Lin Yu-Ting is female and has been female since childhood.
What is terrifying is that J.K. Rowling, wielding her influence and always using a frantic approach, completely disregards the possibility of making mistakes and relentlessly attacks our athlete.
Yesterday, the incident involved an Italian athlete who felt that the punches from Algerian athlete Khalif were too heavy and said she "did not want to compete against a male," so she withdrew. Khalif is one of the athletes who had disputed biochemical data in their previous IBA tests with Lin Yu-Ting.
However, in the current International Olympic Committee (IOC) examination, both athletes were found to be completely normal. The IBA, which had previously disqualified them, has been suspended due to issues with unfair judging and corruption. The IBA was stripped of the status by the International Olympic Committee in June 2023.
Moreover, the IBA president "claimed" that these two athletes have XY chromosomes, but they "never actually tested chromosomes" and only "tested biochemical data."
So the IBA president was "guessing."
How can someone with XY chromosomes have normal testosterone levels in the Paris Olympics and other events, including the Tokyo Olympics?
Did they somehow remove their testes during blood tests and then put them back in for the competition?
It is natural for athletes to not be allowed to administer additional testosterone, so normal blood tests before the competition are expected. What more do you want to question?
Additionally, testosterone levels in females can naturally increase without medication, including a condition called DSD (Differences in Sex Development). Studies suggest that 7 out of every 1,000 female track athletes have DSD, with higher testosterone levels than typical females. However, medicine has yet to prove that testosterone levels are the absolute key to winning in sports. [1]
Next, let's talk about chromosomes. Did you know that some people's cells have a "45,X/46,XY mosaicism" ? [2]
Furthermore, men can lose Y chromosomes from many cells with age. This phenomenon is considered increasingly common. [3]
While you are defaming athletes who have been female since childhood, some of your cells might be silently undergoing changes you aren't aware of.
Rules for the world's highest-level competitions are not determined by novelists but by professional medical teams and the Olympic Boxing Working Group (PBU).
Our athletes are competing legally and in compliance with regulations. I will continue to support them, and Lin Yu-Ting also needs your efforts to debunk the rumors and full support! Go Yu-Ting!
