为了弄清在人类进化过程中是否真的“失去了发情”(正如研究人员经常声称的那样)，我们研究了在男士俱乐部工作的专业大腿舞者的排卵周期对小费收入的影响。18名舞者在一项研究网站上记录了她们60天的月经周期、工作班次和小费收入。一项对296个轮班(代表约5300个膝舞)的混合模型分析表明，周期阶段和激素避孕使用之间存在交互作用。正常情况下，自行车参与者在发情期每5小时轮班赚335美元，在黄体期每班赚260美元，在月经期每班赚185美元。相比之下，使用避孕药的参与者没有表现出发情期收入峰值。这些结果构成了第一个直接的经济证据，证明了发情在当代人类女性中的存在和重要性，在现实世界的工作环境中。这些结果对人类进化、性行为和经济学都有明显的影响。(C)2007 Elsevier Inc.保留所有权利。
To see whether estrus was really "lost" during human evolution (as researchers often claim), we examined ovulatory cycle effects on tip earnings by professional lap dancers working in gentlemen's clubs. Eighteen dancers recorded their menstrual periods, work shifts, and tip earnings for 60 days on a study web site. A mixed-model analysis of 296 work shifts (representing about 5300 lap dances) showed an interaction between cycle phase and hormonal contraception use. Normally cycling participants earned about US$335 per 5-h shift during estrus, US$260 per shift during the luteal phase, and US$185 per shift during menstruation. By contrast, participants using contraceptive pills showed no estrous earnings peak. These results constitute the first direct economic evidence for the existence and importance of estrus in contemporary human females, in a real-world work setting. These results have clear implications for human evolution, sexuality, and economics. (C) 2007 Elsevier Inc. All rights reserved.
