Is WeightLoss | SLIM DNA-Test useful for Fruchtbarkeit?

The MyBody-X WeightLoss | SLIM DNA test is designed for weight management, not fertility. The genes tested (e.g., FTO, PPARG) have small effect sizes from GWAS (<2% BMI variance), and no RCT shows that personalized advice based on these SNPs improves fertility outcomes. While obesity can affect fertility, the test does not assess hormonal status, egg quality, or sperm parameters. Evidence is mechanistic/marketing. For fertility concerns, clinical tests (hormone panels, ultrasound) and medical consultation are essential. This consumer DNA test cannot replace diagnostic workup.
