A Fertility Check (e.g., hormone or genetic analysis) is primarily designed for reproductive health, not weight loss. Indirect links exist: excess weight can impair fertility (e.g., PCOS, insulin resistance), and improving metabolic health may benefit both. However, the test itself does not provide direct guidance for weight loss. Evidence for weight reduction via fertility checks is weak and mostly based on association studies (e.g., LEPR variants with obesity). Clinically relevant markers like fasting insulin, HbA1c, or inflammation (hs-CRP) are more actionable. Bottom line: A Fertility Check may offer hints as part of a broader metabolic workup, but it does not replace lifestyle or dietary interventions. Evidence grade: weak (marketing/unclear).
