However, the scientific evidence is weak: effect sizes of individual SNPs are small, and most studies fail to show clinically relevant predictions for testosterone levels or muscle gain. Moreover, testosterone is heavily influenced by lifestyle, diet, sleep, stress, and inflammation—factors not captured by DTC tests. A further risk is misinterpretation: a 'risk allele' may cause unnecessary anxiety or lead to uncritical supplementation, which in men can cause side effects like acne, sleep apnea, or increased cardiovascular risk. In women, testosterone supplementation can cause virilization. No medical society recommends routine genetic testing for testosterone. The evidence is mostly marketing-driven or based on small, unreplicated association studies. Bottom line: such tests provide no actionable information and should not guide supplementation or training decisions. A physician-supervised blood test (free and total testosterone, SHBG) is far more informative.","area":"gesundheit","canonical_id":"gesundheit:canonical-0353f716fd728ae6fdf31f6c","id":"public-f2402186028db87b599ab915","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Risks and limits of Testosteron Genetik","score":31.8024692,"snippet":"Genetic testing for testosterone-related genes (e.g., AR, SRD5A2, CYP19A1) is often marketed by direct-to-consumer companies as a way to optimize personal testosterone levels or training response.
