Dr. Benjamin Campbell, an associate professor at the University of Wisconsin, received his PhD in biological anthropology from Harvard. He is generally interested in the evolutionary study of the human life course, hormones as modulators of human biology and behavior, and neuroanthropology.
Campbell applies these interests in the embodiment of masculinity among Ariaal men, pastoral nomads of the Marsabit District in Kenya. Embodiment, to Campbell, refers to the experiences of the body that provide context for cognition, including things like muscle tone, heart rate, and endocrine release. In this way, testosterone can be thought of as something that is “embodied” in the experiences of Ariaal men. Campbell hypothesizes that since testosterone is embodied, varying levels of testosterone can then affect the well-being (specifically the energy levels, libido, and enjoyment of life) of Ariaal men in a measurable and meaningful way.
In order to test this hypothesis, Campbell used the World Health Organization (WHO) quality of life questionnaire (WHOQOL) with 205 men in two different settlements, one nomadic and one close to a town, and collected saliva samples to test testosterone levels. Once he controlled for dopaminergic sensitivity (based on the Taq1 A1+ genotype, received from hair samples), residence (nomadic encampment or town settlement), and age group he ran a regression analysis to model the relationship of testosterone levels to the outcomes of satisfaction with energy, positive emotions, and satisfaction with sex which form his well-being outcomes. Of these, testosterone is linked with an increase in satisfaction with energy and positive emotions, though residence remains a stronger and larger predictor of the outcomes. In this way, embodying masculinity, in the form of increased testosterone levels, is associated with well-being.
From this conclusion, Campbell claims a “nearly” universal relationship between testosterone and well-being in men. However, the only other studies he cites to make this claim were done in Germany, the U.S.A., and Finland. It seems that more research would need to be done in countries in various geographic regions in order to be able to make any claims of a larger pattern of testosterone levels relating to well-being. Further, the exact pathways by which it does so would need to be explored in more detail. Of the variables used in this study, the one with the largest effect size and significance related to well-being had to do with living in the nomadic encampment, which Campbell suggests could be due to the men living closer to their cultural roots. If we are conceding that living in line with valued cultural roots contributes importantly to well-being, then we would need to somehow control for the possibility that it is living up to the cultural “model” of manliness, which testosterone might contribute to, rather than the testosterone itself, that is contributing to well-being. Along these lines, the socioculturally constructed nature of the gender role of “masculinity” would need to be further explored within each of the different contexts in which testosterone is being tested for its contributions to well-being.
For further consideration:
- What, according to Campbell, is the relationship between embodiment and emotion?
- What are some of the benefits of looking at the relationship between a hormone and well-being? What are some of the drawbacks?
- What methodological changes could be made to address some of the further research questions either brought up here or in Campbell’s chapter itself?
