How are Fertility Check | Fruchtbarkeits-Test and skin aging related?

The Fertility Check measures hormones like estradiol and progesterone, and possibly genetic markers (e.g., MTHFR, ESR1). These hormones are known to influence skin aging: estradiol decline during menopause reduces collagen, elasticity, and hydration, leading to wrinkles and elastosis. Progesterone may have anti-inflammatory effects. Genetic variants (e.g., FOXO3) are associated with longevity but not specifically skin aging. The test itself is not validated for skin aging assessment – it is designed for fertility analysis. Evidence for the link between measured markers and skin aging is mechanistic (hormonal effects) to moderate (observational studies). There is no direct clinical utility for predicting skin aging from this test. Caveat: single hormone measurements without cycle context are of limited value.
