Paternal diet before conception affects fetal growth and placenta development

Fathers' diets before conception can significantly impact fetal growth and placenta development, according to new mouse research. The study found that high-fat or low-protein diets in male mice altered key biological processes in the placenta after fertilization, potentially affecting nutrient exchange and later health. These findings suggest paternal nutrition is a vital, often overlooked, factor in early development, with researchers aiming for future human studies to provide practical advice.
