Cross-species metabolic profiling of follicular compartments in obesity.
Article in Life medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Impaired fertility in obese women is closely associated with disruptions in follicular microenvironment homeostasis. However, the underlying metabolic signatures remain poorly characterized. In this study, we employed a high-fat diet induced obese mouse model and conducted comparative metabolomic analyses of granulosa cells, follicular fluid, and serum from obese mice and women. Our results revealed prevalent metabolic disturbances across species, including dysregulated amino acid metabolism, suppressed steroidogenesis, and impaired fatty acid β-oxidation. Notably, ceramide accumulation in granulosa cells and follicular fluid suggested an insulin-resistant follicular microenvironment. These findings indicate obesity-induced metabolic reprogramming in the follicular niche, highlighting conserved disruptions in energy metabolism and steroidogenic capacity. Overall, our data provide a metabolic framework to elucidate obesity-associated subfertility and suggest potential metabolic targets for diagnosing and treating reproductive disorders.
