In this article, I argue that there are moral reasons to embrace the construction of self-designing and sex/gender-neutral cyborg athletes. In fact, with the prospect of advanced genetic and cyborg technology, we may face a future where sport (as we know it) occurs in its purest form; that is, where athletes get evaluated by athletic performance only and not by their gender, and where it becomes impossible to discriminate athletes based on their body constitution and gender identity. The gender constructions (...) within sports and sports culture are solid, however. Here, I argue that the rough distinctions we use to define people in terms of sex/gender tend to create and recreate old-fashioned and discriminatory sex/gender-boundaries. A morally reasonable way of meeting this issue, is to say that the problem is not the individuals who (for one reason or another) transcend certain gender categories, but the categories in themselves.
