Due to the problematic degradation properties of plastics, the decomposition of plastic results in the formation of numerous microplastics, less than 5 mm in diameter. These microplastics enter the soil and the ocean, eventually passing through the air, water, or food chain back to the human body and harming human health. In the last 80 years, male semen analysis parameters have shown a significant decline. No studies examined the relationship between human microplastic exposure and male infertility. The article reviewed the relevant animal experimental research literature in recent years and calculated that the minimum human equivalent dose of microplastics leading to abnormal male semen quality is 0.016 mg/kg/d. The literature comparison found that...
