Daily News: Novel Study Correlates a Reduction in S***m Counts in Men with Neonicotinoid Insecticide Exposure
A study of neonicotinoid insecticides (NEOs) adds to the wide body of science on adverse reproductive health effects from pesticides and specifically correlates higher concentrations of NEOs and their metabolites in seminal plasma (semen fluid) with lower levels of s***m cells.
As the study, published in Frontiers in Endocrinology, reports: “Neonicotinoid insecticides (NEOs) are among the most widely used insecticides worldwide, yet their presence in seminal plasma and potential implications for male reproductive health remain poorly characterized. Urine—the conventional biomonitoring matrix—may not fully reflect concentrations in reproductive-relevant tissues, highlighting the need for direct seminal biomonitoring.”
ℹ️ Infertility is a global health concern and, according to the World Health Organization (WHO), approximately 1 in 6 people worldwide experience infertility during their life.
Eleven different neonicotinoids and their metabolites are detected in urine with a >75% detection frequency, while four compounds are identified in semen. The most notable neonicotinoid to have impacts on s***m concentration, total s***m count, and motility is imidacloprid, while mixtures of compounds also reveal a 27% reduction in s***m concentration.

To protect reproductive health, in men and women, the transition to organic agriculture and land management is imperative. Systemic pesticides like neonicotinoids are particularly threatening to humans and wildlife, such as pollinators, with their ability to be absorbed by crop plants and translocate throughout the plant’s vascular system and move into pollen, nectar, and guttation droplets. Contamination of neonics in food and water can be avoided with the adoption of the holistic solution of organic practices.
🎥 🔜 Join us NEXT WEEK for the launch of Beyond Pesticides' 2026 National Forum on October 21, 1-3:30pm ET, which brings us into conversation with the science—made simple—that we need to use as a tool for advancing changes required for a livable future. The failure of decision makers and policymakers to respond to the seriousness of the current pesticide-induced threats continues at our peril. The science, if widely discussed and understood, provides the impetus to adopt sustainable practices that are available to us!
