Frances Hayes, MBBCh, BAO, associate clinical chief of the Division of Reproductive Endocrinology at Mass General, has dedicated herself to researching human reproductive physiology. Along with research, her clinical work involves providing consultation to patients with reproductive disorders such as infertility and menstrual disorders. She also helps lead the Transgender Health Program, which provides comprehensive, multidisciplinary care to transgender individuals.

Dr. Hayes is an expert in male hypogonadism, a condition that impairs the production of testosterone. Her research studies have revealed the insulin resistance is associated with a decrease in testosterone production. Along with her research and clinical work, Dr. Hayes is passionate about mentoring young clinicians as an associate professor of Medicine at Harvard Medical School and an advisor for premedical students at Harvard College.
