This week on the podcast I speak with Dr. Anna Machin. Dr. Machin is an anthropologist focusing on the roles fathers play in a child's life as well as the biological changes that occur when a man becomes a father. We discuss topics ranging from why your testosterone drops as a man during childbirth, the main roles of fathers in a child's life, and how different cultures treat fatherhood.
