Myths vs facts: Glukose and Fruchtbarkeit

A common myth is that sugar or glucose directly causes infertility. Fact: Glucose is the body's primary fuel, essential for egg maturation and sperm production. However, impaired glucose regulation – such as insulin resistance or diabetes – can harm fertility, especially in PCOS (Polycystic Ovary Syndrome), where high insulin disrupts hormones and ovulation. The myth 'sugar kills sperm' lacks scientific support; moderate carbohydrate intake is not harmful. What matters is overall metabolic health: obesity, inflammation, and metabolic syndrome have stronger negative effects than isolated glucose intake. Direct-to-consumer tests (like MyBody-X) cannot diagnose fertility issues – they may only indicate risk variants in genes like LEPR (leptin receptor), linked to satiety and energy balance. The evidence for individual prediction is weak. Bottom line: Glucose itself is not a fertility poison, but dysregulated glucose metabolism can impair fertility. Those trying to conceive should focus on balanced nutrition and medical evaluation, not myths.
