Evidence check: IgG in the context of Fruchtbarkeit

IgG antibody testing for food sensitivities is often marketed for various health concerns, including fertility. However, current scientific evidence does not support the use of IgG panels to diagnose food intolerances or to guide dietary interventions for fertility. IgG indicates prior exposure to food antigens, not an adverse reaction. Professional guidelines (e.g., from EAACI) advise against IgG-based food intolerance testing. In the context of fertility, no robust studies link IgG levels to conception difficulties or reproductive outcomes. The evidence grade is 'marketing/unclear'. For fertility issues, focus on validated assessments such as hormonal profiling, ovarian reserve, semen analysis, and lifestyle factors. A balanced diet may support fertility, but IgG testing is not a reliable tool.
