Work out menopause age estimate instantly with clear inputs, formula shown and shareable results.
Anchors an estimate on the mother's age at menopause, the strongest single predictor, and applies the reported one to two year advance seen in smokers.
Heritability-anchored estimate
Estimated age = mother's age at menopause - 1.5 years if a current smoker; the average natural menopause age is about 51
Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
Heritability of menopause age is estimated at roughly 50%, so it shifts the estimate without fixing it.
Menopause before 45 is early and before 40 is classified as premature ovarian insufficiency.
