Estrous cycle

... some evidence suggests human females also undergo semi-annual heat cycles. Although sexual responsiveness is influenced by social and cultural factors, there is evidence that human females undergo emotional and physiological changes associated with estrus cycles and may be more likely to be irritable and/or sexually aroused during the peaks of heat cycles. Further, just as males of other species respond in differing ways to females in heat, human males respond to the "call" of human females in estrus.
