A father's health before conception may be a bigger factor in child development than previously thought, according to a growing body of research.
"We want to understand how the memory of paternal alcohol exposure transmits to the children and then how it predisposes them to birth defects and chronic disease later in life."

Dr. Michael Golding, a professor at the Texas A&M College of Veterinary Medicine and Biomedical Sciences, is investigating how alcohol exposure alters biological signals in sperm, ultimately affecting the development and metabolism of offspring.
New Funding
The National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH), has awarded a $2.9 million grant to support this research. The funding, bolstered by Texas A&M AgriLife Research, will allow Golding and his team to expand their investigation into how parental alcohol exposure may contribute to chronic disease, accelerated aging, and developmental disorders in children.
Research Focus
This study builds upon previous work examining the link between paternal alcohol exposure and fetal growth restriction and birth defects.
A major focus of the research is the mitochondria—the structures within cells responsible for producing energy. Golding's team hypothesizes that alcohol-related stress alters molecular signals in sperm, which in turn disrupts mitochondrial function in the offspring. This disruption may accelerate aging and increase the risk of developing disease.
"We know now, even from human clinical studies, that male alcohol use has an adverse effect on child health and development."

Broader Implications
Golding notes that the findings from this research could help identify warning signs earlier and guide interventions for individuals affected by fetal alcohol spectrum disorders (FASD).
He also suggests that this work may eventually provide insight into how other environmental stressors—such as microplastics and industrial chemicals—influence reproductive health and disease risk across generations.
