Can Fitness | LifestyleCheck help with Fruchtbarkeit?

The provided contexts do not directly address fertility. 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.
