What role does Cortisol senken play in fertility?

The role of lowering cortisol in fertility is not well established by high-quality evidence. Cortisol, a key stress hormone, can disrupt reproductive hormones when chronically elevated – observational studies link high stress to menstrual irregularities and lower sperm quality. However, no large RCTs have proven that actively reducing cortisol (via supplements, diet, or lifestyle) directly improves fertility outcomes. Many confounders exist. Consumer tests claiming to identify a 'cortisol type' lack clinical validation. Evidence-based stress management (mindfulness, exercise, sleep) may support overall health and indirectly benefit fertility, but should not replace medical evaluation. The evidence is best described as mechanistic or unclear, not strong.
