Behavioral endocrinology of mammalian fatherhood

Abstract

Mammalian fatherhood involves a muted version of the maternal experience. In spite of previous assumptions to the contrary, hormones influence mammalian paternal behavior. Naturally paternal males experience dynamic changes in the same hormones involved in maternal behavior and these hormones have access to the same brain pathways. Men becoming fathers for the first time are similar to their female partners too. These recent studies are still correlational, but promise to illuminate maternal behavior and to biologically validate the experiences of involved fathers.
