The yield of microscopic varicocelectomy in men with severe oligospermia.
Article in Urology annals. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
introductionVaricocele is detected in 35%-50% of men with primary infertility and up to 81% with secondary infertility. Various studies have shown that varicocele is related to testicular hypotrophy and impaired spermatogenesis. The effect of varicocelectomy in mild-to-moderate male factor infertility has been well reported. However, only a few studies addressed the impact of varicocelectomy in severe oligospermia.
methodsWe included 45 patients with severe oligospermia (<5 million/mL) who underwent microsurgical varicocelectomy between May 2014 and November 2017. Results of semen analysis taken at 6 months after varicocelectomy were compared and patients were divided into responders and nonresponders. Chi-square was used to compare the preoperative and postoperative sperm count, motility, and volume.
resultsAfter 6 months only one patient was found to be a responder with a pre- to post-operative motility of 45%-74% and a sperm concentration of 1 million/mL to 28.1 million/mL. There was a significant improvement in the mean sperm concentration after varicocelectomy which improved from 1.31 million/mL to 5.32 million/mL. However, a significant decrease in sperm motility was noted which decreased from 35.62% to 28.64% postoperatively. Postoperative semen volume increased from 2.56 mL to 3.19 mL, but this difference was not found to be statistically significant (
conclusionThe magnitude of improvement after microsurgical varicocelectomy for severely oligospermic patients is less profound than reported in mild male factor infertility.
