Evidence check: Fertility Check | Fruchtbarkeits-Test in the context of Blutzucker

The Fertility Check (e.g., hormone panel, AMH) does not measure blood glucose levels. However, there is a well-established link between blood sugar regulation and fertility: insulin resistance and impaired glucose metabolism (e.g., in PCOS) can affect hormone profiles such as LH/FSH ratio, testosterone, and SHBG. A fertility test alone cannot replace dedicated blood glucose diagnostics (fasting glucose, HbA1c, oral glucose tolerance test). The evidence for the relevance of blood sugar in fertility is strong (clinical practice, guidelines), but the test itself does not assess this parameter. Without accompanying metabolic testing, its utility for evaluating blood sugar-related fertility issues is limited. Be cautious of marketing claims that present a fertility check as a standalone tool for assessing glycemic impact on fertility.
