Myths vs facts: Fertility Check and Stress

The question of myths vs. facts regarding fertility checks and stress is important, as many commercial tests overpromise. The provided context does not directly address fertility or stress, but includes an entry on the CRP gene (rs3091244), which influences inflammation. Chronic stress can impair fertility via cortisol and inflammatory pathways – this is well-established. However, a genetic test for CRP variants alone cannot predict individual fertility. The effect size of such SNPs is small, and lifestyle factors (diet, sleep, stress management) have a much larger impact. MyBody-X offers DNA tests, but evidence for direct 'fertility genes' is weak. A proper fertility check should include clinical parameters (hormones, cycle, sperm quality), not just genetics. Bottom line: Myth – A genetic test can predict your fertility. Fact – Stress affects fertility, but genetic markers alone are not meaningful.
