What role does Fertility Check | Fruchtbarkeits-Test play in weight loss?

The provided context does not contain any information about the Fertility Check (Fruchtbarkeits-Test) and its role in weight loss. While fertility tests may assess hormones like AMH, FSH, or genetic variants related to reproductive health, there is no evidence in the given material linking them directly to weight management. Weight loss can improve fertility in some cases (e.g., PCOS), but the test itself does not cause or guide weight loss. The evidence grade is 'unclear' or 'marketing' based on the lack of context. Consumers should not rely on such tests for weight loss without medical supervision.
