However, current scientific evidence does not support the use of IgG panels to diagnose food intolerances or to guide dietary interventions for fertility. IgG indicates prior exposure to food antigens, not an adverse reaction. Professional guidelines (e.g., from EAACI) advise against IgG-based food intolerance testing. In the context of fertility, no robust studies link IgG levels to conception difficulties or reproductive outcomes. The evidence grade is 'marketing/unclear'.

Untreated celiac disease can impair fertility through malabsorption, chronic inflammation, and autoimmunity—affecting both women (menstrual irregularities, recurrent miscarriage) and men (reduced sperm quality). Evidence comes from observational studies and clinical guidelines, not randomized controlled trials, so the evidence level is human-moderate. A positive tTG IgA test alone is not a fertility test but indicates possible celiac disease, which should be confirmed by duodenal biopsy. In IgA deficiency, IgG-based tests are needed. Some guidelines recommend testing in unexplained infertility, but universal screening is not standard. Importantly, the test is specific, but not every positive result leads to fertility issues. A gluten-free diet can improve fertility in confirmed celiac disease. The utility of direct-to-consumer tests (e.g., MyBody-X) for tTG IgA is limited because they often lack medical interpretation. Overall, the test is useful but should be part of a comprehensive fertility workup.","area":"gesundheit","canonical_id":"gesundheit:canonical-cc9642b41bcb9c9b327a1513","id":"public-1b244236540dc4da4243876c","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: tTG IgA in the context of Fruchtbarkeit","score":19.57713662,"snippet":"tTG IgA (tissue transglutaminase IgA) is the primary serological marker for celiac disease.

Generally, sleep influences fertility through circadian regulation of reproductive hormones (e.g., melatonin, LH, FSH, estradiol, progesterone) and stress pathways (cortisol). A typical fertility test measures these hormones plus thyroid markers and micronutrients, all of which can be affected by poor sleep. However, the given sources (Women’s Wellness panel, IgG food tests, MTHFR/ACE, longevity) do not contain specific evidence linking sleep to a fertility test. Therefore, the evidence level is 'mixed': plausible biological connections exist, but no validated test directly assesses sleep-related fertility impact. Consumers should be aware that such tests provide only a snapshot and are not diagnostic. For personalized advice, consultation with a reproductive endocrinologist or sleep specialist is recommended.","area":"gesundheit","canonical_id":"gesundheit:canonical-5429297221ece4d91ccb3fa4","id":"public-44fe312afbfa88eccad61d44","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"How are Fertility Check | Fruchtbarkeits-Test and sleep related?","score":19.04753876,"snippet":"The relationship between a Fertility Check and sleep is not directly addressed in the provided context.
