Dr. Myriam Afeiche of the Department of Nutrition at the Harvard School of Public Health in Boston and colleagues said men in sub-fertile couples presenting for evaluation at the Massachusetts General Hospital Fertility Center were invited to participate in an ongoing study of environmental factors and fertility.
