Research conducted by the American Psychological Association (APA) highlights how hormones affect love and desire. Its studies reveal that during a woman's fertile ovulation she is more likely to seek out a confident, controlling man for sex. When she is not ovulating, the same woman may seek a kinder, more nurturing man. The APA explains that this behavior is a subconscious way of seeking out more powerful, masculine genes for women to pass on to their children. APA studies show an increase in women dressing more provocatively during ovulation to attract the opposite sex.
Though most commonly associated with women, men are not exempt from the effect of hormones on behavior, according to the APA.
