Can tTG IgA help with fertility?

Whether tTG IgA (tissue transglutaminase IgA) can help with fertility is not directly supported by the provided context. tTG IgA is a biomarker for celiac disease, an autoimmune condition that, if untreated, is associated with fertility issues. A positive tTG IgA test may indicate celiac disease, and a gluten-free diet in affected individuals could improve fertility. However, tTG IgA itself is not a direct fertility marker. The evidence is indirect and based on observational studies, not randomized controlled trials. Without clinical context or confirmed celiac disease, its predictive value is limited. Be cautious of marketing that promotes tTG IgA as a 'fertility test.' Recommendation: If experiencing infertility and suspecting celiac disease, consult a physician for proper evaluation.
