What to watch with IgG and fertility?

IgG antibody tests are often marketed as food sensitivity tests and linked to fertility issues, but the scientific evidence is weak. Elevated IgG levels typically reflect normal immune exposure, not true intolerance or inflammation that impairs fertility. Some studies suggest a possible role of chronic low-grade inflammation in infertility, but IgG testing is not a validated diagnostic tool. MyBody-X does not offer such tests. Instead, prioritize established fertility markers like AMH, TSH, prolactin, vitamin D, and iron status. Be cautious of expensive elimination diets based on IgG results; they may lead to nutrient deficiencies. Always consult a reproductive specialist for evidence-based fertility assessment.
