Summary
This systematic review, published in the International Journal of Hygiene and Environmental Health, synthesises evidence from multiple primary studies examining the relationship between pesticide exposure — both occupational and residential — and human fertility in men and women. The review likely identifies associations between specific pesticide classes (e.g. organophosphates, organochlorines) and adverse reproductive outcomes, including reduced sperm quality, hormonal disruption, and impaired fecundability, though causal inference is complicated by heterogeneity in exposure assessment and study design across included studies. The paper provides a structured appraisal of the evidence base, highlighting gaps and methodological limitations relevant to reproductive epidemiology.
UK applicability
While the review draws on international evidence, findings are broadly applicable to UK contexts given shared concerns around pesticide regulation, occupational exposure among agricultural workers, and environmental contamination; the findings may inform UK regulatory assessments of agrochemical safety and support ongoing policy debates under post-Brexit pesticide approval frameworks.
Key measures
Fecundability odds ratios; sperm concentration, motility and morphology; time-to-pregnancy; serum reproductive hormone levels; miscarriage rates
Outcomes reported
The review examined associations between occupational and environmental pesticide exposure and human fertility outcomes, including measures of fecundability, sperm quality, hormonal profiles, and pregnancy rates across male and female populations.
