Dr. Brannigan’s primary research focuses on fertility preservation (oncofertility) in adolescent and adult male patients with cancer. The overall goal of his research is to raise awareness of the issue of fertility preservation and facilitate access to care. He has reported the significant knowledge gap among pediatric oncology providers regarding fertility preservation recommendations for oncology patients and concurrently published a manuscript in Cancer promoting methods to incorporate fertility preservation care into the care of young oncology patients. He has also reported on the improvement in fertility preservation care coinciding with the establishment of a formalized fertility preservation care program at Northwestern. He continues to publish research to assist clinicians at other institutions looking to establish their own fertility preservation programs, including examining the preferences and perspectives of adult survivors of pediatric cancer regarding fertility preservation.
