Men being treated for prostate cancer (PCa) commonly report a diminished sense of their masculinity, but it is not clear what contributes to that perception. Here we examined the literature to explore the characteristics most commonly used to describe diminished masculinity in PCa patients. Data were extracted from 42 peer-reviewed articles that referenced both PCa and terms associated with masculinity. We then ranked the terms by frequency and evaluated whether each reflected a biological feature (e.g., ability to achieve an erection) or a social norm (e.g., being a protector/breadwinner). We also recorded whether patient reports were self-generated or elicited through existing psychological assessment instruments chosen by researchers. We found notable differences between what patients perceived as a decline in their masculinity when spontaneously self-reported, and when elicited through preexisting measures. Patients most often reported changes in bodily function (e.g., reduced erectile function, libido, and physical strength), whereas their responses on formalized measures reflected social and psychological concepts (e.g., self-reliance and stoicism). Our results suggest that loss of masculinity experienced by PCa patients is largely experienced biologically as opposed to socially. Moving forward, interdisciplinary collaboration between those in biomedicine and psychosocial fields will be crucial for improving the quality of life of PCa patients.
Both facial width-to-height ratio (fWHR) and body mass index (BMI) have been associated with aggressive behavior in women but how they influence perception of their potential threat remain unclear. Here, we assessed the effects of fWHR and BMI on perceived formidability from faces of 42 female Ultimate Fighting Championship (UFC) fighters. In study 1, BMI, but not fWHR, positively predicted participants' ratings of aggressiveness and fighting ability from facial photographs. In study 2, both high fWHR and high BMI composite faces were rated as more aggressive, tougher, and more likely to win a fight than low fWHR and low BMI composite faces, respectively. Further analyses revealed that the high BMI composite face was rated as more aggressive and tougher than the high fWHR composite face. Taken together, these results suggest that compared to fWHR, BMI may be a more salient cue to women's formidability.
Several lines of evidence suggest that facial-width-to-height ratio (fWHR) provides an accurate cue to men's formidability, thus providing observers with a reliable estimate of their potential success in an interpersonal physical conflict. The degree to which fWHR provides the same information in women's faces, however, remains unclear. In fact, morphological characteristics, such as body size, may be more effective indicators of formidability in women. In the present study, we analyzed the effects of both fWHR and body mass index (BMI) on total number of fights and total number of wins in female competitive Ultimate Fighting Challenge (UFC) fighters. After controlling for number of active years fighting, we found that BMI significantly predicted number of wins in female fighters. The effects of fWHR were not significant, but warrant replication with a larger sample. These results suggest that in women, body size, rather than fWHR, may be a more accurate indicator of success in aggressive interpersonal conflicts. Our findings contribute to a growing body of literature that shows distinct differences in men and women's interpersonal aggressive and dominance behavior, as well as their morphological indicators.
Previous research has identified physical and behavioral differences between parents who produce sons and those who produce daughters. However, the possibility that men and women have predictions about the sexes of their offspring based on these differences, or any other interoceptive cues, has not been investigated. We compared the dominance, sociosexual orientation, estradiol, testosterone, and 2D:4D ratios of men and women who predicted they would conceive a boy as their first child with those who predicted a girl. Women who predicted they would have a boy were more dominant and less sociosexually restricted than those who predicted they would have a girl. Men who predicted they would have a girl had higher salivary estradiol and higher (more feminine) 2D:4D ratios than those who predicted they would have a boy. Possible implications of these results are discussed in the context of evolutionary theory.
IntroductionTestosterone is known to regulate male sexual interest, but the exact way that androgens influence men's sexual cognition remains unclear.AimTo investigate the influence of androgen deprivation (AD) on visual responses to sexually suggestive stimuli in men treated for prostate cancer with AD therapy.MethodsPatients with AD-treated prostate cancer, patients with prostate cancer not on AD therapy, and age-matched healthy control participants were exposed to images of male and female runway models fully or minimally clothed. Eye tracking was used to compare looking behavior among groups.Main Outcome MeasuresProportion of fixations on fully clothed vs minimally clothed models and proportion of fixations on target areas of interest (ie, legs, chest, pelvis, and face) of fully clothed and minimally clothed models were analyzed and compared among groups.ResultsAlthough men not on AD exhibited a larger proportion of fixations on the minimally clothed compared with the fully clothed images, there was no difference between the 2 image types for men on AD. This was true regardless of whether the images depicted male or female models. Groups did not differ in their fixations to target areas of interest.ConclusionThese results suggest that testosterone can influence men’s visual attention to sexual stimuli; specifically, AD can attenuate the time spent fixated on sexualized targets.Palmer-Hague JL, Tsang V, Skead C, et al.
