Extracellular vesicles therapy alleviates cisplatin-ınduced testicular tissue toxicity in a rat model.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
purposeCisplatin is a commonly used chemotherapy agent effective against various cancers, however it induces significant gonadotoxicity and infertility due to its adverse effects on testicular function. The underlying mechanisms of cisplatin-induced testicular damage include oxidative stress and dysregulated autophagy. This study investigates the potential of extracellular vesicles (EVs) to mitigate cisplatin-induced testicular damage through their regenerative, antioxidant, and autophagy-modulating properties.
methodsIn the testicular toxicity model, thirty-two male rats were randomly divided into four groups (n = 8): control, EVs-only, Cis-only, and Cis + EVs. A single intraperitoneal dose of 7.5mg/kg cisplatin was administered on the first day. On the six day, the EVs treatment group received a single dose of EVs (8x107/100μl) intravenously. Animals were sacrificed on day eight. Testicular histoarchitecture was assessed via hematoxylin and eosin staining. Sperm parameters, including motility and count, were measured using light microscopy. Hormone levels (testosterone and inhibin) were determined via enzyme-linked immunosorbent assay (ELISA). Oxidative stress markers, such as glutathione peroxidase (GSH-PX), superoxide dismutase (SOD), catalase (CAT), and is a metabolite malondialdehyde (MDA), were quantified using colorimetric assays. Autophagy and steroidogenesis were evaluated through immunohistochemical analysis of Beclin-1, p62, LC3-2, SF-1, and StAR.
resultsCisplatin exposure caused significant testicular damage, characterized by reduced germinal epithelium and degeneration of seminiferous tubules (p < 0.001). These structural changes led to hormonal imbalances, as evidenced by declines in testosterone (p < 0.005) and inhibin (p < 0.001). Additionally, sperm motility (p < 0.05) and count (p < 0.001) were adversely affected. Immunohistochemical analysis revealed upregulation of autophagy markers (p < 0.001), indicating heightened autophagic activity, alongside downregulation of steroidogenic factors (p < 0.001), which contributed to impaired steroidogenesis. Elevated levels of malondialdehyde (MDA) (p < 0.01) and decreased activities of antioxidant enzymes-GSH-PX, SOD, and CAT (p < 0.001) pointed to increased oxidative stress as a contributing mechanism. In contrast, treatment with extracellular vesicles (EVs) significantly improved testicular histoarchitecture (p < 0.001) and restored hormonal levels toward normal (testosterone p < 0.005, inhibin p < 0.001). Furthermore, EVs reduced the expression of autophagy markers (p < 0.001) and enhanced the levels of steroidogenic factors (p < 0.05). Notably, MDA levels decreased (p < 0.001), while antioxidant activities increased (p < 0.001), suggesting a protective effect of EVs against oxidative stress.
conclusionEVs protect against cisplatin-induced reproductive toxicity by modulating oxidative stress and autophagy pathways, preserving testicular function and fertility. These findings suggest that EVs may be a promising therapeutic strategy for mitigating cisplatin's negative effects on reproductive health. Further exploration of dosing regimens and localized applications is recommended for improved efficacy.
