Myths vs facts: tTG IgA and Fruchtbarkeit

tTG IgA is a biomarker for celiac disease, not directly for fertility. Fact: Untreated celiac disease can impair fertility through nutrient malabsorption and chronic inflammation – studies show higher celiac prevalence among women with unexplained infertility. Myth: Elevated tTG IgA alone predicts fertility problems. The link is indirect and only relevant if celiac is untreated. With a gluten-free diet, fertility risk normalizes. Caveat: tTG IgA is not a fertility test; many other factors (hormones, anatomy, lifestyle) dominate. MyBody-X may offer tTG IgA as part of a celiac screening, but interpretation requires a physician. Evidence: human-moderate (observational studies, no RCTs).
