many indigenous cultures, such as the Navajo, there was a recognition of more than two genders long before modern discussions about transgender rights. These cultures often had roles for people who didn't fit neatly into male or female categories, and they were fully integrated into society, including sports and competitions.

Moreover, we've seen that hormone therapy can bring transgender athletes within the same range of physical capabilities as cisgender athletes of their identified gender. For example, MMA fighter Fallon Fox, a trans woman, underwent hormone therapy and has competed professionally against cisgender women.
