RESUMO
This review starts with a brief history of sex policy in sport followed by an exploration of the current state of transgender sport policies. Transgender in sport, from the high school to the professional level, is a frequent news topic. Fairness in women's athletics is at the center of transgender sport policy deliberations and public debate. Despite a long history of policy attempts and revisions, the female category in sport is not precisely and universally established, complicating transgender athlete policy development. Scientific evidence is scant on fairness for transgender athletes. For a variety of social factors, many transgender athletes do not have a positive experience in sports and the younger is the athlete the more challenging it becomes to create inclusive rules. Challenges remain in making competition rules fair, but inclusive, so that transgender athletes participate in sport. The medical and scientific community will continue to provide key input.
