Male-born person wants to play on the women's team, women are expected to move over and allow this. It's quite a contrast with what happens when a female-born person transitions.
Different sport and country, but this is what happened to one such person. Kian was born female:
Throughout his childhood, Kian and his twin sister played hockey on girls’ recreational and competitive teams. When Kian started transitioning, he didn’t want to play with the girls anymore, so he went to play with the boys on a house league team.
Kian said he was treated poorly by his teammates and coaches. Even other parents started talking about him behind his back.
The last straw came when his teammates locked him in the bathroom at an away game.
“They were saying, ‘Oh yeah, it was an accident,' or 'It was just a joke, like, he knew.’ And the coach was like, ‘It wasn't a joke.’ He knew that they had locked me in there. And I went out, played that game, came back in, changed and that was the last game I ever played," Kian said. "I just kind of said ... ‘Goodbye, I don't need this.’”
That’s when Kian quit the game he loved.

In short, girls and women always lose out.
