Memory, mood, and hormone levels were measured in 25 women during the menstrual and luteal phases of their cycles. Significantly lower visual memory (delayed recall) scores were found during the menstrual phase compared to the luteal phase. No phase differences were found on mood measures or on other memory measures including digit span, paired-associate learning, immediate recall of visual material, and immediate or delayed paragraph recall. The visual memory decrease was most prominent in approximately one-half of the sample and was significantly correlated with plasma progesterone in the luteal phase. For all subjects, paragraph recall scores were negatively correlated with free testosterone levels, whereas paired-associate learning was positively correlated with estradiol levels in the luteal phase. These results suggest that changes in memory test performance may be associated with sex steroid levels, particularly in some subgroups of women.
研究人员在25名女性月经周期的月经期和黄体期测量了她们的记忆力、情绪和激素水平。结果发现，与黄体期相比，月经期的视觉记忆（延迟回忆）得分显著更低。在情绪测量或其他记忆测量方面，包括数字广度、配对联想学习、视觉材料的即时回忆以及段落的即时或延迟回忆，均未发现不同阶段存在差异。视觉记忆下降在大约一半的样本中最为明显，并且与黄体期的血浆孕酮显著相关。对于所有受试者，段落回忆得分与游离睾酮水平呈负相关，而配对联想学习与黄体期的雌二醇水平呈正相关。这些结果表明，记忆测试表现的变化可能与性类固醇水平有关，尤其是在某些女性亚组中。
