Age-related changes in the cytoplasmic ultrastructure of feline oocytes.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
This study elucidates the impact of aging on the cellular architecture of feline oocytes, with a particular emphasis on organelles essential for fertilization and embryo development. Using transmission electron microscopy (TEM), the research compares oocytes from prepubescent, cycling adult, and aged cats, revealing notable differences in the arrangement of key structures, particularly mitochondria, lipid droplets, and vacuoles. Oocytes from adult donors are at their metabolic peak, demonstrating a higher concentration of mitochondria near lipid droplets, supporting efficient energy metabolism. In contrast, younger and older oocytes exhibit larger lipid droplets and reduced mitochondrial density, indicative of diminished metabolic activity. These findings not only underscore the necessity of selecting an optimal donor age for in vitro fertilization but also suggest potential biomarkers for oocyte quality assessment. This novel insight offers promising strategies to enhance reproductive success, improve assisted reproduction outcomes, and support feline conservation efforts.
