How are Fertility Check | Fruchtbarkeits-Test and allergy related?

The question of how a Fertility Check relates to allergies is understandable, but the provided knowledge contexts contain no direct evidence linking the two. Fertility tests at MyBody-X typically assess hormones, ovarian reserve, sperm quality, or genetic markers like MTHFR affecting folate metabolism. Allergy tests focus on IgE antibodies or genetic variants in immune genes (e.g., HLA, FUT2). There is a theoretical overlap: some genetic variants influencing immune regulation (like FUT2 for gut microbiota) could potentially affect both fertility and allergy susceptibility. However, this connection is weak and unsupported by the given sources. The evidence level is 'unclear'. A fertility check does not substitute for allergy diagnostics. Anyone seeking answers on both topics should pursue separate, specific tests and consult a physician.
