The effects of COVID-19 on semen parameter values in healthy males: a single-centre, retrospective study.
Article in PeerJ, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: To investigate the effects of the novel coronavirus disease 2019 (COVID-19) on spermatogenesis and the potential impact on patients with normal semen quality before a COVID-19 diagnosis. Methods: This retrospective study included 22 male patients (aged 18-48 years) diagnosed with mild COVID-19 Results: The mean age of the patients was 31.8 ± 5.9 years. An abnormality was detected in at least one parameter value in the post-COVID-19 semen analysis in nine patients (40.9%) whose semen quality was normal before COVID-19. When post-COVID-19 semen samples of the patients were divided into normal and abnormal groups, total sperm motility, progressive motility, and normal morphology were found to be significantly decreased, immotility significantly was increased, and semen pH tended to be more alkaline in the abnormal group. Conclusion: Even though the effects of COVID-19 on spermatogenesis are not fully understood, COVID-19 infection may have negative effects on semen quality and impair fertilization.
