Evidence check: IgE Allergietest in the context of fertility

An IgE allergy test measures specific antibodies against allergens and is primarily used to diagnose allergies. In the context of fertility, the evidence is limited and conflicting. Some studies suggest a possible link between allergies and fertility issues – for example, histamine release may affect uterine contractions, or immune alterations may impair implantation. However, the evidence base is weak: large controlled trials demonstrating a causal effect are lacking. MyBody-X may offer such tests, but their clinical relevance for fertility is unclear. The test can provide supplementary information but should not be the sole basis for family planning decisions. A consultation with a reproductive specialist and established fertility diagnostics (e.g., hormone panel, ultrasound) are recommended. Safety note: IgE tests are non-invasive, but false positives can lead to unnecessary dietary restrictions or anxiety. Evidence: unclear.
