How are IgG Unverträglichkeitstest and fertility related?

The relationship between IgG food intolerance tests and fertility is not scientifically established. IgG tests measure delayed immune responses to foods, but their clinical utility is controversial. Most gastroenterology and allergy societies do not recommend IgG testing for diagnosing food intolerances. While some practitioners claim that eliminating foods identified by IgG tests can reduce inflammation and improve fertility, there is no robust evidence from randomized controlled trials to support this. Fertility is influenced by many factors including hormonal balance, age, genetics, and lifestyle. Chronic inflammation may play a role in some fertility issues, but IgG tests are not a validated tool to assess or treat such inflammation. The gold standard for identifying food sensitivities remains a supervised elimination diet. Therefore, relying on IgG tests for fertility concerns is not evidence-based and may lead to unnecessary dietary restrictions. Consumers should consult a reproductive specialist or registered dietitian for personalized advice.
