Diet-Induced Changes in GEnetic Material

Description

This is a pilot study in 10 men to test the hypothesis that perturbations in substrate flux and the circulating metabolic and pro-inflammatory milieus during a high-fat diet paradigm will modulate DNA methylation of genes in sperm associated with obesity and cardiometabolic dysfunction.
