Myths vs facts: Fertility Check and Haut

Myths vs. facts: Fertility Check and Skin. Many direct-to-consumer DNA tests claim to reveal genetic risks for fertility or skin aging (e.g., glycation, collagen loss). The evidence is weak: most SNPs have small effect sizes, and lifestyle factors dominate. For fertility, hormone status, cycle tracking, and clinical workup are far more relevant than a DNA test. For skin, UV exposure, diet, and skincare matter more than individual genes. MyBody-X itself disclaims medical use. A combined test (blood markers like HbA1c, CRP, ferritin plus microbiome) may be more useful but does not replace professional advice. Bottom line: DNA tests for fertility and skin are often marketing; facts rely on clinical routines and validated biomarkers.
