Evidence suggests that fertility in women is accompanied by increased preferences for male traits that putatively signal underlying genetic quality, adaptive increases in sexual motivation, and changes in attractiveness. Yet, these supposed adaptive shifts remain controversial and disputed, while methods across studies have been inconsistent. In this chapter, we review the research on phenotypic variation across the human menstrual cycle, focusing on the related areas of preferences for male traits, sexual behavior and motivation, and cues to ovulation. Next, we consider the various methods currently used by researchers to ascertain conception risk and review recently published recommendations intended to guide future research and facilitate comparison across studies.

Knowledge of the biological mechanisms involved in human behavior informs evolutionary perspectives on selection pressures in our ancestral past, which encourages the development of more complete theories and more refined research questions. Yet, despite these advances, many unanswered questions remain. This chapter outlines broad suggestions for future hormone research within the topics of development and survival, reproductive behavior, and social and affective behavior. It concludes with several general suggestions for the field, including more research using hormonal assays, longitudinal and experimental designs, exogenous hormone administration, and cross-cultural work. It also suggests that researchers continue to consider the function of other endocrine traits (e.g., carrier proteins) and measure or manipulate hormones in combination with assessing hormone receptor genes.

The likelihood that a single act of intercourse will result in conception is greatest in the days preceding ovulation. At this time, women are more attractive and are more driven to enhance their attractiveness. Androphilic women become more interested in men who are not their primary partner, and their preference for physically and behaviorally feminine men decreases. Because men who are women's primary partners risk desertion or (if their partner engages in short-term sexual relationships with other men) investing in biologically unrelated offspring, they have likely experienced selection pressure to deploy counterstrategies that mitigate the effects of female menstrual cycle shifts. These counterstrategies may include changes to a man's sexual desire, his jealousy and mate-guarding behavior, and his propensity to compete with sexual rivals

The stress response system involves physiological processes in reaction to a real or perceived threat, which serve a variety of purposes. This chapter reviews pertinent topics and research within the social neuroendocrine study of stress, including acute versus chronic stress, and how stress influences social behavior and status. Where appropriate, it offers critiques of current theoretical models and includes suggestions for future directions within this research area.
