Dioxin, an endocrine disruptor, induces long term effects on DNA methylation in men after in-utero exposure

Key Points

• The study aims to explore the long-term impacts of in-utero dioxin exposure on DNA methylation and related health effects.
• Examined historical data from children exposed to dioxin in Seveso.
• Investigated the relationship between dioxin levels and semen quality.
• Assessed alterations in thyroid homeostatic mechanisms.
• Exposure to dioxin linked to long-term reduction in semen quality.
• Changes in thyroid hormone regulation were noted.
• Dioxin serum levels associated with observed effects were significantly lower than expected.
