What I don’t get is why don’t men who wish to be elite sportsmen AND wish to transition, just put it off till their peak competitive days are over?
Female athletes (not always, but very often) have to put motherhood on hold as they know it will disadvantage them in their sporting careers (time off for pregnancy and recovery, disrupted training regime due to caring responsibilities, etc).
The whole point is that some times you have to make a choice, you can’t have your cake and eat it!
