Examining the Relationship Between Polystyrene Microplastics and Male Fertility: Insights From an In Vivo Study and In Vitro Sertoli Cell Culture
Summary
This study found that polystyrene microplastics caused reproductive damage in male mice, disrupting the cells that support sperm development (Sertoli cells). The microplastics interfered with normal reproductive function in both live mice and cell cultures. These findings add to growing evidence that microplastic exposure could contribute to declining male fertility, a trend already observed in humans worldwide.
PS-MPs induced reproductive dysfunction in male mice provide new insights into PS-MPs-associated toxicity in mammals.

Polystyrene microplastics cause reproductive toxicity in male mice
Male mice exposed to polystyrene microplastics for six weeks showed significant reproductive damage, including reduced sperm count and motility, lower testosterone levels, and visible tissue damage in the testes. The microplastics caused oxidative stress and triggered cell death pathways in the reproductive tissue. These findings add to growing evidence that microplastic exposure could contribute to declining male fertility.
Reproductive toxicity of polystyrene microplastics: In vivo experimental study on testicular toxicity in mice
Researchers exposed mice to polystyrene microplastics and examined the effects on male reproductive function. They found that microplastic exposure significantly reduced viable sperm count, increased sperm abnormalities, and caused structural damage to testicular tissue, suggesting that microplastics may pose risks to male fertility.
Effects of polystyrene microparticles exposures on spermatogenic cell differentiation and reproductive endpoints in male mice
Researchers found that very small polystyrene microplastics (0.1 micrometers) accumulated in mouse testicular tissue and sperm-producing cells, leading to reduced sperm quality and impaired reproductive function. The particles triggered oxidative stress and disrupted the normal process of sperm cell development. This study adds to growing evidence that microplastic exposure could contribute to male fertility problems in humans, particularly from the smallest particles that can penetrate reproductive tissues.
Prenatal and postnatal exposure to polystyrene microplastics induces testis developmental disorder and affects male fertility in mice
Researchers exposed pregnant mice and their offspring to polystyrene microplastics from gestation through early life and found significant disruption to testicular development and male reproductive function. The exposed males showed reduced sperm quality, lower testosterone levels, and structural damage to testicular tissue. The study suggests that early-life microplastic exposure may have lasting effects on male fertility.

This journal issue summary highlights a study that exposed male mice to polystyrene microplastics through oral ingestion for 28 and 56 days. The researchers found significant decreases in sperm concentration, motility, and normal sperm proportion, along with increased inflammatory markers. When tested on cultured Sertoli cells (which support sperm development), the microplastics penetrated the cells and triggered inflammatory responses, providing evidence that microplastic ingestion can cause male reproductive dysfunction in mammals.
