News | Declining Sperm Counts: Potential Risks of Microplastic Exposure
A new study links exposure to microplastics, particularly polytetrafluoroethylene (PTFE), with reduced sperm quality. The finding has raised concern about the effects of environmental pollutants on male fertility.
Effects of Microplastics on Male Fertility
Published in eBioMedicine, the study was conducted across several research sites in China. Researchers analyzed semen and urine samples from 113 men in different regions to assess the presence of various microplastics and their effects on sperm quality. Microplastics, especially PTFE, were significantly associated with lower sperm counts and motility.
Background
Microplastics are plastic particles less than 5 millimeters in diameter and are widespread in the environment. They have been detected in several human tissues, including the liver, lungs, placenta, and semen. Research suggests that people ingest substantial numbers of microplastic particles each day, averaging 5,186 particles per year in children and 1,482 in adults. Microplastics enter the body through food, air, and skin absorption and may pose risks to health, particularly male fertility.
Results
Researchers collected semen and urine samples from 113 men aged 24 to 58 and detected several microplastics, including polystyrene (PS), polyethylene (PE), polyvinyl chloride (PVC), and PTFE. PTFE was detected in 55% of participants and was closely associated with reduced total sperm count and motility. Men exposed to six types of microplastics had significantly lower total sperm counts and progressive motility than those exposed to fewer types.
Sources and Potential Health Risks
The study also identified PTFE from nonstick cookware as a potentially important source of exposure affecting male fertility. Common household items may therefore contribute to microplastic exposure and affect male reproductive health.
Future Research
The study highlights potential reproductive risks from microplastic pollution and provides epidemiological evidence for further research into the relationship between exposure and sperm dysfunction. Researchers called for additional studies on long-term reproductive effects and effective prevention and treatment approaches.
