Evidence check: IgE in the context of Fruchtbarkeit

The question of IgE in the context of fertility is specific, but the evidence is limited and mixed. IgE antibodies are primarily associated with allergies, and some studies suggest a possible link between allergic conditions and female fertility – for example through immune system alterations or comorbidities like endometriosis. However, the data are not robust enough to recommend IgE as a standalone biomarker for fertility. Elevated IgE can also result from parasites, autoimmune diseases, or smoking. In fertility diagnostics, hormones, AMH, cycle parameters, and semen analysis play a much larger role. An isolated IgE finding without clinical allergy symptoms has little relevance in this context. MyBody-X tests provide no clinical diagnosis, only a hint that should be discussed with a physician. The evidence for a direct causal role of IgE in fertility issues is weak and based mostly on observational studies. Caution against overinterpretation is warranted.
