New research suggests that men with higher levels of testosterone tend to devote more energy to keeping their romantic partners faithful and in a relationship with them.
The study, published in the journal Physiology & Behavior, examined what is known as mate retention behavior.
“By contrast, very little research has examined whether testosterone relates to other forms of mating-relevant competition, such as effort aimed at retaining a mating partner.
The researchers collected saliva samples from 108 male undergraduates to measure their testosterone levels and had them complete surveys on mate retention and intrasexual competition.
“Our results suggested that there is a modest relationship between testosterone and mate-retention, but that this relationship is not direct in nature.
“Moreover, this relationship seems to be strongest for cost inflicting, rather than benefit provisioning, acts of mate retention.”.
The study, “Intrasexual competition mediates the relationship between men’s testosterone and mate retention behavior“, was co-authored by Graham Albert, Justin M. Carré, and Triana L. Ortiz. »
