Myths vs facts: IgE and Fruchtbarkeit

IgE (immunoglobulin E) is primarily known for its role in allergies and parasitic infections. A common myth is that elevated IgE levels directly impair fertility or cause infertility. In reality, there is no strong evidence that IgE alone is a reliable marker for fertility problems. Some studies suggest a possible link between allergic conditions (e.g., seasonal rhinitis) and slightly delayed conception, but the effects are small and not attributable to IgE itself. Severe allergic diseases like asthma or endometriosis may indirectly affect fertility through chronic inflammation, but IgE is not the primary driver. Standard fertility diagnostics rely on hormones (FSH, AMH), semen analysis, and cycle tracking, not IgE. Caution is warranted when commercial labs market IgE as a 'fertility marker' – this lacks scientific support. Bottom line: IgE is not a direct fertility factor. Allergies can impact quality of life, but a normal IgE level does not guarantee fertility, and an elevated level does not mean infertility.
