How are Fertility Check and Fruchtbarkeit related?

The terms 'Fertility Check' and 'Fruchtbarkeit' in the MyBody-X context refer to tests that analyze genetic and/or microbiome markers for fertility. However, the provided knowledge context contains no specific information about these tests. There are no validated, evidence-based links between the mentioned markers (e.g., ACTN3, LEPR, MTHFR, FADS2) and fertility. These tests are therefore informational only and not diagnostic. A Fertility Check may offer general hints but cannot replace clinical fertility evaluation. The evidence level is 'marketing' or 'unclear'.
