中国成年男性的环境细颗粒物成分和精液质量

暴露于环境细颗粒物（PM）与精液质量的降低有关，但PMCONSTITENTENTENTENT和精液质量之间的关系却不清楚。 We recruited 27,824 adult men attending an infertility clinic in Wuhan, China, between 2014 and 2020. We used a four-dimensional spatiotemporal deep forest model to estimate concentrations of PMmass and its chemical constituents, including organic matter (OM), black carbon (BC), sulfate (SO), nitrate (NO), ammonium (NH), and chloride (Cl).我们使用线性重新SSION模型估算PMMASS及其成分与各种精子参数之间的关联。 Exposure to PMwas associated with a reduction in sperm quality, with a percent change of - 5.69% (95% confidence interval [CI]: -8.53%, -2.85%) for sperm density, - 15.09% (95% CI: -22.24%, -7.94%) for sperm total count, - 1.63% (95% CI: -2.36%, -0.91%) for sperm精子总运动性的渐进运动性和-2.30％（95％CI：-3.04％，-1.55％）。在特定成分中，与这四个精液质量参数的降低相关的OM，BC，CL或NOWAS暴露。在受教育程度较低的老年人或个人中，该协会更为明显。我们的发现表明，PMMASS和每个成分与成年男性精液质量降低有关。
