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

Fertility Check tests, such as hormone panels or genetic screenings, are primarily designed for reproductive health assessment. In the context of sport, there is no validated direct application. While some parameters like testosterone, estrogen, or AMH may indirectly relate to athletic performance – e.g., through muscle mass, recovery, or bone density – these links are complex and not sufficient to guide training or nutrition decisions. Genetic variants associated with fertility (e.g., FSHR polymorphisms) typically have small effect sizes on performance. The evidence level is best described as 'mechanistic' to 'unclear'. Marketing claims suggesting a direct benefit for athletes should be viewed critically. A fertility test does not replace performance diagnostics and should not be used to enhance athletic output.
