Can IgG Unverträglichkeitstest help with Fruchtbarkeit?

Can an IgG intolerance test help with fertility? The scientific answer is no. IgG food sensitivity tests are widely marketed but lack validation. They measure IgG antibodies to foods, which are a normal immune response to food proteins and do not indicate intolerance or allergy. Major medical organizations (e.g., EAACI, AAAAI) advise against their use for diagnosing food-related issues. There is no credible evidence linking IgG test results to improved fertility. While diet quality can influence fertility (e.g., Mediterranean diet, adequate micronutrients), IgG-based elimination diets are not supported by data and may even cause harm by leading to unnecessary restrictions and nutrient deficiencies. For fertility concerns, evidence-based approaches include assessing hormonal balance, ovulation, sperm quality, and lifestyle factors (weight, stress, smoking). A registered dietitian or reproductive specialist can provide personalized guidance. In summary, IgG intolerance tests are not a useful tool for fertility and should be avoided.
