Triclocarban impacts human sperm motility by inhibiting glycolysis and oxidative phosphorylation.

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
abstractTriclocarban (TCC) is a broad-spectrum antimicrobial widely used in various personal care products, textiles, and children's toys. TCC has potential reproductive and developmental toxicity in animals. However, little is known regarding the effect of TCC on human sperm function. In this study, an in vitro assay was used to investigate the effects of TCC on normal human spermatozoa and the possible underlying mechanisms involved. Semen from healthy male donors was collected and cultured in complete Biggers, Whitten and Whittingham (BWW) and low-sugar BWW media, followed by treatment with TCC at concentrations of 0, 0.1 µmol l -1 , 1 µmol l -1 , 10 µmol l -1 , and 100 µmol l -1 for 4 h. TCC was found to reduce the sperm total motility and progressive motility. Moreover, the sperm kinematic parameters, straight-line velocity (VSL), average path velocity (VAP), and curvilinear velocity (VCL) were affected in a dose-dependent manner. After treatment with TCC at the lowest effective concentration of 10 µmol l -1 , TCC caused a significant decrease in mitochondrial adenosine triphosphate (ATP) production and mitochondrial membrane potential (MMP) and a significant increase in reactive oxygen species (ROS), similar to the observations with the positive control carbonyl cyanide 4-(trifluoromethoxy) phenylhydrazone (FCCP), suggesting that TCC may decrease sperm motility by affecting the oxidative phosphorylation (OXPHOS) pathway. In a sugar-free and low-sugar BWW culture environment, TCC enhanced the damaging effect on sperm motility and ATP, MMP, and lactate decreased significantly, suggesting that TCC may also affect the glycolytic pathway that supplies energy to spermatozoa. This study demonstrates a possible mechanism of TCC toxicity in spermatozoa involving both the OXPHOS and glycolysis pathways.
