What role does AllergieCheck | IgE-Antikörper Test play in fertility?

The AllergieCheck (IgE antibody test) measures specific IgE against foods or inhalants. There is no strong scientific evidence directly linking IgE-mediated allergies to fertility outcomes. Allergic inflammation and histamine release could theoretically affect implantation or sperm function, but human studies are limited and often confounded. For couples with infertility, established diagnostic steps (hormones, tubal patency, semen analysis, lifestyle) are far more relevant. An IgE test may be useful if there are clear allergic symptoms, but it is not recommended as a routine fertility test. Be cautious of marketing claims that overstate its role.
