Numerous studies indicate that overweight (especially visceral obesity), physical inactivity, smoking, excessive alcohol intake, and poor diet can impair fertility in both women and men. In women, these factors disrupt hormonal balance (e.g., insulin resistance, LH/FSH ratio) and ovulation; in men, they reduce sperm quality. The effects are moderate but clinically meaningful. However, most data come from observational studies, so causality is not always clear. Genetic variants like FTO (rs9939609) have a small but measurable impact on body weight, which may indirectly affect fertility – but the direct effect on fertility is weak. MyBody-X tests provide indications, not diagnoses. A healthy lifestyle (balanced diet, moderate exercise, normal weight, no smoking) is the most important modifiable factor. The evidence strength is rated as 'human-moderate' because randomized controlled trials on fertility are challenging and ethically complex. In summary: lifestyle changes can improve fertility, but individual genetic and medical factors also play a role.","area":"gesundheit","canonical_id":"gesundheit:canonical-ce07cc76cb81944537a77321","id":"public-c107e42ab0b292bc8a25ff9f","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: Fitness | LifestyleCheck in the context of Fruchtbarkeit","score":32.22264715,"snippet":"The evidence linking fitness and lifestyle to fertility is primarily human-observational and mechanistic.

However, it is well established that lifestyle factors such as diet, exercise, weight, stress, and sleep can influence fertility in both women and men. Overweight or underweight, smoking, excessive alcohol consumption, and intense endurance exercise may impair fertility, while moderate physical activity and a balanced diet are beneficial. Evidence comes from large observational studies and clinical interventions. Nevertheless, individual responses vary; if you are trying to conceive, medical evaluation is essential. A DNA test alone cannot reliably predict fertility. The contexts show that single gene variants (e.g., MTHFR, FTO) have small effects and lifestyle matters more. Therefore, a fitness and lifestyle check can help identify modifiable risk factors but should not replace professional medical advice.","area":"gesundheit","canonical_id":"gesundheit:canonical-950a13b290b296868052e00b","id":"public-c0495c46c8b5368a17bfdedf","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Can Fitness | LifestyleCheck help with Fruchtbarkeit?","score":31.13059325,"snippet":"The provided contexts do not directly address fertility.
