Can Testosteron help with allergy?

Whether testosterone can help with allergies is not clearly supported by evidence. Testosterone has immunomodulatory effects – it can suppress Th2 immune responses (dominant in allergies) and reduce IgE production. Some observational studies suggest that men with higher testosterone levels have lower rates of hay fever or asthma. However, the effect is modest and insufficient for therapeutic recommendations. Testosterone therapy for allergies is not approved and carries risks (e.g., cardiovascular effects, hormonal imbalances). Moreover, allergies are influenced by many factors including genetics, environment, and microbiome. The provided context does not contain specific studies on testosterone and allergies. Therefore, the evidence remains mechanistic and mixed. Treating allergies with testosterone is currently not indicated.
