Evidence check: Fertility Check | Fruchtbarkeits-Test in the context of Sport

The combination of a fertility test and sport is not directly supported by the provided context. The Hormon VitalCheck for men (MyBody-X) is a direct-to-consumer test without publicly available clinical validation. Exercise can influence hormone levels (e.g., testosterone, cortisol), but a single test does not provide reliable fertility assessment. Evidence for such tests is weak (marketing/unclear). For fertility concerns, consult a reproductive specialist, especially for athletes with cycle irregularities or performance issues. No validated SNP or biomarker panels for sport-fertility are present in the sources. Safety note: self-interpretation may lead to incorrect decisions.
