What to watch with CRP Entzündung and fertility?

CRP (C-reactive protein) is a non-specific marker of inflammation. Elevated levels may indicate systemic inflammation that can affect fertility—for example in endometriosis, PCOS, or chronic infections. However, CRP alone is not a direct fertility marker. The evidence for a causal link is weak; it is based on observational data. Genetic variants like rs1205 have only a small effect on baseline CRP. Lifestyle factors (obesity, smoking, poor diet, inactivity) are far more influential. An anti-inflammatory diet (omega-3, fiber, fermented foods) can lower CRP. Caution: a single CRP value does not reveal the underlying cause. If CRP is persistently high alongside fertility issues, medical workup is warranted (e.g., for endometriosis, thyroid function, infections). Genetic testing for CRP SNPs has limited clinical utility—a blood test is more actionable. Evidence: human-observational/mixed.
