Can’t believe you’re being downvoted a lot. Any trans woman person on medication for long enough will just simply not have the muscle mass they had before. It’s basic science.
I mean if people were really that concerned, which I imagine they aren’t and just want to discriminate, you could just ensure they took medication for several years above a certain amount using blood tests. Not sure if they do currently, but they should probably do that for testosterone too.
Then it gets even weirder because sports aren’t defined by gender anymore but by hormones, but maybe that actually makes more sense? As that affects what muscle you can build?
