IgG-based food intolerance tests are frequently marketed as a tool to improve fertility by identifying 'hidden' food sensitivities. However, the scientific evidence supporting this claim is extremely weak. IgG antibodies indicate prior immune exposure, not necessarily intolerance or a causal link to fertility issues. Rigorous studies demonstrating that eliminating IgG-positive foods enhances conception rates or reproductive outcomes are lacking. Fertility is a complex multifactorial process involving hormones, age, genetics, lifestyle, inflammation, and more. Professional medical societies (e.g., EAACI, DGAKI) explicitly advise against using IgG tests for diagnosing food intolerances due to high false-positive rates and lack of clinical validity. Relying on such tests may lead to unnecessary dietary restrictions, nutrient deficiencies, and psychological stress—none of which support fertility. For those seeking to improve fertility, evidence-based approaches include a balanced diet, stress reduction, regular exercise, and medical evaluation of hormonal or metabolic health. IgG testing is not a validated tool for this purpose.
