+1

Headline +1 is the strongest independent cluster (GONADAL_FUNCTION: Fertility). Other clusters and child mechanisms were not added. Human relevance is the relevance of the headline cluster, not the maximum relevance anywhere in the domain, and it is not multiplied into the score. No curated scientific findings are linked yet. The number is a seed assessment, not a literature count. Direction UNKNOWN. Confidence VERY_LOW. Human relevance H0. Supporting findings 0. Contradictory findings 0. Curation SEED_HYPOTHESIS.

Direction: Disruptive signal
Confidence: Very low
Human relevance: H0 · no meaningful human evidence
