Current Olympic rule on trans:
“The current Olympic rules acknowledge transgender athletes' right to compete, but with specific provisions under the Stockholm Consensus, which was adopted in 2004. The policies, adopted before the Athens Olympics, say transgender athletes have to have gender reassignment surgery and have legal recognition of the gender they were assigned at birth.”
The
proposed Olympic policy change:
“…would allow transgender athletes to compete without having gender reassignment surgery. It only requires athletes to have completed at least one year of hormone replacement therapy.”
And
“The policy change would be in line with NCAA standards in the United States, which allow male-to-female and female-to-male transgender athletes to compete without having gender reassignment surgery, according to
ESPN “
