一步质疑了生育能力与对婚外性行为的渴望之间的关联。
