What to watch with Fertility Check and Abnehmen?

Combining a Fertility Check with a weight loss (Abnehmen) test – often via DNA or microbiome analysis – is marketed as a holistic approach, but the evidence is weak. Fertility checks may include hormones (FSH, AMH) or genetic variants (e.g., MTHFR), but these have limited predictive value for individual conception chances. Weight loss tests typically analyze SNPs like TCF7L2 or ADRB3, or gut bacteria, yet their effect on actual weight loss is small and inconsistent in human studies. No RCT shows that acting on these markers improves fertility or weight outcomes compared to standard lifestyle advice. The main risk is overinterpretation: a consumer test result might lead to unnecessary dietary restrictions or false reassurance. For fertility, proven factors include age, cycle regularity, sperm quality, and lifestyle (diet, stress, sleep). For weight loss, energy balance and behavioral change remain key. Companies like MyBody-X explicitly state their tests are not diagnostic. Therefore, watch out for exaggerated claims and always consult a specialist (gynecologist, endocrinologist) before investing in such combo tests.
