Varicocele grade does not correlate with the severity of sperm DNA fragmentation levels nor with the amount of improvement in DNA fragmentation following varicocele repair.

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
Background: Varicocele is the most common correctable form of male infertility. Varicoceles have been established to result in worsened semen parameters as well as elevate sperm DNA fragmentation (SDF). There is data indicating that varicocele repair improves semen parameters and SDF, however; there is a paucity of data assessing the correlation of varicocele clinical grade with the severity of SDF and the amount of improvement in SDF with varicocele repair based on grade. The purpose of this study was to assess the difference in baseline sperm DNA fragmentation indices (DFIs) in infertile men with varicoceles based on the clinical grade of the varicocele and the amount of improvement in DFI following varicocele repair. Methods: A retrospective chart review was performed in men who presented for a fertility evaluation and were diagnosed with a clinical varicocele and underwent varicocele repair with preoperative and 3-month postoperative semen analyses with DFI testing. Results: There was no significant difference in the level of SDF based on the grade of varicocele, and there was not a significant correlation between the grade of the varicocele and the amount of improvement in SDF from baseline to 3 months after varicocele repair. Conclusions: When counseling infertile men undergoing varicocele repair for elevated SDF, the grade of varicocele may not impact the amount of improvement expected in SDF following repair, suggesting that varicocele patients may be counseled similarly on expectations for response regardless of varicocele grade.
