Perilous effects of polystyrene fragments on male reproductive system and tenable directives of remediation
Summary
This review examines the effects of polystyrene micro- and nanoplastics on the male reproductive system, focusing on signaling mechanisms and potential remediation strategies. Researchers found that these small plastic particles can cross biological barriers and disrupt normal reproductive physiology, contributing to fertility issues. The study highlights significant gaps in the research compared to studies on female reproductive effects and points to bioremediation using microorganisms as a potential mitigation approach.
Indiscriminate use of polystyrene (PS) plastics has posed a major problem for its disposal and recycling on one hand, while on the other hand, fragmentation of these into micro/nano compounds threatens the living world by its toxic effect. The small sized particles can be present in any ecosystem and pose threat to the living world there. The unique properties of these small-scale fragments allow them to cross the barriers of human bodies and affect the vital organ system, altering the normal physiological parameters. Male reproductive system is highly affected by these micro/nanoplastics which leads to infertility and other physiological complications. Smaller number of literatures has been reported in this field in comparison to female reproductive system. The signaling mechanism of polystyrene micro/nanoplastics (PSMP/NPs) have been discussed in this review. There are lacunae in this regard which have been addressed very specifically. Many reports of biodegradation processes have been put forward, but not without any additional hazards. This review puts together the existing literature on the effect of PSMP/NPs on mammalian male reproductive system, throws light on the possible bioremediation methods using microorganisms, and highlights the unattended areas of study so that the future research finds a way for these problematic aspects.

Can Mammalian Reproductive Health Withstand Massive Exposure to Polystyrene Micro- and Nanoplastic Derivatives? A Systematic Review
This systematic review examined how polystyrene micro- and nanoplastics affect reproductive health in mammals. The evidence from animal studies shows these particles can cause oxidative stress, inflammation, and hormonal imbalances in reproductive organs, raising concerns about potential effects on human fertility.
Impact of polystyrene microplastic exposure at low doses on male fertility: an experimental study in rats
Researchers exposed adult male rats to varying doses of polystyrene microplastics and found dose-dependent declines in semen quality along with disrupted reproductive hormone levels. Higher doses caused increased oxidative stress, mitochondrial damage, and inflammatory responses in testicular tissue. The study suggests that even relatively low doses of microplastic exposure may have adverse effects on male reproductive health in animal models.
Adverse effects of microplastics and nanoplastics on the reproductive system: A comprehensive review of fertility and potential harmful interactions
This review summarizes how microplastics and nanoplastics can harm both male and female reproductive systems by disrupting hormone signaling, damaging sperm and egg cells, and causing inflammation in reproductive tissues. Smaller nanoplastics are especially concerning because they can cross biological barriers more easily and reach the testes and ovaries. With global infertility rates rising, the authors highlight environmental plastic exposure as a factor that deserves more research attention.
Effects of micro(nano)plastics on the reproductive system: A review
This review summarizes research on how micro and nanoplastics affect the reproductive system in both animal studies and cell experiments. Evidence indicates these particles can cross biological barriers, accumulate in reproductive organs, and disrupt hormones, egg development, and sperm quality. While human studies are still limited, the animal data suggests microplastic exposure may be a meaningful concern for reproductive health.
Adverse effects and potential mechanisms of polystyrene microplastics (PS-MPs) on the blood-testis barrier
This review examines how polystyrene microplastics damage the blood-testis barrier, a critical structure that protects developing sperm cells from harmful substances. Microplastics can break down this barrier through oxidative stress, inflammation, and disruption of gut bacteria, allowing pollutants and immune cells to enter the reproductive system. These findings suggest that microplastic exposure may contribute to declining male fertility, a trend observed globally in recent decades.
