This research letter, published in JAMA Internal Medicine, investigates gender differences in mentor-mentee sponsorship experiences. Distinct from the advisory role of a mentor, sponsorship describes advocacy on behalf of a high-potential junior person by powerful senior leaders that is instrumental for career advancement in academic medicine. Any and specific sponsorship experiences were commonly reported by men although no gender differences were observed for perceptions of the mentor’s use of influence to support the mentee’s advancement or bringing the mentee’s accomplishments to the attention of important people. The letter goes on to discuss possibile reasons for differences (i.e. less powerful mentors, less active requests for sponsorships, etc.).
