Current college & professional standard is that men have to be taking women’s hormones for 6 months before competing on a women’s team. Looks like that’s not enough to make a level playing field. Even 3 years isn’t enough. ETA: also for women wanting to compete on a men’s team, though that’s less common & even with hormones they won’t measure up.


Maybe there’s no way at the moment to make men and women completely interchangeable, and maybe that isn’t a bad thing.


Do most trans women want to have less muscle?


I wonder what would happen when compared to children who have taken puberty blockers.


Very interesting! I used to be into bodybuilding as a guy (look on my profile for before and after transition pic) and even though I lost a lot of muscle mass I am still very strong, even compared to guys who are a similar weight to me. Thanks for posting 🙂
