Can IgG help with Fruchtbarkeit?

Whether IgG antibodies can help with fertility is not scientifically well-established. IgG food sensitivity tests are often marketed for various health issues, but evidence linking them directly to improved fertility is weak. Mechanistic hypotheses suggest that chronic low-grade inflammation from food antigens might impair implantation or sperm quality, but rigorous clinical trials are lacking. The provided context does not include any studies specifically on IgG and fertility—the listed research covers nutrigenetics, antioxidants, and general precision nutrition. Therefore, no evidence-based recommendation can be made. Safety note: IgG-guided elimination diets may lead to unnecessary restrictions and nutrient deficiencies. For fertility concerns, established medical evaluations (hormone panels, semen analysis, cycle tracking) are more appropriate. The evidence level is 'unclear'.
