Abstract Modern-day environments differ drastically from those in which humans evolved, which likely has important implications for human mating psychology. Particularly notable is the modern advancement of hormonal contraceptives (HCs), which alter the natural hormones of the many women who use them. According to the HC congruency hypothesis, HCs alter sex hormones and brain processes that are linked to numerous relationship preferences. In light of work suggesting such preferences play an important role in relationship evaluations, changing HC use during a long-term relationship (relative to use at relationship formation) should impact women's relationships. We used data from two independent longitudinal studies of 203 newlywed couples to address this possibility. Results demonstrated that wives reported lower sexual satisfaction (but not marital satisfaction) when their HC use was incongruent (versus congruent) with their use at relationship formation. These findings provide preliminary support for the HC congruency hypothesis, though we also broaden our theoretical framework to offer methodological recommendations for future research.

关系形成后改变激素避孕方法的影响

摘要 现代环境与人类进化的环境截然不同，这可能对人类交配心理学具有重要意义。特别值得注意的是激素避孕药 (HC) 的现代进步，它改变了许多使用它们的女性的天然激素。根据 HC 一致性假设，HC 会改变与众多关系偏好相关的性激素和大脑过程。鉴于工作表明这种偏好在关系评估中起着重要作用，在长期关系中改变 HC 的使用（相对于在关系形成时的使用）应该会影响女性的关系。我们使用来自 203 对新婚夫妇的两项独立纵向研究的数据来解决这种可能性。结果表明，当妻子的 HC 使用与其在关系形成中的使用不一致（与一致）时，妻子报告的性满意度（但不是婚姻满意度）较低。这些发现为 HC 一致性假设提供了初步支持，但我们也拓宽了我们的理论框架，为未来的研究提供了方法论建议。
