question about what specify as "special genders"

according to the other thread idk if its true or not
"In the VCT GC rules it states that the maximum number of "specific gender" players is 2"

what specify as "spesific gender"? in olympics athletes got tested for their hormonal percentage so they can pass women class. does riot do any of this?

also its not about the advantage its more about what pass the female category
