I'd guess that people who aren't clearly male/female would probably tend to be grouped in the more competitive category. For example, say that an intersexed-athlete (not simply male nor female) plays two sports: one where males are seen as advantaged and another where females are seen as advantaged. Then, the intersexed-athlete would probably compete in the male-category in the male-advantaged sport while simultaneously being in the female-category in the female-advantaged sport.
