Fertility Check | Fruchtbarkeits-Test: which blood markers matter?

The provided context does not contain specific information about blood markers for a fertility check. The texts focus on DNA tests for skin aging, caffeine metabolism, and nutrition, not on fertility parameters. Therefore, the evidence for this question is unclear based on the given material. In clinical practice, key fertility blood markers include anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, TSH, prolactin, and vitamin D. These markers help assess ovarian reserve, hormonal balance, and potential cycle disorders. However, this information comes from general medical knowledge, not from the sources provided. A DNA test alone cannot replace these blood measurements, as it does not reflect current hormone levels. For a meaningful fertility assessment, a blood test performed by a doctor or through a certified laboratory is necessary. The evidence for these markers is well-established in medicine, but it is not supported by the context given. Therefore, I recommend relying on proven clinical parameters and being aware of the limitations of genetic tests.
