USA Boxing, the governing body of the sport in the United States, is being slammed for its new transgender policy that allows biological men to compete against biological women.

Under the new policy, included in the 2024 rule book, male boxers who transition can compete in the female category so long as they meet certain criteria.

Those under the age of 18 are still required to compete as their birth gender, but adults can choose their category as long as they state their new gender identity and fully complete gender reassignment surgery.

Transgender athletes must also participate in regular hormone testing.

Boxers who transitioned into women are required under the new policy to have testosterone levels under five nanomoles per liter for three years prior to their first competition in the “female” category, and their total testosterone levels must be below five nmol/L throughout their period of eligibility.

Those competing as men, meanwhile, must show levels about 10 nmol/L for the same period.
