Paternal Lifestyle Impacts Child Development Outcomes

7.2
A recent study published in The Lancet finds that men's preconception behaviors — including alcohol use, smoking, diet, obesity, and mental health — influence sperm quality and are associated with increased congenital abnormalities and poorer child development. The authors note global sperm counts have fallen by over half in recent decades and call for expanded preconception education, mental-health support, and improved healthcare access for prospective fathers.
