Altered microbiota profile in seminal vesicles of men presenting with refractory hematospermia.
Article in Molecular biology reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundCurrently, no recognized evidence is known about the bacterial communities found within seminal vesicles (SV) of men presenting with refractory hematospermia. METHODS AND
resultsFifteen male patients with refractory hematospermia or anejaculation were enrolled, and 15 SV-Infection (SV-In) samples from SV with hemorrhage and/or stones, 11 SV-Control (SV-C) samples from SV with non-infection, and 14 Urine (Urine) samples from posterior urethra were obtained via transurethral seminal vesiculoscopy. Then the high-throughput 16 S rRNA gene sequencing method was performed to characterize the microbiota profile. Finally, a total of 1535 operational taxonomic units (OTUs) were found, 1295 OTUs were shared across three groups, 7 OTUs, 45 OTUs, and 48 OTUs were unique to SV-C group, SV-In group, and Urine group, respectively. The 5 top bacterial phyla (mean relative abundance) in all samples were Firmicutes (52.08%), Bacteroidetes (21.69%), Proteobacteria (12.72%), Actinobacteria (9.64%), and Fusobacteria (1.62%), the 5 top bacterial genera in all samples were Bacteroides (9.13%), Lactobacillus (5.38%), Bifidobacterium (5.35%), Faecalibacterium (5.10%), and Allobaculum (3.34%), of which Bifidobacterium had the highest level in SV-C samples and had a significant difference (P < 0.05) across all groups. Differential analysis showed genera Leuconostoc and LachnospiraceaeFCS020group were identified as biomarkers in the SV-In microbiota.
conclusionAltered microbiota composition in seminal vesicles is related to refractory hematospermia in men, and the distribution of genus Leuconostoc or LachnospiraceaeFCS020group within seminal vesicles may interact with hematospermia. This study provides clues for the diagnosis and treatment of this urologic disorder.
