Myths vs facts: Fertility Check | Fruchtbarkeits-Test and sleep

The relationship between fertility tests and sleep is often misunderstood. A fertility check (e.g., AMH, FSH, LH) does not measure sleep, but poor sleep can alter cortisol and melatonin, potentially disrupting ovulation and sperm quality. Myths: 'A test tells you everything about your fertility' – false; it's a snapshot, not a diagnosis. 'Sleep alone causes infertility' – overstated; chronic sleep deprivation may modestly affect cycles. Facts: Adequate sleep (7–9 h) supports hormonal balance. Evidence is mostly observational, not causal. Consumer tests lack clinical validation for sleep-fertility links. Consult a doctor for comprehensive assessment.
