Higher testosterone levels are associated with unfaithful behavior in men


Klimas, C; Ehlert, Ulrike; Lacker, T J; Waldvogel, Patricia; Walther, Andreas (2019). Higher testosterone levels are associated with unfaithful behavior in men. Biological Psychology, 146:107730.

Abstract

BACKGROUND
Infidelity in romantic relationships is a common, but severe issue often causing breakup and severe psychological impairment. Higher levels of testosterone are related to mating-behavior, sexual desire, and infidelity in men with sexual dysfunctions. Previous studies, have insufficiently addressed the potential role of testosterone in infidelity in healthy men.
METHODS
A sample of 224 middle-aged self-reporting healthy men being currently in a relationship completed questionnaires on relationship characteristics, infidelity, and provided overnight-fasting saliva samples for testosterone quantification.
RESULTS
In the sample, 37.5% men answered having been unfaithful in the current relationship, while 29% were identified as fulfilling criteria for a sexual dysfunction. Adjusting for covariates, a significant positive association for the frequency of unfaithful behavior and testosterone levels emerged. Subsample analysis indicates a positive association between testosterone and infidelity only to be present in men without sexual dysfunction.
CONCLUSION
Unfaithful behavior in males is associated with higher testosterone levels.
