JOEM: Occupation and Semen Parameters in a Cohort of Fertile Men (October 2022)

Pdf Summary

This study examined the association between occupation and semen parameters in a cohort of fertile men. The researchers used the data from the Study for Future Families, which included semen samples and occupational information from 680 men. They assessed the associations of occupation and workplace exposures with semen volume, sperm concentration, motility, and morphology using statistical modeling. <br /><br />The results showed that lower sperm concentration and motility were observed in installation, maintenance, and repair occupations. These occupations were also associated with higher exposure to lead, pesticides, and solvents, which are known reproductive toxicants. Working with lead for more than 3 months was specifically linked to lower sperm concentration, as well as lead exposure outside of work.<br /><br />The findings suggest that exposure to lead, pesticides, and solvents may contribute to reduced sperm quality in fertile men. This information can help identify occupations where protective measures should be implemented to reduce the risk of male reproductive toxicity. Occupational exposures are important factors to consider in understanding male reproductive dysfunction, and further research is needed to explore the effects of different workplace exposures on male fertility.
