Can HLA-DQ2 help with Fruchtbarkeit?

Based on the provided context, there is no direct evidence that HLA-DQ2 can help with fertility. HLA-DQ2 is a genetic variant strongly linked to celiac disease. Some studies suggest that untreated celiac disease may contribute to fertility issues due to malabsorption or systemic inflammation. However, HLA-DQ2 is only a risk factor; most carriers never develop celiac disease. There is no scientific support for a beneficial role of HLA-DQ2 in fertility. The evidence grade is 'unclear' because the context lacks relevant data. Individuals with known HLA-DQ2 status and fertility concerns should consult a healthcare provider for a comprehensive evaluation, including celiac serology and dietary assessment. Genetic testing alone is not a diagnostic or therapeutic tool for fertility.
