Does outdoor air pollution cause poor semen quality? A systematic review and meta-analysis.
Synthesis in BMC urology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
introductionIt is hypothesized that air pollutants could be associated with semen parameters. This systematic review and meta-analysis of observational studies was conducted to reach a firm conclusion regarding the possible association between outdoor air pollution and semen parameters among the adult population.
methodsPubMed, Scopus, and ISI Web of Science were systematically searched using the text keywords and MeSH terms, including "air pollution" and "semen parameters,". The population, Intervention, Comparison, and Outcome (PICO) framework was used as follows: P (Adult men), I (Individuals with the highest exposure to the air pollutants), C (Individuals with the lowest exposure to the air pollutants), O [Semen parameters, including semen volume, total sperm count, sperm concentration, total motility, progressive motility, normal morphology rate, and DNA fragmentation index (DFI)]. The overall effect was presented as a weighted mean difference (WMD) and 95% confidence interval (CI) analyzed via a fixed (inverse-variance) or random (DerSimonian-Laird) weighted model. Low, moderate, and high heterogeneity were defined as I
resultsSeventeen studies covering 24,065 participants were enrolled in this systematic review and meta-analysis. Higher exposure to outdoor air pollution was associated with significant decreases in semen volume (WMD: -0.13 mL; 95% CI, -0.21 to -0.05; P = 0.001; I
conclusionBased on the results, it can be stated that air pollution can impair sperm parameters. Further prospective cohort studies are needed to illuminate this issue and clarify the underlying mechanisms.
