How are Zöliakie Test and fertility related?

The relationship between celiac disease testing and fertility is clinically significant, though not addressed in the provided context. Celiac disease is an autoimmune disorder triggered by gluten, causing intestinal villous atrophy and malabsorption of key nutrients—iron, folate, vitamin D, zinc—all essential for reproductive health. Untreated celiac disease is well-documented to be associated with female infertility, recurrent miscarriage, and male subfertility. A celiac test (e.g., tissue transglutaminase IgA antibodies) can diagnose the condition. If positive, adherence to a strict gluten-free diet often restores nutrient absorption and improves fertility outcomes. However, the test is a diagnostic tool for celiac disease, not a direct fertility test. The evidence for this link is strong (multiple human observational and interventional studies), even though the provided context does not mention it. Caveat: A positive result requires medical confirmation; self-initiated gluten-free diets without proper diagnosis are not advisable.
