The influence of body mass index on oxidative stress markers in infertile men's semen parameters.
Article in Clinical and experimental reproductive medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveAlthough various studies have linked environmental toxins, mumps infections, alcohol consumption, and abnormal body mass index (BMI) to impaired semen quality, the precise causes of infertility remain unclear. This study investigates the impact of BMI on oxidative stress markers in semen analysis among infertile men, illuminating the role of oxidative stress in cases of unexplained infertility.
methodsIn this cross-sectional study, 280 patients exhibiting infertility symptoms were recruited. Comprehensive semen analysis was conducted, evaluating reactive oxygen species (ROS) levels, sperm plasma membrane lipid peroxidation via flow cytometry, total antioxidant capacity (TAC), and results from the sperm chromatin structure assay. Participants were categorized based on their BMI, facilitating comparisons between obese and non-obese individuals.
resultsBoth BMI and age significantly influenced male fertility, particularly in obese individuals. Strong correlations were identified between elevated BMI, increased ROS levels, and decreased TAC. The obese infertile group exhibited substantially lower TAC compared to controls, highlighting obesity's detrimental effect on antioxidant defenses. Furthermore, significant reductions in sperm count, motility, and normal morphology were observed, alongside an increase in non-motile sperm. These outcomes demonstrate the complex relationship among oxidative stress, BMI, and fertility, emphasizing the necessity for targeted interventions addressing obesity's effects on reproductive health.
conclusionThis study underscores the importance of managing obesity and understanding its impact on oxidative stress as essential components in improving reproductive outcomes among affected men.
