Semen Quality Following Long-term Occupational Exposure to Formaldehyde in China.

ABSTRACT:

Importance

The potential effects of long-term occupational exposure to formaldehyde (FA) on human semen quality is not clear.

Objective

To assess whether long-term occupational exposure to FA is associated with semen quality.

Design, setting, and participants

This population-based cohort study was conducted from June 1 to June 30, 2021, in Xi'an, China. Participants were adults aged 23 to 40 years who had lived in the study area for 24 months or longer. Data analysis was performed from September 1 to October 1, 2021.

Exposures

Long-term occupational exposure to FA was measured using a formaldehyde detector, and the FA exposure index (FEI) was calculated as follows: FEI = final concentration of FA (mg/m3) × work time during a workday (hour) × cumulative workdays
