UPenn transgender swimmer Lia Thomas s sporting future was called into question on Tuesday after USA Swimming ruled that female athletes must have at least 36 months of low testosterone levels.
One of Thomas teammates, who spoke on a condition of anonymity, said administrators are considering legal action after a rule change that will force Thomas to document testosterone levels.
The father, who has also chosen to remain anonymous to avoid physical harm and has a medical background, said he believes there is no stopping Thomas from reaching the highest level.
