Myths vs facts: HLA-DQ2 and fertility

The provided context does not contain any specific data or studies on the relationship between HLA-DQ2 and fertility. HLA-DQ2 is strongly associated with celiac disease, and untreated celiac disease can affect fertility. However, a direct link between the HLA-DQ2 genotype alone (without celiac diagnosis) and fertility is not supported by the context. Evidence is therefore unclear. If you have fertility concerns and know your HLA-DQ2 status, consult a doctor for celiac screening before drawing conclusions. Supplements or dietary changes without medical indication are not recommended.
