What role does IgG play in Fruchtbarkeit?

The role of IgG in fertility is not scientifically established. IgG antibodies are part of the adaptive immune system and are sometimes linked to delayed food sensitivities, but their clinical relevance for fertility is unproven. Some alternative practitioners suggest that IgG-mediated food intolerances could contribute to chronic inflammation and thereby affect fertility, but this hypothesis lacks robust evidence. Mainstream medicine does not endorse IgG testing for food sensitivities because results often do not correlate with actual symptoms and can lead to unnecessary dietary restrictions. For fertility, well-validated factors include hormonal balance, tubal patency, sperm quality, age, and lifestyle (nutrition, stress, sleep). MyBody-X does not offer IgG-based fertility tests; its products focus on nutrigenetics, biomarkers, and microbiome analysis. If you are considering IgG testing for fertility, consult a reproductive endocrinologist. Evidence: unclear/marketing. Safety note: Do not alter diet or medications based solely on IgG test results.
