Scientists detect microplastics in amniotic fluid, effects on testicular aging

Two studies investigate microplastic presence or effects in female and male reproductive organs; small cohort study finds low number of microplastics to be present in human amniotic fluid besides the placenta; in vitro and mice in vivo study reports microplastics induce premature testicular aging and identifies underlying pathways

Researchers detect microplastics in human semen and heart

Four recent studies assess microplastics: in human semen, heart, from baby food containers, and suitability of in vitro models to investigate human health effects; find microplastics in six out of ten semen samples,find impacts on semen quality; samples from cardiac surgery patients contain microplastics in heart and surrounding tissue; billions of nano- and microplastics from plastic baby food containers; outline challenges and recommendation of studying plastic particles in vitro
