Changes in Cryotolerance of Spermatozoa in Men with Teratozoospermia Under the Influence of Extracellular Vesicles from Donor Seminal Plasma Isolated by Depth Filtration.
Article in Life (Basel, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Currently, there is a need to improve the cryopreservation process for male gametes, especially for patients with low cryotolerance during sperm cryopreservation.
methodsThe content and size of donor extracellular vesicles (EVs) in seminal plasma (SP) were assessed using nanoparticle tracking analysis (NTA), CD marker analysis, and transmission electron microscopy (TEM). Patient ejaculates were exposed to cryopreservation with or without prior co-culture with SP EVs and were not exposed to cryopreservation. The interaction of SP EVs with spermatozoa was assessed by TEM. Apoptotic, necrotic and late apoptotic cells, and mitochondrial functional activity were detected by flow cytometry.
resultsNTA showed the highest concentration of SP EVs with a size of 80 nm, corresponding to small EVs. The binding of SP EVs to spermatozoa occurred along the entire plasma membrane, with an increased concentration of SP EVs at the neck and upper third of the sperm head. A significant increase in sperm motility was observed in the EVs co-culture group after cryopreservation/thawing. Flow cytometry showed a significant difference in the JC-1 Red/JC-1 Green ratio, indicating a higher mitochondrial membrane potential in the EVs exposure group.
conclusionsSP EVs have a protective function during human sperm cryopreservation.
