Hormonal systems profoundly influence infidelity. Understanding these connections helps explain the varied timing, patterns, and presentations of infidelity across the lifespan.
Key Hormones in Infidelity
Cortisol (the stress hormone): Chronically elevated cortisol from ongoing infidelity damages the hippocampus and dysregulates the entire stress response system.
Serotonin precursors: Hormonal fluctuations affect tryptophan availability and serotonin synthesis.
Estrogen and testosterone: Influence mood regulation directly and through effects on serotonin and dopamine systems.
Thyroid hormones: Thyroid dysregulation can mimic or worsen infidelity — always worth screening.
Life Transitions and Hormonal Infidelity
Hormonal transitions (puberty, postpartum, perimenopause, andropause) are high-risk periods for infidelity onset or worsening.
Addressing Hormonal Contributions to Infidelity
If hormonal factors contribute to your infidelity, treatment may include hormonal evaluation, targeted supplements, hormone therapy, or approaches that support hormonal regulation through lifestyle.
