Five studies on microplastic presence and effects on central nervous system (CNS) and reproductive organs; study finds microplastics of some but not all polymer types enter human CNS, especially after blood-brain barrier impairment; review concludes microplastics induce neurotoxicity; scientists demonstrate presence of microplastics in female reproductive tissue and male para-tumor and tumor prostate samples; associate microplastic presence with sperm dysfunction

Recent studies show that MNPs can negatively impact reproductive health
Studies confirm micro- and nanoplastics (MNPs) in human endometrial tissue, amniotic fluid, placentas, and feces of pregnant people; MNP presence in the endometrium is linked with recurrent miscarriages in humans, apoptosis in organoids, and reduced fertility in mice; higher MNPs exposure from seafood and bottled water consumption
Mapping microplastics in the male reproductive system
Study provides an in-depth look at microplastics in the male reproductive system, analyzes human and mouse samples to chart concentrations and polymer types; finds microplastics in all human testes samples and majority of semen samples; larger plastic particles may get trapped in testis, leading to higher concentrations; identifies correlation between urbanization, home-cooked meals, and body scrub used to microplastics concentration
