Abstract Background Limited studies have explored the association between gaseous pollutant exposures and male reproductive outcomes, findings remained inconsistent. Objectives To evaluate potential pollutants semen quality within different exposure windows. Materials Methods We adopted data of 1852 subjects who attended Reproductive Medicine Center Renmin Hospital at Wuhan University during January 1st, 2013, to August 3rd, 2015. A generalized linear model was employed assess relationship each variable sperm parameters in Results SO 2 with lag 0–90 days significantly associated decreased concentration (β: −1.362; 95% CI : −1.844, −0.879), count −2.979; −4.267, −1.691), PR −0.551; −0.710, −0.393). Similar trends were observed for three other key periods (lag 0–9, 10–14, 70–90 days). NO also −0.517; −1.006, −0.027), −1.914; −3.214, −0.615), −0.264; −0.425, −0.102). No ejaculate volume any window. Discussion Conclusion Our study indicated a strong adverse effect on outcomes development. Gaseous pollution appeared be more detrimental initial phase spermatogenesis.
