Not a doctor or a trans woman, but from what I understand, you lose the physical advantages of self-produced testosterone over time.
Additionally, it’s not as simple as “hormone levels.” Some AFAB women have higher than normal levels of testosterone, and some AMAB men have higher than normal levels of estrogen (and/or just lower testosterone levels). There will always be athletes who have biological advantages, whether that’s a bigger heart, better lungs, longer/shorter legs, better eyes, stronger bones, etc.
We draw these boxes around perceived genders as if that’s a guarantee of fairness, but it’s not some panacea that effectively separates the able from the unable, just like gender is more than your genes.
