Prevalence and implications of microplastic contaminants in general human seminal fluid: A Raman spectroscopic study

Microplastics were detected in all 40 semen samples from men in the general population with no occupational plastic exposure, with an average of 2 particles per sample and polystyrene being the most common type. Sperm exposed to different plastic types showed varying motility, suggesting that the kind of microplastic present may matter for male fertility.

Raman Microspectroscopy evidence of microplastics in human semen

Researchers found microplastic fragments in six out of ten human semen samples from men in a polluted region of southern Italy, identifying common plastics like polypropylene, polyethylene, and PET. The study proposes that microplastics enter semen through the reproductive tract after being ingested or inhaled, raising concerns about potential effects on male fertility.

Detection and characterization of microplastics in the human testis and semen

Researchers detected microplastics in both human testis tissue and semen samples for the first time, finding an average of about 12 particles per gram in testis and different plastic types in semen. Polystyrene dominated in testis while polyethylene and PVC were most common in semen, providing critical evidence that microplastics can pollute the male reproductive system and raising concerns about potential fertility impacts.

Microplastic presence in boar semen: potential risks for reproductive health

Researchers detected microplastic particles in boar semen samples, raising questions about the effects of microplastic contamination on sperm quality and reproductive health in both animals and potentially humans.
