The existence of ovulatory cycle shifts in human mating psychology and their function for reproduction have been subject to a long-standing debate. Past research has provided initial evidence that women experience distinct shifts in their mating psychology during their fertile window and further suggested evolved counteradaptations in men’s mating psychology as well. However, widespread methodological shortcomings in study design, sample size and analytical flexibility restrict the informational value of most of these studies. Using data from two large, preregistered diary studies, I sought to address these methodological shortcomings and thereby advance our understanding of the nature and function of ovulatory cycle shifts in human mating psychology with my three complementing manuscripts. In Manuscript 1, my co-authors and I found that women experienced several ovulatory increases in their self-perceived attractiveness and related constructs that had not been reported before. In Manuscript 2, we found that women also experienced robust ovulatory increases in their sexual motivation and behaviour as well as concurrent ovulatory decreases in their food intake. In Manuscript 3, we found that male partners of those women analysed in Manuscript 2 did neither perceive cues to women’s fertility status nor showed increased mate retention tactics to secure access to their fertile partners. In the face of current debates about ovulatory cycle shifts, my dissertation provides empirical support for a possible adaptive shift in motivational priorities regarding sex and food in women. Results further question the validity of theoretical predictions of counteradaptations to women’s fertile phase in men. While I stress the need for further theoretical and empirical work, one possible implication of this dissertation is that women might have retained an oestrus-like sexual phase which is not necessarily linked to perceptible cues to fertility. Thus, my dissertation advances the scientific discourse while easing the tension between research on ovulatory cycle shifts and evolutionary theories based on concealment of women’s fertility status.
