Is hsCRP useful for Fruchtbarkeit?

Whether hsCRP (high-sensitivity C-reactive protein) is useful for fertility requires a nuanced answer. hsCRP is a well-established marker of systemic inflammation. Chronically elevated levels (≥2 mg/l) have been associated in observational studies with reduced fertility in women (e.g., ovulatory dysfunction, endometriosis, poorer IVF outcomes) and in men (impaired sperm quality). However, hsCRP is not a specific fertility marker. The evidence is largely from observational studies; randomized controlled trials proving that lowering hsCRP causally improves fertility are lacking. Many factors (infections, smoking, obesity) can raise hsCRP, complicating interpretation. In the context of MyBody-X, hsCRP is not explicitly marketed as a fertility test, but as part of a general health check it can hint at inflammatory processes that may affect fertility. Its utility is limited: a normal hsCRP does not rule out fertility issues, and an elevated level is not direct proof of infertility. Practically, hsCRP can be a useful adjunct biomarker within a comprehensive fertility workup, not a standalone test. Evidence grade: human-moderate (observational studies, mechanistic plausibility).
