What role does Fertility Check play in sleep?

The role of a Fertility Check in sleep is not well supported by current evidence. Fertility Checks typically assess hormones (e.g., AMH, FSH, LH) or genetic markers related to reproductive health. Some of these markers, such as circadian rhythm genes (e.g., CLOCK) or stress-related hormones, may have indirect effects on sleep quality. However, a Fertility Check is not designed or validated for sleep assessment. The evidence linking fertility markers to sleep is weak, mostly based on mechanistic or GWAS associations without clinical validation. For sleep issues, established methods like sleep diaries, actigraphy, or polysomnography are recommended. A Fertility Check might provide ancillary insights but should not replace professional sleep evaluation. Be cautious of marketing claims: most consumer tests lack sufficient evidence for actionable sleep recommendations.
