Source Hierarchy
Preferred sources include professional clinical organizations, government public-health agencies, regulators, systematic reviews, and peer-reviewed research.
- Official and clinical sources are favored for medical safety claims.
- Commercial, clinic, supplement, and affiliate sources are treated as lower-trust context unless independently supported.
- Every source should include a title, URL, description, and access date.
Evidence Grades
Claim-heavy pages should label evidence strength from strong guideline or systematic-review support through limited, mixed, or insufficient evidence.
Uncertainty
When evidence is mixed or indirect, ClaraFerti should preserve uncertainty and route personal decisions back to a clinician, pharmacist, fertility clinic, genetic counselor, lawyer, or other qualified professional as appropriate.
