New Zealand weightlifter Laurel Hubbard made history on Monday as the first openly transgender female athlete to compete at the Olympics.

Why it matters: The presence of trans and nonbinary athletes at this year's Games has been celebrated by LGBTQ+ rights advocates, but stirred controversy among critics, who argue trans women have an unfair advantage even after taking hormones to lower their testosterone.

• The science on that belief is inconclusive. Also, non-transgender women also have a wide range of naturally occurring testosterone levels.
• Hubbard, 43, competed in male weightlifting before transitioning at age 35. She qualified for the Tokyo Games in the 87+ kg category after completing the required rules for trans athletes, including suppressing her testosterone levels below a proscribed level (10 nmol/L) for at least a year.

The latest: Hubbard failed to successfully complete any of her three lifts in the snatch portion of the event. She made a heart sign with her hands after her third lift and mouthed "thank you," making history even as she crashed out of the Olympics early.

Be smart: Athletes in Olympic weightlifting compete in two disciplines: snatch, followed by clean and jerk, with the highest combined totals earning the medals.

• Hubbard is among 10 athletes competing tonight, along with several others who did their lifts earlier in the day.

What she's saying: "I see the Olympic Games as a global celebration of our hopes, ideals and values and I would like to thank the IOC for its commitment to making sport inclusive and accessible," Hubbard said in a statement read on her behalf at an International Olympic Committee briefing last week.
