Findings from Jacob Cleary’s masters project have been recently published in Environmental Pollution Journal. Jacob found a significant reduction in sperm count and sperm motility as well as fertilization efficiency in the third generation male medaka due to grandparental early life exposure to atrazine, a broad-spectrum herbicide used in the United States and other parts of the world. Transgenerational health effects are not caused by immediate exposure to toxicants but due to ancestral exposure. Looks like grandparent’s life style affects the health of current generation, and current generation exposure may affect the health of grandchildren two generations later. Mechanisms underlying these far reaching health effects of exposure are currently enigmatic.
