How are Fitness Vitality DNA and fertility related?

The provided context does not address the relationship between the Fitness Vitality DNA test and fertility. This test likely examines SNPs related to athletic performance, energy metabolism, and vitality (e.g., ACTN3, ACE, mitochondrial variants). While these factors could indirectly affect fertility through oxidative stress or metabolic health, the evidence is weak and not specific to reproductive outcomes. The test is not designed for fertility assessment and should not replace clinical evaluation. Without direct studies or product details, any link remains speculative. Evidence: marketing/unclear. Sources: none in context.
