The overlap between medical school, residency, and childbearing potential increases the likelihood a woman will pursue parenthood within her, or her partner’s, medical training. Parental leave benefits mothers, fathers, and infants. Adequate parental leave promotes physical recovery, mental health, infant bonding, improved breastfeeding, appropriate childhood immunization, and familial engagement. Despite the risks and benefits, the United States does not have national paid maternity, paternity, or parental leave requirements. Complicating matters for medical trainees, parental leave policies are not well-defined within the undergraduate (UME) and graduate medical education (GME) realms. Significant policy advancements are on the horizon for GME; however, medical schools are left without evidence to support policy formation.
