Involvement of autophagy in germ cells in an experimental model of varicocele in rats before and after varicocelectomy.
Article in Pediatric surgery international, 2024. 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
introductionAutophagy, a catabolic process enabling cellular organelles and proteins' reuse for energy, has been observed in varicocele models, but the effect of surgical treatment on this process remains unknown. This study aims to assess autophagy in varicocele models undergoing surgical correction. MATERIALS AND
methodsTwenty-one adolescent male rats were induced with varicocele and divided into three groups: sham, varicocele, and varicocele with varicocelectomy. After 21 days, testicles were examined histologically for spermatogenesis (Jonhsen's score) and immunohistochemically for autophagy markers (LC3A, Beclin-1, Ambra-1, ULK-1, p62). Positive germ cells were quantitatively evaluated, and data were statistically analyzed (p < 0.05).
resultsHistological examination revealed significantly reduced Jonhsen's scores in varicocele compared to sham and varicocelectomy groups (p < 0.05). Expression of autophagy markers (LC3A, Beclin-1, Ambra-1, ULK-1, p62) was significantly higher in varicocele than sham and varicocelectomy groups (p < 0.05), and in varicocelectomy than sham (p < 0.05).
conclusionsVaricocele activates autophagy markers, with p62 potentially modulating autophagy despite being considered an inhibitor. While varicocelectomy improves histology, it doesn't fully inhibit autophagy, suggesting ongoing germ cell dysfunction despite treatment. This underscores varicocele's detrimental effects on germ cell functionality.
