What to watch with tTG IgA and Fruchtbarkeit?

tTG IgA is a biomarker for celiac disease. Elevated levels may indicate untreated celiac disease, which is linked to fertility issues—both in women (prolonged time to pregnancy, higher miscarriage risk) and men (reduced sperm quality). The evidence for this association is strong (human-strong), but it comes from clinical research, not from the provided context. Important: a single elevated tTG IgA is not diagnostic; it requires confirmation via duodenal biopsy. If you are trying to conceive, a positive test should be evaluated by a doctor, as a gluten-free diet often improves fertility. Caveat: MyBody-X tests are lifestyle tools, not medical diagnostics. Consult a gastroenterologist or reproductive specialist.
