The Olympics have this solved. Trans women have been allowed to compete for the last 20 years as long as they’ve been on HRT for at least 2 years and have hormone levels in the expected range. The results plainly show there’s no advantage, and possibly even a disadvantage. The only trans person to win a medal was an AFAB nonbinary soccer player who wasn’t taking hormones, and the only trans woman to compete in an event came in dead last. No other trans athletes made it past qualifiers.
