几位研究人员认为，在自然条件下生活的人，在最低限度的卫生条件下，排卵可能不会被隐藏。因为在这样的人群中测量性交频率是有问题的，所以我通过询问坦桑尼亚的哈扎狩猎采集者，间接地验证了这一命题。如果人们(1)知道怀孕是由性引起的，而人们(2)说女性在月经周期中期怀孕，我们可能会推断人们认为女性在月经周期中期怀孕，因为大多数交配发生在那个时候。如果交配在排卵期前后达到高峰，它是不会被隐藏的。哈扎人知道怀孕是由性引起的，但大多数人说月经结束后就怀孕了。因此，Hadza的观念并不表明在更自然的条件下，人类的排卵更容易被检测到。
Several researchers have suggested that ovulation may not be concealed in humans living under natural conditions with minimal hygiene. Because measuring coital frequency in such a population is problematic, I tested this proposition indirectly by asking Hadza hunter-gatherers of Tanzania when a woman can get pregnant. If people (1) know that pregnancy is caused by sex, and people (2) say that women conceive in the middle of the menstrual cycle, we might infer that people think women conceive in the middle of the cycle because most copulations occur then. If copulation peaks strongly around ovulation, it is not concealed. The Hadza know that pregnancy is caused by sex but most say conception occurs right after menstruation ends. Hadza conception beliefs therefore do not suggest that ovulation is more detectable in humans under more natural conditions.
