Human semen as an early, sensitive biomarker of highly polluted living environment in healthy men: A pilot biomonitoring study on trace elements in blood and semen and their relationship with sperm quality and RedOx status
چکیده انگلیسی


- Trace elements in semen and blood discriminate people living in polluted areas.
- Seminal plasma is more sensitive than blood to redox status alteration.
- Lower sperm quality and antioxidant defenses associated to highly polluted area.
- In healthy males, semen is proposed as early biomarkers of environmental pollution.

The Campania region in Italy is facing an environmental crisis due to the illegal disposal of toxic waste. Herein, a pilot study (EcoFoodFertility initiative) was conducted to investigate the use of human semen as an early biomarker of pollution on 110 healthy males living in various areas of Campania with either high or low environmental impact. The semen from the “high impact” group showed higher zinc, copper, chromium and reduced iron levels, as well as reduced sperm motility and higher sperm DNA Fragmentation Index (DFI). Redox biomarkers (total antioxidant capacity, TAC, and glutathione, GSH) and the activity of antioxidant enzymes in semen were lower in the “high impact” group. The percentage of immotile spermatozoa showed a significant inverse correlation with TAC and GSH. Overall, several semen parameters (reduced sperm quality and antioxidant defenses, altered chemical element pattern), which were associated with residence in a high polluted environment, could be used in a further larger scale study, as early biomarkers of environmental pollution.
