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.
