Myths vs facts: IgE Allergietest and Fruchtbarkeit

There is no robust scientific evidence that an IgE allergy test can directly predict or improve fertility. IgE tests are primarily designed to diagnose type I allergies (e.g., pollen, foods). Some studies suggest a link between chronic allergies and low-grade inflammation that could theoretically affect fertility – for example, through increased mast cell activity in the endometrium. However, the evidence is weak and mostly based on animal models or small observational studies. Most commercial IgE tests are not validated for fertility assessment. Individuals with fertility concerns should consult reproductive medicine specialists rather than making dietary or lifestyle changes based on an IgE test. Conclusion: It is a myth that an IgE test clarifies fertility. The evidence is insufficient.
