"She can try hormones, chop her pecker off, but it's still the same bone structure a man has," Rousey told The Post. "It's an advantage. I don't think it's fair."
"I understand the UFC doesn't want to be associated with views like (Mitrione's)," Rousey said. "I'm also glad they didn't straight cut him."
Rousey told the post she had competed against hermaphroditic athletes in Judo and had no problems because "that was something they didn't choose" but she feels Fox is in a different category because it's a situation of her own making.
"It's not something that happened to her," Rousey said. "It was a decision she made. She should be aware in her career after that, it's going to be an arduous path. I don't know why she's surprised by that. It's going to draw a lot of emotions."
Rousey would prefer not to fight Fox, but she would if the UFC insisted.
"What if she became UFC champion and we had a transgender women's champion?" Rousey said. "It's a very socially difficult situation."
