How are Testosteron and allergy related?

The relationship between testosterone and allergies is not well-established scientifically. Mechanistic studies suggest testosterone may modulate immune responses, potentially suppressing TH2-driven allergic inflammation. Some observational data show sex differences in allergy prevalence, with males often having lower rates, but confounding factors (e.g., lifestyle, hormone fluctuations, comorbidities) limit causal interpretation. No robust clinical trials or validated biomarkers exist to link testosterone levels directly to allergy risk or severity. Consumer tests (e.g., MyBody-X) claiming to assess this connection lack published evidence and are not recommended by allergy guidelines. Evidence grade: unclear/mechanistic. Caveat: Hormonal changes (puberty, pregnancy, androgen therapy) may influence allergic symptoms, but individual predictions are not reliable. For allergy diagnosis, standard IgE-based testing remains the gold standard.
