FIFA call it a “therapeutic use exemption”, which basically anybody can get with a note from a doctor. A lot of other sports have similar exemption processes. I know the NFL does too.

In my quick research on this, the TUE process appeared to be quite strict, and definitely not an easy "you just need a note from a doctor" kind of thing. For example, in the NFL, the only example I could find where they'd give a testosterone exemption is if you had testicular cancer and had removal of 1 or both testes, which seems reasonable. I also found examples where both the NFL and FIFA had recently suspended players for testosterone use.
If you have any other examples or sources that counter this info, I'd be very interested to see it.
You can’t find examples because the treatments are part of the players private medical records and are not published. But it is as simple as getting a doctor to say that therapeutic use is required.
