Laurel Hubbard to become first transgender athlete to compete in Olympics

• Hubbard competed in men's weightlifting until she transitioned in 2012, and she's been eligible to compete as a woman since 2015, when the IOC issued new guidelines.
• Those guidelines allow transgender athletes to compete as women as long as their testosterone levels are below 10 nanomoles per liter for at least 12 months before their first competition.

The backdrop: Hubbard's gold medal wins at the 2019 Pacific Games in Samoa triggered outrage, and Australia's weightlifting federation unsuccessfully sought to block her from competing in 2018.

• Earlier this year, American transgender powerlifter JayCee Cooper sued USA Powerlifting after it barred her from competition through policy that was at odds with IOC guidelines.
