How are Fitness | LifestyleCheck and Fruchtbarkeit related?

The MyBody-X 'Fitness | LifestyleCheck' and 'Fertility' tests overlap in several biomarkers that influence both domains. The LifestyleCheck measures typical fitness and metabolic markers (e.g., blood lipids, inflammation markers, antioxidant status), while the fertility test additionally captures sex-specific hormones (estradiol, progesterone, testosterone, AMH) and thyroid values. A direct link exists via oxidative stress, inflammation, and hormonal balance: poor lifestyle (unhealthy diet, lack of exercise, chronic stress) can impair fertility by affecting egg quality or sperm parameters. The tests provide indications but not a diagnosis. Evidence for the predictive power of such consumer tests on fertility is weak to moderate; many associations stem from observational studies. A doctor's visit and possibly extended hormone diagnostics are essential when trying to conceive. Test results should serve as orientation, not as a sole basis for decisions.
