Evidence check: Fertility Check | Fruchtbarkeits-Test in the context of fertility

The Fertility Check / Fruchtbarkeits-Test is marketed as a comprehensive analysis for reproductive health. Typical components include hormone measurements (FSH, LH, AMH, progesterone, testosterone) and genetic markers (e.g., MTHFR, Factor V Leiden, IL-6). The evidence for the clinical utility of such genetic tests in fertility is weak to moderate. Hormonal single factors like AMH or FSH have established value for assessing ovarian reserve, but the added genetic information usually has small effect sizes and does not provide a diagnosis. The results should be seen as a screening tool, not a substitute for a full medical fertility workup. Lifestyle, age, cycle phase, and comorbidities strongly influence values. Without medical interpretation, the test may lead to false conclusions or unnecessary anxiety. The provided context contains no direct studies or PMIDs for this specific test, so the evidence rating is 'marketing' or 'unclear'. Consumers should critically evaluate whether the offered markers are scientifically supported and whether professional medical follow-up is included.
