Can tTG IgA help with Fruchtbarkeit?

The tTG IgA test (tissue transglutaminase IgA) is a well-established serological marker for celiac disease. A positive result indicates untreated celiac disease, which is associated with fertility issues in both women (prolonged time to pregnancy, recurrent miscarriage) and men (reduced sperm quality). The evidence for this link is human-strong: numerous studies demonstrate that a gluten-free diet in celiac patients can improve fertility outcomes. However, the tTG IgA test does not directly help with fertility; it serves to diagnose a potential underlying cause. In cases of unexplained infertility, celiac screening may be considered, especially if accompanied by symptoms like unexplained gastrointestinal issues or iron deficiency. Important: a positive test should be confirmed by duodenal biopsy before starting a gluten-free diet. The test alone does not replace a full fertility workup. The provided contexts contain no direct information on tTG IgA or fertility; this answer is based on generally accepted medical knowledge.
