Evidence check: Insulin in the context of Fruchtbarkeit

Insulin plays a key role in metabolism and can affect fertility, especially in women with PCOS (Polycystic Ovary Syndrome). Insulin resistance leads to elevated insulin levels, which disrupt the hormonal axis and may impair ovulation. MyBody-X does not offer direct insulin measurement in its fertility-related tests; available hormone tests (e.g., testosterone) are often calculated and not validated for assessing insulin resistance. A fasting insulin level or HOMA-IR (calculated from fasting glucose and insulin) is clinically established, but a single test without medical interpretation is of limited value. The evidence linking insulin to fertility is human-moderate (mainly in PCOS), but for consumer tests it is mostly marketing. Caveat: No validated data in context. Consult an endocrinologist for fertility concerns.
