Abstract

Objective: This study aimed to explore the correlation between ambient particulate matter 2.5 (PM2.5) concentration and sperm quality among northern Thai men exposed to the seasonal air pollution from the agricultural burning process.

Methods: The demographic data and semen analysis of Thai men living in Chiang Mai, Thailand, who visited the infertile clinic were collected. The correlation test between the monthly amount of PM2.5 and sperm quality was carried out.

Results: From 2017 to 2021, 1,109 Thai men visited the Infertile Clinic. The correlation test between PM2.5 and sperm quality in years with a better climate revealed a weak positive correlation between the mean PM2.5 and percentage of progressive motile sperm and normal morphology (r=0.08, p=0.05 and r=0.1, p=0.02). However, there was a negative correlation between the mean PM2.5 and sperm concentration, progressive motility and normal sperm morphology during the years with a higher amount of ambient PM2.5, and especially PM2.5 exposure 3 months before semen collection (r=-0.12, p=0.01, r=-0.11, p=0.003, r=-0.15, p=0.004).

Conclusions: Exposure to a high amount of PM2.5 air pollution negatively affects sperm quality.

环境 PM2.5 暴露对泰国北部精子质量的不同影响。

研究目的本研究旨在探讨受农业焚烧过程中产生的季节性空气污染影响的泰国北部男性的环境颗粒物 2.5（PM2.5）浓度与精子质量之间的相关性：方法：收集了居住在泰国清迈、到不孕不育诊所就诊的泰国男性的人口统计学数据和精液分析。结果：从2017年到2021年，共有1,000名泰国男性在清迈不孕不育诊所就诊：2017年至2021年，共有1109名泰国男性前往不孕不育诊所就诊。在气候较好的年份，PM2.5与精子质量之间的相关性检验显示，PM2.5的平均值与进步运动精子和正常形态精子的百分比之间存在微弱的正相关性（r=0.08，p=0.05和r=0.1，p=0.02）。然而，在环境 PM2.5 较高的年份，尤其是精液采集前 3 个月接触 PM2.5 的年份，PM2.5 平均值与精子浓度、活动力和正常精子形态之间呈负相关（r=-0.12，p=0.01；r=-0.11，p=0.003；r=-0.15，p=0.004）：暴露于大量 PM2.5 空气污染中会对精子质量产生负面影响。
