Can DNA Stoffwechseltest help with Fruchtbarkeit?

A DNA metabolism test (e.g., MyBody-X Slim) can provide information on genetic variants in genes like FTO, MC4R, or ADIPOQ that influence energy balance, appetite, and insulin sensitivity. These factors can indirectly affect fertility, as a healthy metabolism and normal body weight are important for reproductive health. However, the evidence is weak: individual gene variants have small effect sizes (e.g., 0.3–0.5 kg/m² per risk allele for FTO), and no randomized controlled trials show that DNA-based dietary advice improves fertility. Fertility is multifactorial – hormones, age, lifestyle, environment, and medical conditions play a much larger role. The test does not replace a medical fertility evaluation. Caution: results may lead to misinterpretation or false hope. My advice: use the test only as inspiration for a healthier lifestyle, not as a basis for family planning decisions.
