女性之所以隐蔽排卵期,拥有各种假说进行解释,例如:父方投资假说、减少杀婴假说、社会联系假说、性奖励假说、通奸假说。 虽然演化过程中,这些假说提到的内容,都有足于女性“隐蔽”排卵期。但从生理特征上来解释,应该更加接近真相。 包括类人猿在内的雌性哺乳动物往往在发情期通过肿胀的外阴来吸引雄性,但人直立行走之后,视野脱离外阴。女性的外阴信号不仅越来越无用,而且还会影响行走。早期人类社会,在恶劣环境中形成选择压力,令隐蔽发情期的女性被选择了出来。[7]

It is not implausible that, with natural selection refining their diagnostic skills, females could glean all sorts of clues about a male's health, and the robustness of his ability to cope with stress, from the tone and bearing of his penis.
