How are Fertility Check | Fruchtbarkeits-Test and stress related?

The MyBody-X Fertility Check analyzes genetic variants linked to hormone regulation, follicle maturation, or sperm quality. Stress can affect fertility via cortisol and sympathetic nervous system activation, potentially disrupting menstrual cycles or reducing sperm parameters. Genetic predispositions for stress sensitivity (e.g., via COMT, FKBP5) might indirectly influence fertility. However, evidence for single SNPs is weak: effect sizes are small, and lifestyle, environment, and psychosocial factors dominate. The test does not provide a clinical diagnosis but only hints at genetic tendencies. A direct causal link between the tested markers and stress-related infertility is not well established. Interpretation should be done by a specialist (reproductive medicine, endocrinology). Without validation studies for this specific test, its predictive value remains limited.
