Air pollution has been suggested to affect semen quality, but the evidence is still contradictory. To assess whether any differences occur in conventional sperm parameters of men life-long resident in low, middle-low, middle, and high industrial density zones in the province of Messina. We retrospectively analyzed the conventional sperm parameters of patients to whom the sperm analysis was requested during their female partner counseling for infertility in an assisted reproductive technique (ART) center. A total of 184 men were enrolled. Total sperm count was higher in patients living in low and middle-low industrial density areas compared with that of men living in middle and high ones (123.5 ± 146.8 vs. 80.7 ± 92.7 mil/ejaculate, p < 0.05). No difference was found for sperm concentration (37.2 ± 49.7 vs. 30.5 ± 37.2 mil/mL), progressive motility (15.4 ± 19.8% vs. 14.2 ± 18.4%), total motility (62.3 ± 20.5 vs. 58.4 ± 19.9 mil/mL), and normal forms (2.7 ± 1.5 vs. 2.3 ± 3.0 mil/mL). These results add further evidence to findings from Sicilian population. Effective control of air pollution should be accomplished to prevent its negative impact on human reproductive health.
空气污染被认为会影响精液质量，但证据仍存在矛盾。为了评估在墨西拿省低、中低、中和高工业密度区居住的男性的常规精子参数是否存在差异。我们回顾性分析了在辅助生殖技术（ART）中心因女性伴侣不孕而接受精液分析的患者的常规精子参数。共纳入 184 名男性。与居住在中、高工业密度区的男性相比，居住在低、中低工业密度区的男性总精子计数较高（123.5±146.8 与 80.7±92.7 mil/ejaculate，p<0.05）。精子浓度（37.2±49.7 与 30.5±37.2 mil/mL）、前向运动精子百分率（15.4±19.8%与 14.2±18.4%）、总运动精子百分率（62.3±20.5 与 58.4±19.9 mil/mL）和正常形态精子百分率（2.7±1.5 与 2.3±3.0 mil/mL）无差异。这些结果为西西里岛人群的研究结果提供了进一步的证据。应采取有效措施控制空气污染，以防止其对人类生殖健康产生负面影响。
