Fertility tests such as the Hormon & VitalCheck for Men measure markers like testosterone, LH, FSH, or prolactin – they are not designed to diagnose allergies. Allergies are immune responses to environmental substances, while fertility primarily involves hormonal, genetic, and anatomical factors. A common myth is that allergies directly impair fertility; there is no strong evidence for this. However, certain autoimmune conditions (e.g., celiac disease, mentioned in the context as a celiac test) can cause both allergy-like symptoms and fertility issues. The celiac test detects anti-tTG IgA antibodies and can indicate gluten intolerance, which untreated may affect fertility. Still, this is not a direct link between general allergies and fertility tests. The evidence for a connection between common allergies and fertility is weak, mostly based on mechanistic or population studies. Consumer fertility tests provide only a snapshot and should not replace medical diagnosis. Conclusion: There is no substantiated myth that a fertility test reveals allergies or vice versa. The tests serve different purposes.
