Dad's Preconception Drinking Alters Offspring Mitochondria, Study Finds
Texas A&M researchers, backed by a $2.9 million NIH grant, are investigating how a father's alcohol consumption before conception can imprint non-genetic signals in sperm that disrupt offspring mitochondrial function, potentially leading to birth defects, chronic disease, and accelerated aging, while exploring interactions with maternal exposure and implications for other environmental stressors.
