Is AllergieCheck | IgE-Antikörper Test useful for Fruchtbarkeit?

The AllergieCheck (IgE antibody test) is designed for allergy diagnosis, not fertility assessment. There is no robust scientific evidence linking IgE levels directly to fertility. Fertility depends on a complex interplay of hormones, egg and sperm quality, age, lifestyle, and genetics. An IgE test might be indirectly relevant if untreated allergies cause chronic inflammation or medication use that could affect fertility, but this is speculative and not supported by studies. Marketing such tests as a 'fertility check' is misleading. Consumers should rely on validated methods like hormone panels (FSH, AMH, progesterone) and clinical fertility evaluations. This test provides no actionable information for family planning. Evidence grade: marketing/unclear. Safety note: Do not make medical decisions based on this test.
