Abstract Women's mating psychology may have evolved to track reproductive conditions, including conception risk, across and between ovulatory cycles. Alternatively, within-woman correlations between mating psychology and ovarian hormones may be byproducts of between-women relationships. Here, we examined associations between steroid hormones and two facets of sexual psychology with putatively different adaptive functions, sociosexual orientation and general sexual desire, in a sample of naturally cycling women (NC; n = 348, 87 of whom completed 2 sessions) and hormonally contracepting women (HC; n = 266, 65 of whom completed 2 sessions). Across two sessions, increases in estradiol predicted elevated sociosexual desire in NC women, and this relationship was stronger in women whose progesterone simultaneously decreased across sessions. Changes in hormones were not associated with changes in general sexual desire. Between-subjects differences in testosterone robustly, positively predicted sociosexuality and general sexual desire among NC women. Hormones were not consistently related to changes or differences in sexual psychology among HC women. The present results are consistent with testosterone contributing to individual differences, or modulating relatively long-term changes, in women's mating psychology. Further, our within-woman findings are consistent with the hypothesis that shifts in women's mating psychology may function to secure genetic benefits, and that these shifts are not byproducts of between-women associations.

女性性动机的荷尔蒙预测因子

摘要 女性的交配心理可能已经演变为跟踪排卵周期之间和之间的生殖条件,包括受孕风险。或者,交配心理和卵巢激素之间的女性内部相关性可能是女性之间关系的副产品。在这里,我们在自然骑自行车的女性(NC;n = 348,其中 87 人完成了 2 个疗程)和荷尔蒙的样本中检查了类固醇激素与具有假定不同的适应功能、社会性取向和一般性欲的性心理学的两个方面之间的关联。避孕妇女(HC;n = 266,其中 65 人完成了 2 个疗程)。在两个疗程中,雌二醇的增加预示着 NC 女性的社会性欲提高,而这种关系在孕激素同时降低的女性中更为强烈。激素的变化与一般性欲的变化无关。受试者之间睾丸激素的差异有力地预测了 NC 女性的社会性取向和一般性欲。激素与 HC 女性的性心理变化或差异并非始终相关。目前的结果与睾丸激素在女性交配心理中导致个体差异或调节相对长期变化的结果一致。此外,我们在女性内部的发现与以下假设一致,即女性交配心理的变化可能有助于确保遗传优势,并且这些变化不是女性之间关联的副产品。积极预测 NC 女性的社会性取向和一般性欲。激素与 HC 女性的性心理变化或差异并非始终相关。目前的结果与睾丸激素在女性交配心理中导致个体差异或调节相对长期变化的结果一致。此外,我们在女性内部的发现与以下假设一致,即女性交配心理的变化可能有助于确保遗传优势,并且这些变化不是女性之间关联的副产品。积极预测 NC 女性的社会性取向和一般性欲。激素与 HC 女性的性心理变化或差异并非始终相关。目前的结果与睾丸激素在女性交配心理中导致个体差异或调节相对长期变化的结果一致。此外,我们在女性内部的发现与以下假设一致,即女性交配心理的变化可能有助于确保遗传优势,并且这些变化不是女性之间关联的副产品。或调节女性交配心理的相对长期变化。此外,我们在女性内部的发现与以下假设一致,即女性交配心理的变化可能有助于确保遗传优势,并且这些变化不是女性之间关联的副产品。或调节女性交配心理的相对长期变化。此外,我们在女性内部的发现与以下假设一致,即女性交配心理的变化可能有助于确保遗传优势,并且这些变化不是女性之间关联的副产品。
