A senior pediatric endocrinologist at a leading medical school in Canada has for years provided the introductory lecture on Disorders of Sex Development/Intersexuality (DSD/I) in the standard second-year course. In 2020/2021, two students complained to medical school administrators about six specific issues of intersex theory and care that were addressed in the lecture (Polychronakos, 2021). Subsequently, the administration replaced the professor with a different lecturer, thus effectively censoring the dissemination of intersex science. An overview of the status of the clinical literature on intersexuality shows that the students’ critiques focus on concepts and facts that have been developed in extensive medical and sexological research over the past 50–60 years, as is shown for each of their points of critique. By censoring the professor’s teaching, the medical school not only violated academic freedom, but also suppressed well-established scientific facts, kept medical students uninformed about the diverse points of view in this area of clinical management, and likely undermined future evidence-based medical and psychosocial care by these students for individuals with this type of medical condition.
