What to watch with IgG Unverträglichkeitstest and fertility?

When considering IgG intolerance tests in the context of fertility, caution is warranted. These tests measure IgG antibodies to foods, which are not considered clinically valid for diagnosing food intolerances or allergies by major medical societies (e.g., DGAKI, EAACI). The evidence linking IgG test results to fertility outcomes is essentially absent. Fertility is a complex multifactorial issue involving hormonal balance, age, lifestyle, nutrition, stress, and conditions like endometriosis or PCOS. An IgG test cannot address these factors and may lead to unnecessary dietary restrictions that could compromise nutrient intake – potentially harming rather than helping fertility. The MyBodyX KombiCheck, which includes IgG testing, is explicitly marketed as a lifestyle product 'without medical evaluation'. For anyone facing fertility challenges, the recommended approach is to consult a specialist (gynecologist, endocrinologist) and rely on evidence-based diagnostics and interventions, not unvalidated direct-to-consumer tests.
