What to watch with AMH and menopause?

AMH (Anti-Müllerian Hormone) is a key biomarker for ovarian reserve—the number of remaining eggs. Low AMH indicates declining fertility and can roughly estimate menopause onset (typically ~5 years after AMH drops below 0.1 ng/ml). However, AMH is not a precise predictor: individual variation is high, assays differ, and the level says nothing about overall health or age-related disease risk. AMH naturally declines with age—a low value in a 45-year-old is expected, not alarming. Important: AMH tests are useful for fertility assessment but not for pinpointing exact menopause age. Misinterpretation can cause unnecessary anxiety. Evidence: human-moderate (strong association with ovarian reserve, but limited for precise menopause timing).
