Identifying critical windows of air pollution exposure and semen quality: A cross-sectional study in Chinese fertile men.

ABSTRACT:

Background

Although human studies on the hazard that air pollution represents to male reproductive health, there are wide variations in exposure concentration, key components, semen quality indicators and the identification of susceptible exposure windows. The study aimed to further explore the relationship between air pollution and semen quality and the more accurate sensitive exposure windows.

Methods

We investigated a cross-sectional study consisting of 1554 fertile men from Nanjing, China and evaluated their exposure to PM₁₀, PM_2.5, CO, SO₂, NO₂ and O₃ in the air. Multiple linear regression was utilized to estimate the correlation between weekly air pollution exposure and semen quality, as well as weighted quantile s
