How are Cortisol and Fruchtbarkeit related?

Cortisol and fertility are linked via the hypothalamic-pituitary-adrenal (HPA) and hypothalamic-pituitary-gonadal (HPG) axes. Chronically elevated cortisol – often due to prolonged stress – can suppress GnRH, LH, and FSH secretion, leading to menstrual irregularities, anovulation, and reduced conception rates in women. In men, high cortisol inhibits testosterone production and spermatogenesis. Evidence is based on human observational studies and mechanistic animal models; effect sizes are moderate and highly individual. A single cortisol measurement (saliva, blood, or urine) is a snapshot and not diagnostic for fertility issues due to diurnal variation and stress reactivity. Comprehensive fertility assessment requires specific hormone panels (LH, FSH, estradiol, progesterone, testosterone) and clinical evaluation. MyBody-X tests do not provide a complete fertility workup. Individuals suspecting stress-related fertility problems should consult a physician and consider stress management and lifestyle modifications.
