However, most HLA-DQ2 carriers never develop celiac disease; penetrance is low. Direct evidence linking HLA-DQ2 alone to fertility outcomes in the absence of celiac disease is lacking. Studies indicate that unexplained infertility and recurrent miscarriage are more common in women with active celiac disease, but the genotype alone has no predictive value for fertility. Genetic testing cannot replace clinical evaluation. If celiac disease is suspected, serology (tTG-IgA) and duodenal biopsy are required. The evidence for an HLA-DQ2–fertility link is moderate, based on association studies rather than causal genetics. MyBody-X tests do not provide clinically validated fertility predictions. Caution: a positive result does not indicate current or future fertility problems.","area":"gesundheit","canonical_id":"gesundheit:canonical-365ab103df82946e582b379c","id":"public-bcd746b484bf3f74780e2aa2","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: HLA-DQ2 in the context of Fruchtbarkeit","score":22.56397528,"snippet":"HLA-DQ2 is a genetic risk factor for celiac disease, an autoimmune condition that, if untreated, can impair fertility through malabsorption, inflammation, or hormonal imbalances.

Untreated celiac disease is associated with fertility issues due to chronic inflammation and nutrient malabsorption (iron, folate, vitamin D). However, the genetic test alone does not confirm active disease; serology (tTG-IgA) and duodenal biopsy are required. Many individuals with risk genotypes never develop celiac. In the fertility context, the test is only a preliminary clue, not a basis for clinical decisions. The evidence for direct benefit of genetic testing in unexplained infertility is mixed. Recommendation: If celiac is suspected (e.g., gastrointestinal symptoms, unexplained iron deficiency), pursue standard diagnostic workup. A DNA test alone is insufficient. Safety note: Do not start a gluten-free diet without confirmed diagnosis, as it can mask symptoms and delay proper testing.","area":"gesundheit","canonical_id":"gesundheit:canonical-cda7a34df1784631cdb265f1","id":"public-cf6d922b40de0502a28f25fa","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: Zöliakie Test in the context of Fruchtbarkeit","score":20.79557575,"snippet":"A celiac genetic test (HLA-DQ2/DQ8) can indicate an increased risk for celiac disease, but it is not a standalone diagnostic test.
