Isolation of CD63-positive epididymosomes from human semen and its application in improving sperm function.
Article in Journal of extracellular vesicles, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Extracellular vesicles (EVs) are highly heterogeneous, and different EV subpopulations from various origins mediate different biological effects. The separation of different subpopulations of EVs from mixtures is critical but challenging. Epididymosomes are secreted by the epididymal epithelium and play a key role in sperm maturation and function. However, limited access to human epididymal tissue and epididymal fluid has hampered further study of epididymosomes and their potential clinical applications. Here, we established a novel strategy based on flow cytometry sorting to isolate human CD63-positive epididymosomes from ejaculate. We identified CD52, a membrane-located protein expressed exclusively in the epididymis, as the sorting marker for human epididymosomes. Then, CD63-positive epididymosomes were isolated from human semen using a flow cytometry sorting instrument and concentrated. Additionally, we observed that isolated CD63-positive epididymosomes improved sperm function more than other CD63-positive seminal EV subpopulations did, demonstrating the successful isolation of a subpopulation of epididymosomes from human semen and their potential application in the clinic.
