Mack Beggs, the transgender boy who won a state girls' wrestling title in Texas, said he cut his doses of testosterone while he transitions so he wouldn't gain an unfair advantage.
"I want to do it fairly," Beggs said in an interview aired Sunday on ESPN. "I don't want to cheat. That's not something I do. I don't cheat."
Beggs wrestles against girls because a state wrestling rule requires wrestlers to compete against those who match the gender on their birth certificate, rather than their gender identity.
Beggs never lost a match en route to his victory in the 110-pound weight class.
He said he had asked the University Interscholastic League if he could compete against boys. That request was denied, but he was allowed to take testosterone while he transitions.
Jim Baudhuin, a Dallas-area attorney and wrestling parent, has sued to keep Beggs from wrestling girls. Many complained that wrestling against Beggs was unfair.

It's not like I'm doing this because I want to, like, call myself a boy and just dominate all these girls. What do I get out of that?
Beggs said wrestling became an outlet for him as he struggled with gender identity, but he doesn't have any interest in taking advantage of his transition.
Mack Beggs is nothing more than a dyke on roids. Shooting testosterone is the equivalent of a male using roids. He is a disgrace— Tech-Redsox (@redsox_tech) February 26, 2017
Some who saw Beggs wrestled thought he was cheating.
The response to Mack Beggs, the trans male teen who won the girls wrestling competition, literally shows just how transphobic people are.— aj (@crucifalex) February 26, 2017
But some critics argued Beggs' critics were transphobic.
Some found the argument against him using testosterone hypocritical.
Others tied the controversy to the recently reignited transgender bathroom debate.
