How are Fertility Check | Fruchtbarkeits-Test and weight loss related?

The Fertility Check (Fruchtbarkeits-Test) from MyBody-X analyzes genetic markers related to reproductive health, such as hormone regulation, ovarian reserve, or sperm quality. Weight loss is a separate domain, but there is a well-known physiological link: excess body weight (especially visceral fat) can impair fertility through hormonal disruptions (e.g., elevated estrogen, insulin resistance). Conversely, moderate weight loss can improve fertility outcomes, particularly in conditions like PCOS or obesity. The Fertility Check itself does not provide weight loss guidance. Evidence for DNA-based personalized diets for weight loss is weak (see FTO/MC4R variants). Thus, the two tests are complementary but not causally connected. Users should interpret results separately and focus on evidence-based lifestyle measures.
