Evidence check: Cortisol senken in the context of Fruchtbarkeit

The evidence linking cortisol reduction to improved fertility is not yet conclusive. Cortisol, the primary stress hormone, can disrupt the hypothalamic-pituitary-gonadal axis when chronically elevated, potentially impairing ovulation and sperm quality. Observational studies report associations between high perceived stress, elevated cortisol, and reduced fertility. However, randomized controlled trials demonstrating a causal effect of lowering cortisol (e.g., via stress management, sleep optimization, or supplements like ashwagandha) on pregnancy rates are lacking. Direct-to-consumer cortisol tests (saliva, hair) exist but have unclear clinical validity for fertility optimization. MyBody-X does not currently offer a specific cortisol test; the evidence base is best described as 'mixed' or 'mechanistic'. Medical evaluation remains essential for fertility concerns.
