Can Zöliakie Test help with fertility?

A celiac test can be helpful for unexplained infertility if undiagnosed celiac disease is present. Untreated celiac disease is linked to fertility issues in both women (menstrual irregularities, miscarriages) and men (reduced sperm quality). The test typically measures antibodies (tTG-IgA) or genetic risk markers (HLA-DQ2/DQ8). However, a positive genetic test alone indicates only predisposition, not active disease – serology is the clinical gold standard. Without a gluten-free diet, fertility rarely improves. The evidence for the celiac–fertility link is human-moderate, but not all consumer tests provide clinically actionable results. MyBody-X and similar tests often offer only genetic risk screening, not a diagnosis. For couples struggling with infertility, a physician should guide celiac workup. Caveat: infertility is multifactorial; celiac is just one possible contributor.
